Suggesting an N-Hot Encoding approach, in the preprocessing phase of categorical data
A python gist for balancing (re-sampling) a training dataset to match a reported positive-negative class ratio, in the unseen dataset When we know the unseen’s pos-neg class ratio (or “guess” it from the LB..) we should give a try at balancing the training dataset, to reflect it. I wrote a python gist for it, using […]

A JSFiddle playground for 1.2.2 module – 2D SVG examples https://jsfiddle.net/morkrispil/y2vythsc/ Notes: The black border styling of the circle and rect had to be “tweaked” in order to work inside a “0 0 1 1” viewbox size IMHO there were some x coordinate errors in the PATH example, in order to get the “I […]
The official python docker container does exactly what it should. It automatically copies the requirements.txt file and your current directory into /usr/src/app. It should then automatically pip install the dependencies from the requirements.txt, before running the actual Dockerfile commands But sometimes python libraries require additional system setups by themselves (one might consider it a pip bug..). For example, working with ssdeep, a […]

Excellent. Note how the author correctly sets the true meaning of http header name and codes, poorly chosen ages ago (“Authorization” header, 401 code, 403 code)
The observer is probably the GOF pattern with the most impact on networking. It is a massaging pattern by itself. It’s quite simple, though. The subscribers, interested with a certain topic, subscribe with a publisher for updates regarding that topic. The publisher, triggered by our topic-aware system, then publishes the topic updates to the right subscribers. Use case Every […]
