Type Inference means that the data type of any expression (e.g. method return type or parameter type) can be deduced automatically by the compiler. Groovy language is a good example of programming languages supporting Type Inference. Similarly, Java 8 Lambda expressions also support Type inference. Let's understand how it works with a...

When you take your Machine Learning Models to Production for Real Time Predictions

Problem We had a use case where we needed to use machine learning to make predictions in real time. To give an estimate of what we consider real time - latency less than 10 milliseconds for our predictions. In this blog, we would discuss what is needed to have the kind of latency for machine learning models that we can use in production....

Functional Interface for Lambda expressions : Java 8

As we already know that Lambda Expressions are used to support functional programming in Java. The default behaviour of Lambda expressions is to accept only those interfaces as reference variables which have only one abstract method. We call such interfaces Functional Interfaces. You could also name them as SAM, i.e., Single Abstract...
