The deep learning revolution began with the winning of the ImageNet 2012 challenge by a convolutional neural network AlexNet, and then PyTorch, an open-source framework, has facilitated model innovations, further advancing the field. Recently, data has become increasingly important in AI, leading to the emergence of data-centric AI. In this talk, I will share my experience working with the ImageNet-21K dataset, which is a much larger version of the static ImageNet-1K dataset, and how I leveraged the interplay between machine learning, signal processing, and computing to achieve further progress.

As the creator of open-source projects FinRL, ElegantRL, and FinGPT, I will discuss my experiences using these tools to tackle the challenging domain of the financial market. Financial reinforcement learning presents unique challenges due to the highly dynamic nature of financial data. FinRL and FinGPT build upon the success of deep learning, and I will focus mainly on an automatic data curation pipeline that addresses the challenges of handling financial data.

This seminar will be held both online & in person. You are welcome to join us either in South Hall or via Zoom.
