Recommender and Search Ranking Systems in Large Scale Real World Applications

Recommendation and search systems are two of the key applications of machine learning models in industry. Current state of the art approaches have evolved from tree based ensembles models to large deep learning models within the last few years. This brings several modeling, systems, infrastructural and software challenges and improvements with it. Additionally, Large Language Models and Foundation Models are also rapidly starting to influence the capabilities of these real world search and recommender systems.

In this talk, Moumita will present an overview of industry search and recommendations systems, go into modeling choices, data requirements and infrastructural requirements, while highlighting  challenges typically faced for each and ways to overcome them.

Why Most Machine Learning Projects Fail to Reach Production and How to Beat the Odds

Despite the hype around AI, many ML projects fail, with only 15% of businesses' ML projects succeeding, according to McKinsey. Particularly with the significant investments in large language models and generative AI, only a small portion of companies have managed to realize their true value.
