These implementation is just the same with Implementing A Neural Network From Scratch, except that in this post the input x or s is 1-D array, but in previous post input X is a batch of data represented as a matrix (each row is an example).Now that we are able to calculate the gra...

#This function learns parameters for the neural network and returns the model.#- nn_hdim1: Number of nodes in the first hidden layer#- nn_hidm2: Number of nodes in the second hidden layer(default 3)#- m: Size of minibatch#- num_passes: Number of passes through the training data for...
Microsoft fixed this by adding in a residual – a part of the previous layer’s input that will be processed to create the next layer’s output. This passes information to the next layer directly allowing the gradients from previous layers to pass through information even if their gradients ar...

This guide serves as a basic hands-on work to lead you through building a neural network from scratch. Most of the mathematical concepts and scientific decisions are left out.
neural network. The neural network has already learned a rich set of image features, but when you fine-tune the neural network it can learn features specific to your new data set. If you have a very large data set, then transfer learning might not be faster than training from scratch. ...
TensorFlow implementation of Accelerating the Super-Resolution Convolutional Neural Network [1]. This implementation replaces the transpose conv2d layer by a sub-pixel layer [2]. Includes pretrained models for scales x2, x3 and x4. Which were trained on T91-image dataset, and finetuned on Gene...
In this repository, I will show you how to build a neural network from scratch (yes, by using plain python code with no framework involved) that trains by mini-batches using gradient descent. Check nn.py for the code. In the related notebook Neural_Network_from_scratch_with_Numpy.ipynb ...
