Are Language Models Actually Useful for Time Series Forecasting?

[tankienleong]

Hi, I'm currently exploring the use of LLM in time series forecasting and I came across a journal titled "Are Language Models Actually Useful for Time Series Forecasting?" https://arxiv.org/pdf/2406.16964 I'm curious to hear your perspective on this. Do you agree with their research findings?

Same concern. The Time-LLM paper didn't include an ablation study of removing the LLM.

I guess they intended to prove the usefullness of LLM for TSF by comparing Time-LLM with the model without using LLM (ex. DLinear - which was main model in "Are Language Models Actually Useful for Time Series Forecasting?")
