This sample demonstrates how a model is generated out of a dataset using the Support Vector Machine (SVM) algorithm using tuned hyper parameter values. You can find these parameter values in the <ML_HOME>/samples/tuned/svm/hyper-parameters file. The sample uses a data set to generate a model, which is divided into two sets for training and testing.


Follow the steps below to set up the prerequisites before you start.

  1. Download WSO2 Machine Learner, and start the server. For information on setting up and running WSO2 ML, see Getting Started.
  2. Download and install jq (CLI JSON processor). For instructions, see jq Documentation.
  3. If you are using Mac OS X, download and install GNU stream editor (sed). For instructions, see GNU sed Documentation.

Executing the sample

Follow the steps below to execute the sample.

  1. Navigate to <ML_HOME>/samples/tuned/svm/ directory using the CLI.

  2. Execute the following command to execute the sample: ./

Output of the sample

Once the sample is successfully executed, you can view the summary and the prediction of the model  as described below.

By  default , the sample generates the model in the <ML_HOME>/models/ directory of your machine. For example, the generated file is in the following format denoting the date and time when it was generated: wso2-ml-svm-tuned-sample-analysis.Model.2015-09-03_17-13-00

Viewing the model summary

You can view the summary of the built model using the ML UI as follows.

  1. Log in to the ML UI from your Web browser using admin/admin credentials and the following URL:  https://<ML_HOST>:<ML_PORT>/ml

  2. Click the Projects button as shown below.
    click Projects button

  3. Click MODELS button of the new analysis which you created by executing the sample as shown below.

  4. Click  VIEW  of the built new model as shown below.
      select model
    You view the summary of the built model as shown below.

Viewing the model prediction

The sample executes the generated model on the   <ML_HOME>/samples/tuned/svm/prediction-test data set, and it prints the value ["0" ] as the prediction result In the CLI logs.
