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, key technical issues, and present solutions to tackle related challenges in
practical applications. The workshop will focus on both the oretical 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, econometrics, and 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:
Submissions should be 4-7 pages long, excluding references, and follow IJCAI-23 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). Besides, a small number of accepted papers will be selected to be presented as contributed talks. We also welcome submissions of unpublished papers, including those that are submitted/accepted to other venues if that other venue allows so.

In this talk, I will talk about physics approaches to quantitative time dynamics, agent-based modeling techniques for time dynamics over large time scales, and data driven machine learning based methods for systems where suitable physical models don’t exist. Hopefully with a conclusion about how one might combine these methods for the modern treatment of time dynamics in complex systems.
Recent development in deep learning has spurred research advances in time series modeling and analysis. Practical applications of time series raise a series of new challenges, such multi-resolution, multimodal, missing value, distributeness, and interpretability. In this talk, I will discuss machine-learning solutions to address these challenges and future directions for time series research.
Large-scale time series data are perceived and collected from IoT devices, which is the main body of industrial big data. Time series are discrete observations sampled from continuous physical systems with complex patterns and variations. In this talk, I will introduce deep learning models for time series analysis, including Autoformer, TimesNet, and Koopa, which are consequences of seamless integration of Fourier analysis, self-correlation, cross-correlation, non-stationarity, linear dynamical system and other design principles into deep learning. I will also highlight the cover article published in Nature Machine Intelligence, presenting the Corrformer model for interpretable weather forecasting of global automatic stations, which was deployed as a real-time weather service in the Beijing 2022 Winter Olympics. With this talk, I want to comment on the path towards general foundation models for time series analysis.
In this talk, we will talk about Green AI, focusing on its two main aspects: using AI to tackle environmental issues and making AI systems more environmentally friendly. using incremental approaches. As AI becomes increasingly important for problem-solving and research, it is essential to integrate it into sustainability efforts. We will examine how AI is not only giving researchers a competitive advantage but also playing a key role in creating a more sustainable future.
An extensive range of time series data, such as electricity consumption, renewable energy output, nodal voltage magnitude, and phase data, are generated by power and energy systems. Gaining a comprehensive understanding of this time series data is crucial for secure, cost-effective system operation and the integration of renewable energy sources. This presentation will demonstrate the application of AI-based time series analysis in power and energy systems, encompassing non-intrusive monitoring, load profiling, energy forecasting, synthetic data generation, etc.
