Large language models (LLMs) have significantly advanced our capabilities in understanding and generating human language. They have been instrumental in developing conversational AI and chatbots that can engage in human-like dialogues, thus improving the quality of various services. However, the post-training of LLMs, which is crucial for their efficacy, is a complicated task. Traditional methods…
The technique of language model adaptation is integral in artificial intelligence as it aids in modifying large pre-existing language models to function effectively across a range of languages. Notwithstanding their remarkable performance in English, these language learning models' (LLM) capabilities tend to diminish considerably when adapted to less familiar languages. This necessitates the implementation of…
Language models are advanced artificial intelligence systems that can generate human-like text, but when they're trained on large amounts of data, there's a risk they'll inadvertently learn to produce offensive or harmful content. To avoid this, researchers use two primary methods: first, safety tuning, which is aligning the model's responses to human values, but this…
Large Language Models (LLMs) have become essential tools in various industries due to their superior ability to understand and generate human language. However, training LLMs is notably resource-intensive, demanding sizeable memory allocations to manage the multitude of parameters. For instance, the training of the LLaMA 7B model from scratch calls for approximately 58 GB of…
Large language models (LLMs) are pivotal in advancing artificial intelligence and natural language processing. Despite their impressive capabilities in understanding and generating human language, LLMs still grapple with the issue of improving the effectiveness and control of in-context learning (ICL). Traditional ICL methods often suffer from uneven performance and significant computational overhead due to the…
Patronus AI has recently announced Lynx, an advanced hallucination detection model that promises to outperform others in the market such as GPT-4 and Claude-3-Sonnet. AI hallucination refers to cases where AI models create statements or information unsupported or contradictory to provided context. Lynx represents a significant enhancement in limiting such AI hallucinations, particularly crucial in…
Developing custom AI models can be time-consuming and costly due to the need for large, high-quality datasets. This is often done through paid API services or manual data collection and labeling, which can be expensive and time-consuming. Existing solutions such as using paid API services that generate data or hiring people to manually create datasets…
A team of researchers from MIT, Digital Garage, and Carnegie Mellon has developed GenSQL, a new probabilistic programming system that allows for querying generative models of database tables. The system extends SQL with additional functions to enable more complex Bayesian workflows, integrating both automatically learned and custom-designed probabilistic models with tabular data.
Probabilistic databases use algorithms…
The MIT Stephen A. Schwarzman College of Computing recently celebrated the completion of its new Vassar Street building. The dedication ceremony was attended by members of the MIT community, distinguished guests, and supporters, reflecting on the transformative gift from Stephen A. Schwarzman that initiated the biggest change to MIT’s institutional structure in over 70 years.…
Large Language Models (LLMs) are pivotal for numerous applications including chatbots and data analysis, chiefly due to their ability to efficiently process high volumes of textual data. The progression of AI technology has amplified the need for superior quality training data, critical for the models' function and enhancement.
A major challenge in AI development is guaranteeing…
Advances in technology over the past century, specifically the proliferation of computers, has facilitated the development of molecular representations that can be understood by these machines, assisting the process of drug discovery. Initial representations of molecules were simplified, showing only bonds and atoms. However, as the complexity of computational processing increased, more sophisticated representations were…
The increase in the hidden layer width of feedforward (FFW) layers results in linear growth in computational costs and activation memory in transformer architectures. This causes a significant issue in scaling, especially with increasingly complex models. These challenges affect the deployment of large-scale models in real-world applications, including language modeling and natural language processing.
Previously, Mixture…
