Disease detection on the plant leaves by deep learning
Plants disease detection is very popular field of study. Many promising results were already obtained but it is still only few real-life applications that can make farmer’s life easier. The aim of our research is solving the problem of detection and preventing diseases of agricultural crops with the help of deep learning. We collected a special database of the grapes leaves consisting of four set of images, including healthy, Esca, Black rot and Chlorosis diseases. We reached over 90% accuracy using a deep siamese convolutional network. Comparative results of using various models and plants are presented.

Single trial EEG classification of tasks with dominance of mental and sensory attention with deep learning approach
In this paper, we present classification algorithms based on single-trial ElectroEncephaloGraphy (EEG) during the performance of tasks with the dominance of mental and sensory attention. Statistical data analysis showed numerous significant differences of EEG wavelet spectra density during this task at the group level. We decided to use wavelet power spectral density (PSD) computed in each channel for single trial as the source of feature extraction for the classification task. To obtain a low-dimensional representation of PSD image convolutional autoencoder (CNN) was trained. With this encoded representation binary classification for each subject with multilayer perceptron (MLP) were performed. The classification error varies depending on the subject with the average true classification rate is 83.4\%, and the standard deviation is 6.6%. So this approach potentially could be used in the tasks where pattern classification is used, such as a clinical decision or in Brain-Computer Interface (BCI) system

Temporal discounting in the goal-directed behavior model
The model of modification of state value map is considered, supplemented with temporal discounting instruments. It is shown that taking into account the state value discounting results in more “reasonable” goal-directed behavior. Modifiability of the discounting rates leads to differentiation of the short-term goals associated with urgent needs satisfaction and the long-term goals corresponded to strategically comfortable states.

CHANGES IN DYNAMICAL COMPLEXITY OF TREMOR WITH INCREASING THE MOTOR DISTORTIONS
The task is to test the hypothesis that dynamical complexity of patterns of the human hand tremor accompanied the motor task performance decreases with increasing the disease severity. For solving the task the tremor patterns are examined by the wavelet-transform modulus maxima method and the recur-rence quantification analysis. Our results demonstrate that the dynamical com-plexity of tremor patterns decreases in larger degree for Parkinson’ disease, than for patients with the syndrome of the essential tremor, that is, it declines with increasing the severity degree of motor disorders.

Epileptic Seizure Propagation Across Cortical Tissue: Simple Model Based On Potassium Diffusion
Mechanisms of epileptic discharge generation and spread are not well known. Recently proposed simple biophysical model of interictal and ictal discharges is generalized here to the case of spatial propagation. Diffusion of the extracellular potassium concentration is assumed to govern the spatial spread of spiking activity across cortical tissue. Simulations are consistent with experimental registrations of waves in pro-epileptic conditions, propagating at a speed of about 0.5 mm/s.

Spatial and temporal dynamics of EEG parameters during performance of tasks with dominance of mental and sensory attention
The purpose of this work was to analyze the spatial and temporal dynamics of EEG parameters during performance of tasks with dominance of mental and sensory attention. In addition, an attempt to identify differences in dynamics of EEG parameters in such close mentally oriented tasks as a productive and reproductive imagination was made. EEG wavelet spectra and phase coherence (relationships between EEG-channels) were studied for theta, alpha1, 2 and beta1, 2 frequency ranges of EEG. Analysis of the data showed significant numerous differences of EEG wavelet spectra and phase coherence between tasks with the dominance of mental and sensory attention and also between such close mental states as productive and reproductive imagination. Time dynamics of EEG differences, obtained in different frequency ranges, allows us to trace which processes were consequentially involved in realization of investigated states on different time intervals and provide new information for understanding of brain mechanisms of these states.

