Spectral Memory: Enhancing Forecasting Accuracy
Read Full Article: Spectral Memory: Enhancing Forecasting Accuracy
Spectral Memory introduces a novel mechanism that captures the hidden-state evolution across training mini-batches to encode temporal structures not available in individual sequences. By utilizing Karhunen–Loève decomposition, it extracts dominant modes and projects them into Spectral Memory Tokens, which provide global context and act as a structural regularizer for stabilizing long-range forecasting. This approach demonstrates competitive performance in time-series forecasting tasks, achieving low mean squared error (MSE) on datasets like ETTh1 and Exchange-Rate, and is designed to be easily integrated into existing systems. This matters because it offers an innovative way to enhance the accuracy and stability of predictive models by leveraging the training trajectory itself as a source of information.

LLM Identity & Memory: A State Machine Approach
Read Full Article: LLM Identity & Memory: A State Machine Approach
The current approach to large language models (LLMs) often anthropomorphizes them, treating them like digital friends, which leads to misunderstandings and disappointment when they don't behave as expected. A more effective framework is to view LLMs as state machines, focusing on their engineering aspects rather than social simulation. This involves understanding the components such as the Substrate (the neural network), Anchor (the system prompt), and Peripherals (input/output systems) that work together to process information and execute commands. By adopting this modular and technical perspective, users can better manage and utilize LLMs as reliable tools rather than unpredictable companions. This matters because it shifts the focus from emotional interaction to practical application, enhancing the reliability and efficiency of LLMs in various tasks.
