MrSEQL

MrSEQL

class MrSEQL(seql_mode='fs', symrep='sax', custom_config=None)[source]

MrSEQL = Multiple Representations Sequence Learning classification model.

Direct Interface to MrSEQLClassifier from mrseql. Note: mrseql itself is copyleft (GPL3). This interface is permissive license (BSD3).

MrSEQL is an efficient time series classifier utilizing symbolic representations of time series, using SAX and SFA features.

Parameters:
seql_modestr, either ‘clf’ or ‘fs’ (default).

In the ‘clf’ mode, Mr-SEQL is an ensemble of SEQL models, while in the ‘fs’ mode Mr-SEQL, trains a logistic regression model with features extracted by SEQL from symbolic representations of time series.

symrepstr, or list or tuple of string, strings being ‘sax’ or ‘sfa’.

default = “sax”, i.e., only SAX features, no SFA features. The symbolic representations to be used to transform the input time series.

custom_configdict, optional, default=None

Customized parameters for the symbolic transformation. If defined, symrep will be ignored. (no documentation of this parameter is provided in the original mrseql code)

Attributes:
is_fitted

Whether fit has been called.
