arXiv:2406.17115v1 Announce Type: new Abstract: Despite the rapid progress and outstanding performance of Large Vision-Language Models (LVLMs) in recent years, LVLMs have been plagued by the issue of hallucination, i.e., LVLMs tend to generate responses that are inconsistent with the corresponding visual inputs. To evaluate the degree of hallucination in LVLMs, previous works have proposed a series of benchmarks featuring different types of tasks and evaluation metrics. However, we find that the quality of the existing hallucination benchmarks varies, with some suffering from problems, e.g., inconsistent evaluation results under repeated tests, and misalignment with human evaluation. To this end, we…

arXiv:2406.16937v1 Announce Type: new Abstract: The past few decades have witnessed an upsurge in data, forming the foundation for data-hungry, learning-based AI technology. Conversational agents, often referred to as AI chatbots, rely heavily on such data to train large language models (LLMs) and generate new content (knowledge) in response to user prompts. With the advent of OpenAI's ChatGPT, LLM-based chatbots have set new standards in the AI community. This paper presents a complete survey of the evolution and deployment of LLM-based chatbots in various sectors. We first summarize the development of foundational chatbots, followed by the evolution of LLMs, and…

[Submitted on 22 Jun 2024] View a PDF of the paper titled MetaGreen: Meta-Learning Inspired Transformer Selection for Green Semantic Communication, by Shubhabrata Mukherjee and 2 other authors View PDF HTML (experimental) Abstract:Semantic Communication can transform the way we transmit information, prioritizing meaningful and effective content over individual symbols or bits. This evolution promises significant benefits, including reduced latency, lower bandwidth usage, and higher throughput compared to traditional communication. However, the development of Semantic Communication faces a crucial challenge: the need for universal metrics to benchmark the joint effects of semantic information loss and energy consumption. This research introduces an…

arXiv:2406.17109v1 Announce Type: new Abstract: Leaf instance segmentation is a challenging multi-instance segmentation task, aiming to separate and delineate each leaf in an image of a plant. The delineation of each leaf is a necessary prerequisite task for several biology-related applications such as the fine-grained monitoring of plant growth, and crop yield estimation. The task is challenging because self-similarity of instances is high (similar shape and colour) and instances vary greatly in size under heavy occulusion. We believe that the key to overcoming the aforementioned challenges lies in the specific spatial patterns of leaf distribution. For example, leaves typically grow…
