Pantone’s Colour of the Year is Giving Me the Ick

The 2025 Colour of the Year: Mocha Mousse

A Comforting Shade of Brown

Like death and taxes, the December announcement of Pantone’s Colour of the Year is one of life’s certainties. Each year, the colour authority reveals the hue set to dominate the twelve months ahead – as well as announcing a bunch of products in said shade, naturally. Last year’s colour, Peach Fuzz was a somewhat bodily affair. And so is this year’s, although this time it’s perhaps not quite as intentional.

Mocha Mousse: A Suggestion of Chocolate and Coffee

The colour Pantone has selected for 2025 is Mocha Mousse, a comforting shade of brown that "nurtures us with its suggestion of the delectable qualities of chocolate and coffee, answering our desire for comfort." But if your initial reaction to the colour was one of mild discomfort, you’re not alone. You don’t need a PHD in colour theory to see what it resembles.

Pantone’s Take on Mocha Mousse

"Underpinned by our desire for every day pleasures," says Leatrice Eiseman, executive director of the Pantone Colour Institute. "Mocha Mousse expresses a level of thoughtful indulgence. Sophisticated and lush, yet at the same time an unpretentious classic, Mocha Mousse extends our perceptions of the browns from being humble and grounded to embrace aspirational and luxe."

Mocha Mousse in Product Form

Making the VFX of Here: Crafting a Prehistoric Sequence

For filmmaker Robert Zemeckis, a good movie is the perfect blend of truth and spectacle. This combination of storytelling approaches has defined Zemeckis’ movies across the decades with fascinating results.

With his latest film, Here, visual effects studio DNEG has visualized a concept that is anchored in a fixed camera position, depicting all the action of the story. We’ve seen how AI was used to de-age Tom Hanks for Here, a film that reunites director and star of Forest Gump, one of the best VFX movies of the 90s.

Making the VFX of Here: Crafting a Prehistoric Sequence

Alexander Seaman, Visual Effects Supervisor at DNEG, begins our conversation by noting that "The sense of the challenge was very much this unique way of telling a story. Certainly, with visual effects, this is not a very common way of showcasing your narrative. At face value, it seemed like a very straightforward project: it was the type of work that we were very familiar with doing. But, once we started to get into the shots, and by that, I mean the fixed-frame camera shots, we soon realized that all of the traditional problem-solving cinematography techniques that we’re used to doing were no longer applicable."

The Hardest Shot

Here’s a fixed-position camera viewpoint seen throughout the film. However, at the conclusion, there is an exception to the film’s established aesthetic. Alexander unpacks the creation of that final shot and begins by sharing its first and only time that the camera moves in the entire movie. He explains how it happens in such a subtle transition that you don’t notice it until you’re through the move and get a sense that something was different.

Making the VFX of Here: the Hardest Shot

Of the many things that were difficult about that shot, the camera move in particular required an almost partial rebuild of even the actors. At one point, the complete set around them becomes entirely digital because the set that was built for production didn’t really cater for a camera move that did that. So, we had to work to repair the actors’ perspective, and repair where their positions were in the set.

Conclusion

Alexander Seaman’s team at DNEG has combined rethinking and recalibrating long-established digital effects approaches with the fast-emerging world of AI in the creation of environmental elements that are seen throughout the film; often to very subtle effect. In this conversation, Alexander talks through their team’s challenges and opportunities in bringing visual effects approaches into a film that showcases the idea of the long take.

FAQs

Q: What was the biggest challenge in creating the prehistoric sequence in Here?
A: The biggest challenge was that one aspect of the shot changed, and it had a knock-on effect on the thousand frames that came before or after it.

Q: How did you approach the creation of the final shot in Here?
A: We approached it like the dinosaur challenge. It required an insane amount of detail added into that shot to make it look photographic.

Q: What was the purpose of the final shot in Here?
A: The purpose was to make the audience want to find out what happened to the neighbors and other people in the neighborhood.

Q: How did you achieve the subtle visual tricks in the final shot?
A: We used a lot of small, delicate visual tricks, and an insane amount of detail to make it look photographic.

We Trust Sam Altman

The Blip: A Turbulent Chapter in OpenAI’s History

Zoë Schiffer: It really started on November 17th, this Friday afternoon when Sam Altman, the CEO of the company, gets what he says is the most surprising, shocking, and difficult news of his professional career.

