prepare_examples: Convert a dataset of type 'log' into a preprocessed format.

In processpredictR: Process Prediction

Convert a dataset of type log into a preprocessed format.

Description

an event log is converted into a tibble where each row contains a cumulative sequence of activities per case. This sequence will eventually be feeded to the Transformer model's token embedding layer.

Usage

prepare_examples(
  log,
  task = c("outcome", "next_activity", "next_time", "remaining_time", "remaining_trace",
    "remaining_trace_s2s"),
  features = NULL,
  ...
)

Arguments

log	log: Object of class log or derivatives (grouped_log, eventlog, activitylog, etc.).
task	character: a process monitoring task for which to prepare an event log.
features	character (default NULL): additional features. Appends attributes (if present) numeric_features and/or categorical_features to a preprocessed event log.
...	additional arguments.

Value

a preprocessed dataset of class ppred_examples_df.

Examples
