mlpack_preprocess_describe(1)

πŸ’– mlpack_preprocess_describe β€” bestie edition πŸ’–

okay so bestie, we're diving into mlpack_preprocess_describe(1), the User Commands manual page for the mlpack utility that does descriptive statistics. it's giving ✨ data girlie ✨ and i'm obsessed. let's get into it πŸ’…


✨ NAME ✨

mlpack_preprocess_describe β€” descriptive statistics, no cap πŸŽ€


πŸ“œ SYNOPSIS πŸ“œ

mlpack_preprocess_describe -i unknown [-d int] [-P bool] [-p int] [-r bool] [-V bool] [-w int] [-h -v]

🌸 DESCRIPTION 🌸

so this lil utility takes a dataset and prints out the descriptive statistics of the data. and what even is descriptive statistics, you ask? it's literally the discipline of quantitatively describing the main features of a collection of information, or the quantitative description itself. periodt πŸ’…

the program does not modify the original file, bestie β€” it just prints the statistics out to the console instead. the printed result will look like a table. cute, right?

optionally, the width and precision of the output can be adjusted by you, the user, using the --width (-w) and --precision (-p) parameters. a user can also select a specific dimension to analyze if there are too many dimensions. the --population (-P) parameter can be specified when the dataset should be considered as a population. otherwise, the dataset will be considered as a sample. okay slay ✨

so, a simple example where we want to print out statistical facts about the dataset X.csv using the default settings? we could run:

$ mlpack_preprocess_describe --input_file X.csv --verbose

and if we want to customize the width to 10 and precision to 5 and consider the dataset as a population, we could run:

$ mlpack_preprocess_describe --input_file X.csv --width 10 --precision 5 --verbose

🫢 REQUIRED INPUT OPTIONS 🫢

  • --input_file (-i) [unknown] β€” Matrix containing data, (yes bestie, you literally have to give it data, it's not optional πŸ™ˆ)

πŸ‘‘ OPTIONAL INPUT OPTIONS πŸ‘‘

  • --dimension (-d) [int] β€” Dimension of the data. use this to specify a dimension. default value 0.
  • --help (-h) [bool] β€” default help info.
  • --info [string] β€” print help on a specific option. default value ''.
  • --population (-P) [bool] β€” if specified, the program will calculate statistics assuming the dataset is the population. by default, the program will assume the dataset as a sample.
  • --precision (-p) [int] β€” precision of the output statistics. default value 4.
  • --row_major (-r) [bool] β€” if specified, the program will calculate statistics across rows, not across columns. (remember that in mlpack, a column represents a point, so this option is generally not necessary. iykyk 🌈)
  • --verbose (-v) [bool] β€” display informational messages and the full list of parameters and timers at the end of execution.
  • --version (-V) [bool] β€” display the version of mlpack.
  • --width (-w) [int] β€” width of the output table. default value 8.
