    Project mention: What are state-of-the-art methods for abstractive text summarization ? | | 2021-06-03
  • GitHub repo gensim

    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 flair

    A very simple framework for state-of-the-art Natural Language Processing (NLP)

    Project mention: Advice for how to approach classifying apartment posts on facebook? | | 2021-06-04

    For example, my first approach to the pet sentences would be to label all sentences within a respective text corpus containing according information for either yes or no. You would then convert this to a tertiary tag set, something like ["pet allowed", "pet not allowed", "irrelevant"]. You could then try out a model based on SentenceBert, other sentence-level embeddings/language models or 1D CNNs for this. flairNLP ( is a small, little framework which provides comfortable high-level access to different common language models which integrates perfectly with pyTorch.

    Project mention: Lack of activation in transformer feedforward layer? | | 2021-05-20

    I'm curious as to why the second matrix multiplication is not followed by an activation unlike the first one. Is there any particular reason why a non-linearity would be trivial or even avoided in the second operation? For reference, variations of this can be witnessed in a number of different implementations, including BERT-pytorch and attention-is-all-you-need-pytorch.
