neural networkpredictionregressionThe article examines the practical implementation of Artificial Intelligence technologies, Machine Learning and Deep Learning technologies. Methods of construction and prediction of neural networks are considered using special libraries of Python language. Linear regression and ...
In this article, we will walk through the process of creating a neural network from scratch using Python. We will use the classic Iris dataset to demonstrate how our neural network works. By the end of this tutorial, you'll have a good understanding of the fundamentals of neural networks an...
Theinput_shapeparameter is something you must assign based on your dataset. Intuitively speaking, it is the shape of the input data that the network should expect. I like to think of it as —“what is the shape of asinglerow of data that I am feeding into the neural netwo...

Create a Neural Network from Scratch: Explains how to build a basic neural network using Python, to predict house prices, while covering core concepts like gradient descent, backpropagation, and more. Text mining in Python - case-study with “Romeo and Juliet...
NetworkX is aPythonpackage for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks. It provides: tools for the study of the structure and dynamics of social, biological, and infrastructure networks; ...
A beginner-friendly guide on using Keras to implement a simple Neural Network in Python. June 14, 2019 | UPDATEDSeptember 20, 2022 Kerasis a simple-to-use but powerful deep learning library for Python. In this post, we’ll see how easy it is to build a feedforward neural network ...
A recurrent neural network has multiple time steps, which we'll index with tt. In the lessons, we saw a single training example x(i)x(i) consist of multiple time steps TxTx. For example, if there are 10 time steps, Tx=10Tx=10 Batches of size mm Let's say we have mini-batches,...
