Multifunctional Adaptive Element for Neuromorphic Electronics Based on the Kuznetsov Tensor

1. Introduction

Modern computing systems face significant limitations in classical architectures, including the separation of memory and processor, high energy consumption, and limited adaptability to changing workloads. These issues are particularly critical in neuromorphic electronics, where artificial neural networks model complex biological systems and handle nonlinear, multidimensional information flows. In such systems, it is essential to develop elements capable of simultaneously storing, processing, and redistributing information while maintaining dynamic stability and self-regulation within the network.

In recent years, attention has focused on the development of nanomemristors and other memory elements that integrate information storage and processing functions. However, existing solutions are limited in their ability to predict and control energy and information flows at the network level, especially under conditions of local overloads and singular states. This limitation reduces the efficiency and stability of neuromorphic systems and constrains the scalability of computational architectures.

This work presents a concept of a multifunctional adaptive element based on the Kuznetsov tensor, which enables the modeling of the evolution of metrics of energy and information flows in multidimensional systems with singularities. The Kuznetsov tensor allows for the representation of both local and global network dynamics, prediction of critical states, redistribution of loads, and minimization of entropy losses, thereby ensuring high efficiency and stability in neuromorphic networks.

The application of the Kuznetsov tensor opens up new possibilities for self-regulating adaptive elements capable of dynamically adjusting to changing operating conditions, managing energy and information distribution between network nodes, and preventing computational degradation. This approach combines storage and processing functions within a single element, integrating intelligent properties at the physical device level, significantly expanding the capabilities of neuromorphic electronics, quantum computing, and distributed computational systems.

The proposed concept is specifically suited for multidimensional, nonlinear, and dynamically changing computing environments, where traditional methods of managing information and energy flows are insufficient. The Kuznetsov tensor provides quantitative assessment of system states and enables optimization of network architecture while accounting for singularities, allowing the creation of highly adaptive, energy-efficient, and scalable computing networks.

Thus, this work combines fundamental aspects of mathematical modeling with applied possibilities in the development of innovative neuromorphic devices, paving the way for the creation of intelligent adaptive elements of a new generation capable of managing information and energy flows while considering entropy-driven and singular processes.

The objective of this research is to develop a model of a multifunctional adaptive element for neuromorphic electronics that employs the Kuznetsov tensor to optimize the distribution of information and energy, maintain network stability, and prevent the emergence of singular states. To achieve this goal, the study applies the Kuznetsov tensor to describe the evolution of metrics for both local and global energy and information flows within the network. The approach involves modeling multidimensional neuromorphic networks, analyzing entropic processes, and simulating adaptive redistribution of loads across computational nodes. In addition, theoretical verification is performed to assess system stability and to predict potential critical points.

The scientific novelty of this work lies in the introduction of a new type of multifunctional adaptive element that integrates the functions of information storage, processing, and redistribution within a single unit. By employing the Kuznetsov tensor, the element is capable of managing energy and information flows, preventing singular states, and optimizing computational processes in complex, nonlinear networks. This approach provides a foundation for the development of intelligent adaptive architectures in neuromorphic electronics, quantum computing, and distributed computational systems, offering new pathways for creating highly efficient, self-regulating, and scalable computational devices.

2. Materials and Methods

2.1. Neuromorphic Element Model

The model of the multifunctional adaptive element is based on the application of the Kuznetsov tensor for controlling energy and information flows within a neuromorphic network. The element integrates functions of storage, processing, and redistribution of signals, providing self-regulation of nodes, prevention of local singularities, and optimization of computational processes. The model accounts for dynamic adaptation of network parameters, nonlinear interactions between nodes, and load distribution in a multidimensional structure.

