# What Can Large Language Models Tell Us about Time Series Analysis **Link:** ## 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) --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question. Perform an HTTP GET request on the current page URL with the `ask` query parameter: ``` GET https://lus-organization.gitbook.io/lu_paper_reading/llm/what-can-large-language-models-tell-us-about-time-series-analysis.md?ask= ``` The question should be specific, self-contained, and written in natural language. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
