In this blog, lets talk about multi target variables. In a generic machine learning model prediction scenario, where we will have input features and single target variable. Input Feature Output Feature x1 , x2 , x3 , x4… y Assigning multiple target variables would throw an error on line... Read more 26 Dec 2018 - 3 minute read
Let’s cover the fundamentals. What is Convolution? Convolution uses kernels/filter to extract information from images. Different kernels can extract different representations from images. For different tasks such as sharpening , edge detection , blurring different kernels can be employed. Kernel is matrix which slides upon the image to extrac... Read more 12 Dec 2018 - 3 minute read
SGDR: STOCHASTIC GRADIENT DESCENT WITH WARM RESTARTS Restart techniques are common in gradient-free optimization to deal with multimodal functions. Partial warm restarts are also gaining popularity in gradientbased optimization to improve the rate of convergence in accelerated gradient schemes to deal with ill-conditioned functions. In ...

Gradient Descent Finds Global Minima of Deep Neural Networks Simon S. Du Jason D. Lee Haochuan Li Liwei Wang Xiyu Zhai Abstract Gradient descent finds a global minimum in training deep neural networks despite the objective function being non-convex. The current paper proves gradient descent achieves zero training loss in polyn... Read more 14 Nov 2018 - 7 minute read
MASK R-CNN Facebook AI Research (FAIR) Kaiming He Georgia Gkioxari Piotr Dollar Ross Girshick What does Mask R-CNN do We present a conceptually simple, flexible, and general framework for object instance segmentation. Our approach efficiently detects objects in an image while simultaneously generating a high-quality segmentation... Read more 10 Nov 2018 - 11 minute read
Project Frigatebird. Link Github Code Taking instantaneous decisions during an uncertain situation is near impossible for machines even when considering multi-level observations and their striving ability to learn complex policies. This progress is facilitated by the availability of abundant data, simulators such as games. These projects ... Read more 10 Nov 2018 - 2 minute read