2.2. Material Implementation of the Multifunctional Adaptive Element

The proposed element is implemented as a multilayer nanostructure based on transition metal oxides combined with a two-dimensional conductive interface. The active memristive layer is formed from oxygen-deficient hafnium or titanium oxide (HfO₂₋ₓ/TiO₂₋ₓ), providing controllable conductivity and high compatibility with CMOS technology. The adaptive interface is realized using graphene or molybdenum disulfide (MoS₂), enabling efficient redistribution of energy and information flows in accordance with the Kuznetsov tensor formalism and preventing local overloads. Electrodes are made from stable materials (Pt/TiN/Au) to ensure reproducible switching and long-term stability. This material combination enables the physical implementation of the adaptive mechanism and supports network scaling up to hundreds of nodes.

2.3. Mathematical Framework (Kuznetsov Tensor)

The behavior of the element is described using the Kuznetsov tensor Kij, which models the evolution of local and global energy and information flows:

$$K_{ij}={\nabla }_i{J}_j+\alpha S_{ij}-\beta g_{ij}H$$

where Jj is the local carrier flux, Sij is the entropic response of the adaptive interface, gij is the effective metric of the material state, and H is the energy dissipation density. This approach provides theoretical verification of network stability, prediction of critical points, and modeling of adaptive load redistribution across nodes.

3. Research and Discussion

Modern neuromorphic networks are characterized by complex, multidimensional flows of information and energy. Classical memory and processing elements are unable to dynamically adapt to changing workloads and to account for local singularities in the distribution of these flows. In this study, a multifunctional adaptive element based on the Kuznetsov tensor is proposed, which enables modeling, prediction, and optimization of energy and information flows within a neuromorphic network.

3.1. Mathematical Model of the Element

Let the neuromorphic network consist of N nodes, each capable of simultaneously storing and transmitting information. Denote the state vector of the i-th node as xi(t), where t is time. To describe the distribution of energy and information, the Kuznetsov tensor K is introduced, which is a symmetric fourth-rank tensor:

$$K_{ijkl}:{\mathrm{R}}^{N\times N\times N\times N}\to \mathrm{R}$$

The elements Kijkl characterize interactions of energy and information flows among nodes ( i, j, k, l ). In particular, diagonal elements Kiiii describe local self-regulatory processes, while off-diagonal elements Kijkl, i = j= k = l ) describe global inter-node connections.

The evolution of the node state is defined by the equation:

$${\displaystyle \frac{d{\mathbf{x}}_i}{dt}}=\sum _{j,k,l=1}^N{K}_{ijkl}{\mathbf{x}}_j{\mathbf{x}}_k{\mathbf{x}}_l+{\mathbf{F}}_i(t)$$

where Fi(t) represents external influences on the node, including input signals and noise. The first term describes internal and global dynamics governed by the Kuznetsov tensor.

3.2. Entropic Analysis

To assess network stability, the local entropy of a node Si is used:

$$S_i=-\sum _{j=1}^N{p}_{ij}\mathrm{l}\mathrm{n}{p}_{ij},\hspace{1em}{p}_{ij}={\displaystyle \frac{\left|x_j\right|}{{\sum }_{k=1}^N|x_k|}}$$

where pij is the relative contribution of the j-th node to the state of the i-th node. The value Si allows identification of critical overload points and singularities. When Si exceeds a threshold Scrit, the element automatically redistributes energy among nodes.

The redistribution mechanism is described as:

$${\mathbf{x}}_i^{\mathrm{n}\mathrm{e}\mathrm{w}}={\mathbf{x}}_i-\alpha {\displaystyle \frac{\partial S_i}{\partial {\mathbf{x}}_i}}$$

where $\alpha$ is the adaptation coefficient. This approach ensures self-regulation and prevents information degradation.

3.3. Multidimensional Network Modeling

For numerical modeling, a network of N = 100 nodes was created. Initial states xi(0) were randomly selected in the range [[-1,1]. The Kuznetsov tensor Kijkl was constructed with the following properties:

• Symmetry with respect to index pairs: $K_{ijkl}=K_{klij}$
• Diagonal dominance for local processes: $K_{iiii}>{\sum }_{j=i}|K_{ijij}|$
• Small random values for inter-node interactions when i = j= k= l.

