snrji··on Shareable Jupyter Notebooks That Run on Free Cloud GPUs
With which option! I have used Colab myself and I don't see live editing. I would like to see the cursor of the collaborators in real time while they edit. Also, the option to share the runtime.
snrji··on Shareable Jupyter Notebooks That Run on Free Cloud GPUs
Does anyone now if this system supports Google Docs-like live editing? I'm struggling to find such a service.
snrji··on Ask HN: Will getting a PhD lead to a more interesting life?
Not necessarily, it depends on the advisor, university, program and field.

The problem is that once you start you are committed for 4 years. Abandoning a PhD program and starting another one is quite more complicated than changing of job.

snrji··on Starship Update
SpaceX always beats my expectations, unlike Tesla.
snrji··on Ask HN: Is there a library for creating cross-editor plugins?
Hey! I didn't see your answer. That's very useful, thanks!
snrji··on Bike crash left Spokane man unconscious, so his Apple Watch called 911
It's not only about the odds, but the expected return. That's the whole point of insurance, for instance. Having an accident under these circumstances is quite improbable, but in case it happened, the return would be massive. Actually, since it might be a matter of life or death, perhaps it doesn't even make sense to think about the expected utility, because it would be infinite.
snrji··on Is the era of the $100 graphing calculator coming to an end?
For studying it would be fine, but for taking exams no way the instructors can let you in with your phone.
snrji··on Python proposal: add immutable (persistent) dictionaries
That depends on the language.
snrji··on Python proposal: add immutable (persistent) dictionaries
This is the kind of ad-hoc PEP proposal that could be completely avoidable if there was a generic modifier or initialization/declaration construction for declaring a variable as constant. So incredibly simple, so incredibly useful that it's hard to believe that it hasn't been accepted yet (it was proposed).
snrji··on Ask HN: Will I be able to talk to a human if I move from Google to Apple?
I see, thanks for warning me.
snrji··on Benefits of talking to strangers
I do it all the time... on Twitter and Reddit.

In real life I would never even look at eyes of a stranger.

Probably some people here can relate.

snrji··on Introduction to Genetic Algorithms
When I was in college I was mystified by genetic algorithms, without knowing much about them. After taking 2 subjects on the matter and reading some books, I came to the conclusion that apart from being inherently inefficient (that's what you apply them when you have no alternative), they are actually outperformed by hill climbing (which can be seen as a particular case of the former if population = 1). Also, the crossover operator seems to make more harm than good, and it's not fully understood it's usefulness in nature, although there are some theories (this last point is taken from Pedro Domingos book).
snrji··on TensorNetwork: Open-Source Library for Efficient Tensor Calculations
AFAIK TensorFlow is not Tensorflow but "Matrixflow". This library is truly tensor-based if I understood it correctly?

I found useful the diagrammatic notation, by the way.

snrji··on Apple is now a privacy-as-a-service company
This headline is pure propaganda.
snrji··on Autism research on single neurons suggests signaling problems in brain circuits
Since always. What is it otherwise?
snrji··on Building a Silicon Brain
I know, but isn't that what the OP was asking for? Isn't that an inherent tradeoff? Or: isn't that what Neuromorphic hardware and deep learning are about (ie. composing many relatively simple functions without complex branching/logic)?
snrji··on Reform capitalism or face revolution
Contrary to the belief of progressive billionaires, I think the reform of capitalism will come in form of local "soft socialism". Localism just makes sense and can be accepted by both left and right-wing people.
snrji··on Building a Silicon Brain
And why not the GPUs themselves? Which inherent limitations do they have? Aren't they essentially general purpose parallel devices?
snrji··on OpenAI releases larger GPT-2 model
Tangentially, is there any estimation of the amount of words/sentences that a kid may have heard by the time he or she learns to talk?
snrji··on PyTorch adds new dev tools
Pytorch is amazing and Facebook's open source contributions to AI are great.

However, tooling for deep learning in general is not ready for industry grade technology. Many bugs could be prevented by dependent types, but compilers are not there. Also, debugging models feels like alchemy and random changes until it works. In addition, in production systems, rigorous testing is not a standard. The closest thing I have heard of is Tesla's data engine and AI system, they do have unit tests and a shadow mode. Of course big companies will have similar technologies for critical systems, but it's not as standardized as testing in software engineering.

snrji··on Survey of Dropout Methods for Deep Neural Networks
For linear models it can be shown to be equivalent to weight decay. For nonlinear ones, it empirically behaves as a regularizer.,
snrji··on Ask HN: Is Tesla actually using customer data for training?
Thank you very much for your explanation! That's exactly what I was asking for.
snrji··on A Recipe for Training Neural Networks
By "eval" you can also mean the training subset. As I understood is at the code to evaluate the network at a given point with a given dataset. For instance, after epoch epoch, the model is evaluated for both training and validation (you see both losses)

As you said, the test subset should only be used at the very last.

snrji··on Ask HN: Will there ever be a resurgence of interest in symbolic AI?
People tend to do a hard distinction between symbolic AI and machine learning, but actually some machine learning algorithms are based on symbols (eg. decision trees and association rules build logical rules). I recommend Pedro Domingos book, The master algorithm, in which he describes the "5 machine learning tribes" (one of them is referred as "the symbolists") and advocates for a unification of different machine learning algorithms. He even proposes a particular instance of algorithm that would fulfill these criteria: Markov logic networks. He has developed an implementation, called Alchemy (https://alchemy.cs.washington.edu/).

If by symbolic AI we mean GOFAI, expert systems etc, I don't think that there will be ever a resurgence. But if by symbolic AI we mean machine learning algorithms that are somehow based on symbolic reasoning, I do think that there will be a resurgence. In particular, this resurgence will start when: a) Deep learning arrives to its limit (ie. research gets stuck) and/or b) Someone finds a scalable and SOTA-ish way to integrate symbols into gradient based algorithms.

snrji··on Types will be part of Ruby 3 stdlib source
It was not mainstream back then.

I agree that most popular dynamic are quite terrible. But, honestly, I think the real problem is not the particular implementations, but the whole idea of dynamic typing. At first it did make sense, but now that compiler writers have figured out "cheap" and general type inference, I don't see the point anymore.

However, I use Python on a daily basis because I have no decent alternative for the libraries I use.

snrji··on Types will be part of Ruby 3 stdlib source
The trend of adding type annotations to dynamically typed languages is now unstoppable. I wonder if some more exotic features (eg. side effects handling, monads or dependent types) will ever become mainstream in the feature.
snrji··on The infamous “AI gaydar” study was repeated – couln't be reproduced
I assume in both cases the dataset was balanced. Otherwise metrics such as accuracy can be meaningless.
snrji··on Languages I want to write
Noob question: don't dependent typing requires the language to be dynamic? How do you check dependencies in types otherwise (eg. the size of an array)?
snrji··on Sorting in Japanese – An Unsolved Problem (2011)
Couldn't disagree more. As you said, people do deserve protection, but who do you think that you are protecting when you protect languages? Exactly, when you protect a language you are protecting people who speak it. If you want to get rid of your native language, fine, but do not force other people to do so.

It's time for massive M&As.
