Projects

Recommender Systems

Research on recommender systems forms a core part of our investigative pursuits at DELTA Lab. We delve into an array of study areas within this discipline that encompasses collaborative filtering methodologies, explainability and interpretability for recommender systems, prediction of consumer repurchasing cycles, reinforcement learning strategies, among other intriguing aspects.

eXplainable AI (XAI)

Explainable AI (XAI) bridges the gap between complex machine learning models and human interpretability, ensuring that AI-driven decisions are transparent and understandable. As AI systems become increasingly integrated into critical sectors like healthcare, finance, and law, it's essential for stakeholders to trust and validate the algorithms' outcomes. Moreover, XAI empowers users to identify potential biases, mistakes, or injustices, fostering more ethical, fair, and accountable AI applications.In DELTA Lab we develop novel XAI techniques with SOTA results. 

Inflation Forecasting

Inflation is a key driver of economic policy decisions, and its accurate prediction can greatly influence fiscal stability and market confidence. Traditional economic models, while useful, often struggle to incorporate and process the sheer volume and complexity of data now available. Machine learning, with its ability to discern patterns and relationships in large datasets, holds great promise to enhance the accuracy and reliability of inflation forecasts. By developing new machine learning algorithms tailored for this task, we can potentially unlock deeper insights into economic trends, improve the precision of policy responses, and thereby contribute to sustainable economic growth and stability. This research is a collaboration with the Bank of Israel.

Machine Learning for Agricultural Improvements

We have a strong collaboration with the Volcani Institute Agricultural Research Organization. As part of this collaboration, DELTA Lab helps integrating advanced machine learning technologies for a wide area of agricultural applications ranging from post-harvest quality prediction, hyper-spectral seed scanning, and even maggot farming!

Machine Learning for Electronic Music Production

At DELTA, we are very interested in the problem of sound-matching for real-world synthesizers. Synthesizers are musical instruments that are widely used in electronic music production. Given an input sound, inferring the underlying synthesizer's parameters that will reproduce it is a difficult task known as sound-matching. Our research tackles the problem of automatic sound matching, which is otherwise performed manually by professional audio experts. 

Dr. Noam Koenigstien

Head of DELTA Lab

Dr. Noam Koenigstein's academic journey began at the Technion – Israel Institute of Technology, where he graduated with honors in computer science for his B.Sc. degree. He furthered his education at Tel-Aviv University, earning a M.Sc. degree in Electrical Engineering, and subsequently, a Ph.D. from the same school focused on machine learning algorithms for recommender systems. In 2011, Dr. Koenigstein entered the industry as a member of Microsoft's Xbox Machine Learning research team, developing the algorithm for Xbox recommendations that reached millions of users globally. His trajectory within Microsoft culminated in him leading the recommendations research team for Microsoft’s Store. In 2017, he embarked on a new role as Senior VP Head of Data Science at Citi bank’s Israeli Innovation Lab, responsible for supervising all data science initiatives in the Israeli research center. In 2018, he transitioned back to academia, joining the Industrial Engineering department of Tel-Aviv University as a Senior Lecturer (Assistant Professor). Currently, he is the director of the DEep Learning Technologies and Applications (DELTA) Lab at Tel-Aviv University's Department for Industrial Engineering. Here, he mentors students in the application of machine learning algorithms to an array of real-world problems.

Dr. Liron Izhaki-Allerhand

Associate Researcher and Advisor 

Dr. Liron Izhaki-Allerhand received his Ph.D. in the Department of Electrical Engineering in Tel Aviv University in 2014. He then assumed leadership roles in various renowned organizations, including a senior researcher at Microsoft. In recent years, he took a leadership role in Hour One, a company specializing in Generative AI, where he’s the Head of AI.
