Sparse Autoencoders (SAEs) are a type of neural network that efficiently learns data representations by enforcing sparsity, capturing only the most essential data characteristics. This process reduces dimensionality and improves generalization to unseen information.
Language model (LM) activations can be approximated using SAEs. They do this by sparsely decomposing the activations into linear components using…
In our fast-paced digital era, personalized experiences are integral to all customer-based interactions, from customer support and healthcare diagnostics to content recommendations. Consumers necessitate technology to be tailored towards their specific needs and preferences. However, creating a personalized experience that can adapt and remember past interactions tends to be an uphill task for traditional AI…
Researchers at MIT and the University of Washington have developed a model to estimate the computational limitations or "inference budget" of an individual or AI agent, with the ultimate objective of enhancing the collaboration between humans and AI. The project, spearheaded by graduate student Athul Paul Jacob, proposes that this model can greatly improve the…
Researchers from MIT and the MIT-IBM Watson AI Lab have designed a machine-learning accelerator that is impervious to the two most common types of cyberattacks. Currently, healthcare apps that monitor chronic diseases or fitness goals are relying on machine learning to operate. However, the voluminous machine-learning models utilized need to be transferred between a smartphone…

The sheer number of academic papers released daily has resulted in a challenge for researchers in terms of tracking all the latest advances. One way to make this task more efficient is to automate the process of data extraction, particularly from tables and figures. Traditionally, the process of extracting data from tables and figures is…
In the field of natural language processing (NLP), integrating external knowledge bases through Retrieval-Augmented Generation (RAG) systems is a vital development. These systems use dense retrievers for pulling relevant information, utilized by large language models (LLMs) to generate responses. Despite their improvements across numerous tasks, there are limitations to RAG systems, such as struggling to…
Large Language Models (LLMs), which focus on understanding and generating human language, are a subset of artificial intelligence. However, their use of the Transformer architecture to process long texts introduces a significant challenge due to its quadratic time complexity. This complexity is a barrier to efficient performance with extended text inputs.
To deal with this issue,…
Designing computation workflows for AI applications faces complexities, requiring the management of various parameters such as prompts and machine learning hyperparameters. Improvements made post-deployment are often manual, making the technology harder to update. Traditional optimization methods like Bayesian Optimization and Reinforcement Learning often call for greater efficiency due to the intricate nature of these systems.…
