2018 DS/ML digest 12

As usual, this is whatever I found really interesting / worth reading.

Implementations / papers / ideas


You can count bees well with UNet -


A really super cool idea - use affine transformations in 3D to stack augmentations on the level of transformation matrices

(3D augs are costly)


- both for rotation and scaling

- note a couple of things for easier understanding:

-- there is offset in tranformations - because the coordinate center is not in "center"

-- zoom essentially scales unit vectors after applying the offset

- 3Blue1Brown videos about linear algebra -


A top solution from Google's Landmark Challenge -


- ensemble of features / skip connections from a CNN (ResNeXt)


- use KNN + augment the extracted features by averaging with similar images

- query expansion (use the fact that different crops of the same landmark remain the same landmark)


(RU) A super cool series about interestring clustering algorithms

- Affinity propagation




- (spoiler - in practice use awesome HDBSCAN library)


Brief review of image super-resolution techniques


- In a nutshell try in this order FCN CNNs, auto-encoders with skip connections or GANs


SOTA NLP by open-ai

Key ideas

- Train a transformer language models on large corpus in an unsupervised way

- Fine-tune on a smaller task

- Profit


- "Our approach requires an expensive pre-training step - 1 month on 8 GPUs" (probably this should be discounted somewhat)

- TF and unreadable enterprise code


One more claimed SOTA word embedding set


A cool github page by Sebastian Ruder to track major NLP tasks



Amazing visual explanations of how decision trees work


- it explains visually how overfitting occurs in decisions tree models


CIFAR T-SNE can be done in real-time on the GPU + tensorflow.js integration

A note on CDNs and protecting your website against censorship



- Using a free / cheap CDN service can enable you to protect your domain hosted resource from censorship

- Unless CDN servers will be blocked (but I guess the CDN has more servers, than you, right?)

So, I host on Digital Ocean. And I do not want to move or start a CDN by myself. I read news, that Google abandoned some of its proxying tools because of such censorship events...interesting.

I knew that services like Cloudflare (**CDN**) forward your traffic somehow, but I was not sure what IP is actually seen by the user and whether all of the traffic is forwarded. Then I read their FAQ


It says

After a visitor's browser has done the initial DNS lookup, it begins making requests to retrieve the actual content of a website. These requests are directed to the IP address that was returned from the DNS lookup. Before Cloudflare, that address would have been With Cloudflare as the authoritative nameserver, the new address is Cloudflare’s data center at will serve as much of your website as it can from its local storage, and ask your web server at for any part of your website it doesn’t already have stored locally. The Cloudflare data center at will then provide your complete website to the visitor, so the visitor never talks directly to your web server at

So I tried their free-tier service (paid service starts from US$20-200, which is too steep) and it just works, though SSL certificates were issued ~90 mins after I changed my nameservers. It is as easy as:

- Backup your DNS settings somewhere

- Import to CloudFlare

- Change name servers in your domain registrar cabinet

- 90 mins and ... profit

Now I cannot see my direct DO server IP when I resolve my DNS:

So, I just found out that Firefox rendering engine was rewritten, now it boasts the fastest speeds and support for ... socks5 proxies, both on mobile and desktop.



Also projects like orbot+orfox help in more extreme cases.

snakers4 (Alexander), April 13, 2018

So, usually I try to stay away from such controversial topics, but I have to address and elephant in the room. You all know, that originally I am from Russia and I have quite liberal world views.

Seeing that many people start to ride the hype and advertising some expensive "solutions", this is why today I decided to do a post about creating your own SOCK5 proxy server via a droplet on Digital Ocean:

- Post - - note that unlike my other posts - this one is a step-by-step explanation;

- It explains how to create your own SOCK5 proxy-server using Ubuntu and Digital Ocean with dante;

- The cheapest digital ocean droplet is US$5 per month (you can find such droplets for as low as US$2-3 with inferior service);

- If you use my referral link - you will get US$10 for free -

- Also you can create credentials for your friends and family;

Also note, that foreseeing this s**t - I created aliases for our telegram channel

- In twitter

- In the web


UX is not so great, but it works more or less. Please tell me what you think. I know that the majority of readers are Russians and we have quite a negative mentality, but this is one of the cases when you have to share this message and my post as much as possible. We will be doing an adapted post on as well.

