Starting up with Non - Linear methods

When you are starting up with Non Linear methods , you need to understand how these algorithms approach the problem. The idea is that a non linear problem can be converted to a linear problem by doing some manipulations. One of them could be to just treat it as a linear problem and get an approximate solution. This surprisingly works in most...

Why do you need a Fully Connected Layer?

        A Fully connected layer is the actual component that does the discriminative learning in a Deep Neural Network. It’s a simple Multi layer perceptron that can learn weights that can identify an object class. You can read about MLP in any ML text book.   If you take a simple 1-2 layer neural network the weights are learned so that an input...

Image Matting using Machine Learning

Image matting is an interesting problem in computer vision that deals with identifying the foreground and background components of an image. While this may seem a fairly easy task, sometimes even experienced graphics professional find it difficult. Lets see the very famous example of dandelion image. Our task is to separate the background (green)...

How to setup JBLAS

Jblas is a linear algebra library for java developers to perform matrix operations easily. As we know  it is very difficult to program matrix operations .And Jblas provides us a number of inbuilt methods which we can use directly to perform matrix operations in few seconds. Jlbas provides matrix objects for different data types say DoubleMatrix,...

Machine Learning, Step Size

Machine Learning Concept - Step Size

At Numahub, training models is something we do more times in a week than having dinners with our better halves. While working with machine learning algorithms, especially the ones which use Gradient Descent for optimization, we often come across “step size”.  If you are a Machine Learning enthusiast I am pretty sure you would have come across this...
