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 revised approach


Now we will be coding the algorithm that we discussed in the previous section. After implementing it, we will check how well or badly our algorithm is performing. This algorithm is easy to implement, so let's begin with the code. You can find the code at this GitHub link: https://github.com/jalajthanaki/medical_notes_extractive_summarization/tree/master/Revised_approach.

Implementing the revised approach

In this section, we will be implementing the summarization algorithm step by step. These are the functions that we will be building here:

  • The get_summarized function

  • The reorder_sentences function

  • The summarize function

Let's begin with the first one.

The get_summarized function

Basically, this function performs the summarization task. First, it will take the content of the document as input in the form of string. After that, this function generates the frequency of the words, so we need to tokenize the sentences into words. After that, we will be generating the top...
