Theoretically Achieving Continuous Representation of Oriented Bounding Boxes

Considerable efforts have been devoted to Oriented Object Detection (OOD). However, one lasting issue regarding the discontinuity in Oriented Bounding Box (OBB) representation remains unresolved, which is an inherent bottleneck for extant OOD methods. This paper endeavors to completely solve this issue in a theoretically guaranteed manner and puts an end to the ad-hoc efforts in this direction. Prior studies typically can only address one of the two cases of discontinuity: rotation and aspect ratio, and often inadvertently introduce decoding discontinuity, e.g. Decoding Incompleteness (DI) and Decoding Ambiguity (DA) as discussed in literature. Specifically, we propose a novel representation method called Continuous OBB (COBB), which can be readily integrated into existing detectors e.g. Faster-RCNN as a plugin. It can theoretically ensure continuity in bounding box regression which to our best knowledge, has not been achieved in literature for rectangle-based object representation. For fairness and transparency of experiments, we have developed a modularized benchmark based on the open-source deep learning framework Jittor's detection toolbox JDet for OOD evaluation. On the popular DOTA dataset, by integrating Faster-RCNN as the same baseline model, our new method outperforms the peer method Gliding Vertex by 1.13% mAP50 (relative improvement 1.54%), and 2.46% mAP75 (relative improvement 5.91%), without any tricks.


AI in Hollywood: Crowd-created film allows fans to design generative art, work with studio on creative process

FOX News

OneDoor Studios CMO Dan Cobb discusses the adaption of the YA series'Calculated.' A Hollywood film studio is leveraging a new real-time design and artist development process to adapt a popular young adult (YA) series, including an industry-first application of artificial intelligence (AI) that gives fans and artists active input in creating character design, sets and special effects. Dan Cobb, the Chief Marketing Officer (CMO) of OneDoor Studios, said development is underway on "Calculated," an adaption of the YA sci-fi series by Nova McBee. On a mission to become the "World's First Fan-Funded and Fan-Created Film Studio," Cobb and his team have developed a relationship with AI artists on the WeGo.One's Discord channel. The artists, who are required to have deep knowledge of the source material, liaise with investors and the author to spawn images using MidJourney V5 Pro and a combination of other similar generative image technologies to build the film's storyboard, enhance concept art and develop shot lists.


ChatGPT Is Making Universities Rethink Plagiarism

WIRED

In late December of his sophomore year, Rutgers University student Kai Cobbs came to a conclusion he never thought possible: Artificial intelligence might just be dumber than humans. After listening to his peers rave about the generative AI tool ChatGPT, Cobbs decided to toy around with the chatbot while writing an essay on the history of capitalism. Best known for its ability to generate long-form written content in response to user input prompts, Cobbs expected the tool to produce a nuanced and thoughtful response to his specific research directions. Instead, his screen produced a generic, poorly written paper he'd never dare to claim as his own. "The quality of writing was appalling. The phrasing was awkward and it lacked complexity," Cobbs says.


How SMBs Can Successfully Adopt Chatbots, AI and IoT Marketing

#artificialintelligence

Maintaining digital relevance is a priority for most brands, however, according to recent research by Capterra, SMB brands are struggling in this area. The study surveyed over 700 SMB leaders, 47 percent of respondents said they factor technology trends and advancements into their strategic planning. However, choosing the right technology solution is proving to be a top business challenge, with 19 percent citing this as their number one challenge. Moreover, SMBs are failing to adopt chatbots, artificial intelligence (AI) and Internet of Things (IoT) marketing into their business strategies -- despite consumer expectations. The Capterra report identified the following three areas that SMBs are struggling to get to grips with.


Survey says: ERP changes, more human-machine interactions coming by 2030

@machinelearnbot

By 2030, a major portion of ERP-related work may be handled by machines. These systems will increase in capability as the amount of data grows and as AI advances. Human-machine interactions will play a major role in business, and well before then. The importance of human-machine interactions to business was ranked very high by the respondents participating in research by Dell Technologies and the Institute for the Future. The report is based on a survey of nearly 4,000 business leaders.


What has Mr. Robot done for the security industry?

#artificialintelligence

Yes, it's just a TV show, but television plays a huge role in creating cultural phenomenons, and Mr. Robot has certainly found its place in pop culture. Anti-hero Elliot, a hacker whose ambition is to save the world from E Corp, struggles with mental illness. The voices inside his head are constantly in a conflict of good vs evil. As a result, Elliot's good intentions have paved his road to hell. Where does that leave the rest of us, though?


Eradication of 'sudden oak death' disease is no longer possible in California

Los Angeles Times

Over the last two decades, California and the federal government have faced harsh criticism for failing to take stronger actions to stop a highly contagious disease that has killed millions of trees along coastal regions from Big Sur to portions of Oregon. Now, a new computer modeling study suggests that the "sudden oak death" epidemic, which emerged in 1995, has grown too big and is spreading too fast to eradicate statewide. The analysis is the first to integrate knowledge of the pathogen with topography, weather and resources like government budgets to predict the likely effects of various management strategies over such a large area -- in this case, California's 163,707 square miles of land. The results are somewhat hopeful: Because the epidemic's growth rate increases with its size, focusing on restoring and treating small, local forests is now the most practical and cost-effective option for managing the destructive fungus, Phtophthora ramorum. The findings were published Monday in the Proceedings of the National Academy of Sciences.
