Overview of this book

Machine learning (ML) helps you find hidden insights from your data without the need for explicit programming. This book is your key to solving any kind of ML problem you might come across in your job. You’ll encounter a set of simple to complex problems while building ML models, and you'll not only resolve these problems, but you’ll also learn how to build projects based on each problem, with a practical approach and easy-to-follow examples. The book includes a wide range of applications: from analytics and NLP, to computer vision domains. Some of the applications you will be working on include stock price prediction, a recommendation engine, building a chat-bot, a facial expression recognition system, and many more. The problem examples we cover include identifying the right algorithm for your dataset and use cases, creating and labeling datasets, getting enough clean data to carry out processing, identifying outliers, overftting datasets, hyperparameter tuning, and more. Here, you'll also learn to make more timely and accurate predictions. In addition, you'll deal with more advanced use cases, such as building a gaming bot, building an extractive summarization tool for medical documents, and you'll also tackle the problems faced while building an ML model. By the end of this book, you'll be able to fine-tune your models as per your needs to deliver maximum productivity.

The best approach


Here, we are going to implement the neural network-based algorithm multilayer perceptron (MLP). You can refer to the following code snippet:

Figure 2.37: Code snippet for multilayer perceptron

Here, you can see that we are using the Relu activation function, and the gradient descent solver function is ADAM. We are using a learning rate of 0.0001. You can evaluate the result by referring to the following graph:

Figure 2.38: Code snippet for generating the graph for the actual and predicted prices

This graph shows that all the data records' predicted prices follow the actual price pattern. You can say that our MLP model works well to predict the stock market prices. You can find the code at this GitHub link: https://github.com/jalajthanaki/stock_price_prediction/blob/master/Stock_Price_Prediction.ipynb.
