There are many machine learning libraries that have good implementations of LDA (e.g. Gensim), so it should be "relatively" straightforward to create the topics and clustering based on the abstracts of the papers.
- jamessb 12y agoI think there might be confusion about wht nl was referring to. Yes, the link is to a list (produced by Karpathy) of papers on which LDA has been performed. But one of the listed papers is also by Kapathy ("Deep Fragment Embeddings for Bidirectional Image Sentence Mapping"), and I think this might be what nl is complimenting as being done quickly.
- nl 12y agoYes this is the case. Thanks
