2021 marks the second year of The Innovation Sandbox portal since it was launched and will see several new and continued projects taking place with new students and new partnerships. The Innovation Sandbox is a collaborative initiative at the confluence of industry-academia, allowing both academic types of research on real-world datasets and the transfer of cutting-edge machine learning research into industry application In this episode, we will hear our scientists discuss their new project on the application of machine learning and natural language processing (NLP) fro a leading e-commerce platform. They will guide us through challenges, goals and future implications of the projects as well as their time scale and next steps.
