I am interested in using the workflows recently published in this link
I have already installed the Redfield extension for the conformal prediction but it does not contain the regression conformal prediction.
I think that the workflow is using a new version of the library or it is a private edition.
Could you please give me the link to manually download the latest version because the security of my laptop is stopping me from downloading directly from the Knime server.
you will find local update sites for plugins here: KNIME Analytics Platform Installation Guide
Note that this is for version 4.5. For older versions you can change the download links, or browse other versions of our documentation, e.g. docs.knime.com/?category=analytics_platform&version=4.4.
Indeed, I used the latest version 4.5 and I downloaded manually the zip files from the link below.
The Redfield extension contains some of the nodes but not all of them. For exmple, the Venn Abers or the regression nodes are missing
So if you try to open the regression workflow from the link below, Knime will fail to find the source of the missing node
I’m missing these extensions when opening the workflow:
These are the extensions: Vernalis (community trusted), Redfield (partner), Optimization (KNIME).
Since they all come from different update sites, you will need three local sites to cover them.
(Note that community (experimental) and community (trusted) are two different sites. You need the trusted community update site.)
I installed all the required extensions and I see that Knime recognises all the nodes but not the regression conformal prediction node.
Are you able to open this workflow with no problem?
You’re right, I can install the extension but the version used in the workflow is not the version we have available in our update sites. I will reach out to @Redfield.
What you have found is our test cases for the upcoming release that will include conformal regression (not available in the current version). This way you cannot run these workflows. Please ignore these them. Instead I can recommend this workflow: Conformal prediction workshop by Redfield – KNIME Hub
We are planning to release the updated nodes along with Knime 4.6, in the end of June.
Unfortunately I am interested in the regression workflow and the Venn-abers classification.
I will be looking forward to using them in the next release.
Please let me know if there will be any pre-release that I can play with before June.
It would be nice that you leave the nodes accessible for editing for academic use.
I have some students that will use them and I think that looking inside the code would be more pedagogical instead of using a black box.
Thank you for your interest of our nodes. In the meanwhile our code is open you can check it here: GitHub - RedfieldAB/conformal_prediction
The same repo will be updated and will contain the regression-related code soon.
I am wondering whehther it is now possible to use the nodes for Venn#abers and the conformal regressionas the version of 4.6 was released.
If it is the case, I am looking for the zip file to install them manually.
No, right now they are not released. We still need more time to polish the code.
Venn-Abers predictors are not planned to be part of the upcoming update. Perhaps we will release them later this year.
Finally I can announce that Conformal prediction extension is updated and available for Knime 4.6.
It includes the Conformal regression as well. Here I have prepared a demo workflow:
And if you are interested my colleagues and I have published a paper:
That’s great news, @Redfield
I tried to dowload the Redfield workflow using regression but the dataset is missing.
Do you know where I can get it from?
I have updated this workflow, now the path should be correct, so the workflow can read the files from its data folder.
