In the domain of large language models (LLMs), text-to-speech (TTS) synthesis presents a unique challenge, and researchers are exploring their potential for audio synthesis. Historically, systems have used various methodologies, from reassembling audio segments to using acoustic parameters, and more recently, generating mel-spectrograms directly from text. However, these methods face limitations like lower fidelity and…
Nvidia, a leading name in the advanced technology industry, has revolutionized the realm of audio synthesis with the introduction of its neural vocoder, BigVGAN v2. This breakthrough technology stands apart in the field by virtue of its record-breaking speed, unparalleled sound quality, and adaptability, transforming Mel spectrograms into high-fidelity waveforms.
One of the standout features of…
Researchers from the Improbable AI Lab at MIT and the MIT-IBM Watson AI Lab have developed a new technique to improve "red-teaming," a process of safeguarding large language models, such as AI chatbot, through the use of machine learning. The new approach focuses on the automatic generation of diverse prompts that result in undesirable responses…
Researchers from MIT, in collaboration with the Broad Institute of MIT and Harvard and Massachusetts General Hospital, have introduced a new artificial intelligence (AI) tool known as Tyche, which can provide multiple, plausible image segmentation possibilities for a given medical image. Unlike conventional AI tools, which typically offer a single definitive interpretation, Tyche generates a…
Neural networks have been of immense benefit in the design of robot controllers, boosting the adaptive and effectiveness abilities of these machines. However, their complex nature makes it challenging to confirm their safe execution of assigned tasks. Traditionally, the verification of safety and stability are done using Lyapunov functions. If a Lyapunov function that consistently…
Biomedicine often requires the annotation of pixels in a medical image to identify critical structures such as organs or cells, a process known as segmentation. In this context, artificial intelligence (AI) models can be useful to clinicians by highlighting pixels indicating potential disease or anomalies. However, decision-making in medical image segmentation is frequently complex, with…
Researchers from the Massachusetts Institute of Technology's (MIT) Computer Science and Artificial Intelligence Laboratory (CSAIL) have developed an algorithm to mitigate the risks associated with using neural networks in robots. The complexity of neural network applications, while offering greater capability, also makes them unpredictable. Current safety and stability verification techniques, called Lyapunov functions, do not…
Amazon Web Services (AWS) has developed a solution using the AWS generative artificial intelligence (AI) service, Amazon Q Business, to provide actionable insights based on support data, which enhances the operation and health of AWS environments. Amazon Q Business is a generative AI-powered enterprise chat assistant that enables natural language interactions with an organization's data.…
