Hello Community,
I have a dataset that containes those features : Year, Retailer country (country name), product type (string), Performence(float), sales (float $)
I have Year from 2004 to 2007 in this dataset
I want to use a machine learning algorithm in Knime so as to predict sales in 2008 for each couple (country,product type)
Any help thanks in advance

Hi @Abdessamad7
I think predicting sales or predicting whatever is absolutly possible with KNIME. Take a look at the KNIME Hub, and search for regression model workflow see the examples and get inspired. Or go to the KNIME learning hub . And also with KNIME comes the EXAMPLES server with lots of workflows dealing with predictive modelling.

Here we have a few examples for regression models with KNIME:
Regression models (numeric Target)
I can think of a few examples that might show you the possible directions
This site has an introduction to model building with KNIME and uses an example that could be similar to your question:
Concerning the predictions you want you will have to think about how to set up the analysis and prediction. Would you make a prediction for every single product and dealer and what role does the time play in your analysis. Sales within a month or a week.
Then the quality of a model will very much de…
@ScottF provided us with simple workflow that shows how you would set up a regression model and do an evaluation using the RMSE ( Root-mean-square deviation) => the lower the better. The KNIME numeric scorer node has you covered there.
You could switch out the type of model used:
We had a discussion about that here:
And also further information about ways to determine the quality of a model (mostly 1/0 but check out the link).
I have to see if I have an example with a regression targe…
Typically you would use the Scorer nodes. Then there are a few entries dealing with numeric targets, you might want to check them.

predict how many future visitors a restaurant will receive (with H2O.ai)
I was thinking about feeding the prediction of the model back to a correlation node (linear in this case) and then use the absolute value of the correlation to determine the strongest correlations towards the predicted Target.
The data is from a Kaggle competition (https://www.kaggle.com/c/bnp-paribas-cardif-claims-management ) with some transformations and only 500 random cases. So the numbers are just there to demonstrate the nodes. The calculation can be quite costly.