An asynchronous approach to discrete modeling of nonsinaptic interac-tions between neurons
An asynchronous discrete model of nonsynaptic interactions between neurons is proposed. In the model, neurons interact by emitting neuro-transmitters to the shared extracellular space. We introduce dynamics of membrane potentials that comprises two factors: the endogenous rates of change depending on the neurons firing type and the exogenous rate of change, depending on the concentrations of neurotransmitters that the neuron is sensitive to. Differences in endogenous rates of different neurons leads to asynchronous neural interactions and significant variability of phase durations in the activity patterns. The algorithm computing the behavior of the proposed model is provided.

Interaction of neural elements of the auditory system in the analysis of signals with noise amplitude modulation
The results of the study of correlations between the reactions of single neurons of the auditory center from the middle brain of the tra-vyan frog in the process of coding of tonal signals modulated by repetitive segments of low-frequency noise amplitude modulation are presented. Registration of activity of nearby cells is carried out using the classification of neurons in the form of spike. Along with the study of the activity of each of the selected cells, the interdependence of neural elements registered by one microelectrode is investigated, the task of assessing their mutual correlation is carried out. It is found that in most of the selected pairs of cle-current in the presence of a pronounced correlation determined by the influence of sound, the internal correlation independent of the signal is weakly expressed

A GENERAL PURPOSE ALGORITHM FOR CODING/DECODING CONTINUOUS SIGNAL TO SPIKE FORM
An algorithm called Symmetric Integro-Differential Conversion (SIDC) serving to encode continuous real-valued signal to spike form is described. One dynamic numeric signal is converted to 4 spike trains. 2 spiking signal lines serve as a low-pass filter, while 2 other play the role of high-pass filter. This approach allows accurate encoding signals with high variability of spectral properties. A reverse conversion algorithm is proposed which is used to assure that the resulting spike signal preserves information about the original signal to a sufficient extent.

Homotopy Continuation Training Method for Semi-Empirical Continuous-Time State-Space Neural Network Models
Recurrent neural networks present a powerful class of nonlinear dynamical system models that hold great potential for real-world applications. However, the traditional gradient-based optimization methods often fail to find a sufficiently good solution unless the initial guess for parameter values lies very close to it. We propose a training method based on the homotopy continuation approach with variable prediction horizon which allows circumventing this issue. Simulation results confirm the efficiency of this training method.

Neural Network Based Semi-empirical Models of 3D-Motion of Hypersonic Vehicle
We consider the problem of mathematical modeling and computer simulation of nonlinear controlled dynamical systems represented by differential-algebraic equations of index 1. The problem is proposed to be solved in the framework of a neural network based semi-empirical approach combining theoretical knowledge for the object with training tools of artificial neural network field. Special form neural network based semi-empirical models implementing an implicit scheme of numerical integration inside the activation function are proposed. The training of the semi-empirical model allows elaborating the models of aerodynamic coefficients implemented as a part of it. A semi-empirical model using as theoretical knowledge the equations of the full model of the hypersonic vehicle motion in the specific phase of descent in the upper atmosphere are presented. The results of simulation for the identification task for the aerodynamic lift coefficient implemented as an ANN-module of the semi-empirical model of the hypersonic vehicle motion are presented.

Neural Network Recognition of the Type of Parameterization Scheme for Magnetotelluric Data
The inverse problem of magnetotelluric sounding is a highly non-linear ill-posed inverse problem with high dimension both at the input and at the output. One way to reduce the incorrectness is to narrow the scope of the problem. In our case, this can be implemented in the form of a complex algorithm, which first makes the choice of one of the narrower classes of geological sections and then performs the solution of the regression inverse problem within the selected class. In the present study, we investigate the effectiveness of the implementation of the first phase of this algorithm. The neural network solution of the problem of classification of magnetotelluric sounding data was considered. We estimate the maximum accuracy of classification, perform search for optimal parameters, and test the results for resilience to noise in the data

TEMPERATURE FORECASTING BASED ON THE MULTI-AGENT ADAPTIVE FUZZY NEURONET
This article presents a multi-agent adaptive fuzzy neuronet for the average monthly ambient temperature forecasting. The agents of the multi-agent adaptive fuzzy neuronet are fulfilled based on two-layered neural network. An automatic generation of the optimal architecture’s parameters of a neuronet is the most complex task. In order to train the effective multi-agent adaptive fuzzy neuronet we modified the Ant Lion Optimizer and combined it with the Levenberg-Marquardt algorithm. The simulation results show that the proposed training algorithm outperforms modified Ant Lion Optimizer and Levenberg-Marquardt algorithms in training the effective multi-agent adaptive fuzzy neuronet for the average monthly ambient temperature forecasting.

