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.

Chapter 6. Job Recommendation Engine

We have already seen how to develop a recommendation system for the e-commerce product in Chapter 4, Recommendation Systems for e-Commerce, Now, we will apply the same concepts that you learned in Chapter 4, Recommendation Systems for e-Commerce but the type and format of the dataset is different. Basically, we will build a job recommendation engine. For this application, we have taken into account the text dataset. The main concept of building the recommendation engine will not change, but this chapter gives you a fair idea of how to apply the same concepts to different types of datasets.

In this chapter, we will cover the following topics:

  • Introducing the problem statement

  • Understanding the datasets

  • Building the baseline approach

    • Implementing the baseline approach

    • Understanding the testing matrix

    • Problems with the baseline approach

    • Optimizing the baseline approach  

  • Building the revised approach

    • Implementing the revised approach

    • Testing the revised approach

    • Problems...
