    JAAS authorisation issue.

    Posted: 24 Jan 2021 03:05 AM PST

    Anyone familiar with JAAS authorisation and policy files? I have a readFile function that reads from a text file and I set the permission to "read" on the policy file to grant access to principal "testUser". When I run it with security manager I get a "access denied" error. The stack trace includes a line from readFile function: File obj = new File(sample.txt). Any ideas? :)

    [TechBlog] Synced Tradition and Machine Learning Series | Part 2: Optimization Basics

    Posted: 23 Jan 2021 06:51 AM PST

    This is the second in a special Synced series of introductory articles on traditionally theoretical fields of studies and their impact on modern-day machine learning. Part 1: Entropy is here.

    The purpose of this article is to provide a comprehensive account of mathematical optimization and some applications in machine learning at the introductory level. We will go over the basics of optimization and discuss some of the core concepts of optimization algorithms. We will also introduce a number of important descent algorithms, such as steepest descent, Newton's method and variations on these two. In addition, we will extend these ideas to neural network training to provide further insight on these classic topics and their influence in machine learning.
