The number of satellites orbiting the Earth has grown exponentially in recent years, both due to lower costs and a rise in demand for services that satellites can provide, such as broadband internet and climate surveillance. However, this increase in activity also raises concerns around safety, security, and the environment, necessitating enhanced methods for monitoring…
MIT researchers have developed a technique for improving the accuracy of uncertainty estimates in machine-learning models. This is especially important in situations where these models are used for critical tasks such as diagnosing diseases from medical imaging or filtering job applications. The new method works more efficiently and is scalable enough to apply to large…
Artificial intelligence (AI) and particularly large language models (LLMs) are not as robust at performing tasks in unfamiliar scenarios as they are positioned to be, according to a study by researchers from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL).
The researchers focused on the performance of models like GPT-4 and Claude when handling “default tasks,”…
BRIA AI 2.0 is a high-resolution (1024x1024) text-to-image diffusion model. It was trained by BRIA AI on a dataset of licensed images, through a quick and economic process with the assistance of Amazon SageMaker, a platform that offers tools and workflows to build, train, and deploy machine learning models. BRIA AI specializes in generative artificial…
Retrieval Augmented Generation (RAG) enhances the performance of large language models (LLMs) by incorporating extra knowledge from an external data source, which wasn't involved in the original model training. The two main components of RAG include indexing and retrieval.
Despite their merits, pre-trained embeddings models, trained on generic datasets like Wikipedia, often struggle to effectively portray…
Ensuring the safety of large language models (LLMs) is vital given their widespread use across various sectors. Despite efforts made to secure these systems, through approaches like reinforcement learning from human feedback (RLHF) and the development of inference-time controls, vulnerabilities persist. Adversarial attacks have, in certain instances, been able to circumvent such defenses, raising the…
Numina has released a new language model optimized for solving mathematical problems: NuminaMath 7B TIR. With its 6.91 billion parameters, the model efficiently handles intricate mathematical queries through a specialized tool-integrated reasoning (TIR) system. Comprising a sequence of steps - creating a reasoning pathway for problem-solving, translating it into Python code, running the code in…
Artificial Intelligence (AI) and Machine Learning (ML) are transforming the field of cybersecurity by enhancing both defensive and offensive capabilities. On the defensive end, they are assisting systems to better detect and tackle cyber threats. AI and ML algorithms are proficient in dealing with vast datasets, thereby effectively identifying patterns and anomalies. These techniques have…
A group of researchers from Stanford University, UC San Diego, UC Berkeley, and Meta AI has proposed a new class of sequence modeling layers that blend the expressive hidden state of self-attention mechanisms with the linear complexity of Recurrent Neural Networks (RNNs). These layers are called Test-Time Training (TTT) layers.
Self-attention mechanisms excel at processing extended…
Complex tasks in software development often lead to a decrease in user experience quality and spike in business costs due to engineers pushing off tasks for later. However, Fume, a startup that uses Artificial Intelligence (AI) can efficiently address these complicated issues that include sentry mistakes, bugs, and feature requests.
Fume is known for its…
New research by MIT economist David Autor finds that since 1980, technology has replaced more U.S. jobs than it has created. It is a shift Autor attributes to an increased rate of automation and a slower rate of augmentation. Augmentation represents scenarios where technology drives the creation of new tasks, ultimately generating new job roles.…
