One of the trade-offs of today’s technological progress is the big energy costs necessary to process digital information. To make AI models using silicon-based processors, we need to train them with huge amounts of data. The more data, the better the model. This is perfectly illustrated by the current success of large language models, such as ChatGPT. The impressive abilities of such models are due to the fact that huge amounts of data were used for their training.

The more data we use to teach digital AI, the better it becomes, but also the more computational power is needed.

This is why to develop AI further; we need to consider alternatives to the current status quo in silicon-based technologies. Indeed, we have recently seen a lot of publications about Sam Altman, the CEO of OpenAI topic.

The next “Spider-Verse” film may have a new animation style: AI.

Sony Pictures Entertainment (SPE) CEO Tony Vinciquerra does not mince words when it comes to artificial intelligence. He likes the tech — or at the very least, he likes the economics.

“We are very focused on AI. The biggest problem with making films today is the expense,” Vinciquerra said at Sony’s Thursday (Friday in Japan) investor event. “We will be looking at ways to…produce both films for theaters and television in a more efficient way, using AI primarily.”

Digital twin models may enhance future autonomous systems.

Systems controlled by next-generation computing algorithms could give rise to better and more efficient machine learning products, a new study suggests.

Using machine learning tools to create a digital twin, or a virtual copy, of an electronic circuit that exhibits chaotic behavior, researchers found that they were successful at predicting how it would behave and using that information to control it.

Chapter 6 (Finetuning LLMs for Classification) of Build an LLM from Scratch book is now finally available on the Manning website:

  • Introducing different LLM finetuning approaches
  • Preparing a dataset for text classification
  • Modifying a pretrained LLM for finetuning
  • Finetuning an LLM to identify spam messages
  • Evaluating the accuracy of a finetuned LLM classifier
  • Using a finetuned LLM to classify new data

In previous chapters, we coded the LLM architecture, pretrained it, and learned how to import pretrained weights from an external source, such as OpenAI, into our model. In this chapter, we are reaping the fruits of our labor by finetuning the LLM on a specific target task, such as classifying text, as illustrated in figure 6.1. The concrete example we will examine is classifying text messages as spam or not spam.

“The ORFAN study is an expanding global registry which will include long-term clinical and outcome data for 250,000 patients from around the world, and we are very pleased to publish these initial results,” said Keith Channon, MD, Professor of Cardiovascular Medicine at University of Oxford, Caristo Chief Medical Officer, and co-author of The Lancet publication.

“Coronary inflammation is a crucial piece of the puzzle in predicting heart attack risk. We are excited to discover that CaRi-Heart results performed exceptionally well in predicting patient cardiac events. This tool is well positioned to help clinicians identify high-risk patients with seemingly ‘normal’ CCTA scans.”

Ron Blankstein, MD, Professor of Medicine and Radiology at Harvard Medical School, Director of Cardiac Computed Tomography at Brigham and Women’s Hospital, and co-author of the publication, applauded The Lancet for publishing results from one of the largest studies in the field of CCTA.
