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.

Summary


In this chapter, you learned how to predict stock prices. We covered the different machine learning algorithms that can help us in this. We tried Random Forest Regressor, Logistic Regression, and multilayer perceptron. We found out that the multilayer perceptron works really well. I really want to discuss something beyond what we have done so far. If you are under the impression that using the sentiment analysis of news and predictive methods, we can now correctly predict the stock market price with a hundred percent accuracy, then you would be wrong. We can't predict stock prices with a hundred percent accuracy. Many communities, financial organizations, and academic researchers are working in this direction in order to make a stock market price predictive model that is highly accurate. This is an active research area.

So if you are interested in research and freelancing, then you can join some pretty cool communities. There are two communities that are quite popular. One of these...
