Functions in this Module(6)

log_to_activity_projection

Convert an EventLog into an EventLogActivityProjection
All traces with the same activity sequence are aggregated into one trace with a frequency count.
This effectively constructs all trace variants, with their count.
Source
fn log_to_activity_projection(log*: EventLog) → EventLogActivityProjection

Arguments

Returns

import r4pm
log = r4pm.import_item('EventLog','path/to/file')

res = r4pm.bindings.log_to_activity_projection(log)
Defined inprocess_mining/src/core/event_data/case_centric/utils/activity_projection.rs:95

get_num_cases

Get the total number of cases in the projection
Source
fn get_num_cases(projection*: EventLogActivityProjection) → u64

Arguments

Returns

import r4pm
projection = r4pm.import_item('EventLogActivityProjection','path/to/file')

res = r4pm.bindings.get_num_cases(projection)
Defined inprocess_mining/src/core/event_data/case_centric/utils/activity_projection.rs:199

get_top_n_variants

Get the n most frequent process variants, sorted by frequency (descending)
Each variant includes the activity sequence as names, its count, and percentage of total cases.
To get all variants, pass n = get_num_variants or use the get_variants function.
To get only the most frequent variant, pass n = 1.
Assumes projection.traces is sorted by descending frequency, as maintained by the provided
constructors.
Source
fn get_top_n_variants(projection*: EventLogActivityProjection, n*: i64<uint>) → Vec<ProcessVariant>

Arguments

Returns

import r4pm
projection = r4pm.import_item('EventLogActivityProjection','path/to/file')

res = r4pm.bindings.get_top_n_variants(projection, 1)
Defined inprocess_mining/src/core/event_data/case_centric/utils/activity_projection.rs:246

get_num_variants

Get the number of distinct trace variants in the projection
Source
fn get_num_variants(projection*: EventLogActivityProjection) → i64<uint>

Arguments

Returns

Defined inprocess_mining/src/core/event_data/case_centric/utils/activity_projection.rs:193

get_projection_activities

Source
fn get_projection_activities(projection*: EventLogActivityProjection) → Vec<String>

Arguments

Returns

import r4pm
projection = r4pm.import_item('EventLogActivityProjection','path/to/file')

res = r4pm.bindings.get_projection_activities(projection)