Algorithm for synthesis of an inverse neurocontroller
The problem of constructing a neurocontroller for a dynamic plant is considered. The synthesis algorithm is implemented on the basis of the concept of the inverse model and the given reference process. The inverse model is used to obtain information on the reference control signal necessary for training the neurocontroller. The neural controller is built on the basis of a feedforward neural network with delay lines for input to the output signal. The synthesis procedure involves several consecutive steps. At the first step, the control plant is identified, the neural network traced using the back propagation algorithm is used as the model. The same algorithm is used in the second step to synthesize the inverse model of the control plant. With the help of this model, the third step prepares data for training the neurocontroller in the fourth step of the algorithm. The results of a computational experiment in Simulink MatLab for determining the parameters of a neural controller for a second-order dynamic link, which confirm the practical utility of the proposed approach for a wide range of control plants, are presented.

AGI developers manifest project
Objective obstacles to AGI (artificial general intellectence) are the physical world nonlinearity phenomena and the curse of dimension. The subjective difficulties are the lack of common views on the ways and goals of AGI creating. The complexity implies a collective approach to problem solving. It is necessary not only to identify ways of achieving AGI, but also to coordinate views among developers. It is proposed to discuss and improve the list of fundamental principles for AGI creation.

Bursting in a system of two coupled pulsed neurons with delay
The system of two singularly perturbed differential-difference equations with delay modeling the synaptic interaction of a pair of pulsed neurons is considered. The connection between elements is selected threshold, taking into account the time delay. In the framework of the problem an algorithm for finding periodic solutions with bursting behaviour is proposed. The appearance of such relaxation oscillations in the system is a consequence of delay in the communication circuit between the oscillators. Of particular importance is the fact that the system can have a large number of coexisting relaxation oscillations.

FUNCTION AND MOLECULAR DESIGN OF THE SYNAPSE
The majority of excitatory synapses in the mammalian forebrain and the hippocampus incorporate dendritic spines. Even though their intricate molecular composition remains obscure in many aspects, available evidence suggests that these structures are highly specialized to support the short- and long-term plasticity crucial for flexible information processing. One concept that is extensively used to describe synaptic function is the Hebb’s postulate. However, the knowledge accumulated throughout following decades advocate for a broader scale in intercellular connection functions. Synaptic activity depends on interactions among sets of proteins (synaptic interactome) that assemble into complex supramolecular machines. Molecular biology, electrophysiology, and live-cell imaging studies have provided tantalizing glimpses into the inner workings of the synapse, yet fundamental questions regarding the functional organization of these “molecular nano-machines” remain to be answered. The presence of accessory receptors for secondary messengers in synapses along with receptors for primary mediator gave us the idea that these molecular constructs could be responsible for initial processing of the incoming signals. The purpose of this initial processing could be determined by analyzing and reconstructing this molecular informational machine that postsynaptic zone essentially is.

WHY SHADOWS, WHICH CREATE THE "SPECIFIC VISION DEFICIT" SPOT, DO NOT MANIFEST THEMSELVES UNDER NORMAL CONDITIONS OF VIEW: AN ANALOGY WITH THE "BLIND SPOT"
A manifestation of the "specific vision deficit" (SVD) phenomenon is the visible structured spot (SVDs-image) at the position of a bright point light source, placed on a shaded background. SVDs-image is created due to the shadows presence in the projection of a bright source on the retina; shadows (Sh) created due to heterogeneities (H) in the eye transparent structures. However, in normal circumstances we do not see any evidence of the HSh, even if the visual space is a bright white screen. Here is an attempt to analyse this observation.

