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 datasets


This section is divided into two parts. In the first part, we need to discuss the challenges we have faced in order to generate the dataset. In the later section, we will be discussing the attributes of the dataset.

Challenges in obtaining the dataset

As we all know, the health domain is a highly regulated domain when it comes to obtaining the dataset. These are some of the challenges I want to highlight:

  • For summarization, ideally, we need to have a corpus that contains original text as well as a summary of that text. This is called parallel corpus. Unfortunately, there is no good, free parallel corpus available for medical document summarization. We need to obtain this kind of parallel dataset for the English language.

  • There are some free datasets available, such as the MIMIC II and MIMIC III dataset, but they won't contain summaries of the medical transcription. We can access just the medical transcription from this dataset. Gaining access to this dataset is a lengthy...
