💖 mlpack_radical(1) 💖

okay so bestie, let me put you on to mlpack_radical — it's a User Command from the mlpack family, and it's literally the moment for independent component analysis. main character energy fr.

✨ SYNOPSIS ✨

mlpack_radical -i unknown [-a int] [-n double] [-O bool] [-r int] [-s int] [-S int] [-V bool] [-o unknown] [-u unknown] [-h -v]

---

🦋 DESCRIPTION 🦋

So this is an implementation of RADICAL, which is a method for independent component analysis (ICA). no cap. Here's the whole vibe: say we have an input matrix X — the goal is to find a square unmixing matrix W such that Y = W * X, and the dimensions of Y are independent components. that's the dream, that's the assignment.

Lowkey important heads-up: if the algorithm is running particularly slowly, try reducing the number of replicates. that's the move. 🐢➡️🐇

The input matrix you're doing ICA on gets specified with the --input_file (-i) parameter. The output matrix Y can be saved with the --output_ic_file (-o) output parameter, and the output unmixing matrix W can be saved with the --output_unmixing_file (-u) output parameter. slay, everything has a home.

For example, to perform ICA on the matrix X.csv with 40 replicates, saving the independent components to ic.csv, the following command may be used:

$ mlpack_radical --input_file X.csv --replicates 40 --output_ic_file ic.csv

periodt. that's the whole thing. 💅

👑 REQUIRED INPUT OPTIONS 👑

These ones are not optional bestie, you literally need them.

• --input_file (-i) [unknown] — Input dataset for ICA. that's the one. the whole meal depends on it.

---

🌸 OPTIONAL INPUT OPTIONS 🌸

the fun customization zone, we love her:

• --angles (-a) [int] — Number of angles to consider in brute-force search during Radical2D. Default value is 150. she's thorough.
• --help (-h) [bool] — Default help info. your classic rescue button. 🫶
• --info [string] — Print help on a specific option. Default value is ''.
• --noise_std_dev (-n) [double] — Standard deviation of Gaussian noise. Default value is 0.175. a lil noise, as a treat.
• --objective (-O) [bool] — If set, an estimate of the final objective function is printed. receipts, basically. 🧾
• --replicates (-r) [int] — Number of Gaussian-perturbed replicates to use (per point) in Radical2D. Default value is 30.
• --seed (-s) [int] — Random seed. If 0, 'std::time(NULL)' is used. Default value is 0. so if you want reproducibility that's your girly, otherwise she just vibes with the clock.
• --sweeps (-S) [int] — Number of sweeps; each sweep calls Radical2D once for each pair of dimensions. Default value is 0.
• --verbose (-v) [bool] — Display informational messages and the full list of parameters and timers at the end of execution. the yapper mode, i respect it. 🗣️
• --version (-V) [bool] — Display the version of mlpack.

---

🎀 OPTIONAL OUTPUT OPTIONS 🎀

where your results go to shine:

• --output_ic_file (-o) [unknown] — Matrix to save independent components to.
• --output_unmixing_file (-u) [unknown] — Matrix to save unmixing matrix to.

💀 reminder: if it's crawling, reduce the replicates. don't just sit there suffering, okay?

that's the page, bestie. go unmix some components, you absolute icon. 💜✨
