FoodAI uses state of the art visual recognition technology, based on Deep Learning, to enable smart food recognition. It is designed to recognize over 750 commonly found food categories in Singapore. This technology is currently in use by several organisations globally.

AntiMalweb investigates machine learning techniques for Malicious URL Detection. Traditional approaches rely on blacklists, which can not be exhaustive, and are not useful for newly generated URLs. Using machine learning solutions, thus, offers a promising direction to solve this problem.

LIBOL is a Library of Online Learning algorithms, a class of machine learning algorithms that learn from a stream of data where instances arrive sequentially. The on-the-fly nature of these algorithms makes them extremely scalable.

Online Portfolio Selection deals with application of online learning to determine the wealth allocation into a portfolio of assets with the goal to optimize a certain metric (e.g. cumulative wealth, risk-adjusted return, etc.)
