Deep Learning has become a major breakthrough in Artificial Intelligence in recent years. This talk will include a study on implementing L-BFGS, which is a popular optimization algorithm for parameter estimation in machine learning. The speaker will explain how HPCC systems provides the platform as well as the programming language (ECL) in order to implement a parallelized and distributed version of L-BFGS algorithm which work on Big Data. L-BFGS algorithm can be used in not only implementing deep learning algorithms, but also any other Machine Learning algorithm which needs estimating parameters based on optimizing a cost function, such as SVM, Logistic regression, etc.,. At the end the implementations of Sparse Autoencoder algorithm and Softmax classifier are explained as a demonstration on how to use L-BFGS for parameter estimation in such algorithms.
