Re: General Results

Hello @naxiota, Ok, let's see how to help you. Since you are learning, I prefer you to see and repeat with me: You have one file. Here I used a version of the Holy Bible (please see my disclaimer at the end), so I used the Open File operator to read it, extract the content with the Read Document operator and then pass it as a document to Process Documents. Inside the Process Documents super-operator (the kinds of operators that let you put stuff inside those), I did this: Well... * Tokenizing is boring because it's more an internal representation of words, you won't get meaningful things from that. * Also, it is a good idea to Transform Cases because it brings together words with mixed cases (those are not considered the same under normal comparison algorithms). * Now on to something useful: Let's extract all the Nouns from the content. You may be able to do many other things, but this is a simple exercise: you can extract the POS tags using this https://www.ling.upenn.edu/courses/Fall_2003/ling001/penn_treebank_pos.html Now you can do whatever you want with natural language processing. I added the file but please try figuring things out with the pictures I sent and the explanations first, it helps better. Hope this helps, Rodrigo.

RapidMiner & SAP HANA DB Integration using ODBC

Objective:  If you have SAP HANA data base which stores all the enterprise transactional data and want to apply predictive/machine learning algorithms on the HANA data base tables or views using Rapid Miner. This blog gives you the steps to connect SAP HANA data base from Rapid Miner and retrieve tables/views/procedures data and apply Rapid Miner statistical algorithms or machine learning techniques to get the insights of data.  Back Ground and use case:Rapid Miner is a data science platform for teams that unites data prep, machine learning, text mining and predictive model deployment. It is used for business and commercial applications as well as for research, education, training, rapid prototyping, and application development and supports all steps of the machine learning process including data preparation, results visualization, model validation and optimization. SAP HANA is an in-memory, column-oriented, relational database management system developed and marketed by SAP SE. Its primary function as a database server is to store and retrieve data as requested by the applications.With the SAP HANA 2.0 Data Platform of structured and unstructured data,I wanted to do the proof of concept on Text analysis, Market basket analysis, Customer segmentation and other data science use cases using Rapid Miner Studio. The below step by step procedure helps to  connect HANA DB tables/views/procedures from Rapid miner studio. SAP HANA DB & Rapid Miner Integration steps:  1.     Prerequisites : You must have below before trying your hands on Rapid miner models on HANA data.      HANA CLIENT Tools (Which installs required drivers in the client machine)      Rapid Miner Studio Client (Interface to develop Rapid miner models)       User Account in HANA DB with read access on DB Objects.  Optional: Install HANASTUDIO/WEB IDE to analyze or preview SAP HANA data.  2.     Once you Install HANA Client tools, you will see ngdbc.jar file in the below path              C:\Program Files\SAP\hdbclient              Place this ngdbc.jar file below Rapid miner installation folder path              C:\Program Files\RapidMiner\RapidMiner Studio\lib\jdbc  3.     Open the Rapid Miner studio and create data base driver . Go to manage data base drivers and enter the following parameters as shown in picture            Name of driver: HANA_JDBC             Jar file: C:\Program Files\RapidMiner\RapidMiner Studio\lib\jdbc\ngdbc.jar              Port : 30115              Driver class: com.sap.db.jdbc.Driver   4..     Now go to manage data base connections , create data base connection with below parameters. Select previously created driver in the data base system Give the HANA system host, port ,user id, password.  Do the test connection- you should see success message.   You can use tables or views or write SQL script  to retrieve the data. 5.Now use db connect process to import the data and process the data using rapid miner models. From read data base parameters, you can connect tables or views or you can write custom HANA SQL Query.   Writing custom SQL query : Now use other operators in Rapid miner and feed this data based on your usecase.

Re: Can I publish RapidMiner results with Educational Edition license?

Hello @Casper72 I work on rapidminer for most of my ML related works and published some papers as well. The only thing you need to do is to cite rapidminer in your references and where relevant. You can also go through our discussion about citing rapidminer below. https://community.rapidminer.com/discussion/54779/how-to-cite-rapidminer-studio-for-scholarly-publications Hope this helps Varun

[New Extension] Projects

Hello Everybody! I've just released a new extension called "Projects". This extension adds two new entries to your repository actions: This allows you to create a standard setup for a project. It automatically creates a folder structure, add standard processes with defined documentation and so on. The structure for the Project looks like this: Some of the processes already have a implementation. The 04-Learning one looks like this: I hope that these templates can make your life easier andmake yourself more efficient. I appriciate any feedback on the templates and of course on further enhancements! Best, Martin

Re: Feature Selection

Hello, again! Stop! Stop! Stop! Don't make that answer the right one! (My pride says "delete your answer", but my OCD says "leave it there"). TIL that it is more common if we put feature selection inside the cross validation process because otherwise it would lead to biased results. Thanks to @varunm1 for the several links he has sent me. I actually got confused (too many hours programming stuff, you know) but this article got clarity for me: https://rapidminer.com/blog/learn-right-way-validate-models-part-4-accidental-contamination/. Despite my lapsus (and understanding the question), I can now focus on this: (Quote) Let's see: * On each cross validation fold, the selected features will differ. * In the RapidMiner documentation for the Cross Validation operator, it says: (Quote) So, the correct answer is: You get the model trained with all the data (not a specific fold), but only if you connect the mod port somewhere else. The model trained will use the best features found for all of these, though. All the best, Rodrigo.
