Learn and implement Haar cascade classifier in projects… Viola Jones Algorithm The Viola-Jones object detection framework is a machine learning approach for object detection, proposed by Paul Viola and Micheal Jones in 2001. This framework can be trained to detect almost any object, but this primarily solves the problem of face detection in…

An approach to understanding pooling layers and effect on backpropagation CNNs work on a weight sharing strategy, neurons are able to perform convolutions on the data with the convolution filter being formed by the weights. Pooling operation then follows which reduces the spacial size of the representation thus reducing the…

Random number have lots of application like, cryptography, game and Neural Network. Here we’ll discuss and identify different methods for generating random numbers in NumPy module in python. import numpy as np numpy.random.random (size)— Return random floats in the half-open interval [0.0, 1.0), ie 1.0>x≥0.0 >>>np.random.random((2,2)) array([[ 0.66032591, 0.91397527]…
