With the advent of Big Data, we can learn more about our clients, and we can create 360-degree views which help better understand their needs and their pain points. In this talk, I will describe the building of a business-to-business (B2B) recommendation engine that predicts the interest of clients in products using both proprietary and public data sources. For such a system, interpretability of the predicted action is particularly important, because generated recommendations will be furnished to the salesperson responsible for the client account. We address interpretability by transforming the recommendation problem into an instance of an overlapping co-clustering problem. With the use of GPUs, we can also significantly reduce the training of the recommendation engine from hours to only a few seconds, converting time-consuming analytics processes into totally interactive sessions for the Data Scientists. Finally, I will present how the results of the recommendation engine can be coupled with a Natural Language interface to provide an easy-to-use search platform.
