![]() ![]() What we have done is this: In the Process window, Split-validation operator splits the incoming data stream (from training.csv) in 70:30 ratio. Complete all port connections as shown in Figure V. From the repository (Figure I), drag imported tovalidate.csv data source and also (from Operators window) drag Apply Model operator into the center Process window. Shift back to Process window (by clicking on Process just above the left panel). Drag Apply Model ( Modeling->Model Application->Apply Model) and Performance (Evaluation->Performance) operators to right panel. Search for Logistic Regression operator and drag it into the left-panel. Drag Logistic regression operator, Apply Model operator and Performance operator to the two parts of window as shown. Import into RapidMiner repository, data file training.csv as shown in the figures below.įigure-VI: Split-validation window. At the same time, we use this model to classify for us hitherto unclassified data (data in tovalidate.csv file). (Operators: Split-validation Performance Apply model)ĭ. 70% of records go into building model, and 30% records are used to gauge model’s performance. Training data will be split in 70:30 ratio. Given training data (training.csv), we will build a logistic regression model. Import files training.csv and tovalidate.csvī. Using the bash script as mentioned in Part-I, the file bank-full.csv was ripped into two files around 4000 randomly selected records were stored in tovalidate.csv file and training.csv file was left with the remaining around 41000 records.Ī. In what follows, some little familiarity with RapidMiner operators will be desirable. bat extension as appropriate for your OS double-click it to start RapidMiner. ![]() Inside scripts folder, look for file: RapidMinerGUI. Declare JAVA_HOME, download and unzip the package and it is ready for work. Being Java based, RapidMiner can be run in either Windows or in Linux. The free versions limitation is that complete data should be in memory for analysis. The Starter and (open-source) community versions of RapidMiner (rapidminer 5.3.015) are free. ![]() RapidMiner Studio 6 can be downloaded from here. In this blog, we proceed first with setting up RapidMiner Studio for conducting the experiment and then discuss results. Select Analytics, then create the shadow dataset of beers from the bucket of beer-sample.In Part-I of the blog, we have described the data set for logistic modelling. Once this is complete, we will need to setup Analytics. You can then navigate back to your Buckets and see beer-sample.

Once downloaded and unpackaged you will want to setup the license: Command Line Activation Next you will need to download and install the CData JDBC driver for Couchbase. Provision a single-node cluster (NOTE: use the default values for cluster configuration).If you do not have an existing Couchbase Server EE cluster, the following links will get you up and running quickly: I am using a single node local install of Couchbase Server EE but the information in this article applies to any Couchbase Server EE cluster. You will first need a Couchbase Server Enterprise Edition (EE) 6.x cluster with the Data and Analytic services enabled. More details regarding this driver can be found here. This article will guide you through the steps needed to setup the connection from RapidMiner to Couchbase Analytics using the CData JDBC driver for Couchbase.