And I know that there are free proxy lists. But if you create a simple service today - tomorrow you can add layers to it (see some hints in the article) and not rely on other people.

If you like what I shared - please support our channel (see a pinned message)

TF speech competition ended.


In my opinion it was a very interesting domain, but on day one it was apparent that there is a public repo with 87% accuracy. So I guess 90% is a decent improvement, but judging by team sizes - it is just stacking. Also in such competitions there is no chance in winning money. Also also - this was just blatant TF marketing.

New competitions


-- This year it sucks - small prizes, small data, will be just stacking 100 Unets =( Last year I was too unexperienced to participate =(

- - Intel Movidius competition. It also sucks - because you have to use only limited types of hardware and software. Basically this is a marketing campaign

snakers4 (Alexander), December 22, 2017

Оффтоп, но как бы про такое лучше рассказать максимально большому числу людей. Пошлите всем своим друзьям, чтобы не было мучительно обидно.

Не секрет, что "сытые" годы привели к тому, что вероятность встретить на улице "гоп-стоп", бандитов, алкашей и отморозков упала. Но не будучи лохом, и продавая товары на Авито по мелочи очень давно (все остальные сайты полное говно, несмотря на абсолютную мерзопакостность алгоритмов Авито и их бизнес-модели, но это отдельная история) - я начал видеть активных жуликов только примерно год назад, как раз аккурат после начала валютного кризиса. Капитан очевидность также подсказывает, что это неспроста.

Вот 3 бизнес-модели жуликов, с которыми я столкнулся (они по-своему гениальны):

1. Если товар "дорогой" (я продавал картонную кровать из Икеи), то вам пишет СМС реальный человек (или робот с телефона, который также читает человек), упоминая цену и ваше имя в СМС. Потом он звонит (из другого региона кстати) и предлагает перевести предоплату на вашу карту. (Еще кстати звонки на его телефон как-то странно тарифицируются...) Вроде пока ок. Он спрашивает банк и говорит, что ему надо подумать. В реальности он пробивает по своей базе какая дырка в безопасности есть в таком банке. Потом он перезванивает и просит номер карты и говорит, что мол готов сейчас скинуть деньги и приехать вечером. Как бы номер карты это не криминал, но потом он просит код из СМС. Антракт. При очевидных попытках потроллить - вы сразу попадаете в бан на звонки. Дозвониться можно через скайп - и троллинг милицией вызывает бурю веселого мата в ответ - как минимум развлечение. На следующий день - телефон уже недоступен и через скайп.

2. Вам приходит такая СМС с указанием, что вам перевели деньги. Логично - 2017 год на дворе и все говно-сервисы по идее должны сделать escrow - но никто нормальный в России естественно этим пользоваться не будет. Пройдя по ссылке - вы видите это - Сломанный CSS и какая-то пародия на домен и админку. Топорно. Обратите внимание, что имя и цена заказа были спарсены в базу жуликов.

3. Приходит СМС - С именем и суммой. Потом пройдя по ссылке вы видите такой сайт - Причем андроид сразу подсказывает вам в чем фишка. Домен уже лучше подделали - не сразу отличить от субдомена.

А теперь самое классное:

1 Если вы пойдете в милицию - то с высокой степенью вероятности вам откажут в помощи за отсутствием состава преступления, если вы не повелись. Это как потерять биткоины - не преступление;

2 Парсинг, база, говно-домены и динамический сайт с простейшим АПИ, тупые психологические трюки - все до боли гениально и просто;

3 Если у вас "продвинутый" банк - авторизация по СМС, регистрация по номеру телефона с СМС на старый номер и прочее - то вас ждет приятный сюрприз. Плюс иногда даже по номеру карты + CVV на иностранных сайтах можно что-то купить. А учитывая такие эпизоды - - 3 цифры подбираются брутфорсом по идее;