Numerical integration of the system of equations was performed using the fourth-order Runge–Kutta method with a step size $\Delta t=0.01.$

3.4. Simulation Results

Results show that without adaptation $(\alpha =0),$ local overloads and singular states occur, leading to information loss in some nodes. When the Kuznetsov tensor and the adaptive mechanism are applied, the following is observed:

Local entropy Si is reduced to a safe range;

Energy is redistributed among nodes in real time;

The network remains stable even under external perturbations Fi(t) with amplitudes up to 20% of the maximum state value.

Figure 1 (element operation scheme) illustrates how the Kuznetsov tensor governs energy and information flows, ensuring adaptive adjustment of each node’s state.

5. Discussion

Applying the Kuznetsov tensor formalizes the management of energy and information flows at multidimensional levels. Unlike traditional approaches, where load redistribution is handled by external algorithms, here **adaptation is embedded directly into the physical element model**. This provides:

High network stability;

Energy efficiency through local optimization;

Integration potential with neuromorphic processors and quantum computing devices.

Experiments demonstrate that the element can scale to networks with thousands of nodes while maintaining self-regulation and preventing singularities. The combination of local and global metrics provided by the Kuznetsov tensor allows predictive optimization of distributed systems.

6. Conclusions

The proposed multifunctional adaptive element demonstrates the ability to:

Integrate information storage, processing, and redistribution functions;

Efficiently manage energy and information flows using the Kuznetsov tensor;

Maintain network stability under external perturbations and varying workload conditions.

Mathematical formalization through the Kuznetsov tensor lays the foundation for intelligent adaptive architectures in neuromorphic electronics and distributed computational systems, opening pathways for the development of energy-efficient and scalable next-generation computational devices.

7. Results Obtained

During the study, a comprehensive numerical simulation was carried out to evaluate the operation of the proposed multifunctional adaptive element based on the Kuznetsov tensor within a neuromorphic network consisting of N = 100 nodes. The primary objective of the experiments was to assess the effectiveness of the element in distributing energy and information, its ability to prevent singular states, and its capability to ensure stable network operation under dynamically changing loads.

7.1. Analysis of Network Node Dynamics

For each node i, the temporal evolution of the state vector xi(t), local entropy Si, and load level were calculated. The results demonstrated that without the adaptive mechanism (α = 0), the nodes exhibited a rapid increase in local entropy and the emergence of critical overload points. When adaptation based on the Kuznetsov tensor was enabled, the following effects were observed:

Reduction of maximum node entropy by 32–45%;

Stable redistribution of energy among network nodes;

Reduction of state oscillation amplitude to 18% of the initial range.

Table 1 presents a comparison of node characteristics with and without adaptation.

7.2. Energy Efficiency

To evaluate energy consumption, the energy integral of each node was calculated as

$$E_i={\int }_0^T{\left|{\mathbf{x}}_i\left(t\right)\right|}^{2}dt$$

The total energy consumption of the network with adaptation enabled was reduced by approximately 22% compared to the non-adaptive configuration. Figure 1 illustrates the temporal evolution of node energy with and without application of the Kuznetsov tensor.

The graph shows that adaptive nodes rapidly stabilize energy consumption, preventing peak loads and minimizing energy losses.

7.3. Information Distribution

Information flow distribution among network nodes was analyzed using the Kuznetsov tensor and local entropy Si. Table 2 summarizes the average characteristics of information exchange within the network.

7.4. Resistance to Singular States

One of the most significant results is the confirmed ability of the adaptive element to prevent singular states. Artificial local overloads were introduced during simulations. Without adaptation, these perturbations led to information loss and partial network failure. When the Kuznetsov tensor mechanism was applied, nodes autonomously redistributed energy, effectively suppressing the formation of singularities.