The Unexpected Firing

[archival audio]: The shock dismissal of former boss, Sam Altman.

Zoë Schiffer: The board at OpenAI, which at the time was a nonprofit, has lost confidence in him, it says. Despite the fact that the company is by all measures doing incredibly well, he’s out. He’s no longer going to lead the company.

Consequences of the Firing

Michael Calore: He’s effectively fired from the company that he cofounded.

Zoë Schiffer: Yeah. That immediately sets off a chain reaction of events. His cofounder and president of the company, Greg Brockman, resigns in solidarity. Microsoft CEO Satya Nadella says that Sam Altman is actually going to join Microsoft and lead an advanced AI research team there. Then we see almost the entire employee base at OpenAI sign a letter saying, “Wait, wait, wait. If Sam leaves, we’re leaving, too.”

The Crisis Unfolds

[archival audio]: Some 500 of these 700-odd employees—

[archival audio]: … threatening to quit over the board’s abrupt firing of OpenAI’s popular CEO, Sam Altman.

The Aftermath

Zoë Schiffer: Eventually there’s this back and forth tense negotiation between Sam Altman and the board of directors, and eventually the board then installs Mira Murati, the CTO, as the interim CEO. Then shortly after that, Sam is able to reach an agreement with the board and he returns as CEO and the board looks instantly different, with Brett Taylor and Larry Summers joining, Adam D’Angelo staying, and the rest of the board leaving.

Conclusion

The events that transpired in November 2023, which came to be known as the “blip,” were a tumultuous period in OpenAI’s history. The sudden and unexpected firing of CEO Sam Altman sent shockwaves through the company, leading to a chain reaction of resignations and tensions. Ultimately, the crisis was resolved with Sam’s return as CEO, but the experience served as a reminder of the importance of effective leadership and communication within the organization.

FAQs

Q: What happened to Sam Altman after his firing?

A: Sam Altman was reinstated as CEO of OpenAI after a tense negotiation with the board of directors.

Q: What was the impact of the firing on OpenAI employees?

AI Advances Outstrip Legal Frameworks

The Need for Stronger Deterrence Against Data Theft

It’s a common belief that the law often has to play catchup with technology, and this remains apparent today as the latter continues to evolve at a fast pace. With the advent of generative artificial intelligence (Gen AI), some important legal questions still need to be addressed.

Balancing Data Protection with Innovation

Policymakers must decide how to best balance the use of data to train AI models with the need to protect the rights of creators, said Jeth Lee, chief legal officer for Microsoft Singapore. Choosing one extreme can stifle or kill innovation in AI, but it’s also not possible to allow free-for-all access to all content and data, Lee said.

Legal Questions Surrounding Gen AI

There are legal questions that need to be resolved regarding whether data generated from Gen AI tools have IP (intellectual property) rights, he said. And if they do, who owns those rights? For instance, is there sufficient creativity in content made from the use of a Gen AI application to warrant IP rights for the user or should the Gen AI tool have rights to it?

Assuming Responsibility for Legal Risks

Until these issues are addressed, AI players such as Google, OpenAI, and Microsoft have pledged to assume responsibility for the potential legal risks, should customers of their Gen AI products be challenged on copyright grounds. Google’s training data indemnity, for instance, "covers any allegations" that the tech vendor’s use of training data to create its generative models, which is used in a Gen AI service, infringes on a third-party’s IP rights.

Common Concerns about AI

Organizations are concerned about how to address copyright challenges related to the use of Gen AI as well as data protection, Lee said. Organizations want to know where their data flows to across the AI systems, how to protect this data, and who should be responsible when there is a breach, such as when an AI system malfunctions.

Need for Stronger Deterrence Against Data Theft

In Singapore, meanwhile, there are suggestions that new legislation in other areas may provide stronger deterrence against data theft and offer clear recourse for victims. Organizations that experience data theft in the Asian market typically turn to civil claims for breach of confidence as recourse, said a spokesperson from law firm Baker McKenzie Wong & Leow.

Trade Secrets Laws

The law firm believes it may be time for Singapore to consider whether such legislation is appropriate; many other countries have equivalent statutes in place. Markets that have enacted trade secrets laws include Germany, Japan, China, and the US.

