Top /r/MachineLearning Posts, Feb 1521: The Elephant in the Room of ML Research
Tags: Coursera, Deep Learning, Genetic, Graph Visualization, Network Graph, Overfitting, Python, Reddit
Problems with deep learning papers, Coursera linear algebra courses, Reddit comment visualizations, deep learning lectures, and genetic algorithm introductions make up the top posts this week on /r/MachineLearning.
By Grant Marshall.
This week on /r/MachineLearning, we see a discussion of the current state of ML research, a new linear algebra course, a network analysis of Reddit comments, a handson introduction to deep learning, and a basic introduction to genetic algorithms.
1. [Discuss] The elephant in the room of machine learning research +148
This selfpost (textonly post) decries the use of hyperparameter tweaking as a justification for publishing entire papers. The author sees these papers, which they claim are becoming more common, as being misleading and unnecessary. It seems that many in the /r/MachineLearning community agree, based on the fact that this is so highlyupvoted. There is some interesting discussion in the comments.
2. Coursera Free course on Linear Algebra. Coding The Matrix: Linear Algebra Through Computer Science Applications by Philip Klein +97
This new Coursera course covers basic linear algebra. More importantly, it does so through applications. So if you need to learn basic linear algebra and you find an applicationbased method best for you, give this one a shot.
3. What interests Reddit? A network analysis of 84M comments by 200K users +94
This post analyzes the network of Reddit comments over a large dataset. The included visualization is wellmade (and very complex), but I fear that complexity makes it fairly difficult to draw general conclusions about the network and Reddit itself. Regardless, the author has some interesting thoughts about apparent patterns in the data, and it’s worth looking at.
4. Introduction to Deep Learning with Python  [52:41] +74
This stepbystep video explains why you may want to use deep learning, then dives into using deep learning using Python. It’s fairly indepth for an introduction to the topic, so if you’ve been waiting for a good handson way to get into deep learning, this may be the way to do it.
5. The Genetic Algorithm  Explained +66
This article is a great firstexposure to the topic of genetic algorithms. It goes through the structure and motivation for using genetic algorithms. It then details some pseudocode and explains various properties of genetic algorithms through some examples.
