Feature request : Adding D-ETM and other dynamic topic model approaches

[espoirMur]

Nice work here...

I haven't yet played with the code.

I was just asking if this tool can work dynamic topic models approaches like this one .

If yes, how can we integrate it?

Hi! Thank you :)

Yes, we can definitely think of a way to integrate D-ETM as well. We have already integrated ETM, so I think it shouldn't be that hard.

The main issue is related to the timestamps. At this stage, our dataset is stored as a .tsv file composed of three columns: the documents, the partition to which the document belongs (i.e. train, test or validation), and the label. We may consider including an additional column that is optional that represents the timestamp.
As for the integration of the model itself, a good strategy should be to follow the integration of ETM, which should be implemented similarly to D-ETM.

If you want to integrate it, I am at your disposal for further questions. Otherwise, it will probably take me a few weeks to do the whole work.

Cheers,

Silvia

Thanks, you @silviatti for your prompt answer. I will try to have a look tomorrow to see how to integrate the model into this. I will definitely come back to you if I have any question

Hello, @espoirMur
Can I please check if you are still keen on integrating the DETM into OCTIS? If so have you made any progress on this front?
Thank you
