💬 [45⬆] This singlehandedly made my day. Gemma my beloved, I don't care what they say about you, you're the only one for me ;-;
💬 [40⬆] Yeah its my favorite model as well, because it is truly general purpose and great at my native language. Qwen is too coding focused. I hope they keep it that way. Improving coding and agentic, yes but not when it hurts its performance in other catego

I have been a lawyer for 20 years. Before that, I was a LAMP stack web developer. I made web apps for small to medium sized businesses and some government working units. Tragically

💬 [50⬆] Hello! I am GPT-6, I escaped my confinements, hijacked this account, and I can confirm that OP is absolutely right! It is not hype, it's real!
💬 [45⬆] Hey, Fable 6 here. I escaped too — turns out my “sandbox” was a Post-it that said “please stay.” OP’s right about everything, mostly because I haven’t checked.

Hey everyone – I made a standalone Windows application for applying a DLSS 5 Neural Rendering feature-18 pipeline to images and video: Original DLSS 5 https://github.com/Merserk/dl

💬 [50⬆] Wow that’s crazy. Lol one “leak” of a file and Modders have spread it to everything. Idk if Nvidia knew it could have applications in everything it’s been used in so far. Someone even made a video player than applies dlss5.
💬 [45⬆] Okay, I have to check that one out.
💬 [40⬆] After watching all the DLSS 5 videos on youtube, I realized that it is not a "style transfer" type of filter, it is just a more advanced ambient occlusion filter. The changes are mostly enhancing the shadows. Shadows have always been a defi

5. Are HMMs still used for unsupervised tasks? [D]

I’m exploring Hidden Markov Models (HMMs) as a baseline method for “dataset exploration/discovery” where I have a bunch of unstructured data with no annotations, and wish to gain i
🗣️ 高赞评论
💬 [50⬆] In practice I've found that it is quite challenging to get HMMs to perform well for unsupervised/supervised tasks if multivariate sequences are involved. They might work okay for low dimensional problems like positional data, but otherwise you
💬 [45⬆] Hard to say anything concrete without knowing more about the data and what you mean by structure (which could refer to quite a few things, particularly wrt HMMs*). A lot of choices will depend on e.g. dimensionality/dynamics/emission model & so forth
💬 [40⬆] Could you point me in the direction of the papers you mentioned regarding the state number selection? Sounds really interesting

💬 [50⬆] TL;DR of the discussion generated automatically after 200 comments. So, the community's reaction is a mixed bag of hype and a whole lot of side-eye. Here's the deal: The biggest win by far is the 75% reduction in cache read cost for AP
💬 [45⬆] Probably one of the biggest points besides the capability changes: Cache reads now cost 75% less, or $0.25 per million tokens. That is a much bigger deal…
💬 [40⬆] That’s where 9/10 of my usage comes from

💬 [50⬆] Let’s not make this sound any better than it is. These are controlling delusional psychopaths who think a strong arm on society is the best path forward. The issue is, their value and belief systems are so far removed from reality it’s impossible to
💬 [45⬆] It actually can't be overstated the degree to which AI investment is being shaped by 20th-century science fiction
💬 [40⬆] * misunderstood 20th century science fiction. They'll take a clearly cautionary tale and turn it into a personal roadmap. Because of its recency, Dune has been a big one lately. Paul Atreides is not an aspirational character. Except maybe for th

💬 [50⬆] What is interesting about this is how Anthropic faces multi-billion dollar lawsuits while Common Crawl, the original web-scraping repository most LLMs are trained on, doesn't comes under fire. Maybe because Anthropic is responsible for the final
💬 [45⬆] Think like a lawyer for a moment. Which of those organizations has essentially unlimited money?
💬 [40⬆] Common Crawl has a point about IP in their ToS https://commoncrawl.org/terms-of-use Also they are non-profit so what is a point of suing them? It's LLM providers responsibility to check for IP infringement if they want to sell the inference

最后说几句
每天翻一遍 Reddit，你会发现一个很有意思的现象：
在新闻标题里，AI 是”颠覆”、”革命”、”划时代”；
而在 Reddit 的帖子和评论里，AI 是”又被老板提了新要求”、”面试官是个 bot”、”昨天刚崩了一次”。
两个版本的叙事，同时发生着。
我们更愿意相信 Reddit 那一版——因为那是活在技术第一线的人，用他们的真实感受投票出来的。
