# Protocol of the current implementation of packt library

## Get the current book via productId

**URL:**

`https://services.packtpub.com/free-learning-v1/offers?dateFrom=date1&dateTo=date2`

Example form of the dates are `dateFrom=2019-02-05T00:00:00.000Z&dateTo=2019-02-06T00:00:00.000Z`.

This will result in a JSON object like the following:

```
{
	"data":[
			{
				"id":"af68913d-aef1-489c-be98-8bf91f53a754",
				"productId":"9781785889622",
				"availableFrom":"2019-02-05T00:00:00.000Z",
				"expiresAt":"2019-02-06T00:00:00.000Z",
				"limitedAmount":false,
				"amountAvailable":null,
				"details":null,
				"priority":0,
				"createdAt":"2019-01-24T12:20:41.677Z",
				"updatedAt":"2019-01-24T12:20:41.677Z",
				"deletedAt":null
			}
		],
	"count":1
}
```

Here, the information **"productId":"9781785889622"** is needed and useful.

Machine learning applications are everywhere, from self-driving cars, spam detection, document search, and trading strategies, to speech recognition. This makes machine learning well-suited to the present-day era of Big Data and Data Science. The main challenge is how to transform data into actionable knowledge.</p>\r\n<p>In this book you will learn all the important Machine Learning algorithms that are commonly used in the field of data science. These algorithms can be used for supervised as well as unsupervised learning, reinforcement learning, and semi-supervised learning. A few famous algorithms that are covered in this book are Linear regression, Logistic Regression, SVM, Naive Bayes, K-Means, Random Forest, TensorFlow, and Feature engineering. In this book you will also learn how these algorithms work and their practical implementation to resolve your problems. This book will also introduce you to the Natural Processing Language and Recommendation systems, which help you run multiple algorithms simultaneously.</p>\r\n<p>On completion of the book you will have mastered selecting Machine Learning algorithms for clustering, classification, or regression based on for your problem.</p>",
