Key concepts for model building in ML
In our previous post, we’ve discussed about the buzzword “Machine Learning“, types of machine learning and machine learning problems. In this post we’ll be learning about the steps involved in building a machine learning model. Steps involved to build a machine learning model As every learning process involve a sequence of steps, machine learning also…

Machine Learning for Beginner’s
The following series of blogs run in parallel with the Artificial Neural Networks(A.N.N) which enables you to take baby step’s in Machine Learning. What exactly is Machine Learning ? Machine Learning is an ability given to a machine to sense, act and react to a particular situation. In the above picture,the model detects the objects…

Multi layer Neural Networks Back Propagation
In our previous post, we discussed about the implementation of perceptron, a simple neural network model in Python. In this post, we will start learning about multi layer neural networks and back propagation in neural networks. The back propagation algorithm is capable of expressing non-linear decision surfaces. So, what is non-linear and what exactly is…

Perceptron – Delta Rule Python Implementation
In our previous post, we discussed about training a perceptron using The Perceptron Training Rule. In this blog, we will learn about The Gradient Descent and The Delta Rule for training a perceptron and its implementation using python. Why Gradient Descent ? As we have discussed earlier, the perceptron training rule works for the training…

Artificial Neural Networks: Perceptron
Perceptron is a simple model of a biological neuron in an Artificial Neural Network. Perceptrons are used for supervised binary classification problems. A perceptron takes a set of real-valued inputs and finds a linear combination of them and maps the output to either of the class. What is Binary Classification ? Binary classification refers to…

Introduction to Artificial Neural Networks
Artificial Neural Networks are the learning algorithms which simulate biological networks of our human brain. They are one of the most effective learning algorithms currently known. They provide a robust approach for approximating : real-valued discrete-valued vector-valued target functions. Biological Motivation : Aritificial neural networks are inspired by biological learning systems which are built of…
