Data Analytics Workouts

As part of understanding neural networks I was reading Make Your Own Neural Network by Tariq Rashid. A review is below: Make Your Own Neural Network by Tariq Rashid My rating: 4 of 5 stars The book itself can be painful to work through, as it is written for a novice, not just in algorithms and data analysis, but also in programming. For the neural network aspect, it jumped between overly simplistic and complicated, while providing neither in enough detail. That said, by the end I found it a worthwhile dive into neural networks, since once it got to the programming structure, it all made sense, but only because I stuck with it. View all my reviews

Introduction As part of understanding neural networks I was reading Make Your Own Neural Network by Tariq Rashid. The book itself can be painful to work through, as it is written for a novice, not just in algorithms and data analysis, but also in programming. Although the code is a verbatim transcription from the text (see Source section), I published it to better understand how neural networks are designed, made easy by the use of a Jupyter Notebook, not to present this as my own work, although I do hope that this helps others develop their talents with data analytics.  Github Source:  AzureNotebooks/Basic Three Layer Neural Network in Python.ipynb at master · JamesIgoe/AzureNotebooks (github.com) Overview The code itself develops as follows: Constructor set number of nodes in each input, hidden, output layer link weight matrices, wih and who weights inside the arrays are w_i_j, where link is from node i to node j in the next layer set learning rate activat...
