Let's build an ANN from scratch using Python and NumPy without relying on deep learning libraries such as TensorFlow or PyTorch. This approach will help in better understanding of the workings of neural networks. Your All-in-One Learning Portal: GeeksforGeeks is a comprehensive educational platform that empowers learners across domains-spanning computer science and programming, school education, upskilling, commerce, software tools, competitive exams, and more. An Artificial Neural Network (ANN) is modeled on the brain where neurons are connected in complex patterns to process data from the senses, establish memories and control the body. Learn about ANN, a deep learning method that mimics the human brain to model complex patterns and forecast issues. Explore the architecture, types, benefits, applications, and disadvantages of ANN, and build a simple ANN model using Python and Keras.
