Linking Fundamental Physics to Deep Learning

Ever since Mehta and Schwab laid out the relationship between restricted Boltzmann machines (RBM) and deep learning mathematically (see my previous entry), scientists have been discussing why deep learning works so well. Recently, Henry Lin and Max Tegmark put a preprint on arXiv (arXiv:1609.09225), arguing that deep learning works because it captures a few essential … More Linking Fundamental Physics to Deep Learning

SOCcer: Computerized Coding In Epidemiology

There are many tasks that involve coding, for example, putting kids into groups according to their age, labeling the webpages about their kinds, or putting students in Hogwarts into four colleges… And researchers or lawyers need to code people, according to their filled-in information, into occupations. Melissa Friesen, an investigator in Division of Cancer Epidemiology … More SOCcer: Computerized Coding In Epidemiology

Law Prediction

On August 1, my friends and I attended a meetup host by DC Data Science, titled “Predicting and Understanding Law with Machine Learning.” The speaker was John Nay, a Ph.D. candidate in Vanderbilt University. He presented his research which is at an application of natural language processing on legal enactment documents. His talk was very … More Law Prediction

Ethics and Political Correctness in Algorithms

Recently I read an article regarding ethics in data science. The ethics here is not about plagiarism, disclosure of confidential data, or dishonesty, but the decision in designing a model with the consideration of ethics. This sparked my thinking without any conclusions. A lot of countries have a long and painful history of racism. In … More Ethics and Political Correctness in Algorithms

Core Competencies of Data Science Education

What should a data scientist know? What are the core skills of a data scientist? I have not seen another job title so vague and ambiguous that arouses so many debates and discussions. BD2K (Big Data to Knowledge) Centers of NIH (National Institutes of Health) [Ohno-Machado 2014] have issued funding to a few tertiary colleges … More Core Competencies of Data Science Education

Talking Not So Deep About Deep Learning

On October 14, 2015, I attended the regular meeting of the DCNLP meetup group, a group on natural language processing (NLP) in Washington, DC area. The talk was titled “Deep Learning for Question Answering“, spoken by Mr.┬áMohit Iyyer, a Ph.D. student in Department of Computer Science, University of Maryland (my alma mater!). He is a … More Talking Not So Deep About Deep Learning
