AI for Time Series Analysis: Theory, Algorithms, and Applications


at SIAM Data Mining 2025



Time series data are becoming ubiquitous in numerous real-world applications, e.g., IoT devices, healthcare, wearable devices, smart vehicles, financial markets, biological sciences, environmental sciences, etc. Given the availability of massive amounts of data, their complex underlying structures/distributions, together with the high-performance computing platforms, there is a great demand for developing new theories and algorithms to tackle fundamental challenges (e.g., representation, classification, prediction, causal analysis, etc.) in various types of applications. The goal of this workshop is to provide a platform for researchers and AI practitioners from both academia and industry to discuss potential research directions, and key technical issues, and present solutions to tackle related challenges in practical applications. The workshop will focus on both theoretical and practical aspects of time series data analysis and aims to trigger research innovations in theories, algorithms, and applications. We will invite researchers and AI practitioners from the related areas of machine learning, data science, statistics, astronomy, and urban design to many others to contribute to this workshop.

This workshop encourages submissions of innovative solutions for a broad range of time series analysis problems. Topics of interest include but are not limited to the following:

  • Time series forecasting and prediction
  • Spatio-temporal forecasting and prediction
  • Time series anomaly detection and diagnosis
  • Time series change point detection
  • Time series classification and clustering
  • Time series similarity search
  • Time series indexing
  • Time series compression
  • Time series pattern discovery
  • Interpretation and explanation in time series
  • Causal inference in time series
  • Bias and fairness in time series
  • Federated learning and security in time series
  • Benchmarks, experimental evaluation, and comparison for time series analysis tasks
  • Time series applications in various areas: E-commerce, Cloud computing, Transportation, Fintech, Healthcare, Internet of things, Wireless networks, Predictive maintenance, Energy, and Climate, etc.

Call for Papers


Submissions should be 5-9 pages long, excluding references, and follow SDM template. Submissions are single-blind and author identity will be revealed to the reviewers. An optional appendix of arbitrary length is allowed and should be put at the end of the paper (after references).


Accepted papers will be presented as posters during the workshop and list on the website (non-archival/without proceedings). We also welcome submissions of unpublished papers, including those that are submitted/accepted to other venues if that other venue allows so.

AI-Driven Forecasting: Harnessing Social Media for Event and Epidemic Prediction

This talk explores how social media time series can be leveraged for the early warning of societal events using the AI-driven forecasting system EMBERS. By modeling temporal patterns in open-source data, augmented by Dynamic Query Expansion (DQE), EMBERS generates real-time predictions of civil unrest with actionable lead times. I will outline its key components, including time-aware event modeling and retrospective evaluation using metrics such as lead time and precision. Case studies from Latin America illustrate how temporal modeling of social signals can yield proactive insights into complex societal dynamics. The second part of the talk introduces SimNest, a deep learning framework that integrates computational epidemiology with social media for real-time flu surveillance. I will also present a multi-task learning approach for spatiotemporal forecasting across regions, designed to address data sparsity and geographic heterogeneity. Together, these approaches demonstrate how AI can effectively model social media time series to enhance crisis anticipation and response.
