DRONELIFE Information of the Week June 10 - Channel969
Finest security and threat administration practices can mitigate legal responsibility publicity. Because the trade matures, and operations turn into extra advanced, now greater than ever, drone insurance coverage ought to issue closely in enterprise choices. On this article, Elad Shalev, Advertising and marketing Supervisor at SkyWatch.AI, drone trade insurance coverage leaders, offers insights into the highest three trade and accident developments, in addition to ideas to assist drone companies soar. Based in 2018, SkyWatch.AI was one of many first corporations to make use of expertise, analytics and telematics to higher assess the dangers of drone operations. That knowledge in the end knowledgeable a variety of plans to scale back threat for drone operators globally.
Can Machine Learning Translate Ancient Egyptian Texts?
I have long been intrigued by archaeogaming--an academic discipline that explores the fusion of archaeological objects, methods, and characters into video games. So I was thrilled when the video game company Ubisoft released Assassin's Creed: Origins, set in Egypt during Cleopatra's reign. The designers collaborated with Egyptologists to ensure everything from the architecture to the hieroglyphics created an accurate, immersive world. Unexpectedly, this partnership inspired a machine-learning spinoff that changed the course of my early career. While working with Egyptologists, the game developers learned that translating and interpreting ancient hieroglyphic texts is time-consuming, and the process has changed little in the last century.
Mario, Morricone or Mandalorian: what is the greatest film, TV and game music of all time?
Its fellow countdown โ run by ABC Classic โ usually does not. As its name implies, the Classic 100 is typically a more subdued affair. Unlike its boozy, bombastic cousin, the ABC's classical music station broadcasts the top 100 over multiple days. And since its inception in 2001, the annual countdown has been themed around certain genres or forms, asking listeners to vote for their favourite operas, symphonies and, one year, French compositions. This year, though, the Classic 100 might sound a little different.
Oh no... Someone trained an AI on 4chan
If you're concerned about the biases and bigotry of AI models, you're gonna love the latest addition to the ranks: a text generator trained on 4chan's /pol/ board. Short for "Politically Incorrect," /pol/ is a bastion of hate speech, conspiracy theories, and far-right extremism. These attributes attracted Yannick Kilcher, an AI whizz and YouTuber, to use /pol/ as a testing ground for bots. Kilcher first fine-tuned the GPT-J language model on over 134.5 million posts made on /pol/ across three and a half years. He then incorporated the board's thread structure into the system.
Wild Camera Designs Created by Artificial Intelligence
These cameras do not exist. As real as they might appear, they were created using an artificial intelligence system called DALL-E 2, which can make realistic images based only on text descriptions. These strange and insane-looking cameras were created using DALL-E 2, an artificial intelligence program created by OpenAI. The system was announced earlier this year and can create photo-realistic images based only on a brief description and allows a person to easily edit the image with simple tools. Not only can it create photos and images entirely from scratch, but it can also modify existing images.
Planning with Critical Section Macros: Theory and Practice
Chrpa, Lukas | Vallati, Mauro (University of Huddersfield)
Macro-operators (macros) are a well-known technique for enhancing performance of planning engines by providing "short-cuts" in the state space. Existing macro learning systems usually generate macros by considering most frequent action sequences in training plans. Unfortunately, frequent action sequences might not capture meaningful activities as a whole, leading to a limited beneficial impact for the planning process. In this paper, inspired by resource locking in critical sections in parallel computing, we propose a technique that generates macros able to capture whole activities in which limited resources (e.g., a robotic hand, or a truck) are used. Specifically, such a Critical Section macro starts by locking the resource (e.g., grabbing an object), continues by using the resource (e.g., manipulating the object) and finishes by releasing the resource (e.g., dropping the object). Hence, such a macro bridges states in which the resource is locked and cannot be used. We also introduce versions of Critical Section macros dealing with multiple resources and phased locks. Usefulness of macros is evaluated using a range of state-of-the-art planners, and a large number of benchmarks from the deterministic and learning tracks of recent editions of the International Planning Competition.
AI trained on 4chan's most hateful board is just as toxic as you'd expect
Microsoft inadvertently learned the risks of creating racist AI, but what happens if you deliberately point the intelligence at a toxic forum? As Motherboard and The Verge note, YouTuber Yannic Kilcher trained an AI language model using three years of content from 4chan's Politically Incorrect (/pol/) board, a place infamous for its racism and other forms of bigotry. After implementing the model in ten bots, Kilcher set the AI loose on the board -- and it unsurprisingly created a wave of hate. In the space of 24 hours, the bots wrote 15,000 posts that frequently included or interacted with racist content. They represented more than 10 percent of posts on /pol/ that day, Kilcher claimed. Nicknamed GPT-4chan (after OpenAI's GPT-3), the model learned to not only pick up the words used in /pol/ posts, but an overall tone that Kilcher said blended "offensiveness, nihilism, trolling and deep distrust."
Principal Components Bias in Over-parameterized Linear Models, and its Manifestation in Deep Neural Networks
Hacohen, Guy, Weinshall, Daphna
Recent work suggests that convolutional neural networks of different architectures learn to classify images in the same order. To understand this phenomenon, we revisit the over-parametrized deep linear network model. Our analysis reveals that, when the hidden layers are wide enough, the convergence rate of this model's parameters is exponentially faster along the directions of the larger principal components of the data, at a rate governed by the corresponding singular values. We term this convergence pattern the Principal Components bias (PC-bias). Empirically, we show how the PC-bias streamlines the order of learning of both linear and non-linear networks, more prominently at earlier stages of learning. We then compare our results to the simplicity bias, showing that both biases can be seen independently, and affect the order of learning in different ways. Finally, we discuss how the PC-bias may explain some benefits of early stopping and its connection to PCA, and why deep networks converge more slowly with random labels.
Social media misinformation threatens 'scientific credibility', report says
Britons' trust in science is at an all-time high after the Covid pandemic, a new report reveals โ but misinformation on social media continues to present a'threat to scientific credibility'. The 3M State of Science Index, published on Tuesday, reveals that 90 per cent of UK residents trust science in 2022, compared with 85 per cent in 2019. This stat also compares with 88 per cent of Europeans and 89 per cent of people globally who trust science in 2022. In the UK, 57 per cent of Brits say they are now more appreciative of science after the pandemic, likely due to the efforts of scientists in creating Covid vaccines. However, misinformation'is widespread' on social media and threatens the future of the public's understanding of science, the report says.
New Fiction to Help Us Reenvision Real Problems
Several of 2022's most anticipated novels offer unique perspectives on society's thorniest issues, from racism to workplace harassment. Call it a summer fiction reading list for the socially engaged. Ms. Shibata is never officially assigned the menial tasks of her workplace--making coffee, tidying, answering the phones--but since she's the only woman on staff, her colleagues expect her to oversee them. Annoyed by the tedious sexism, Shibata announces that she is pregnant and unable to continue the extra work. We follow her fake pregnancy week by week, and though there is no child, something real grows within Shibata.
