Robust topological grammars for unsupervised neural networks

We develop a family of robust algorithms for unsupervised learning. These algorithms aim to assimilate datasets of complex topologies and to approximate data by dendrite and cubic complexes. We develop the measure of the approximator complexity and find the balance between accuracy and complexity and to define the optimal approximations.

The cochlea – a prototypical ancient neural network with a critical architecture

Using a biophysically close implementation of the mammalian hearing sensor, we have recently shown that the pitch we perceive for complex sounds is of purely physical, in contrast to a cortical, origin. From the physical principles that guidelined the evolution of our hearing sensor, we infer the nature of pitch as the embracing description the emergent complexity from the interaction of the nonlinear amplifiers present in the sensor, and use it to purposefully to tune the sensor towards the perception of sounds we want to listen to. We then show that the network of the amplifiers resident in the hearing sensor is critical, and observe how this changes, as we listen to a target sound.

Understanding the capacity of information retrieval from long-term memory

Human memory stores vast amounts of information. Yet retrieving this information is challenging when specific cues are lacking. Classical experiments on free recall of lists of randomly assembled words indicate non-trivial scaling laws for the number of recalled words for lists of increasing length. The fundamental factors that control retrieval capacity are not clear. Here we propose a simple associative model of retrieval where each recalled item triggers the recall of the next item based on the similarity between their long-term neuronal representations. The model predicts retrieval capacity laws that are compatible with the psychological literature.

Dendrites, neurons and resonances

Gap junctions, also referred to as electrical synapses, are expressed along the entire central nervous system and are important in mediating various brain rhythms in both normal and pathological states. These connections can form between the dendritic trees of individual cells. To obtain insight into the modulatory role of gap junctions in tuning networks of resonant dendritic trees, I will present two methods for calculating the response function of a network of gap-junction coupled neurons. These methods will then be used to construct compact closed form solutions for a two-cell network of spatially extended neurons which will allow the study of the role of location and strength of the gap junction on network dynamics.

The cognitome: a hypernetwork brain model

Despite impressive advances in neuroscience, the nature of the higher brain functions still eludes satisfactory understanding. This situation, known as «explanatory gap», calls for new explanatory models and principles. This report will suggest a model of the brain as the cognitive hypernetwork – K-network. The vertices of the K-network (cognitome) are COGs (GOgnitive Groups) - subsets of vertices from the underlying N-network (connectome) associated by a common cognitive experience. Edges between k-vertices in the cognitome are formed by the sum of edges between subsets of corresponding n-vertices in connectome. In terms of algebraic topology COG is a relational simplex or hypersimplex. Its base is the simplex from vertices of the underlying N-network and its apex is the vertex possessing a new quality at the higher-level K-network. Hypernetworks generalize networks and hypergraphs, provide formalism for description of emergent phenomena in the multi-level systems, and allow modeling much more complex structures than networks and hypergraphs. The report presents some non-trivial bipartite relations between N- and K-networks that form a background for the hypernetwork brain theory (HNBT).

Functional capabilities of biologically inspired cognitive architectures

General functional aspects of human cognition can be described at a computational level and replicated in a machine based on principles that do not require detailed modeling of neurons and brain structures. These are, primarily, basic principles of perception, reasoning, decision making and action control, formulated in terms of symbolic models like cognitive architectures. The key principles are those that support social-emotional intelligence, narrative intelligence, metareasoning, autonomous goal reasoning, semantic mapping, human-level teachability and creativity. Creation of a machine analog of the human mind based on these principles and its acceptance as a human-equivalent character will lead to a technological breakthrough with an impact on all aspects of human life.

Neurophysiological and psychological foundation of the symbolic picture of the world

A model of the world picture of the active subject is considered. The model is based on data of neurophysiological studies and on the well-known psychological phenomena. The processes of the formation of patterns, patters significance and personal meaning as well as the operations of generalization, agglutination, and introspection are considered. Models of such functions of consciousness as goal setting and synthesis of behavior are designed. The existence of different types of world pictures generated by active subjects is explained.
