Submitted Apr 13, 2017 (Edited Apr 13, 2017) to Science Books These notes are an attempt to extract essential machine learning concepts for beginners. They are a draft and will be updated. Likely they won’t be typos free for a while. They are dry and lack examples to complement and illustrate the general ideas. Notably, they also lack references, that will (hopefully) be added soon. The mathematical appendix is due to Andre Wibisono’s notes for the math camp of the 9.520 course at MIT.

Submitted Apr 13, 2017 to Science Courses and Tutorials The course covers foundations and recent advances of Machine Learning from the point of view of Statistical Learning and Regularization Theory. The goal of this course is to provide students with the theoretical knowledge and the basic intuitions needed to use and develop effective machine learning solutions to challenging problems.

Submitted Mar 31, 2017 to Science Courses and Tutorials In the last few years, new inference methods have allowed big advances in probabilistic generative models. These models let us generate novel images and text, find meaningful latent representations of data, take advantage of large unlabeled datasets, and even let us do analogical reasoning automatically. This course will tour recent innovations in inference methods such as recognition networks, blackbox stochastic variational inference, and adversarial autoencoders. It will also cover recent advances in generative model design, such as deconvolutional image models, thought vectors, and recurrent variational autoencoders. The class will have a major project component.

Submitted Mar 24, 2017 to Science Blogs tSNE is the very popular algorithm to extremely reduce the dimensionality of your data in order to visually present it. It is capable of mapping hundreds of dimensions to just 2 while preserving important data relationships, that is, when closer samples in the original space are closer in the reduced space. tSNE works quite well for small and moderately sized realworld datasets and does not require much tuning of its hyperparameters. In other words, if you’ve got less than 100,000 points, you will apply that magic black box thing and get a beautiful scatter plot in return.

Submitted Mar 13, 2017 to Science Blogs Given all the hype and buzz around machine learning and IoT, it can be difficult to cut through the noise and understand where the actual value lies. In this week’s #askIoT post, I’ll explain how machine learning can be valuable for IoT, when it’s appropriate to use, and some applications and use cases currently out in the world today.

Submitted Mar 09, 2017 to Science Research Groups » Computer Science The Mizar project started around 1973 as an attempt to reconstruct mathematical vernacular in a computeroriented environment.
Since 1989, the most important activity in the Mizar project, apart from continual improvement of the Mizar System, has been the development of a database for mathematics. International cooperation (the main partners: Shinshu University in Nagano and University of Alberta in Edmonton) resulted in creating a database which includes more than 9400 definitions of mathematical concepts and more than 49000 theorems (see Megrez MML Browsing for more statistics). 
Submitted Mar 08, 2017 to Science Blogs The joint manytask model tackles multiple NLP tasks with a single architecture.

Submitted Mar 03, 2017 (Edited Mar 03, 2017) to Scientific Software Edward is a Python library for probabilistic modeling, inference, and criticism. It is a testbed for fast experimentation and research with probabilistic models, ranging from classical hierarchical models on small data sets to complex deep probabilistic models on large data sets. Edward fuses three fields: Bayesian statistics and machine learning, deep learning, and probabilistic programming.
Edward is built on top of TensorFlow. It enables features such as computational graphs, distributed training, CPU/GPU integration, automatic differentiation, and visualization with TensorBoard. 
Submitted Mar 02, 2017 to Scientific Software Mathematical optimization is a wellstudied language of expressing solutions to many reallife problems that come up in machine learning and many other fields such as mechanics, economics, EE, operations research, control engineering, geophysics, and molecular modeling. As we build our machine learning systems to interact with real data from these fields, we often cannot (but sometimes can) simply ``learn away'' the optimization subproblems by adding more layers in our network. Welldefined optimization problems may be added if you have a thorough understanding of your feature space, but oftentimes we don't have this understanding and resort to automatic feature learning for our tasks.
Until this repository, no modern deep learning library has provided a way of adding a learnable optimization layer (other than simply unrolling an optimization procedure, which is inefficient and inexact) into our model formulation that we can quickly try to see if it's a nice way of expressing our data. See our paper OptNet: Differentiable Optimization as a Layer in Neural Networks and code at locuslab/optnet if you are interested in learning more about our initial exploration in this space of automatically learning quadratic program layers for signal denoising and sudoku. 
Submitted Mar 01, 2017 to Scientific Software Scikitplot is an intuitive library to add plotting functionality to scikitlearn objects.
Scikitplot is the result of an unartistic data scientist's dreadful realization that visualization is one of the most crucial components in the data science process, not just a mere afterthought. Gaining insights is simply a lot easier when you're looking at a colored heatmap of a confusion matrix complete with class labels rather than a singleline dump of numbers enclosed in brackets. Besides, if you ever need to present your results to someone (virtually any time anybody hires you to do data science), you show them visualizations, not a bunch of numbers in Excel. That said, there are a number of visualizations that frequently pop up in machine learning. Scikitplot is a humble attempt to provide aestheticallychallenged programmers (such as myself) the opportunity to generate quick and beautiful graphs and plots with as little boilerplate as possible.
