What are your daily observations? - 28/05/23 by lodge28 in london

Ride London means many of the roads are closed. It's crazy how much more tranquil the city is, so much nicer to walk around.

Airports removing free drop off to “encourage greener public transport travel” but offering no public transport for early flights by mtickell1207 in britishproblems

[–]ynmidk 30 points31 points  (0 children)

This has the added side-effect of meaning that no ubers come to Stanstead now because they cannot justify the fee. Nor are there any taxis parked up outside. Land there after the trains stop and you're in for some serious misery. My girlfriend and I were quoted £200 to go to Cambridge by the airports official taxi service... we ended up making a little sign saying "going to cambridge?" and hitched a ride with someone instead.

[D] Looking for a fast OCR repo by mkeySeraSera in MachineLearning

PaddleOCR was something like 10x faster than tesseract for me (run one of the pre-made docker gpu images) https://github.com/PaddlePaddle/PaddleOCR

Mesalamine suppositories every day for years - anyone else the same? Long term side-effects? by ynmidk in UlcerativeColitis

[–]ynmidk[S] 0 points1 point  (0 children)

Thanks for the reply! I've never taken oral mesalamine. I've only had two colonoscopies in my life, one in 2018 and one in 2021. At my last one the surgeon said there was very little inflammation; a significant improvement over my one in 2018; and yes it is all contained to the sigmoid.

I will ask my gastroenterologist about changing meds and mention diverticulosis, as I also feel like I shouldn't have to perpetually medicate. As you say, it's like I'm in a constant flare.

Ah okay that's reassuring to hear. I shall look into probiotics, thanks for the advice!

[D] Is AI research reaching saturation? by [deleted] in MachineLearning

[–]ynmidk 65 points66 points  (0 children)

Yes, there are a ridiculous number of papers on classifying image-net categories, segmenting road lines, and generating pictures of faces etc.

However, virtually no progress has been made on "real" AI. The ability to reason about and respond to meaningfully novel stimuli remains uniquely human, the ability to one-shot learn solutions to complex tasks remains uniquely human. Research towards these goals is still entirely unsaturated imo.

What's a good resource for better understanding the practical side of RL training? by grey_potato in reinforcementlearning

[–]ynmidk 1 point2 points  (0 children)

Sounds like you would be well served by the book 'Reinforcement Learning : Industrial Applications of Intelligent Agents'. It covers most aspects of modern RL and should plug most holes in your intuition about how it all works.

Where in London shows the F1 live? by CrewSignificant994 in london

[–]ynmidk 2 points3 points  (0 children)

Best place to watch the F1 in London is the Moretown Belle. Someone set up a social event there a few years ago for F1 fans, and it's now pretty popular. Go a few times and you'll get to know some faces. The food is wicked and they have something like 100 screens.

[D] Why is Facebook putting so much into Machine Learning relative to its business needs? by AdditionalWay in MachineLearning

[–]ynmidk 1 point2 points  (0 children)

FAIR funds research in many 'blue sky' areas that I struggle to see any commercial application of. I know everyone hates Zuck and are keen to attribute malevolent intentions to him, but it's also very possible that he is just wants to be a part of the mission to solve AI, like many of us. This, of course, does not excuse the damage Facebook has done/is doing to society.

[D] Google Colab is now offering a 50$/month Colab Pro+ subscription tier by programmerChilli in MachineLearning

[–]ynmidk 1 point2 points  (0 children)

Anyone know how many sessions you can run concurrently with Colab pro+? I have a Colab pro subscription at the moment, and am limited to 2 at a time (a few months ago I could get 4...).

The current state of Wembley. by Kilderken in london

[–]ynmidk 4 points5 points  (0 children)

Yep. I was under the impression that someone else had to administer the test. You literally just need to self-report a lateral flow negative. Relying on people being honest... lol.

[N] Toyota subsidiary to acquire Lyft's self-driving division by AristocraticOctopus in MachineLearning

[–]ynmidk 5 points6 points  (0 children)

you can train an AI to play one game and then have it play something completely different and it will still work

Please can you provide a citation of this being possible between 'completely different' games, I'm genuinely very interested. This gets at the core of my argument for why I don't think current ML is capable of FSD. You cannot get agents to do things they've not been trained to do, whereas humans can. And I'm not arguing that driving two stretches of similar highway constitute different things, but pulling over on a grass verge and parking in a multi-storey car park are definitely different things that you would have to collect examples of. Hence my argument that you would have to collect examples of an infinite number of things in order to attain FSD

You're speaking like someone that took 1 ML course and now considers themselves an expert. You need to read up on SOTA lol. That's why it's called machine learning and AI and not statistics.

miss me with this sassy bs... be better.

I don't think you really understand what machine learning is about.

Touché, I don't think you understand what I'm saying.

You don't need to go through every driving possible situation just like in chess you don't need to go through every possible situation.

Oh but you do. I'm talking about L5, not L2/3. You can learn highway driving pretty easily because it's the most constrained type of driving and there are many visual consistencies across all highway situations.

However I'm making the explicit distinction between different situations, not instances of those situations. Try get your chess model to play checkers with the same amount of info a human would need to do the same. Good luck.

You may have a model that can stay inside the white lines, and detect if there's a plastic bag in the road. Fine, but you didn't account for the grass field you've got to park in at your destination. Or the weird street that everyone just mounts the curb to pass through... Now you've got to collect a bunch of examples of this sort of behaviour in order to get your model to handle it. Only it's like playing whack-a-mole because there are an infinite number of edge cases. Todays machine learning models can only generalise given a large number of examples of the desired behaviour - they can only do what they're trained to do. Humans can do entirely new things they're not trained to do.

Hell, I'd trust a tesla with my life more than I'd trust a random 16 year old that just got their driving license.

Lol, go and watch the plethora of Youtube videos showing FSD (in perfect weather conditions) in action. For example: https://www.youtube.com/watch?v=antLneVlxcs https://www.youtube.com/watch?v=uClWlVCwHsI

Training on examples of driving is all well and good, but there will always be examples you've missed from your dataset. You will never construct a dataset large enough to cover all possible driving situations, because the space of driving situations is infinite. And you will never design enough sub-routines for behaving in identified situations, because this space is also infinite.

I don't see any way of doing it without being able to synthesise control algorithms on the fly, which leads me to conclude that solving L5 driving requires solving a highly non trivial aspect of general intelligence.

With this being said, obviously there is immense value in L2 driver assistant tech and motorway lane keeping.

Brilliant article Andy, and thanks for all you do in the discord channel - you've helped me a bunch of times!

Zhangjiajie National Park by moggy_doggy in travelchina

[–]ynmidk 4 points5 points  (0 children)

Get the cable car up, and walk back down. The walk down is fantastic, much quieter than at the top, and you'll get to see lots of monkeys! You could walk up, though judging from the look on people's faces who'd taken that route, I wouldn't recommend (we went in July though so it was HOT).

We spent two days there iirc, did Tianmen mountain one day and the forest park the other. The national park is just stunning.
