报告摘要: Machine Learning (ML) has been around for decades, empowering many AI applications from computer vision, to bioinformatics. Recently Deep Learning gained a remarkable popularity as a branch of ML, by its power to progressively extract higher-level features from the raw input through multiple "deep" layers. Convolutional Neural Network (CNN) is such a flagship model of DL that has unprecedented influential innovations in the field of computer vision and object recognition. While CNN has shown its power in many real-life case studies and successful deployment, recently much attentions of computer scientists are focused on how to build a best CNN for a given task with the best performance. In this workshop, we would introduce about a holistic methodology called Optimized Learning (OL) which is designed to uplift the performance of DL, from augmenting the input data, to the CNN optimization and corrective output learning. The context of optimization in OL here is different from traditional optimization algorithms. ML usually acts indirectly in terms of enhancing the prediction performance. The speaker shares with his two decades of data mining experience from which, it is observed that optimization in OL needs to be done at several levels and at different places of a ML model. This talk sheds light to anybody who is interested in leveraging a better ML/DL model for better outcomes, especially in critical applications where the best possible accuracy matters.
