You, Me, and My AI-Generated Alternate Identity
@azusagakuyuki is a young Japanese motorcyclist with long hair, a delicate chin, and 33,000 Twitter followers. There, she posts pictures of herself in a biker shirt, posing in front of her gleaming red-and-blue Yamaha Telkor on dirt roads and hilltops and misty beaches. She’s beautiful, adventurous, and envy-inducing. But one day, she accidentally posted a picture of her bike on Twitter that captured her reflection in the rear-view mirror. The reflection was of a middle-aged man–because the woman in the photo was actually a 50-year-old man named Soya who transformed his face using a machine-learning-powered face tune app. (To his credit, Soya’s luscious locks are 100% his own.) “No-one will read what a normal middle-aged man, taking care of his motorcycle and taking pictures outside, posts... -

An Impractical Guide to AI on Google Cloud
Your manager holds a gun to the side of your head and says, “Sell me a Google Cloud AI product in the next ten minutes or you’re toast.” It’s that time of year again. Performance reviews. Perf. “Okay, okay,” you say. “Cool it. There are so many products in the GCP AI portfolio, I’m sure we can find one to fit your use case.” “I don’t have a use case,” your manager says. “AWS said I didn’t need one.” Now you’re sweating bullets. “And if you don’t start selling me something in the next three seconds, I’m turning this thing on,” he says, patting the metal rail next to you. You’re chained to a treadmill desk. You jab your fingers into your Android-shaped stress ball and try to summon all of the GCP AI product offerings into your mind.

关于 「无麸质葡萄酒」的一些真相
本文共 2632 字 | 内容深度：★★★☆☆ 本文翻译自 Pix.wine, 作者：Felicity Carter 原文链接：https://www.pix.wine/the-drop/debunking-gluten-free-wine/ 从蹒跚学步时，贾斯汀• 霍华德-斯奈德 (Justin Howard-Sneyd) 就被一种神秘而又危及生命的疾病所困扰。“我的肚子胀得很大，但手臂却骨瘦如柴，肌肉像果冻一样轻软无力。”他说，“没有人知道问题出在哪里”。 一位儿科医生提出，麸质可能是导致他的病症的原因。通过被霍华德-斯奈德称为 "我一生中最可怕的经历之一 "的活组织检查，医生的诊断得到证实：乳糜泻 (Celiac Disease)。这是一种由麸质引发的危险的免疫紊乱。（麸质是小麦和黑麦等谷物中的一种蛋白质。）如果不加以控制，乳糜泻将损害病人的肠道。 因此，霍华德-斯奈德应该是最近涌现在货架上的无麸质葡萄酒的完美客户。比如由名人朱莉安•霍夫（Julianne Hough）和妮娜•杜波夫（Nina Dobrev）于今年早些时候创立的品牌「Fresh Vine」。杜波夫告诉《好莱坞报道》，“大多数情况下 , 葡萄酒并不是「无麸质（Gluten-free)」的，然而这一点并不为众人所知。” Justin Howard-Sneyd, MW 然而，霍华德-斯奈德其实已经喝了很多葡萄酒。这是他生活的重要一部分：他不仅是一位做过葡萄酒采购、销售和咨询的葡萄酒大师（Master of Wine），而且还在自己位于法国南部的酒庄里酿酒。 这是怎么回事？如果葡萄酒里含有麸质蛋白，他怎么能喝呢？ 麸质的问题 英国谢菲尔德大学的胃肠病学家大卫•桑德斯教授 (Professor David Sanders) 是「麸质蛋白对消化系统影响」领域的世界顶尖研究者之一。他说，虽然约有 1% 的人口患有乳... -

Build an Animal/Object Tracking Camera App with TensorFlow.js
Introducing PetCam: a non-invasive machine-learning-powered pet tracker that runs on an old smartphone. This project is a collaboration between me and Jason Mayes, who came up with the idea. Also, funny story, uh… my colleague Markku Lepistö built (almost) THE EXACT SAME PROJECT at the same time on his own YouTube show, Level Up, which you can see here. We use old smartphones. He uses a Coral development board. Choose your own adventure. When I was young and lived at home in New Jersey, my parents were really strict with me about remembering to close the garage at night. Because if I didn’t close the garage, something like this would happen: Then the next morning, we’d walk out the front door, get hit with a strong whiff of dirty diapers, and see a trash bag torn up and emptied all over ou... -

Transformers, Explained: Understand the Model Behind GPT-3, BERT, and T5
You know that expression When you have a hammer, everything looks like a nail? Well, in machine learning, it seems like we really have discovered a magical hammer for which everything is, in fact, a nail, and they’re called Transformers. Transformers are models that can be designed to translate text, write poems and op eds, and even generate computer code. In fact, lots of the amazing research I write about on daleonai.com is built on Transformers, like AlphaFold 2, the model that predicts the structures of proteins from their genetic sequences, as well as powerful natural language processing (NLP) models like GPT-3, BERT, T5, Switch, Meena, and others. You might say they’re more than meets the… ugh, forget it. If you want to stay hip in machine learning and especially NLP, you have to kno... -

