Pixel values range from zero to 255. In order to use them, you’ll need to normalize them to values between zero and one. Use the following code to do that: XML X_train = X_train / 255 X_test = X_test / 255 Then enter the following code to take a look at what the data look...
Also, if you’re using an IDE, you don’t need to do all of this manually. For example: in Eclipse, you can generate a toString method by opening the Book.java and right-click on the source code and select: Source > Generate > toString It would differ for different IDE’s. So, j...
The key here is to realize that the body of the function—whether written in C# or in F#—is of a specific .NET-type signature: Func<object, Task>. The asynchrony here is necessary because remember that Node prefers callbacks to direct sequential execution in order to avoid blocking the...

Error: java.lang.ClassNotFoundException: Failed to find data source: es. If you see this error when trying to write data from Spark to Elasticsearch in the notebook, it means that the Elasticsearch Spark connector (elasticsearch-spark-20_2.11-7.6.2.jar) was not found on the class path by...
Arraysdon't support that, they need a size beforehand. So, what should we do? Do not worry, as Java is here to help us again. Let's explore it then! What is Linked List Data Structure in Java? LinkedList is a linear data structure similar to arrays in Java. LinkedList items, on ...

There are two algorithms supported to traverse the graph in Java. Depth-first traversal Breadth-first traversal Depth-first Traversal Depth-first search (DFS) is a technique that is used to traverse a tree or a graph. DFS technique starts with a root node and then traverses the adjacent node...
to perform tasks such as creating new processes and communicating with other processes. Many of the tools that you see in this chapter are often thought of as performance-monitoring tools. They’re particularly helpful if your system is slowing to a crawl and you’re trying to figure out why...
The calculation method is commonly used to calculate the cyclomatic complexity of the structure: the sequential structure has a complexity of 1. if-else-else, switch-case: Every time a branch is added, the complexity increases by 1, and the && and || operations are also a branch. ...
