Update a Sentiment Analysis Model

New Altair Community Member

Updated Nov 5, 2024 by Jocelyn

Hi,

I built a sentiment analysis model by using 1000 sampling data.

Now, I have additional 1000 examples, and I would like to update the model.

I know that I can input those 2000 example records and train the model again.

However, it is not efficient to do so.

Is there any method to update the trained model by new sampling?

Thanks!

Just one caveat with it, it will only work if the model generate can be updatable. The Deep Learning algo is not updatable whereas Naive Bayes is.

Exactly, it's a nice option in theory, but unfortunately most popular algorithms don't work with it: decision trees (and their variants), linear and logistic regression, neural nets, SVMs, k-NN, etc., are all not updatable. In fact, Naive Bayes is about the only common one I can think of that is!
