Dremio says it has dramatically improved query performance on Iceberg data lakes – SiliconANGLE

stp2y0 CommentsGenAIDremio says it has dramatically improved query performance on Iceberg data lakes, Paul Gillin, SiliconANGLE

Data lakehouse company Dremio Corp. today announced a set of advanced analytics performance capabilities that it says significantly speed query performance on Apache Iceberg tables while reducing the need for user intervention. The two major new features are Live Reflections and Result Set Caching. Dremio Reflections are a feature of the company’s data lake engine that accelerates query performance by creating optimized, precomputed data representations. They’re similar in concept to materialized views but are more flexible and integrated with Dremio’s architecture. As a result, they enable faster and more interactive querying of large datasets stored in data lakes without data…

Slack Rolls Out New Automation Features

stp2y0 CommentsGenAI

Salesforce is jumping further onto the automation bandwagon with newly announced features in Slack that make it easier for users to build features regardless of their level of technical expertise. According to an Aug. 26 press release: Slack users can now build a workflow that starts automatically when an event occurs in a third-party app such as PagerDuty, Asana, or BitBucket. Customers creating workflows in Slack can access more than 50 new plug-and-play templates of common productivity use cases. Developers have access to more coding languages and tools, so they can create custom workflows and share them with their teams.…

A team of researchers from the University of Cologne's Faculty of Medicine and University Hospital Cologne, led by Dr Yuri Tolkach and Professor Dr Reinhard Büttner, has created a digital pathology platform based on artificial intelligence. The platform uses new algorithms developed by the team and enables fully automated analysis of tissue sections from lung cancer patients. The platform makes it possible to analyse digitized tissue samples on the computer for lung tumours more quickly and accurately than before. The study 'Next generation lung cancer pathology: development and validation of diagnostic and prognostic algorithms' has been published in the journal…

Cyber Security and IT Leadership: A Growing Threat to Australia’s Renewable Energy Efforts

stp2y0 CommentsGenAI

Australia is on a mission to become a more energy-efficient nation. The Australian Renewable Energy Agency recently announced a $100 million initiative to explore and expand solar energy capabilities. Further investments in energy storage, pumped hydro, and low-carbon grids may prove just as significant. However, the nation must also address an underlying challenge: the integration of robust IT and software foundations within the OT environments that run the grids. Without these, Australia could struggle to fully realise its renewable energy ambitions. The convergence of OT and IT OT refers to the hardware and software that detects or causes changes through…

Non-living hydrogels can play the video game Pong and improve their gameplay with more experience, researchers report August 23 in the Cell Press journal Cell Reports Physical Science. The researchers hooked hydrogels up to a virtual game environment and then applied a feedback loop between the hydrogel's paddle -- encoded by the distribution of charged particles within the hydrogel -- and the ball's position -- encoded by electrical stimulation. With practice, the hydrogel's accuracy improved by up to 10%, resulting in longer rallies. The researchers say that this demonstrates the ability of non-living materials to use "memory" to update their…

The backlash against image and video synthesis is not solely focused on creative app developers. Hardware manufacturer Wacom and game publisher Wizards of the Coast have faced criticism and issued apologies after using AI-generated content in their marketing materials. Toys "R" Us also faced a negative reaction after debuting an AI-generated commercial. Companies are still grappling with balancing the potential benefits of generative AI with the ethical concerns it raises.Artists and Critics ReactSo far, Procreate’s anti-AI announcement has been met with a largely positive reaction in replies to its social media post. In a widely liked comment, artist Freya Holmér…

LLM Evaluation For Text Summarization

stp2y0 CommentsGenAI

Evaluating text summarization is difficult because there is no one correct solution, and summarization quality often depends on the summary’s context and purpose. Metrics like ROUGE, METEOR, and BLEU focus on N-gram overlap but fail to capture the semantic meaning and context. LLM-based evaluation approaches like BERTScore and G-eval aim to address these shortcomings by evaluating semantic similarity and coherence, providing a more accurate assessment. Despite these advancements and the widespread use of LLM-generated summaries, ensuring robust and comprehensive evaluation remains an open problem and active area of research. Text summarization is a prime use case of LLMs (Large Language…

Low Media Literacy: A Risk to Australia’s Cybersecurity Landscape

stp2y0 CommentsGenAI

A recent study by Western Sydney University, Adult Media Literacy in 2024, revealed worryingly low levels of media literacy among Australians, particularly given the deepfake capabilities posted by newer AI technologies. This deficiency poses an IT security risk, given that human error remains the leading cause of security breaches. As disinformation and deepfakes become increasingly sophisticated, the need for a cohesive national response is more urgent than ever, the report noted. Because AI can produce highly convincing disinformation, the risk of human error becomes magnified. Individuals who are not media literate are more likely to fall prey to such schemes,…

Beetle that pushes dung with the help of 100 billion stars unlocks the key to better navigation systems in drones and satellites

An insect species that evolved 130 million years ago is the inspiration for a new research study to improve navigation systems in drones, robots, and orbiting satellites. The dung beetle is the first known species to use the Milky Way at night to navigate, focusing on the constellation of stars as a reference point to roll balls of dung in a straight line away from their competitors. Swedish researchers made this discovery in 2013 and a decade later, Australian engineers are modelling the same technique used by the dung beetle to develop an AI sensor that can accurately measure the…