How I, One Humble Engineer, Deal With Imposter Syndrome
Let me start this post off by saying that imposter syndrome has already been covered profusely and at length, and there’s probably nothing new I can add to the discussion, so let me stop here, thanks for reading, and sorry for wasting your time. Akhem. While there’s already tons of advice for overcoming imposter syndrome, I find it usually falls into one of two buckets: YOU! An imposter?! No way! Just stop thinking that! Fake it ‘til you make it. If you just keep acting confident, one day you will be. The first angle is clearly useless, and the second, I’d argue, is neither possible nor advisable. Hot take: you cannot successfully fake being confident. Not to say it wouldn’t be useful if you could. Research shows that when it comes to appearing competent, confidence is as (or more) persuas... -

AI Dubs Over Subs? Translating and Dubbing Videos with AI
Alongside cooking for myself and walking laps around the house, Japanese cartoons (or “anime” as the kids are calling it) are something I’ve learned to love during quarantine. The problem with watching anime, though, is that short of learning Japanese, you become dependent on human translators and voice actors to port the content to your language. Sometimes you get the subtitles (“subs”) but not the voicing (“dubs”). Other times, entire seasons of shows aren’t translated at all, and you’re left on the edge of your seat with only Wikipedia summaries and 90s web forums to ferry you through the darkness. So what are you supposed to do? The answer is obviously not to ask a computer to transcribe, translate, and voice-act entire episodes of a TV show from Japanese to English. Translation is a c... -

DALL·E Explained in Under 5 Minutes
It seems like every few months, someone publishes a machine learning paper or demo that makes my jaw drop. This month, it’s OpenAI’s new image-generating model, DALL·E. This behemoth 12-billion-parameter neural network takes a text caption (i.e. “an armchair in the shape of an avocado”) and generates images to match it: From https://openai.com/blog/dall-e/. I think its pictures are pretty inspiring (I’d buy one of those avocado chairs), but what’s even more impressive is DALL·E’s ability to understand and render concepts of space, time, and even logic (more on that in a second). In this post, I’ll give you a quick overview of what DALL·E can do, how it works, how it fits in with recent trends in ML, and why it’s significant. Away we go! What is DALL·E and what can it do? In July, DALL·E’s ... -

AlphaFold 2 Explained: A Semi-Deep Dive
At the end of last month, DeepMind, Google’s machine learning research branch known for building bots that beat world champions at Go and StarCraft II, hit a new benchmark: accurately predicting the structure of proteins. If their results are as good as the team claims, their model, AlphaFold, could be a major boon for both drug discovery and fundamental biological research. But how does this new neural-network-based model work? In this post, I’ll try to give you a brief but semi-deep dive behind both the machine learning and biology that power this model. First, a quick biology primer: The functions of proteins in the body are entirely defined by their three-dimensional structures. For example, it’s the notorious “spike proteins’’ which stud coronavirus that allows the virus to enter our ... -
酒号屠苏味更醇
本文共1829字 | 内容深度：★★★☆☆ 王安石的诗歌 《元日》，是大家对于古代春节习俗最为熟悉的描述：「爆竹声中一岁除，春风送暖入屠苏。千门万户曈曈日，争插新桃换旧符。」 其中「东风送暖入屠苏」句争议颇多，但最常见的理解是指共饮屠苏酒的情景。宋代李壁的 《王荆公诗注》中， 解释屠苏说：「屠，割也；苏，腐也。今医方集众药为之，除夕以浸酒悬于井中，元日取之，自少至长东面而饮。取其滓以绛囊盛，挂于门桁之上，主辟瘟疫。」 唐宋时代的诗词中，常见屠苏酒的身影，作为除夕、元日的饮品。如卢象 《赠郑虔》「书名会粹才偏逸，酒号屠苏味更醇。」 方回《丙申元日五绝 》「后饮屠苏懒奔走，可能也喜鹁鸠晴。」陆游的 《除夕》：「炽炭炉中百药香，屠苏煎酒代椒觞。」等等。 当时人们饮屠苏酒的风俗，有一特别之处，即前文所述：「自少至长东面而饮。」也就是说，阖家共饮屠苏酒时， 要席间年纪最小的先喝，而年纪越大的越要最后喝。晋人董勋在其《时镜新书》中解释说「俗以小者得岁，故先酒贺之，老者失时，故后饮酒。」每过新年，少年者成长，先饮以为庆贺；年老者韶华渐逝，所以留在最后再喝。 这样的习俗，也很容易引起人们对于时光易逝，人生短促的感怀， 苏辙的《除日》诗「年年最后饮屠苏，不觉年来七十余」，赵师侠 《鹧鸪天》词句「残蜡烛，旧桃符，宁辞末後饮屠苏」 ，方干《元日》诗中「才酌屠苏定年齿，坐中惟笑鬓毛斑」 等等皆是如此。 《容斋续笔》书影 对于屠苏酒的起源，宋人洪迈在其《容斋续笔》中考证，「今人元日饮屠酥酒，自小者起，相传已久，然固有来处。后汉李膺、杜密以党人同系狱，值元日，于狱中饮酒，曰：‘正旦从小起。’」。依据「正旦从小起」的习俗，洪迈认为东汉（即文中后汉）时就有屠苏（酥）酒了。 屠苏酒是一种使用中草药材炮制的防疫药酒，东晋葛洪的《肘后备急方》中最早出现了它的处方、炮制和饮用方法。其方曰「大黄五分，川椒五分，术、...