Functional neural networks in behavioral motivations
Functional magnetic resonance imaging (fMRI) is an effective non-invasive tool for exploration and analysis of brain functions. Here functional neural networks involved in behavioral motivations are studied using fMRI. It was found that behavioral conditions producing different motivations for action can be associated with different patterns of functional network activity. At the same time, connection can be made to dynamics of socio-emotional cognition, decision making and action control, described by the Virtual Actor model based on the eBICA cognitive architecture. These preliminary observations encourage further fMRI-based study of human social-emotional cognition. The impact is expected on the emergent technology of humanlike collaborative robots (cobots) and creative cognitive assistants.

Semantic Space and Homonymous Words
Significant differences were found in the organization of electrobiological responses of the brain to the words-homonyms, presented in different meanings by priming a certain context in the electrophysiological experiment on a sample of 14 people As a result of comparison of series before and after negative reinforcement by the method of Semantic Radical of the word entering the semantic field of one of the two studied meanings of the word-homonym, the fact of indirect long-term influence of the emotional component is revealed. This is manifested not only in the change in the meaning of the homonym word (presented in the relevant context) in the late latency (300-500 MS) in the frontal leads, but also in the reconfiguration of its meaning in a non-relevant context (in the earlier – 200 MS – latencies in the central leads). Thus, the results objectively indicate the possibility of two types of reconfiguration of the semantic map (space) 1) operational reconfiguration to the current context defined in this experiment by the corresponding prime, and 2) long-term reconfiguration determined by the control action

MULTICENSORY INTELEGENT EARLY WARNING SYSTEM FOR FIRE DETECTION ON SHIPS
The purpose of the study is to develop a multi-sensor intelligent early warning system for fire detection on the ship. An evolutionary algorithm for the optimal placement of sensors controlling such fire factors as temperature, concentration of carbon dioxide, carbon monoxide and the presence of smoke is pro-posed. It is proposed to use the evolutionary algorithm to determine the optimal coordinates of the sensors of the multi-sensor fire system, depending on the position of the source of ignition. Based on the results of modeling, the possibility of determining the type of source of burning was substantiated. Determination of the type of ignition source allows you to respond quickly and correctly to the onset of fire extinguishing. This can reduce the damage from it.

Hopfield Associative Memory with Quantized Weights
The use of binary and multilevel memristors in the hardware neural networks implementation necessitates their weight coefficients quantization. In this paper we investigate the Hopfield network weights quantization influence on its information capacity and resistance to input data distortions. It is shown that, for a weight level number of the order of tens, the quantized weights Hopfield-Hebb network capacitance approximates its continuous weights version capacity. For a Hopfield projection network, similar result can be achieved only for a weight levels number of the order of hundreds. Experiments have shown that: 1) binary memristors should be used in Hopfield-Hebb networks, reduced by zeroing all weights in a given row which moduli are strictly less than the maximum weight in the row; 2) in the Hopfield projection networks with quantized weights, multilevel memristors with a weight levels number significantly more than two should be used, with a specific levels number depending on the stored reference vectors dimension, their particular set and the permissible input data noise level.

Match-Mismatch Detection Neural Circuit Based on Multistable Neurons
An ability to detect matches and mismatches between the real world and its representation are both crucial for intelligent autonomous systems to work efficiently. Here we recall our previously proposed model of the neuron which activation characteristic (dependence between an input pattern and output signal) depends on the value of the modulation parameter and varies from a smooth sigmoid-like function to the form of a quasi-rectangular hysteresis loop. Then we propose the neural circuit based on this model of multistable hysteresis neuron. Such a neural circuit can compare expectations represented by downward signals and reality represented by upward signals. In case of matching between them the neural circuit transfers both up and downward signals. In another case, internal inhibitory neurons are activated, and transferring becomes blocked until the expected conditions are met. Besides, the changes in the modulation parameter allow fine-tuning the behavior of this neural circuit. In the end, the results of the numerical simulation are presented.

