  • GitHub repo scikit-learn

    Project mention: Is there a way to map cluster centers back to a dataframe? | | 2021-05-19

    To avoid the issue with convergence (and the discrepancy between the labels_ and cluster_centers_), you can set tol=0, though this can of course lead to issues if convergence is a problem. There was an issue about it here. Assuming it's converged, then the order is fine.

  • GitHub repo gensim

    Topic Modelling for Humans

    Project mention: The Levenshtein Distance in Production | | 2021-06-06

    > Problem statement: the Levenshtein distance is a string metric for measuring the difference between two sequences

    Another variant is "I have a bunch of words (a dictionary) and one query word, and want to find all words from the dictionary that are close to the query word".

    This leads to an interesting class of problems, because you can do clever things where you precompute search structures (Levenshtein automata [0]) from the dictionary. The similarity queries then run (much) faster – in production, performance matters.

    We recently merged a PR like that into Gensim [1].

    This gave a ~1,500x speed-up compared to naively comparing all pairwise strings with Levenshtein distance. A difference between the training step running for years (=unusable) and minutes.



  • GitHub repo recommenders

Relevant data like the home and away team, home runs, RBI’s, and walk’s are all taken into account and passed through layers. There’s no need to reinvent the wheel here, there's a multitude of libraries that enable a coder to implement machine learning theories efficiently. In this case we will be using a library called TFlearn, documentation available from The program will output the home and away teams as well as their respective score predictions.

  • GitHub repo Prefect

    The easiest way to automate your data

    Project mention: Hi, how can I do pipeline automation? | | 2021-04-18

    If you are just starting out or new to doing automation, I would look at just python scripts executed with CRON if on Linux/Mac or Windows Task Scheduler if on Windows. But you'll need bash (Linux/Mac) knowledge or DOS/batch knowledge (Windows). Then graduate to using frameworks. Since you didnt specify what types of jobs you want to automate, for general purpose needs, I would look at a class of frameworks called task orchestration frameworks or workflow management libraries. I would highly recommend dagster as it comes with a native scheduler so you would be free from having to use CRON or Windows Task Scheduler. Other options include prefect, but if you want its other features like its scheduler and web GUI, you'll have to mess with docker. That's what's nice about dagster, it all works out of the box without need for non-Python dependencies.
