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.

Building the baseline approach


From this section onward, we will focus on how to build the basic version of the recommendation engine (which means the recommendation system in the context of this chapter). In order to develop the baseline approach, we will be using the content-based approach. These are the topics that we will be covering:

  • Understanding the basic concepts

  • Implementing the baseline approach

  • Understanding the testing matrix

  • Testing the result of the baseline approach

  • Problems with the baseline approach

  • Learning optimization tricks for the baseline approach

Without wasting any time, let's look at how the content-based approach has been used to build the recommendation engine.

Understanding the basic concepts

As I've specified earlier, we are using the content-based approach. You must be wondering what this approach is and how I have decided to use it. In order to find the answers to these questions, we need to understand the approach first, and then we can discuss why I chose it.
