Rounds all activation_ columns to the specified number of decimal places.
Optionally retains only the neurons named in neurons_keep, dropping all others.
This is useful for reducing file size before archiving or sharing results.
The original data frame is not modified.
Arguments
- results
A data frame or data.table with
activation_columns.- activation_digits
Integer. Number of decimal places to round activation values to.
- neurons_keep
Character vector of neuron names to retain. Names may include or omit the
activation_prefix (e.g."ins_buzz"and"activation_ins_buzz"are equivalent). All other activation columns are dropped. IfNULL(default), all neurons are kept.
See also
trim_directory to apply this to an entire folder of files.
Examples
path <- system.file(
'extdata/five_flowers/soybean/9/230809_0000_buzzdetect.csv',
package = 'buzzr'
)
results <- read_results(path)
