The model-centric approach relies on human heuristics to develop a computer model to extract features from data. These models were engineered by scientists and then validated via empirical studies. A major shortcoming of the model-centric approach is that unusual circumstances that a model does not take into consideration during its design can render the engineered features less effective.  Contrast to the model-centric approach, which dictates representations independent of data, the data-driven approach learns representations from data.  Example data-driven algorithms are multilayer perceptron (MLP) and convolutional neural network (CNN), which belong to the general category of neural network and deep learning.  In this talk I will first explain why my team at Google in 2006 embarked on the data-drive approach.  In 2008, we funded the ImageNet project at Stanford, and subsequently in 2011 filed two data-driven patents, one on data-driven feature extraction and the other on data-driven object recognition.  We parallelized five widely used machine learning algorithms including SVMs, PFP, LDA, Spectral Clustering, and CNN, and open-sourced all these algorithms.  Recently at HTC, we announced DeepQ Open AI platform, which features these scalable algorithms with enhancements.  In particular, I will explain how we have made configuring a distributed system to run CNN both simple and cost effective.    In 2012, the world was convinced that the data-driven approach to be effective, after Alexnet achieved breakthrough accuracy in the ImageNet Large-Scale Visual Recognition Challenge (ILSVRC) competition.  This talk will walk through subsequent enhancements on Alexnet in three perspectives: representation ability, optimization ability, and generalization ability.  Unfortunately, most applications face the problem of small data. I will share our experiences with transfer learning and GANs, both positive and negative ones. This talk concludes with a list of open research issues. (字串長度:2108)```me_desc---->Edward Chang currently serves as the President of Research and Healthcare (DeepQ) at HTC.
