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.

Understanding the datasets


In this chapter, we are using two datasets, as follows:

  • E-commerce item data

  • Book-Crossing dataset

e-commerce Item Data

This dataset contains data items taken from actual stock keeping units (SKUs). It is from an outdoor apparel brand's product catalog. We are building the recommendation engine for this outdoor apparel brand's product catalog. You can access the dataset by using this link: https://www.kaggle.com/cclark/product-item-data/data.

This dataset contains 500 data items. There are two columns in the dataset.

  • ID: This column indicates the indexing of the data item. In layman's terms, it is the serial number of the dataset.

  • Description: This column has all the necessary descriptions about the products, and we need to use this data to build the recommendation engine.

You can refer to the following figure:

As you can see, the description column has textual data, and we need to process this textual dataset in order to...
