Review for NeurIPS paper: Color Visual Illusions: A Statistics-based Computational Model

Neural Information Processing Systems

Relation to Prior Work: On the one hand, the current text is too focused on the contributions of Purves et al. Fantastic papers of Purves et al. are very inspiring, but similar ideas were suggested before and this has to be acknowledged. Specifically, Horace Barlow proposed that matching the sensors to the statistics of the stimuli in order to reduce redundancy in the response (using a sort of linear ICA) could lead to visual illusions [Barlow90]. More generally, redundancy reduction or information maximization is connected to (nonlinear) Gaussianization and uniformization transforms. Therefore, more recent uniformization techniques such as Sequential Principal Curves Analysis (SPCA) have been proposed to explain the emergence of illusions when environment is changed [Lapàrra15]. Nonlinear transforms for error minimization [Twer01,McLeod03] may also be achieved by SPCA, thus giving alternative statistical explanation for illusions [Laparra15].


Reviews: Synthesizing the preferred inputs for neurons in neural networks via deep generator networks

Neural Information Processing Systems

Visual quality of preferred inputs obtained using the proposed method is significantly improved compared to existing methods. Generalizability of the method is also supported by extra experiments. Overall the paper should be interesting to the deep learning community. However, there're also many key questions left untouched. For example, is visual interpretability a sufficient and necessary condition for good network performance?


The Outdated Tests Far Too Many Schools Still Use to Judge a Kid's Ability

Slate

This story about intelligence testing in schools was produced by the Hechinger Report, a nonprofit, independent news organization focused on inequality and innovation in education. Even before her son started kindergarten, Ashley Meier Barlow realized that she might have to fight for his education. Her son has Down syndrome; when he was in prekindergarten, school officials in Fort Thomas, Kentucky, told Barlow that he wouldn't be going to the neighborhood school, with some special education accommodations, as she had assumed. Instead, the educators told Barlow that they wanted her son to attend a classroom across town meant for children who are profoundly impacted by their disabilities. Barlow immediately resisted because she knew the curriculum would likely focus on life skills, and her son might never be taught much reading beyond learning the shape of common, functional words like stop and exit.


On Suspicious Coincidences and Pointwise Mutual Information

Williams, Christopher K. I.

arXiv.org Artificial Intelligence

Barlow (1985) hypothesized that the co-occurrence of two events $A$ and $B$ is "suspicious" if $P(A,B) \gg P(A) P(B)$. We first review classical measures of association for $2 \times 2$ contingency tables, including Yule's $Y$ (Yule, 1912), which depends only on the odds ratio $\lambda$, and is independent of the marginal probabilities of the table. We then discuss the mutual information (MI) and pointwise mutual information (PMI), which depend on the ratio $P(A,B)/P(A)P(B)$, as measures of association. We show that, once the effect of the marginals is removed, MI and PMI behave similarly to $Y$ as functions of $\lambda$. The pointwise mutual information is used extensively in some research communities for flagging suspicious coincidences, but it is important to bear in mind the sensitivity of the PMI to the marginals, with increased scores for sparser events.


Brazil picked as 2022 World Cup winners by Alan Turing Institute model

New Scientist

Brazil is the most likely winner of the 2022 football World Cup according to a prediction model from the Alan Turing Institute in London. The publicly accessible model gives Brazil a 1-in-4 chance, with England's chances put at less than 1 in 10. Many people, from bookies to bankers, have run models trying to predict the winner and losers of the men's football 2022 World Cup in Qatar, but most of these models are run behind closed doors. Nick Barlow at the Alan Turing Institute and his colleagues have developed a model that people can run on their laptops at home, with 1000 tournament run-throughs taking 15 minutes on an average laptop. "It's quite important to us for most of the things we do that we make them open source," says Barlow. "We encourage people to get involved, to use our code and to contribute to it."


'Unlike anything you've ever played': Immortality, the video game that's actually three movies

The Guardian

Every now and then you play a video game that you just cannot stop thinking about. Candy Crush might leave colourful imprints on the back of your eyelids. And then, very occasionally, a game comes along that is so entirely unlike anything you've ever played that it becomes an obsession. Immortality, the latest from lauded game-maker Sam Barlow and his studio Half Mermaid, is one of those. It is something that has never existed before: a video game that is also three feature-length films, wrapped around a mystery so compelling that I couldn't concentrate on anything else for days. It is so delicate and complex that it's difficult to figure out how it even works.


The cognitive dissonance of watching the end of Roe unfold online

MIT Technology Review

"This is it," said SCOTUSblog media editor Katie Barlow on TikTok, posting live from outside the court. Barlow was one of the few correspondents on camera the moment the opinion was released. She was silent for a few seconds, glancing down at her phone, nodding, before looking up again and succinctly announcing the crux of it: "The Constitution does not confer a right to abortion." A reader on TikTok commented that it was hard to watch live as Barlow silently read the opinion, "to see the reality of the decision wash over you," adding: "Thank you for your work." It was a fitting way to enter the official post-Roe age: on platforms that can feel so personal to their publics, even as history unfolds.


E3 2021: 20 games to watch

The Guardian

The chaotic mini-game series is making a really welcome return, this time featuring two-player co-op. The new vignette challenges range from avoiding bird plops to tweaking someone's nipple hair. The first 2D adventure for Samus in a long time, and a game that's been on Nintendo's to-do list for 15 years. Set after the events of Metroid Fusion, the game pits you against invulnerable EMMI robots that can only be beaten with stealth and strategy and new tech including the Phantom Cloak, which offers timed invisibility. Nintendo showed a luscious new trailer for its big sequel, revealing how Link will now be able to explore floating sky islands as well as a larger version of the Hyrule landscape.


The environmental impact of a PlayStation 4

#artificialintelligence

Just behind us, a giant industrial magnet powered up with warning signs dotted about its perimeter so we wouldn't scramble our phones. Before long, John Durrell, a specialist in superconductor engineering (who took apart more machines as a teenager than he can remember), arrived with a set of tools in his hands and a glint in his eye.


Telling Lies review – endless possibilities in brilliant detective story

The Guardian

Suspense, plot and character have long been considered the foundations of a good thriller – but really, the sign of a mystery done well is a sound. It's the "hwwwwahhh!" of air whooshing past your lips and down into your lungs after a pivotal reveal. It's a noise certain to be heard during the hours spent untangling the secret at the heart of Telling Lies. Sam Barlow's critically acclaimed Her Story (2015) introduced us to the concept of the interactive search engine thriller. In that game, you play an unnamed character who, for reasons unknown, is sitting at a computer trawling through hours of stolen police station video footage showing a suspect being interviewed.
