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.

Discussing the hybrid approach


In a real-life scenario, in order to build the chatbot we can also combine some of the techniques described here. As per the business needs we can use a hybrid approach.

Let's take an example. Suppose you are building a chatbot for the finance domain. If a user asks for the available balance in his account then we just need a rule-based system, which can query the database and generate the account balance details for that user. If a user asks how he can transfer money from one account to the other account, the chatbot can help the user by generating step-by-step information on how to transfer money. Here, we will use the deep learning-based generative approach. We should have one system that includes a rule-based engine as well as a deep learning algorithm to generate the best possible output. In this system, a user's question first goes to the rule-based system. If that question's answer can be generated by the rule-based system, then the answer will be passed...
