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, we looked at how to analyze a dataset using various statistical techniques. After that, we obtained a basic approach and, by using that approach, we developed a model that didn't even achieve the baseline. So, we figured out what had gone wrong in the approach and tried another approach, which solved the issues of our baseline model. Then, we evaluated that approach and optimized the hyper parameters using cross-validation and ensemble techniques in order to achieve the best possible outcome for this application. Finally, we found out the best possible approach, which gave us state-of-the-art results. You can find all of the code for this on GitHub at https://github.com/jalajthanaki/credit-risk-modelling. You can find all the installation related information at https://github.com/jalajthanaki/credit-risk-modelling/blob/master/README.md.

In the next chapter, we will look at another very interesting application of the analytics domain: predicting the stock price of a given share. Doesn't that sound interesting? We will also use some modern machine learning (ML) and deep learning (DL) approaches in order to develop stock price prediction application, so get ready for that as well!
