💖 LINCLASSIF — the linclassif manual page, bestie edition 💖

okay so you opened the manual for linclassif, a General Commands Manual situation, and I am so glad you're here. let's get into it 🫶

✨ NAME ✨

linclassif — predict labels by a linear classification rule 🔥

🌸 SYNOPSIS 🌸

linclassif [options] example_file model_file

🦋 DESCRIPTION 🦋

okay so linclassif is a program that predicts labels by a linear classification rule. that's literally the whole vibe. 👑

now, the two files you hand it are doing different jobs and you need to know which is which:

  • example_file — a file full of testing examples, formatted in SVM^light format ✨
  • model_file — the file holding your rule. it can be either a binary (two-class) rule:
f(x)=w'*x+w0

or a multi-class rule:

f(x)=W'*x

and where do those come from? so glad you asked, bestie — they're produced by svmocas(1) and msvmocas(1), respectively. 💅

💅 OPTIONS 💅

a summary of options is included below. no skips, no skimming, we're doing all of them 🌈

  • -h — show summary of options. the classic "help me" move 🙈
  • -v (0|1) — set the verbosity level. default is 1. turn it down if you want peace 🎀
  • -e — print the classification error, computed from the predicted labels and the labels contained in example_file. yes, it's grading itself. iconic ✨
  • -o out_file — save predictions to the file out_file 📝
  • -t (0|1) — output type. two moods only:
    • 0 … predicted labels (this is the default) 💖
    • 1 … discriminant values 💀

🧚 EXAMPLES 🧚

example one: train the multi-class SVM classifier from example file fiply_trn.light, using svmocas(1) with the regularization constant C=10, verbosity switched off, and save the model to svmocas.model:

svmocas -c 10 -b 1 -v 0 riply_trn.light svmocas.model

example two: compute the testing error of the classifier stored in svmocas.model using testing examples from riply_tst.light, and save the predicted labels to riply_tst.pred:

linclassif -e -o riply_tst.pred riply_tst.light svmocas.model
not me noticing the prose says fiply_trn.light while the actual command says riply_trn.light 😭 i'm keeping it exactly as written, no cap — the original said it, so we said it. 💯

🌈 SEE ALSO 🌈

svmocas(1), msvmocas(1).

go read those too, bestie, they're the ones making the models in the first place 🫶
