   I like this idea very much. Shameless plug and I don't want to be the Rust fanboy, but I've played with something similar in Rust: https://github.com/julienr/liveboard-rs Basically it uses actix for the backe

   Hey, I'm the lead engineer at Picterra. Would be happy to answer any questions. What we are trying to do is indeed allow customers to build algorithms tailored to their use cases. We often joke that the reason our ML works is because w

   I wonder if some of the classes are just easy to detect objects that they're using to assess the accuracy of the user.

   I would guess they have a system such that after a user has passed N captchas successfully, they trust its a human and start displaying them (a portion of) unlabelled captchas that will always succeed and that's when novel labelling ha

   I work at Picterra[1], a swiss company doing machine learning on drone & satellite imagery. From discussion with a number of drone service providers, it seems to me the restrictiveness really depends on the context. For things involving

    I'm not sure exactly what Netflix means by "if the job breaks", but I've used jupyter notebook in production to do ML before. If you consider the notebook as a way to augment your logs with plots, it might make a bit mor

    Those are all very good points I didn't think about, thanks for these. I'll fix the two bugs with verify_block and the possibility for a miner to inject invalid a output > input transaction. I'll add a note for the 3 other

    No good reason for RSA vs ECDSA. I was just more familiar with RSA, but apparently pycryptodome supports ECDSA as well, so I guess the change should be minimal.

    Thanks for the precision regarding the hash. Regarding the error, they are logged when a verify_block/transaction returns False, just to be a bit more explicit about what failed. In a real implementation, I guess you would throw except

    Thanks. You're right about Merkle tree. This is a whole section of the bitcoin paper and it's pretty important. But as far as I understand, it's "only" an optimization to save disk space, so it doesn't change t

    OP here. Swapping MD5 for SHA256 is very easy. I'll actually do it - see my other answer above for why MD5. For the other differences to bitcoin and from the top of my head : - In my implementation, wallet addresses are the public key

    Thanks ! I've completely left out communication from this because it wouldn't fit in the notebook and I haven't researched it. Would also appreciate if anybody has good resources on it.

    OP here. erikb is spot on in the sibling comment. This hasn't been expert-reviewed, hasn't been audited so I'm pretty confident there is a bug somewhere that I don't know about. It's educational in the sense that I

    You forgot to mention that nodes always consider the longest block chain to be the consensus. A 51% (majority) attack is when one miner is able to produce more blocks than the rest of the network, therefore controlling consensus. Such a min

    I don't know about the others, but the two visions dataset they compare to (MNIST and the face recognition one) are small datasets and the CNN they compare to doesn't seem very state of the art. It also seems each layer of random

    I built a small plugin to do that, it's called vim cell mode and provide "send selection to ipython" and "send block to ipython". I find the block mode very useful when developing data analysis scripts. https:&#x2F

    I think the jupyter devs are aware of this and trying to find a fix. There is an enhancement proposal on how to get diff to work with notebooks : https://github.com/jupyter/enhancement-proposals/blob/master...

    Open a browser and navigate to your docker container's :8888 port. That would be localhost:9990 if you used the docker commandline given in the repo.

    I stand corrected :) It seems like ILSVRC only has 2 datasets though, I wonder why they don't use a Kaggle-like approach ? My guess would be because they want people to be able to know their test score in order to put them in their pap

    They have a separate test set. But by submitting a lot of entries with slightly different parameters, you can optimize your parameters based on the test score. Some (all ? ) Kaggle competition also have a daily submission limit to avoid thi
