Enabling Quick, Accurate Crowdsourced Annotation for Elevation-Aware Flood Extent Mapping

Enabling Quick, Accurate Crowdsourced Annotation for Elevation-Aware Flood Extent Mapping

arXiv:2408.05350v1 Announce Type: new Abstract: In order to assess damage and properly allocate relief efforts, mapping the extent of flood events is a necessary and important aspect of disaster management. In recent years, deep learning methods have evolved as an effective tool to quickly label high-resolution imagery and provide necessary flood extent mappings. These methods, though, require large amounts of annotated training data to create models that are accurate and robust to new flooded imagery. In this work, we provide FloodTrace, an application that enables effective crowdsourcing for flooded region annotation for machine learning training data, removing the requirement for…

Most apartment owners in 6 big US cities are offering deals to renters — but don’t expect a break in NYC or Miami

Most apartment owners in 6 big US cities are offering deals to renters — but don’t expect a break in NYC or Miami

Apartment landlords are offering massive concessions to draw renters across the US, but not all cities are trying equally hard to drum up new tenants.In July, six metro areas — Raleigh, Charlotte, Atlanta, Salt Lake City, Nashville, and Austin — saw more than half their listings on Zillow offering rental concessions, per a Monday blog post from the online real estate marketplace. These perks ranged from free parking to a few weeks of rent-free tenancy.The surge in rental concessions comes amid increasing apartment supply after new builds were started to meet rising rents during the pandemic, wrote Skylar Olsen, Zillow's…

From Text to Insight: Leveraging Large Language Models for Performance Evaluation in Management

From Text to Insight: Leveraging Large Language Models for Performance Evaluation in Management

arXiv:2408.05328v1 Announce Type: new Abstract: This study explores the potential of Large Language Models (LLMs), specifically GPT-4, to enhance objectivity in organizational task performance evaluations. Through comparative analyses across two studies, including various task performance outputs, we demonstrate that LLMs can serve as a reliable and even superior alternative to human raters in evaluating knowledge-based performance outputs, which are a key contribution of knowledge workers. Our results suggest that GPT ratings are comparable to human ratings but exhibit higher consistency and reliability. Additionally, combined multiple GPT ratings on the same performance output show strong correlations with aggregated human performance ratings,…

#44 — Group Rows And Combine Non-Null Values in Each of The Non-Grouping Columns

#44 — Group Rows And Combine Non-Null Values in Each of The Non-Grouping Columns

Problem description & analysis: In the Excel table below, the 1st column is the category; columns from the 2nd to the 42nd are parallel columns of data items (below only shows some of the columns), where there are two types of values – X and null. Occasionally, there are duplicate values in a column under the same category. Task: Group rows and combine values in each column in each group; only display one of the duplicate values if there are any. Solution: Use SPL XLL to do this: =spl("=?.group(~1).(g=~,(r1=~1).(g.(~(r1.#)).ifn()))",A2:E11) Enter fullscreen mode Exit fullscreen mode As shown in the picture…

UK Energy Regulator Signs Off on £3.4 Billion Electricity ‘Superhighway’

UK Energy Regulator Signs Off on £3.4 Billion Electricity ‘Superhighway’

UK energy regulator Ofgem gave the green light to a £3.4 billion ($4.4 billion) funding package to build a proposed electricity “superhighway” under the North Sea.The project entails laying a 500-kilometer (311-mile) cable between Scotland and northern England to power as many as 2 million homes, the watchdog said in a statement on Tuesday. It’s the first of 26 projects in Ofgem’s fast-track funding process for offshore wind power. Source link lol

Business leaders and politicians react to Elon Musk and Donald Trump’s conversation on X

The rambling conversation, which was largely dominated by Trump in the first hour, ranged from the attempt on his life to immigration. It also started about 42 minutes behind schedule due to technical issues.Here's how prominent business and political leaders responded to the conversation.Mark Cuban Mark Cuban (left) and former President Donald Trump (right). Michael Reaves via Getty Images; Joe Raedle via Getty Images In a post on X, billionaire Mark Cuban asked: "Anyone tracking how much each participant in this Spaces "conversation" is speaking ?"The use of quotes around "conversation" appeared to reference Musk's marketing of the Space as…

China says it has an uncrewed cargo plane that can carry 4,400 pounds that just made its 20-minute maiden flight

China tested its biggest unmanned cargo aircraft to date — and it's capable of carrying 4,400 pounds of load.The plane completed its maiden flight on Sunday morning, which lasted about 20 minutes. The flight was conducted in Fengming General Aviation Airport in China's southwestern Sichuan province, according to state media CCTV.The new aircraft has a wingspan of 52.8 feet, around the width of an Olympic-sized swimming pool.CCTV wrote in its report that "it is the largest and domestically produced large-scale unmanned transport aircraft currently developed in China."Developed by state-funded drone manufacturing company Sichuan Tengden Sci-tech Innovation Co, the new aircraft…
