The visual world is richly adorned with texture, which can serve to delineate important elements of natural scenes. In anesthetized macaque monkeys, selectivity for the statistical features of natural texture is weak in V1, but substantial in V2, suggesting that neuronal activity in V2 might directly support texture perception. To test this, we investigated the relation between single cell activity in macaque V1 and V2 and simultaneously measured behavioral judgments of texture. We generated stimuli along a continuum between naturalistic texture and phase-randomized noise and trained two macaque monkeys to judge whether a sample texture more closely resembled one or the other extreme. Analysis of responses revealed that individual V1 and V2 neurons carried much less information about texture naturalness than behavioral reports. However, the sensitivity of V2 neurons, especially those preferring naturalistic textures, was significantly closer to that of behavior compared with V1. The firing of both V1 and V2 neurons predicted perceptual choices in response to repeated presentations of the same ambiguous stimulus in one monkey, despite low individual neural sensitivity. However, neither population predicted choice in the second monkey. We conclude that neural responses supporting texture perception likely continue to develop downstream of V2. Further, combined with neural data recorded while the same two monkeys performed an orientation discrimination task, our results demonstrate that choice-correlated neural activity in early sensory cortex is unstable across observers and tasks, untethered from neuronal sensitivity, and therefore unlikely to directly reflect the formation of perceptual decisions.

Starting SPB 23.1, Allegro X APD lets you import/export the symbol and component properties by using Die Text-In/Out wizards. 

Exporting the symbol 

You can export the symbol by using File > Export > Die Text-Out Wizard. 

In the Die Text-Out Wizard window, you can see the newly added options, that is, Component Properties and Symbol Properties. 

This entire information including the properties will be saved in a text file. 

Importing the symbol 

You can import the same text file in Allegro X APD by using Die Text-In Wizard. 

Choose the text file you want to import. 

Symbol properties added in the text file will be visible in the Die Text-In Wizard window. 

Hello, I was wondering how can I create variable fields in the layout.

To start, I have a template for some type of designs, and I would like that one of the texts on the silkscreen changes accordingly to an external variable, like the folder name, or a text file in the same folder.

I was thinking something similar to a page frame that changes the date automatically. How can I generate that type of fields?

If you use Chrome on your iPhone, you’re about to see some features sliding over from the Android version. Google Lens will let you add text to your image searches, and you can save files and pictures directly to Google Drive and Photos. You can get “Shopping Insights” for products you’re browsing.

Chrome for iOS now lets you add words to your Google Lens visual searches, allowing you to add nuance to your query or “perform more complex and specific searches,” as Chrome Product Manager Katia Muradyan wrote in a blog post. After activating Lens by tapping the camera icon in the Chrome search bar, you can ask questions about the object you’re snapping a pic of, and it will produce corresponding results. Google says AI Overviews will also appear for some of these search results.

The feature shares some common ground with an Apple Intelligence feature for iPhone 16 owners in iOS 18.2, which is currently in beta. Visual Intelligence lets you point your camera at something and get info about it, including asking ChatGPT questions about it or searching for it on Google.

Chrome for iPhone now has a feature that lets you save a file directly to Google Drive or Google Photos, sparing you from using your phone’s internal storage. When saving files from Chrome, you’ll see a new option to save the file to Drive. Similarly, when browsing a photo you want to save, long-press on it, and you’ll see a new “Save in Google Photos” option in the context menu. Of course, the feature requires you to be signed into a Google account.

Chrome for iOS also adds a feature that pops up a mini-map when you click on an address. Look for an underlined link to specific addresses; clicking on it will take you to the mini-map without leaving the browser.

Finally, Google is adding Shopping Insights for US users. The company frames it as a way to help you find great prices on items you’re shopping for, but it’s hard to imagine this feature exists strictly from the kindness of Google's heart. Regardless, you’ll soon see a “Good Deal Now” alert in Chrome’s address bar when browsing for products for which it’s available. You’ll see details like price history / tracking and buying options if you tap it.

The FBI is investigating a spate of racist text messages targeting Black Americans in the wake of Donald Trump’s election victory last week. The texts were reported in states including Alabama, North Carolina, Pennsylvania and Virginia, addressing recipients as young as 13 by name and telling them they were “selected to pick cotton at the nearest plantation” and other messages referencing slavery. For more, we speak with Robert Greene II, a history professor at Claflin University, South Carolina’s first and oldest historically Black university in Orangeburg, where many students were targeted. “Initially when I heard about the texts, I thought it was a bit of a hoax, but … it quickly became clear that this wasn’t just a Claflin problem, it was a national issue, as well,” says Greene. We also speak with Wisdom Cole, senior national director of advocacy for the NAACP, who says “this is only the beginning,” with a second Trump administration expected to attack civil rights and embolden hate groups.

As the number of highly capable large language models (LLMs) released continues to quickly increase, I added the ability to test new models when they become available in the Ask Luke conversational interface on this site.

For context there's a number of places in the Ask Luke pipeline that make use of AI models to transform, clean, embed, retrieve, generate content and more. I put together a short video that explains how this pipeline is constructed and why if you're interested.

Specifically for the content generation step, once the right content is found, ranked, and assembled into a set of instructions, I can select which large language model to send these instructions to. Every model gets the same instructions unless they can support a larger context window. In which case they might get more ranked results than a model with a smaller context size.

Despite the consistent instructions, switching LLMs can have a very big impact on answer generation. I'll leave you to guess which of these two answers is powered by OpenAI's GPT-4 and which one comes from Antrhopic's new (this week) Claude 3.5 Sonnet.

Some of you might astutely point out that the instruction set could be altered in specific ways when changing models. Recently, we've found the most advanced LLMs to be more interchangeable than before. But there's still differences in how they generate content as you can clearly see in the example above. Which one is best though... could soon be a matter of personal preference.
