Learning Lens Blur Fields

news.ycombinator.com Unknown 2025-09-29 00:21:27

Lens blur field shown in step 2 is from the dual pixels of a Pixel 4a. Abstract Optical blur is an inherent property of any lens system and is challenging to model in modern cameras because of their complex optical elements. To tackle this challenge, we introduce a high‑dimensional neural representation of blur—the lens blur field—and a practical method for acquisition. The lens blur field is a multilayer perceptron (MLP) designed to (1) accurately capture variations of the lens 2‑D point sprea

Language Models Pack Billions of Concepts into 12,000 Dimensions

news.ycombinator.com Unknown 2025-10-02 15:54:20

In a recent 3Blue1Brown video series on transformer models, Grant Sanderson posed a fascinating question: How can a relatively modest embedding space of 12,288 dimensions (GPT-3) accommodate millions of distinct real-world concepts? The answer lies at the intersection of high-dimensional geometry and a remarkable mathematical result known as the Johnson-Lindenstrauss lemma. While exploring this question, I discovered something unexpected that led to an interesting collaboration with Grant and a

My thoughts on renting versus buying

news.ycombinator.com Miles Barr 2025-10-02 13:36:14

I’ve read numerous articles about renting versus buying and most dive into financial projections while completely missing the bigger picture. In my view, behavioral and emotional factors have a far larger impact on the financial outcomes of renting versus buying than the math. The math can always be made to “work” if you’re willing to adjust what or where you rent or buy. But the real differences aren’t captured in spreadsheets. They come from how people actually make decisions, and how those d

Eye drops could replace glasses or surgery for longsightedness, study says

news.ycombinator.com Andrew Gregory 2025-10-02 10:59:16

Doctors have developed special eye drops for people with longsightedness that could replace the need for reading glasses or surgery. Hundreds of millions of people worldwide have presbyopia, which is when the eyes find it difficult to focus on objects and text up close. Glasses or surgery can usually resolve the problem but many find wearing spectacles inconvenient and having an operation is not an option for everyone. Now experts say the solution could be as simple as using eye drops twice a

OCSP Service Has Reached End of Life

Eric Kripke Assures ‘The Boys’ is Still Getting a Mexico Spinoff

Prime Video’s been feeding superhero audiences with The Boys and its Gen V spinoff, but the franchise has other shows in the works. Up on the docket is one set in Mexico that’s gone quiet since the initial reveal back in 2023. But according to Boys showrunner Eric Kripke, that series remains alive and kicking.

Karen Hao on the Empire of AI, AGI evangelists, and the cost of belief

techcrunch.com Rebecca Bellan 2025-10-02 10:00:34

At the center of every empire is an ideology, a belief system that propels the system forward and justifies expansion – even if the cost of that expansion directly defies the ideology’s stated mission. For European colonial powers, it was Christianity and the promise of saving souls while extracting resources. For today’s AI empire, it’s artificial general intelligence to “benefit all humanity.” And OpenAI is its chief evangelist, spreading zeal across the industry in a way that has reframed ho

As generative AI slop is threatening to turn Hollywood on its head, not everybody in the industry is enthusiastic about the tech. In a hilarious counter to a fan's AI-generated image of actor Brandon Sklenar dressed as the DC Comics' Batman, DC Studios filmmaker and "Superman" director James Gunn quipped in a Threads post that "it would be weird to cast an AI Batman with a 14 inch arm."

OpenAI Realizes It Made a Terrible Mistake

OpenAI claims to have figured out what's driving "hallucinations," or AI models' strong tendency to make up answers that are factually incorrect. It's a major problem plaguing the entire industry, greatly undercutting the usefulness of the tech. Worse yet, experts have found that the problem is getting worse as AI models get more capable. As a result, despite incurring astronomical expenses in their deployment, frontier AI models are still prone to making inaccurate claims when faced with a pr

Feds try to dodge lawsuit against their bogus climate report

Scarlet turns Shakespeare into an animated fantasy epic

Well, I was wrong, and I did manage to make it to one last day at the Toronto International Film Festival. One of the movies I wanted to see the most this year was Scarlet, the latest from Mamoru Hosoda, whose most recent film was the metaverse fairy tale Belle. Whereas that film was a reimagining of Beauty and the Beast, Scarlet is a twist on Hamlet that’s full of bold, creative ideas. I mostly enjoyed it, but unfortunately it’s saddled with an ending that doesn’t really fit. I also managed to
