Times of Change: Overcome Regime Changes in Time-Series Forecasting
Research Team Lead – Pagaya
Ilana is a research team lead at Pagaya, working on forecasting models for the real estate investment domain. Prior to that, she was a team lead developing deep learning models for the financial time series domain. She has many years of experience working at the Sagol Brain Institute (TASMC) as a machine learning algorithm developer in the computational neuroscience field, focusing on challenges in combining fMRI and EEG brain imaging.
Ilana has multiple publications in peer-reviewed journals and is co-author of patents in the field of computational neuroscience. She holds an MSc in biomedical engineering from Tel Aviv University

Accurately forecasting time series data is a critical task in many fields, from finance and economics to engineering and the natural sciences. However, many of these time series are subject to regime changes. Regime changes are changes in the dynamics exhibited by the time series, often driven by external factors. These changes lead to shifts in the series’ statistical properties, which can be difficult to detect and can impact forecasting models’ predictive power.
This talk will discuss different strategies for identifying and adapting to regime changes in time series forecasting, from machine learning algorithms, to identify shifts in regimes, to the incorporation of external domain knowledge indicators as additional input features. This talk will also examine the effectiveness of ensemble techniques for combining multiple models, each trained on a different regime. Case studies from the financial data domain will demonstrate the importance of considering regime changes in time series forecasting and the potential for these techniques to improve accuracy.