Spectral density of 1D Ising Model in n-vicinity method
For the 1D-Ising system we obtain an exact combinatorial expression for the spectral density in the n-vicinity of the ground state. We compare the obtained expression with the normal approximation of the spectral density that is usually used in the framework of the n-vicinity method. We discuss the reasons why the n-vicinity method does not work in the case of the 1D-Ising system.

Spiking Neural Networks learning based on a neuron activity maximizing principle
We propose a simple idea of bioinspired local dynamic rules for changing the synaptic weights of a spiking neural network (SNN) based on LIF-neurons that can be used with or without a teacher. We assume that each neuron in the biological neural network tends to maximize its activity, and we transfer this principle to the SNN training algorithm. The spiking neural network with trained forward, reciprocal and inhibitionconnections was tested on MNIST dataset; recognition accuracy 95% was obtained.

MODELING CONSCIOUSNESS: GENERATION OF GOALS AND HOMEOSTASES
The properties of conscious actions are difficult to reconcile with the fundamental laws of nature. There are different goals of behavior, the main of which is the achievement of the preservation of the life. This is function of homeostasis. Damage to neurons provokes the turning on homeostasis and causes an elementary negative sensation. The article argues that the tension of homeostatic compensation can lead to the generation of targeted actions. The question arises whether it is possible to organize consciousness in an artificial system? We answer this question positively and describe the way to solve the problem.

A model of temporary changes of optimal orientation in primary visual cortex neurons
as was shown in experiments a peak orientation in primaru visual cortex neurons systematically changes during the response time course. However, such orientation shifts don't reproduce by majority of modern biophysical models.

Artificial Neural Networks for Diagnostics of Water-Ethanol Solutions by Raman Spectra
The present paper is devoted to elaboration of a method of diagnostics of alcoholic beverages using artificial neural networks: the inverse problem of spectroscopy – determination of concentrations of ethanol, methanol, fusel oil, ethyl acetate in water-ethanol solutions – was solved using Raman spectra. The following accuracies of concentration determination were obtained: 0.25% vol. for ethanol, 0.19% vol. for fusel oil, 0.35% vol. for methanol, and 0.29% vol. for ethyl acetate. The obtained results demonstrate the prospects of using Raman spectroscopy in combination with modern data processing methods (artificial neural networks) for elaboration of an express non-contact method of detection of harmful and dangerous impurities in alcoholic beverages, as well as for the detection of counterfeit and low-quality beverages.

Linear Filtering Based on a Pulsed Neuron Model with an Orthogonal Filter Bank
This paper deals with the model and learning rules of a pulsed neuron, which provide the linear filtering of signals represented by pulse trains. To reduce the number of training parameters of a pulsed neuron we propose using a bank of orthogonal filters as a model of synaptic connections. For this model of pulsed neuron, we derive a supervised learning rule in a general form that can include various orthogonal basis functions. The rules minimize the mean square error between the desired and the actual output signal of a linear filter realized on the base of the pulsed neuron model. We derive two special learning rules: with set of exponential complex orthogonal functions and set of block-pulse orthogonal functions. For both set of these functions, we demonstrate rule’s properties by computer simulation of linear filters that implement high-pass filtering and double integration of the input signal transformed to pulse train. We show the impulse and frequency responses of the filters as well as the dependencies of the normalized mean square error on the number of training iterations.

On Comparative Evaluation of Effectiveness of Neural Network and Fuzzy Logic Based Adjusters of Speed Controller for Rolling Mill Drive
The article deals with a problem of speed control of a DC electric drive of a re-verse rolling mill under the conditions of its mechanics parameters drift and influ-ence of disturbances. The analysis of existing methods to solve it is made. As a result, two intelligent methods are chosen – the neural network (proposed by the author) and the fuzzy logic based tuners of linear controllers, the efficiency of which is to be compared. The neural tuner consists of two neural networks calculating the controller parameters of the electric drive, and a rule base that determines at what moments and speed to train these networks. A general description of the fuzzy tuner is also provided. Experimental studies are made using a model of the electric drive of the rolling mill under the above mentioned conditions. The obtained results show that the neural tuner, contrary to the fuzzy one, keeps the speed overshoot within the required limits and also reduces the time of disturbance rejection by 30%.

