Amazon announced today that a team from the Nova School of Science and Technology (FCT NOVA) in Portugal has achieved first place in Alexa Prize Taskbot Challenge 2. Complete complex tasks. Taskbot is the first conversational AI challenge to incorporate multimodal customer experiences. During the competition, in addition to verbal instructions, some customers with Echo … Read more
Reinforcement learning with human feedback (RLHF) is the default method of adjustment Large language models (LLMs) with human preferences – such as the preferences of non -toxic language and invoiced accurate resorts. Recently, one of the most popular RLHF methods has been direct preference optimization, where LLM chooses between two output options, one of which … Read more
Today’s major machine learning models-as generative language models or vision-language models, are so great that the process of educating them is typically divided across thousands or even tens of thousands of GPUs. Even with all that parallelism, training still often takes months. With such a massive implementation of resources, hardware and software errors are common … Read more
UT Austin-Amazon Science Hub has entered into the initial winners of two gift project awards and a doctorate trained scholarship. The prizes recognize researchers whose work meets the hub’s goals: To tackle current challenges through advanced technological solutions that will benefit society as a whole. The Amazon-funded collaboration launched in April 2023 and host of … Read more
Natural-Language and NLU) have long been a key focus of the papers that Amazon scientists publish at the conference on empirical methods for natural-langue treatment (EMNLP), but at this year’s conference that starts today, Amazon’s NLU research shows interest in utilizing the power of large language models (LLMS). The answer of the question also remains … Read more
When a large language model (LLM) is quick with a request such as Which medications are likely to interact with St. John’s Wort?It does not seek a medically validated list of drug interactions (unless it has been trained to do so). Instead, it generates a list based on the distribution of words associated with St. … Read more
Amazon and MIT have appointed the item in the 2023 gift project and the Fellowship Awards Grantd as part of the Science Hub. Science Hub-Administer at MIT by Schwarzman College of Computing-is a collaboration between Amazon and MIT, which leading research supports, education and abroad in the development of technologies such as machine learning and … Read more
For all their remacable abilies, large language models (LLMs) have an Achilles heel, which is their tendency to hallucinate or make claims that sound plausible but invoice inaccurate. Sometimes these hallucinations can be subtle: An LLM can, for example, make a claim that is most accurate, but gets a date wrong with only one year … Read more
Vision-language models that map images and text into a common representative space have shown remacable performance on a wide range of multimodal AI tasks. But they are typically trained on text images: Each text input is connected to a single image. This limits the usability of the models. For example, you may wish that a … Read more
Amazon and Iit Bombay (IIT-B) Today, the initial award announced Hart Cape from the Amazon IIT-Bombay AI-ML initiative. The prizes recognize researchers whose work meets the initiative’s goals: to promote artificial intelligence and machine learning research in speech, language and multimodal-IA domains. The Amazon-funded collaboration launched in March 2023 and the house in the IIT … Read more
