Adversarial attacks, efforts to deceitfully force machine learning (ML) models to make incorrect predictions, have presented a significant challenge to the safety and dependability of crucial machine learning applications. Neural networks, a form of machine learning algorithm, are especially susceptible to adversarial attacks. These attacks are especially concerning in applications such as facial recognition systems,…
Controllable Learning (CL) is being recognized as a vital element of reliable machine learning, one that ensures learning models meet set targets and can adapt to changing requirements without the need for retraining. This article examines the methods and applications of CL, focusing on its implementation within Information Retrieval (IR) systems, as demonstrated by researchers…
Retrieval-augmented generation (RAG) is a technique that enhances large language models’ capacity to handle specific expertise, offer recent data, and tune to specific domains without changing the model’s weight. RAG, however, has its difficulties. It struggles with handling different chunked contexts efficiently, often doing better with a lesser number of highly relevant contexts. Similarly, ensuring…
Advancements in Vision-and-Language Models (VLMs) like LLaVA-Med propose exciting opportunities in biomedical imaging and data analysis. Still, they also face challenges such as hallucinations and imprecision risks, potentially leading to misdiagnosis. With the escalating workload in radiology departments and professionals at risk of burnout, the need for tools to mitigate these problems is pressing.
In response…
Radiology departments often deal with massive workloads leading to burnout among radiologists. Therefore, tools to help mitigate these issues are essential. VLMs such as LLaVA-Med have advanced significantly in recent years, providing multimodal capabilities for biomedical image and data analysis. However, the generalization and user-friendliness issues of these models have hindered their clinical adoption.
To…
Large language models (LLMs) have demonstrated impressive performances across various tasks, with their reasoning capabilities playing a significant role in their development. However, the specific elements driving their improvement are not yet fully understood. Current strategies to enhance reasoning focus on enlarging model size and expanding the context length via methods such as chain of…
Large language models (LLMs) have made remarkable strides in many tasks, with their capacity to reason forming a vital aspect of their development. However, the main drivers behind these advancements remain unclear. Current measures to boost reasoning primarily involve increasing the model's size and extending the context length with methods such as the chain of…
A recent study by Innodata assessed various large language models (LLMs), including Llama2, Mistral, Gemma, and GPT for their factuality, toxicity, bias, and hallucination tendencies. The research used fourteen original datasets to evaluate the safety of these models based on their ability to generate factual, unbiased, and appropriate content. Ultimately, the study sought to help…
An in-depth study by Innodata evaluated the performance of various large language models (LLMs) including Llama2, Mistral, Gemma, and GPT. The study assessed the models based on factuality, toxicity, bias, and propensity for hallucinations and used fourteen unique datasets designed to evaluate each model's safety.
One of the main criteria was factuality, the ability of the…
Complex Human Activity Recognition (CHAR) identifies the actions and behaviors of individuals in smart environments, but the process of labeling datasets with precise temporal information of atomic activities (basic human behaviors) is difficult and can lead to errors. Moreover, in real-world scenarios, accurate and detailed labeling is hard to obtain. Addressing this challenge is important…
Recent research by scientists at Ohio State University and Carnegie Mellon University has analyzed the limitations of large language models (LLMs), such as GPT-4, and their limitations in implicit reasoning. This refers to their ability to make accurate comparisons of internalized facts and properties, even when aware of the entities in question.
The study focused…
