Small Models for Big Data

Many complex machine learning models such as deep neural networks have demonstrated tremendous success for big data. However, these advances are not necessarily feasible when deploying these models to devices due to large model size and evaluation cost. In many real-world applications such as robotics, self-driving car and smartphone apps, the learning tasks need to be carried out in a timely fashion on a computation and memory limited platform. Therefore, it is extremely important to study building “small” models from “big” machine learning models trained on big data. The main topic of my research is to investigate how to reduce the model size and speed up the elevation for complex machine learning models while maintaining similar accuracy. Specifically, I will discuss how to compress the model for different real world machine learning applications, including extreme multi-label learning and classification.
