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.

Introducing problem statements


We are living in a competitive world. Before buying any product and investing our time or money in anything, we try to find out what others think about that product(s) or service(s). We try to analyze their reviews or opinions. If we find them positive and trustworthy, then we buy the product and invest our money or time in that particular service. On the other hand, if we find these opinions or reviews negative, then we might not buy the product and not invest our money or time in that particular service. In the current era of the internet, it is easy to find reviews on social media platforms, blogs, news sources, and so on. This activity of analyzing reviews will be useful for consumers as well as makers of products or service providers. This is because, based on the reviews of their customer, they can change their product effectively, providing more satisfaction to their customers and make a good profit from that product or service.
