brings coffee into Java

The monthly meetups for Java professionals who would like to be interactive and allow technology enthusiasts to learn from other professionals, have questions answered in real-time, discover new tech and solutions.

CoffeeJUG: Java Anniversary

Java Modules (aka JPMS) for day-to-day Java developers

By Rafael Benevides

Java 14 has been released recently and a feature introduced in Java 9 stills a mystery for many Java developers. JPMS is a change to the Java libraries, language, and runtime. This means that it affects the whole stack that developers code with day-to-day, and as such JPMS could have a big impact. For compatibility reasons, most existing code can ignore JPMS. However, have you wondered what you as a developer can benefited from using Java Modules in your application? Come to this session and learn how to use Java Modules, and what are the benefits to you.

Machine Learning: The Bare Math Behind Libraries (Unsupervised Part)

By Piotr Czajka

Within unsupervised learning, you will become familiar with Hebb’s learning and learning with concurrency (winner takes all and winner takes most algorithms). We will use Octave for examples in this session; however, you can use your favorite technology to implement presented ideas.

Our aim is to show the mathematical basics of neural networks for those who want to start using machine learning in their day-to-day work or use it already but find it difficult to understand the underlying processes. After viewing our presentation, you should find it easier to select parameters for your networks and feel more confident in your selection of network type, as well as be encouraged to dive into more complex and powerful deep learning methods.
