In response to subtle adversarial examples flipping classifications of neural network models, recent research has promoted certified robustness as a solution. There, invariance of predictions to all norm-bounded attacks is achieved through randomised smoothing of network inputs. Today's state-of-the-art certifications make optimal use of the class output scores at the input instance under test: no better radius of certification (under the L

We conduct further ablation studies for our approach in this supplementary material, including comparison with test-time optimization and sensitivity analysis of the refinement stage. Additional qualitative results are also provided. We compare our coarse-to-fine approach with the testtime optimization approach. As has been done in our coarse-to-fine pipeline, we also use the output from our coarse estimation stage as an initialization. Instead of apply the mesh refinement GCN, we further optimize the SMAL parameters based on the keypoints and silhouettes for 10, 50, 100, 200 iterations, respectively.

Supplementary Material for the Paper entitled "ABC: Auxiliary Balanced Classifier for Class-Imbalanced Semi-Supervised Learning" Figure 1 illustrates the overall procedure of consistency regularization for the ABC. Detailed procedure is described in Section 3.4 of the main paper. The pseudo code of the proposed algorithm is presented in Algorithm 1. The for loop (lines 2 14) can be run in parallel. Two types of class imbalance for the considered datasets are illustrated in Figure 2. In Figure 2 (b), we can see that each minority class has a very small amount of data. Existing SSL algorithms can be significantly biased toward majority classes under step imbalanced settings.

Robots zipping down footpaths may sound futuristic, but they are increasingly being put to work making deliveries around the world – though a legal minefield and cautious approach to new tech means they are largely absent in Australia. Retail and food businesses have been using robots for a variety of reasons, with hazard detection robots popping up in certain Woolworths stores and virtual waiters taking dishes from kitchens in understaffed restaurants to hungry diners in recent years. Overseas, in jurisdictions such as California, robots are far more visible in everyday life. Following on from the first wave of self-driving car trials in cities such as San Francisco, humans now also share footpaths with robots. Likened to lockers on wheels, companies including Serve Robotics and Coco have partnered with Uber Eats and Doordash, which have armies of robots travelling along footpaths in Los Angeles delivering takeaway meals and groceries.

Over the last decade, Dean has amassed a healthy collection of video games, from smash hits to cult classics. His digital library is like a modern day Blockbuster, all readily accessible with just a click or two. But his son, Sam, has eyes for only one video game: Roblox, the behemoth virtual universe-slash-video game that's among the most popular on the planet. The company reports that more than 97 million people log on to Roblox every day. Around 40% of those are, like Sam, under 13 years of age.

Microsoft is dramatically increasing the price of the Xbox Series X and Series S as well as new games and accessories. The Series S will start at 380, up from 300, while the Series X will begin at 550, a 100 increase on its previous price. The company is also increasing the prices of pretty much all its first-party products and peripherals. A basic controller will now cost 65. Microsoft is also increasing pricing in Europe, UK, Australia and many other countries.

Xbox prices are also rising in other countries around the world, with the Series S increasing by 80 in Europe and 50 in Australia. It represents a big change in an industry which would typically see prices go down in the years after a console's launch. "We understand that these changes are challenging," Microsoft said in a blog post. "They were made with careful consideration given market conditions and the rising cost of development." Kedhrin Gonzalez, founder of Rip & Tear studios, told the BBC he felt the price rise was "inevitable" and "catalysed by current tariff disruptions".

Bora Chung's Red Sword is set on a disputed planet While there are no big names publishing new science fiction novels this May, there are some real gems nonetheless – including a big tip from me, Grace Chan's near-future Every Version of You. I want to press it into the hands of everyone I know. There are also two fascinating sci-fi-edged thrillers out this month, by Adam Oyebanji and Barnaby Martin, while Catherine Chidgey's creepy The Book of Guilt has intrigued me enough to make it my next read – if it's not ousted by Bora Chung's real history-inspired story of war on an alien planet, Red Sword, that is… Set in late-21st-century Australia, this novel (published in Australia in 2022 but out now more widely) follows Tao-Yi in a world where most people spend their lives in an immersive virtual reality called Gaia. Every morning, she climbs into a pod in her apartment to enter Gaia, where she works and socialises. In the real world, the unrelenting heat of the sun means there are no trees left and hardly any animals: this is a terrifying vision of the future.

Netflix has started testing a new search feature powered by OpenAI that can help customers find movies and shows to watch, according to Bloomberg. The streaming service has reportedly given select users in Australia and New Zealand the option to use the tool. It will allow users to search for terms other than a specific show's title, an actor's name or the genre they want to watch. Bloomberg says it will give them a way to search for content using more specific terms, like their mood. Presumably, that means the service can surface dramatic shows for a search query that says "sad," and seeing as it's powered by generative AI, users will most likely be able to use natural language in their search terms.

In a darkened room, a fractured symphony of rattles, hums and warbles bounces off the walls – like an orchestra tuning up in some parallel universe. If you look closely there is a small fragment of a performer. In the centre of the room, visitors hover around a raised plinth, craning to glimpse the brains behind the operation. Under a magnifying lens sit two white blobs, like a tiny pair of jellyfish. Together, they form the lab-grown "mini-brain" of the late US musician Alvin Lucier – composing a posthumous score in real time.
