## Abstract

LLM can get involved in time series analysis.

## LLM Background

```
- Pro: 0 shot 
- Con: Primary for Text sequence
```

Idea: time series and textual information provide essential contexts, LLMs contribute internal knowledge and reasoning capabilities, and pre-trained time series models offer fundamental pattern recognition assurances

Time series data modality:

* Univariate: X = {x1, x2, · · · , xT } ∈ R^T
* Multivariate: X = {x1, x2, · · · , xT } ∈ R^(N\*T)
