Solution Overview
Problem
Current generative AI models face challenges such as large size, high computational cost, high power consumption, high infrastructure costs, high memory requirements, and high latency, particularly in the inference phase, and integrating spiking neural networks with large language models is hindered by scalability issues, gradient vanishing, and the need for bio-plausible attention mechanisms.
Innovation Solution
Implementing a spiking neural network (SNN) with dendritic dynamics that modulate neuron outputs using contextual data through somatic and dendritic inputs, incorporating a Leaky Integrate Modulated and Fire (LIMF) neuron model to enhance scalability and efficiency, and integrating dendritic computations for intrinsic attention and Mixture-of-Experts (MoE) architectures.

Engineering Contradiction Analysis
1Adaptability or versatility
If current generative AI models are used, then they can perform complex generative tasks, but they consume high power and have high computational cost
Solution Approach 1:
The patent replaces traditional artificial neural network computations with spiking neural network mechanisms that use event-driven, discrete spike transmissions instead of continuous floating-point operations. This substitution fundamentally changes the computational paradigm from high-power conventional processing to energy-efficient neuromorphic processing, reducing power consumption while maintaining generative capabilities
Solution Approach 2:
The patent changes the data representation parameters from continuous floating-point values to discrete spike timing and frequency encodings. By transforming the parameter space of neural computations, the system achieves energy efficiency while preserving the ability to perform complex generative tasks through temporal coding schemes
2Adaptability or versatility
If current generative AI models are used, then they can process complex data, but they have large size and high memory requirements
Solution Approach 1:
The patent extracts and eliminates redundant computational elements from traditional neural networks by using sparse, event-driven spiking mechanisms. Only necessary computations are performed when spikes occur, removing unnecessary continuous activations and reducing overall model size while maintaining data processing capabilities
Solution Approach 2:
The patent segments the neural network into distinct spiking neuron units with localized dendritic computations. This segmentation allows for more efficient memory utilization where each neuron independently processes information through its dendrites, reducing the need for large centralized memory structures
3Productivity
If current generative AI models are used, then they can perform inference tasks, but they have high latency
Solution Approach 1:
The patent employs periodic spiking patterns and rhythmic activation schemes where neurons fire in coordinated oscillations. This periodic action enables efficient information propagation through the network, reducing inference latency by utilizing temporal patterns rather than sequential layer-by-layer processing
Solution Approach 2:
The patent implements preliminary computations within dendritic structures that prepare and pre-process information before somatic integration. This preliminary action in dendrites allows for faster decision-making and reduces the time required for full inference by pre-computing potential outcomes
4Use of energy by moving object
If spiking neural networks are integrated with large language models, then energy efficiency improves, but scalability issues arise
Solution Approach 1:
The patent introduces temporal dimensionality to the spiking neural network architecture, where information is encoded in spike timing and sequences rather than just spatial connections. This additional temporal dimension enables scalable processing by distributing computations across time, allowing the network to handle larger problems without proportionally increasing spatial complexity

AI summary
There is provided an improved neuron model for spiking neural networks. The neuron model comprises somatic synapses as well as dendritic synapses. The somatic synapses are used for receiving an input token, and the dendritic synapses are used for receiving contextual data. The contextual data is used to modulate the behavior of the spiking neuron. The neuron model may be used to implement an attention mechanism in SSNs and to implement a Mixture-of-Experts architecture.
