Adaptive Information Routing for Multimodal Time Series Forecasting
Researchers have unveiled Adaptive Information Routing (AIR), a new method for multimodal time series forecasting that uses text data as a controller, not just extra input. AIR lets text guide how time series data is processed, boosting forecasting accuracy by up to 38 percent in financial tasks like predicting exchange rates and oil prices. The framework includes a text-refinement pipeline using large language models and offers new benchmark datasets. AIR works with many neural networks but needs further development.
What it examines
This paper introduces the Adaptive Information Routing (AIR) framework for multimodal time series forecasting. AIR uses text data to guide how time series information is processed, improving predictions by combining structured time series and unstructured text. The approach is tested on financial datasets like exchange rates and crude oil prices.
What it concludes
AIR significantly improves forecasting accuracy by using text to control time series models, outperforming existing methods. Potential applications include finance, economics, and any field needing accurate forecasts from mixed data. Future work may explore using different types of text information and further enhancing multimodal data integration.

Traditional approaches primarily rely on historical time series data to predict the future values. However, in practical scenarios, this is often insufficient for accurate predictions due to the limited information available. To address this challenge, multimodal time series forecasting methods which incorporate additional data modalities, mainly text data, alongside time series data have been explored. In this work, we introduce the Adaptive Information Routing (AIR) framework, a novel approach for multimodal time series forecasting. Unlike existing methods that treat text data on par with time series data as interchangeable auxiliary features for forecasting, AIR leverages text information to dynamically guide the time series model by controlling how and to what extent multivariate time series information should be combined. We also present a text-refinement pipeline that employs a large language model to convert raw text data into a form suitable for multimodal forecasting, and we introduce a benchmark that facilitates multimodal forecasting experiments based on this pipeline. Experiment results with the real world market data such as crude oil price and exchange rates demonstrate that AIR effectively modulates the behavior of the time series model using textual inputs, significantly enhancing forecasting accuracy in various time series forecasting tasks. △ Less
