Transfer Learning with SVD operator
Contributor IHi, Rapidminer community,
For a university project, I'm working on Transfer Learning. So, I build a model that learns from a source dataset (amazon text reviews with a star rating) and uses this knowledge to predict the stars on the target dataset but also combine information from the source and target to optimize the predictions and reduce the dimensionality with the SVD operator.
In the code that I added, there are 3 SVD's, one for the source, one for the target training and one for target testing. I'm not sure how to connect the pre(processing models) connections. In the code example I added a few apply model's. But this gives the error "Wrong number of attributes, operator expects a fixed number of attributes (100), the actual number was 100".
I also tried to add an extra 'group models' and combine the SVD preprocess models but didn't work either.
Who can help me?

HI @me1234,
Your XML process is broken (it can not be imported into RapidMiner).
To share properly a process, please follow the instructions of this link.

Thanks for your response, quite strange because I did it like in the video. Here is the .rmp file in the attachment.
Hi @me1234,
I inserted SVD, Group Models and Apply Model operators inside the Cross Validation operators.
Now it works.
Does this process answer to your need ?

Lionel
Hi Lionel,
Thanks for your response and work.
The model that you created is not transfer learning. I need to combine the datasets full data of the source and from the target only 70%. You inspired my by putting SVD and apply models in the Cross-Validation.
I have created a new model, with SVD/Apply model inside Cross Validation but gives a mean recall of 31.95% and precision 32.68% and this is less good than the normal process.
I think the problem is in the pre-process combining. I guess what I want to do is not possible with Rapidminer?
Hi @me1234,
if you train a model on a data set and want to score another data set you need to ensure, that the data schema is the same. So number of attributes, type and name has to fit.
If you want to try transfer learning outside of deep learning using neural networks you could do it like the following:
1. Make sure all data you want to use has the same schema as described above
2. Apply multiple models one after another (so hierachical learning (which in fact is deep learning but without the neural networks here)).
3. Keep the first x. models the same, while only retraining the last one(s) with your new data from a different domain.
Here's a simple process sketch to help illustrate the concept:
Hope this helps,
Philipp
