The article discusses a new model called StructBERT that enhances the performance of BERT, a popular language model for natural language processing tasks. StructBERT modifies the pretraining objectives of BERT by introducing word sentence and sentence structural objectives. These modifications improve the model’s ability to understand word order and inter-sentence relations, resulting in better performance…

Researchers from Singapore University of Technology and Design and Queen Mary University of London have developed Mustango, a text-to-music system that allows for control over musical aspects. By incorporating music-specific features into the diffusion denoising process, Mustango enables the creation of music clips with specific conditions such as chord progression, tempo, and key selection. The…

Researchers at Los Alamos National Laboratory have developed a new artificial intelligence (AI) approach called Senseiver that allows for efficient data processing. Senseiver uses a neural network to represent extensive data with minimal computational resources, reducing computing requirements. The AI model has been successfully applied to tasks such as forecasting oceanic temperatures and has implications…

Researchers from Nankai University and ByteDance have developed a framework called ChatAnything that generates anthropomorphized personas for large language model (LLM)-based characters. The framework uses in-context learning and system prompts to create customized personalities, voices, and visual appearances. It introduces innovative concepts, MoV and MoD, for voice and appearance generation. The researchers address challenges in…

A team of researchers has introduced a parameter-efficient method called Orthogonal Butterfly (BOFT) for fine-tuning large language models in the field of Artificial Intelligence. BOFT addresses the challenge of maintaining relational information and reduces the number of trainable parameters. Inspired by the Cooley-Tukey fast Fourier transform technique, BOFT uses sparse matrix factorization to create a…

Animated word clouds are a dynamic visualization tool that display the frequencies of words over time. They provide a time perspective to the classic word cloud and can be generated using Python. The AnimatedWordCloud library offers features like n-gram frequency visualization and text cleaning. The library can be installed and used to generate frames and…

Nvidia researchers have introduced a method called neural radiance field (NeRF) formulation for view synthesis. This approach efficiently transitions between volumetric and surface-based rendering by constructing a mesh envelope around a neural volumetric representation. The method significantly accelerates rendering speed, particularly in solid regions, and showcases high-fidelity rendering for animation and simulation applications. The proposed…