Semi-Supervised Vowel Classification with Additive Noise by the Response Patterns of Auditory Nerve Model through the Label Propagation in Emergent SOM
The paper proposes an approach to stationary patterns of auditory neuronal activity analysis from the point of semi-supervised learning in self-organizing maps (SOM). The suggested approach has allowed to classify and identify complex auditory stimuli, such as speech vowels, given limited prior information about the data. A computational model of the auditory periphery has been used to obtain auditory nerve responses. Label propagation through Delaunay triangulation proximity graph, derived by SOM algorithm, is implemented to classify unlabeled units. In order to avoid the dead unit problem in emergent SOM and to improve method effectiveness, an adaptive conscience mechanism has been realized. The study has considered the influence of AWGN on the robustness of auditory stimuli identification under various SNRs. The representation of acoustic signals in the form of neuronal activity of the auditory nerve has proven more robust compared to that in the form of the most common acoustic features, such as MFCC and PLP. The approach has produced high accuracy classification, both in case of similar sounds and with high SNR.

FMRI and tractographic studies of cognitive systems in the human brain at the norm and the paranoid schizophrenia
This study is aimed at a systematic study of the work of neural networks of the human brain and their architecture in norm and in schizophrenia. To obtain the neurophysiological data, a unique complex of experimental equipment for world-class neurocognitive studies was used. The data obtained showed a significant decrease in the structural connectivity relationships for the rich club coefficient for a group of schizophrenic patients compared with the norm. Perception of emotionally negative visual and audio stimuli related to delusions in patients with schizophrenia does not lead to a significant decrease in BOLD signal as compared with the norm in Calcarine_L, Cerebelum_4_5_R, ParaHippocampal_LR, Precuneus_L, Temporal_Sup_R areas. The differences found in the structural and functional patterns of cognitive-affective disorders can serve as prognostic biomarkers in patients with schizophrenia and will make a significant contribution to the development of high-tech diagnostics in the early stages of mental illness

The principle of implementing an assistant composer
The task of developing an assistant composer is a very interesting task, as the composer's work is complex and creative. Lately there has been done a lot of research, devoted both to systems that help composers to write melodies and systems that generate melodies. In the case of melody generating, the system o ers a composition based on some rules embedded in it according to the musical theory, or obtained by analyzing a large number of compositions with the help of neural networks, while the assistant's task is to other its ideas that can help composer with creating the work of music. In this article the basic interaction between the composer and the assistant, who helps with writing the melody, is considered. The melody itself can be conditionally divided into two com- ponents: the main melody (the main theme, the main idea of the work), and its accompaniment (the decoration of the main melody). Accordingly, the composer's assistant can help with composing both the main melody and its accompaniment. In this article we consider possible problems that the composer may encounter with while composing melodies,as well as possible ways of implementing an assistant which will be able to solve them.

On the memory consolidation in the brain neuronal net
There are two types of memory - short-term and long-term ones. First, the former arises and then the latter one (in the course of the so called consolidation process). Own neuronal networks (engrams) in the brain correspond to each of those memories, and our goal is to understand what is the difference between those networks from viewpoint of their structural properties. It is not about the special biochemical structure of some neurons or synapses arising under the memory consolidation, but about some total topological properties of those brain networks which are associated with the stored pattern. In other words, could the topological reconstruction of the neuronal network promote the memory consolidation and transfer it into the long-term form? The model consideration of that phenomena shows that such a process is quite possible. For that to happen, two conditions have to be met: i) the neuronal net should be, initially, the scale-free one, and ii) the memory consolidation should proceed via the building of long-range links that arise at this stage, for instance, by means of new axon-neuron synaptic contacts.
