Training dataset using SVM

Hi everyone,

i have a training set that i want to train it using SVM, i have already extracted the features using HOG, but i don't know how to proceed with the training, what should i do next and what function to use (i found out that there's more than 1 function :fitcecoc / fitcsvm / ... )

Also, i would like to know , if i changed HOG to LBP, can i use the same steps and same function ?

Thank you in advance.

Hi,

From the dataset, while extracting the features you must be knowing that if this is a binary class problem or a multi-class problem. If it’s a binary class problem, you can use fitcsvm otherwise, you can use fitecoc which fits a multiclass model for SVM classifiers. You can use any features to fit a SVM model whether HOG or LBP but the performance for both the feature sets will be different. You may find this example useful to get started.
