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…
OpenAI has launched a new five-level classification framework to track its progress toward achieving Artificial Intelligence (AI) that can surpass human performance, augmenting its already substantial commitment to AI safety and future improvements.
At Level 1 - "Conversational AI", AI models like ChatGPT are capable of basic interaction with people. These chatbots can understand and respond…
Stereo matching, a fundamental aspect of computer vision for nearly fifty years, involves the calculation of disparity maps from two corrected images. Its application is critical to multiple fields including autonomous driving, robotics and augmented reality. Existing surveys categorise end-to-end architectures into 2D and 3D based on cost-volume computation and optimisation methodologies. These surveys highlight…
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…
The Retrieval-Augmented Generation (RAG) pipeline is a four-step process that includes generating embeddings for queries and documents, retrieving relevant documents, analyzing the retrieved data, and generating the final answer response. Utilizing machine learning libraries like HuggingFace for generating embeddings and search engines like Elasticsearch for document retrieval, this process could be potentially cumbersome, time-consuming, and…
The Retrieval-Augmented Generation (RAG) pipeline is a complex process that involves generating embeddings for queries and documents, retrieving relevant documents, analyzing the retrieved data, and generating the final response. Each step in the pipeline requires its unique set of tools and queries, making the process intricate, time-consuming, and prone to errors.
The development of the RAG…
Large Language Models (LLMs) such as GPT-4 are highly proficient in text generation tasks including summarization and question answering. However, a common problem is their tendency to generate “hallucinations,” which refers to the production of factually incorrect or contextually irrelevant content. This problem becomes critical when it occurs despite the LLMs being given correct facts,…
Large language models (LLMs) such as GPT-4 have shown impressive capabilities in generating text for summarization and question answering tasks. But these models often “hallucinate,” or produce content that is either contextually irrelevant or factually incorrect. This is particularly concerning in applications where accuracy is crucial, such as document-based question answering and summarization, and where…
The positioning and tracking of a sensor suite within its environment is a critical element in robotics. Traditional methods known as Simultaneous Localization and Mapping (SLAM) confront issues with unsynchronized sensor data and require demanding computations, which must estimate the position at distinct time intervals, complicating the handling of unequal data from multiple sensors.
Despite…
Transformer-based Large Language Models (LLMs) like ChatGPT and LLaMA are highly effective in tasks requiring specialized knowledge and complex reasoning. However, their massive computational and storage requirements present significant challenges in wider applications. One solution to this problem is quantization, a method that converts 32-bit parameters into smaller bit sizes, which greatly improves storage efficiency…
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…
Large Language Models (LLMs) have seen substantial progress, leading researchers to focus on developing Large Vision Language Models (LVLMs), which aim to unify visual and textual data processing. However, open-source LVLMs face challenges in offering versatility comparable to proprietary models like GPT-4, Gemini Pro, and Claude 3, primarily due to limited diverse training data and…
