In my previous article,Build an Artificial Neural Network(ANN) from scratch: Part-1we started our discussion about what are artificial neural networks; we saw how to create a simple neural network with one input and one output layer, from scratch in Python. Such a neural network is called ...
We'll do a quick OOP review in this post to cover the details needed for working with PyTorch neural networks, but if you find that you need more, the Python docs have an overview tutorial here. To build a convolutional neural network, we need to have a general understanding of how CNN...

In terms of the architecture, Skip-gram is a simple neural network with only one hidden layer. The input to the network is a one-hot encoded vector representation of a target-word — all of its dimensions are set to zero, apart from the dimension corresponding to the target-word...
Simple MNIST one layer NN as the backdrop First of all, we need some ‘backdrop’ codes to test whether and how well our module performs. Let’s build a very simple one-layer neural network to solve the good-old MNIST dataset. The code (running in Jupyter Notebook) snippet bel...
In the most basic neural network, the input of those algorithms are fixed size vectors, which are computed to obtain a fixed-size result. For example, with image classification a single input vector (the image) produces a single vector of probabilities (ie., the likelihood that the image is...
