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 the dataset


In this section, we will cover the dataset on which the Deep Learning models have been trained. There are two datasets that are heavily used when we are trying to build the object detection application, and those datasets are as follows:

  • The COCO dataset

  • The PASCAL VOC dataset

We will look at each of the datasets one by one.

The COCO dataset

COCO stands for Common object in context. So, the short form for this dataset is the COCO dataset. Many tech giants, such as Google, Facebook, Microsoft, and so on are using COCO data to build amazing applications for object detection, object segmentation, and so on. You can find details regarding this dataset at this official web page:

The COCO dataset is a large-scale object detection, segmentation, and captioning dataset. In this dataset, there are a total of 330,000 images, of which more than 200,000 are labeled. These images contain 1.5 million object instances with 80 object categories. All the...
