A modified svm_predict of LIBSVM for microcontroller.

A modified svm_predict of LIBSVM for microcontroller.

This project will translate trained svm model file into c struct declaration.

Only support for classification.

Prerequisites

• A SVM model trained by svm_train of LIBSVM
• [Optional] A SVM scale range file of LIBSVM

Building

• Compile the model translation program

gcc modelFile2cStruct -o modelFile2cStruct

Translate trained svm model

./modelFile2cStruct model_file > output_file

• The translated svm model struct declaration will store in output_file.
• After that, you are able to add the contain in output_file into your program.
• An example

./modelFile2cStruct ./data/templates.tf.model > model

Example

• The required function for svm prediction is modified and an usage example is in main.c.
• Step
  • Copy translated svm model into your program.
  • Copy the necessary function in main.c into your program.
  • Include the simplified svm.h into your program.
• note: the scale function is optional.
  • If you need scale your feature vector, you need modified following declaration,
  • double lower=xxx,upper=xxx;
  • double feature_max[] = {xxx};
  • double feature_min[] = {xxx};
