ICT: Image-Object Cross-Level Trusted Intervention for Mitigating Object Hallucination in Large Vision-Language Models

arXiv.org Artificial Intelligence

Despite the recent breakthroughs achieved by Large Vision Language Models (LVLMs) in understanding and responding to complex visual-textual contexts, their inherent hallucination tendencies limit their practical application in real-world scenarios that demand high levels of precision. Existing methods typically either fine-tune the LVLMs using additional data, which incurs extra costs in manual annotation and computational resources or perform comparisons at the decoding stage, which may eliminate useful language priors for reasoning while introducing inference time overhead. Therefore, we propose ICT, a lightweight, training-free method that calculates an intervention direction to shift the model's focus towards different levels of visual information, enhancing its attention to high-level and fine-grained visual details. During the forward pass stage, the intervention is applied to the attention heads that encode the overall image information and the fine-grained object details, effectively mitigating the phenomenon of overly language priors, and thereby alleviating hallucinations. Extensive experiments demonstrate that ICT achieves strong performance with a small amount of data and generalizes well across different datasets and models. Our code will be public.


Workplace AI, robots and trackers are bad for quality of life, study finds

The Guardian

Exposure to new technologies including trackers, robots and AI-based software at work is bad for people's quality of life, according to a groundbreaking study from the the Institute for Work thinktank. Based on a survey of more than 6,000 people, the study analysed the impact on wellbeing of four groups of technologies that are becoming increasingly prevalent across the economy. The authors found that the more workers were exposed to technologies in three of these categories – software based on AI and machine learning; surveillance devices such as wearable trackers; and robotics – the worse their health and wellbeing tended to be. By contrast, use of more long-established information and communication technologies (ICTs) such as laptops, tablets and instant messaging at work tended to have a more positive effect on wellbeing. "We found that quality of life improved as the frequency of interaction with ICTs increased, whereas quality of life deteriorated as frequency of interaction with newer workplace technologies rose," the report said.


Developing and Building Ontologies in Cyber Security

arXiv.org Artificial Intelligence

Cyber Security is one of the most arising disciplines in our modern society. We work on Cybersecurity domain and in this the topic we chose is Cyber Security Ontologies. In this we gather all latest and previous ontologies and compare them on the basis of different analyzing factors to get best of them. Reason to select this topic is to assemble different ontologies from different era of time. Because, researches that included in this SLR is mostly studied single ontology. If any researcher wants to study ontologies, he has to study every single ontology and select which one is best for his research. So, we assemble different types of ontology and compare them against each other to get best of them. A total 24 papers between years 2010-2020 are carefully selected through systematic process and classified accordingly. Lastly, this SLR have been presented to provide the researchers promising future directions in the domain of cybersecurity ontologies.


Huawei Calls for Network Evolution at COP27 to Enable Green Development

#artificialintelligence

A Huawei executive said Thursday information and communications technologies, or ICT, will enable the digitalization of industry, spark innovation and make other industries green. The remarks were made at a session organized by the Global Innovation Hub (UGIH) of the United Nations Framework Convention on Climate Change (UNFCCC) at the ongoing 27th Conference of the Parties, or COP27, in Sharm El-Sheikh of Egypt. Referring to what is known as the "enabling effect", Philippe Wang, Huawei's Executive Vice President for the Northern Africa region, said ICT is "making other industries greener". "5G, Artificial Intelligence, data analytics, cloud computing – all these things will improve industrial processes in a way that cuts energy use, and lowers carbon emissions," he said. According to Philippe Wang, in the same way that ICT enables a smart streetlight to turn itself off when no one is around, 5G wireless base stations can automatically shut down when there is no data traffic, which saves energy.


WinoDict: Probing language models for in-context word acquisition

arXiv.org Artificial Intelligence

We introduce a new in-context learning paradigm to measure Large Language Models' (LLMs) ability to learn novel words during inference. In particular, we rewrite Winograd-style co-reference resolution problems by replacing the key concept word with a synthetic but plausible word that the model must understand to complete the task. Solving this task requires the model to make use of the dictionary definition of the new word given in the prompt. This benchmark addresses word acquisition, one important aspect of the diachronic degradation known to afflict LLMs. As LLMs are frozen in time at the moment they are trained, they are normally unable to reflect the way language changes over time. We show that the accuracy of LLMs compared to the original Winograd tasks decreases radically in our benchmark, thus identifying a limitation of current models and providing a benchmark to measure future improvements in LLMs ability to do in-context learning.
