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.

Problems with the existing approach


In this section, we will discuss the problems with the basic version of our chatbot. As we already know, for unseen queries this approach doesn't work, which means that the basic approach is not able to generalize the user's questions properly.

I have listed down some of the problems here:

  • Time consuming because we need to hardcode each and every scenario, which is not feasible at all

  • It cannot work for unseen use cases

  • The user should process the rigid flow of conversation

  • It cannot understand the long context

Most of these problems can be solved using the generative-based approach. Let's look at the key concepts that will help us improvise this approach.

Understanding key concepts for optimizing the approach

In this section, we will be discussing the key concepts that can help us improvise the chatbot basic version. The problems that we have listed down previously can be solved by using Deep Learning (DL) techniques, which can help us build a more generalized...
