报告摘要:

In recent years, deep learning (DL) has significantly penetrated and has been widely adopted in various fields of application, including facial recognition, strategy games (AlphaGo and Texas hold'em) and question answering. However, the effectiveness of the models and efficiency of the training process strongly depend on how well the associated data is managed. It is very challenging to train an effective deep learning-based image classifier without properly labelled training data. Furthermore, training efficiency is severely affected by a large amount of training data, complex structures of the models and tones of hyper parameters. A lack of validation for result data and explanation also seriously affect the applicability of trained models. In this talk, I will discuss three important issues related to data science for AI: 1) how to prepare data for effective DL, which includes data extraction and integration as well as data labelling; 2) how to optimize DL training, including data compression and computation graph optimization; and 3) how to conduct explanation to make the model robust and transparent. Some future work will be highlighted at the end. At then enf of my talk, I will give a brief introduction of Data Science and Analytic Program in HKUST (GZ) and Postgraduate recruitment information of the DSA program.
