Curriculum Design Helps Spiking Neural Networks to Classify Time Series

no code implementations26 Dec 2023 Chenxi Sun, Hongyan Li, Moxian Song, Derun Can, Shenda Hong

Spiking Neural Networks (SNNs) have a greater potential for modeling time series data than Artificial Neural Networks (ANNs), due to their inherent neuron dynamics and low energy consumption.

TEST: Text Prototype Aligned Embedding to Activate LLM's Ability for Time Series

1 code implementation16 Aug 2023 Chenxi Sun, Hongyan Li, Yaliang Li, Shenda Hong

Given the lack of data, limited resources, semantic context requirements, and so on, this work focuses on TS-for-LLM, where we aim to activate LLM's ability for TS data by designing a TS embedding method suitable for LLM.
