Language Model

Natural Language Processing (NLP) involves computers understanding and interacting with human language through language models (LMs). These models generate responses across various tasks, making the quality assessment of responses challenging. However, as proprietary models like GPT-4 increase in sophistication, they often lack transparency, control, and affordability, thus prompting the need for reliable open-source alternatives. Existing…

Large Language Models (LLMs) have enjoyed a surge in popularity due to their excellent performance in various tasks. Recent research focuses on improving these models' accuracy using external resources including structured data and unstructured/free text. However, numerous data sources, like patient records or financial databases, contain a combination of both kinds of information. Previous chat…

Machine learning is a growing field that develops algorithms to allow computers to learn and improve performance over time. This technology has significantly impacted areas like image recognition, natural language processing, and personalized recommendations. Despite its advancements, machine learning faces challenges due to the opacity of its decision-making processes. This is especially problematic in areas…

Large Language Models (LLMs) signify a major stride in artificial intelligence with their strong natural language understanding and generation capabilities. They can perform plenty of tasks ranging from powering virtual assistants to generating substantial content and conducting profound data analysis. Nevertheless, one obstacle LLMs face is generating factually correct responses. Often, due to the wide…

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…

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…
