            Display document to topic mapping after LSI using Gensim

            I am new to using LSI with Python and Gensim + Scikit-learn tools. I was able to achieve topic modeling on a corpus using LSI from both the Scikit-learn and Gensim libraries, however, when using the Gensim approach I was not able to display a list of documents to topic mapping.

            In order to get the representation of a document (represented as a bag-of-words) from a trained LsiModel as a vector of topics, you use Python dict-style bracket-accessing (model[bow]).

            For example, to get the topics for the 1st item in your training data, you can use:

            Normalizing Topic Vectors in Top2vec
            Asked 2022-Feb-16 at 16:13

            I am trying to understand how Top2Vec works. I have some questions about the code that I could not find an answer for in the paper. A summary of what the algorithm does is that it:

            • embeds words and vectors in the same semantic space and normalizes them. This usually has more than 300 dimensions.
            • projects them into 5-dimensional space using UMAP and cosine similarity.
            • creates topics as centroids of clusters using HDBSCAN with Euclidean metric on the projected data.

            what troubles me is that they normalize the topic vectors. However, the output from UMAP is not normalized, and normalizing the topic vectors will probably move them out of their clusters. This is inconsistent with what they described in their paper as the topic vectors are the arithmetic mean of all documents vectors that belong to the same topic.

            This leads to two questions:

            How are they going to calculate the nearest words to find the keywords of each topic given that they altered the topic vector by normalization?

            After creating the topics as clusters, they try to deduplicate the very similar topics. To do so, they use cosine similarity. This makes sense with the normalized topic vectors. In the same time, it is an extension of the inconsistency that normalizing topic vectors introduced. Am I missing something here?

            I got the answer to my questions from the source code. I was going to delete the question but I will leave the answer any way.

            It is the part I missed and is wrong in my question. Topic vectors are the arithmetic mean of all documents vectors that belong to the same topic. Topic vectors belong to the same semantic space where words and documents vector live.

            That is why it makes sense to normalize them since all words and documents vectors are normalized, and to use the cosine metric when looking for duplicated topics in the higher original semantic space.

            Answered 2021-Oct-11 at 15:19

            I'm one of the developers of OCTIS.

            Short answer: If I understood your problem, you can fix this issue by modifying the parameter "bert_path" of CTM and make it dataset-specific, e.g. CTM(bert_path="path/to/store/the/files/" + data)

            TL;DR: I think the problem is related to the fact that CTM generates and stores the document representations in some files with a default name. If these files already exist, it uses them without generating new representations, even if the dataset has changed in the meantime. Then CTM will raise that issue because it is using the BOW representation of a dataset, but the contextualized representations of another dataset, resulting in two representations with different dimensions. Changing the name of the files with respect to the name of the dataset will allow the model to retrieve the correct representations.

            If you have other issues, please open a GitHub issue in the repo. I've found out about this issue by chance.

            It's a matter of scale. If you have 1000 types (ie "dictionary words"), you might end up (in the worst case, which is not going to happen) with 1,000,000 bigrams, and 1,000,000,000 trigrams. These numbers are hard to manage, especially as you will have a lot more types in a realistic text.

            The gains in accuracy/performance don't outweigh the computational cost here.

            If I understand correctly, you have a dataframe with all values and you want to keep the top 10 in each row, and have 0s on remaining values.

            Here we transform each row by:

            • getting the 10th highest values
            • reindexing to the original index of the row (thus the columns of the dataframe) and filling with 0s:
