Traditional fully-connected feedforward neural networks or Multi-layer Perceptrons (MLPs), while effective, suffer from limitations such as high parameter usage and lacking interpretability in complex models such as transformers. These issues have led to the exploration of more efficient and effective alternatives. One such refined approach that has been attracting attention is the Kolmogorov-Arnold Networks (KANs),…
Eric Liu and Ashely Peake, first-year students in the Social and Engineering Systems (SES) doctoral program within the MIT Institute for Data, Systems, and Society (IDSS), started their academic journey keen on overcoming housing inequality issues. They had their first hands-on research experience by participating in the MIT Policy Hackathon. Run by students from IDSS…
Researchers from East China University of Science and Technology and Peking University have conducted a survey exploring the use of Retrieval-Augmented Language Models (RALMs) within the field of Natural Language Processing (NLP). Traditional methods used in this field, such as Convolutional Neural Networks (CNN), Recurrent Neural Networks (RNN), and Long Short Term Memory (LSTM), have…
Language models that can recognize and generate human-like text by studying patterns from vast datasets are extremely effective tools. Nevertheless, the traditional technique for training these models, known as "next-token prediction," has its shortcomings. The method trains models to predict the next word in a sequence, which can lead to suboptimal performance in more complicated…
The landscape for open-source Large Language Models (LLMs) has expanded rapidly, especially after Meta's launches of the Llama3 model and its successor, Llama 2, in 2023. Notable open-source LLMs include Mixtral-8x7B by Mistral, Alibaba Cloud’s Qwen1.5 series, Smaug by Abacus AI, and Yi models from 01.AI, which focus on data quality.
LLMs have transformed the Natural…
Machine learning models are increasingly being used in critical applications, leading to concerns about their vulnerability to manipulation and exploitation. Once trained on a dataset, these models can retain information permanently, making them susceptible to privacy breaches, adversarial attacks, and unintended biases. There is a pressing need for techniques allowing these models to 'unlearn' specific…

In recent times, large language models (LLMs), such as Med-PaLM 2 and GPT-4, have shown impressive performance on clinical question-answer (QA) tasks. However, these models are restrictive due to their high costs, ecological unsustainability, and paid only accessibility for researchers. A promising approach is on-device AI, which uses local devices to run language models. This…
GitHub Copilot, an AI-powered coding assistant, is among several AI tools designed for developers' efficiency. Harnessing OpenAI's Codex language model, features include completing lines of code and aiding security checks.
Another similar tool is Amazon's CodeWhisperer, a machine-learning-driven code generator providing real-time coding recommendations. CodeWhisperer suggests snippets to entire functions, enhancing code quality, and automating repetitive…
Artificial intelligence (AI) has increasingly become a pivotal tool in the medical industry, assisting clinicians with tasks such as diagnosing patients, planning treatments, and staying up-to-date with the latest research. Despite this, current AI models face challenges in efficiently analyzing the wide array of medical data which includes images, videos and electronic health records (EHRs).…
