Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Transformer and Mamba frameworks face challenges with quadratic computational complexity, increased learning parameters, and training instability when handling long input sequences, leading to high latency and performance gaps compared to state-of-the-art models.
Innovation Solution
The introduction of a gated spectral state space model (GSSSM) that performs spectral transformations of embedded input image patches, eliminates the need for an initial convolutional neural network layer, and uses a parametrized Gaussian function for training, reducing the number of learning parameters and improving training stability.

Engineering Contradiction Analysis
1Reliability
If transformer models are used for processing long sequences, then comprehensive feature representation is achieved, but computational complexity increases quadratically
Solution Approach 1:
The patent transforms the state space model parameters into the spectral domain using Fourier transforms. By operating in the frequency domain rather than the time domain, the computational complexity of the state space model is reduced from quadratic to linear, while maintaining the ability to process long sequences effectively. The spectral parameters capture temporal patterns more efficiently.
Solution Approach 2:
The patent replaces the traditional mechanical sequential processing of transformer attention mechanisms with a spectral transformation approach. Instead of computing pairwise attention scores between all sequence elements (O(n²) complexity), the system uses Fourier transforms to globally capture temporal patterns in O(n log n) complexity, substituting the mechanical attention computation with a more efficient spectral analysis.
2Productivity
If Mamba frameworks are applied to vision tasks, then sequence processing efficiency is improved, but training stability deteriorates
Solution Approach 1:
The patent applies spectral transformation to the state space model parameters, changing their representation from the time domain to the frequency domain. This parameter transformation stabilizes training by decoupling the temporal dynamics into independent frequency components, making the optimization landscape more favorable and reducing training instability issues observed in conventional Mamba frameworks.
3Ease of manufacture
If conventional architectures are used, then implementation simplicity is maintained, but performance in long sequence tasks deteriorates
Solution Approach 1:
The patent creates a universal gated spectral state space model that can handle both vision and language tasks. The spectral SSM architecture serves multiple functions: it processes long sequences efficiently, maintains training stability, and can be applied to various modalities (images, text). This multi-functional design achieves state-of-the-art performance across different tasks while maintaining relative implementation simplicity through the unified spectral transformation approach.

AI summary
A system may generate embedded subsets by projecting each subset of the subsets into a vector space to generate a corresponding embedded subset. A system may encode the embedded subsets into an encoded image using a dataset encoder including a gated spectral state space model, the gated spectral state space model being a gated neural network that includes a spectral state space model, the spectral state space model being a state space model that represents features of the input dataset using at least a spectral transformation of each embedded subset of the embedded subsets. A system may predict a classification for the input dataset using the encoded image.