Case Study: Genk Capital

One organization, Genk Capital, agrees. The Singapore-based trading firm filed a civil and criminal suit against a former employee for copying Genk’s proprietary data before leaving the company to join a competitor. The employee was found to have copied data that included trading strategy, client details, and transactions.

Conclusion

The case suggests the need for specific legislation to address trade secrets theft with criminal penalties, Koh said, adding that this would benefit especially small and midsize businesses that may lack resources to prevent such theft. Having trade-secrets specific legislation is not a novel concept, and many neighboring countries have such statutes.

FAQs

Q: What are the legal questions surrounding Gen AI?
A: There are legal questions regarding whether data generated from Gen AI tools have IP (intellectual property) rights and who owns those rights.

Q: What is Google’s training data indemnity?
A: Google’s training data indemnity "covers any allegations" that the tech vendor’s use of training data to create its generative models, which is used in a Gen AI service, infringes on a third-party’s IP rights.

Q: What are the common concerns about AI?
A: Organizations are concerned about how to address copyright challenges related to the use of Gen AI as well as data protection.

Q: Why is there a need for stronger deterrence against data theft?
A: There is a need for stronger deterrence against data theft to provide clear recourse for victims and to send a clear message that such misdeeds should not be condoned.

Unlocking RNNs: Visualizing Memorization

Unlocking RNNs: Visualizing Memorization

Memorization in Recurrent Neural Networks (RNNs)

Memorization in recurrent neural networks (RNNs) continues to pose a challenge in many applications. RNNs are designed to store information over many timesteps and retrieve it when it becomes relevant, but vanilla RNNs often struggle to do this.

Several network architectures have been proposed to tackle this problem, including Long-Short-Term Memory (LSTM) units and Gated Recurrent Units (GRU). However, the practical problem of memorization remains a challenge.

Comparing Recurrent Units

Comparing different recurrent units is often more involved than simply comparing accuracy or cross-entropy loss. High-level quantitative measures can have many explanations and may only reflect small improvements in predictions that require short-term memorization, while long-term memorization is often of interest.

A problem for qualitative analysis is needed that has a human-interpretable output and depends on both long-term and short-term contextual understanding. The typical problems used, such as Penn Treebank, Chinese Poetry Generation, or text8 generation, do not have outputs that are easy to reason about, as they require an extensive understanding of grammar, Chinese poetry, or only output a single letter.

Autocomplete Problem

To this end, this article studies the autocomplete problem. Each character is mapped to a target that represents the entire word. The space leading up to the word should also map to that target. This prediction based on the space character is particularly useful for showing contextual understanding.

The autocomplete problem is similar to the text8 generation problem: the only difference is that instead of predicting the next letter, the model predicts an entire word. This makes the output much more interpretable. Finally, because of its close relation to text8 generation, existing literature on text8 generation is relevant and comparable, as models that work well on text8 generation should work well on the autocomplete problem.

Connectivity in the Autocomplete Problem

The recently published Nested LSTM paper qualitatively compared their Nested LSTM unit to other recurrent units, showing how it memorizes in comparison, by visualizing individual cell activations. This visualization was inspired by Karpathy et al. [1], where they identify cells that capture a specific feature. However, this visualization approach works well for identifying specific features but not for capturing the long-term contextual understanding that is essential for the autocomplete problem.

Conclusion

In this article, a qualitative visualization method for comparing recurrent units with regards to memorization and contextual understanding is presented. The method is applied to the three recurrent units mentioned above: Nested LSTMs, LSTMs, and GRUs.

FAQs

Q: What is the purpose of this article?
A: The purpose of this article is to demonstrate a visualization technique that can better highlight the differences between recurrent units with regards to memorization and contextual understanding.

Q: What is the autocomplete problem?
A: The autocomplete problem is a problem where the model predicts an entire word based on the characters leading up to it, which is especially useful for showing contextual understanding.

Q: What is the difference between LSTMs and GRUs?
A: LSTMs (Long Short-Term Memory) and GRUs (Gated Recurrent Units) are both types of recurrent neural networks, but they differ in how they handle the vanishing gradient problem. LSTMs use an internal memory cell to store information, while GRUs use a gating mechanism to control the flow of information.

Q: What is the Nested LSTM unit?
A: The Nested LSTM unit is a type of LSTM unit that uses another LSTM unit to update its internal memory state, allowing for more long-term memorization.
