DL4J Workshop at the ML Summit in Berlin
On October 1st and 2nd the first ML Summit takes place in Berlin. In 12 workshops in three parallel tracks, experts impart practical knowledge on the topics Applications for Business, Machine Learning Basics & Tools and Specialized Topics.
One of these workshops is hosted by our CTO. The topic is an introduction to Deep Learning with Java using DL4J. Step-by-step an example project is created by the attendees. The aim is that after four hours all participants will have learned the basics of using DL4J and a series of best practices for ML projects. The sample project is deliberately small so that all participants can use their own laptops. GPU acceleration will not be necessary. The workshop will be held in German. At the beginning of each work section there is a short presentation explaining the next work steps.

ChatGPT for Teams: Privacy-Compliant Use in the Workplace
In today’s digital business world, AI-powered communication platforms like ChatGPT are essential for tasks such as answering complex code questions or creating top-notch texts for offers. However, in companies dealing with sensitive customer data, using ChatGPT can lead to a data protection dilemma. While ChatGPT offers an option to prevent the use of chat conversations for training purposes, it comes with certain limitations. Moreover, as of June 2023, there is no way to manage multiple team members or users through a company account. Each user must register individually and use their own email, phone number, and credit card. If you want to use ChatGPT+, for example, you cannot pay for all users with one credit card. Individual invoices also end up with individual users, creating an organizational and accounting nightmare. We at DIVISO have also grappled with this issue and went in search of a solution.

Git as a management tool for training data and experiments in ML
In this part of the series of articles on MLOps, we start with information that will be familiar to most of you: With the basics of Git. However, to give a different perspective on the well-known tool, these basics provide the basis to highlight the function and benefits of Git for machine learning (ML) and the difference in managing training data.

Types of Artificial Neural Networks
In our real-world example, we used a “feed-forward neural network” to recognise handwritten numbers. This is probably the most basic form of a NN. In reality, however, there are hundreds of types of mathematical formulas that are used – beyond addition and multiplication – to compute steps in a neural network, many different ways to arrange the layers, and many mathematical approaches to train the network.

Amazon DJL - a new DL framework for Java
Developers who wanted to explore neural networks and deep learning using the JVM, and especially Java, had little choice so far. Those who wanted to focus exclusively on Java could not get around DL4J until now. If it had to be the JVM, but not necessarily Java, the MXNet Scala Frontend was also an option. Finally, if a little Python didn’t scare you, you could try a hybrid solution, combining TensorFlow and Java just like we already explained in previous articles.

NLP, NLU and NLG: AI and text
So far, we have generally steered clear of the areas of text comprehension and text generation by ML in our practical examples for the basic understanding of AI. For good reason, we have focused primarily on two types of problems: classification of images and prediction of numerical values.

Neural networks - The five most common mistakes
AI and especially Neural Networks or Deep Learning have been the technological hype topic for some years now. However, since the subject is quite abstract – one could say it is uncharted territory for most people – we want to clear up some mistakes that we often encounter in our work.

What are Neural Networks and how do they work?
In our past articles we mainly covered the basics of current AI research and tried to shed some light on them in a way that is understandable for non-IT scientists. We are now proceeding to the probably “hottest” current AI topic: Neural Networks (NN).

Deep Java Learning Introduction - Part 1: NDManager & NDArray
After our first presentation of Amazon’s new Deep Learning Framework for Java, DJL, we now want to introduce the basics of Deep Learning under Java with DJL step by step in a series of beginner posts. This is not about quickly copying code snippets, but about really understanding the framework and the concepts.

Deep Fakes - How to spot faked Images
A (fairly) new kind of neural networks, so-called Generative Adversarial Networks or GANs, are nowadays capable of generating deceptively real images of people that do not actually exist. These fake images are indistinguishable from real photos at first glance. Fortunately, you might still uncover them if you look closely – if you know what to look for!

Understanding AI - Part 5: Supervised & Unsupervised Learning in ML
In the previous article we introduced the basic concepts of Machine Learning and how the training of an ML model works, using a simple but practical algorithm. Next, we want to take a closer look at the different types of Machine Learning.

BGL symposium 2019 - lecture 'AI and Magic'
“Any sufficiently advanced technology is indistinguishable from magic.” – Arthur C. Clarke JAX 2019 is barely over, but Christoph is already on the podium for the next talk. At the symposium of the BLG (Federal Association of Industrial Photographic Laboratories), his lecture will cover “AI and Magic – How does Artificial Intelligence work?

Understanding AI - Part 4: The basics of Machine Learning
After shedding some light onto Symbolic AI in the previous article, we’re now moving on to take a closer look at Machine Learning (ML). When it comes to Symbolic AI, breaking down a problem as minutely as possible is key for successfully solving it.

Understanding AI - Part 3: Methods of symbolic AI
In the previous article we added two distinctions to our initial definition of AI: On the one hand we distinguish between strong and weak AI (Terminator & Science Fiction vs. the scientific status quo). Also we pointed out the difference between symbolic AI and Machine Learning.

Understanding AI - Part 2: Symbolic AI, Neural Networks and Deep Learning
Artificial Intelligence (AI) is as old as computer science itself. Calculations, logical deductions, complex assignments… all this was once restricted to humans, until computers came forth.

Understanding AI - Part 1: What is AI?
From household help to doomsday scenario - there’s hardly a topic where public perception, state of research and reality seem so incongruent as with artificial intelligence. Reason enough to shed some light onto this subject with a series of articles.
