Constructor & Destructor Documentation

function fsg_test_anova::fsg_test_anova ( in o )

Member Function Documentation

function fsg::boot ( in o )

inherited

Assigns the subddd property.

function fsg::calculate_grades	(	in	o,
		in	idxs
	)

inherited

May return one grade or a vector thereof

Parameters

idxs	May be either: a cell of feature subsets; or a vector of feature indexes. Developers please note that it is the end class responsibility to give proper treatment to this. The option is left open for speed, as there is no point in using a cell in univariate cases.

function set fsg::data	(	in	o,
		in	data
	)

inherited

Assigns the datasets property.

See also: datasets

Parameters

data	Vector of datasets.

function fsg_test::do_calculate_pairgrades	(	in	o,
		in	idxs
	)

protectedinherited

If sgs is set, performs cross-validation loop based on subddd, otherwise used datasets to test.

function irobj::do_get_html ( in o )

protectedinherited

Abstract. HTML inner body.

function irobj::do_get_report ( in o )

protectedinherited

Default report.

function irobj::extract_log ( in o )

inherited

Parameters

o

Returns: [o, log]

function irobj::get_ancestry	(	in	o,
		in	flag_title
	)

inherited

Parameters

o
flag_title=1

function irobj::get_description	(	in	o,
		in	flag_short
	)

inherited

Returns description string

Precedence according with flag_short:

0: title > short > classtitle
1: short > title > classtitle

Parameters

flag_short=0 I am sealing this to make sure that no class will try to improvise on this function.

function irobj::get_html	(	in	o,
		in	flag_stylesheet
	)

inherited

Parameters

flag_stylesheet=1 Whether to include the stylesheet in the HTML

function irobj::get_methodname	(	in	o,
		in	flag_short
	)

inherited

This is used only to compose sequence string e.g. xxx->yyy->zzz

Parameters

flag_short=0

function irobj::get_params	(	in	o,
		in	data
	)

inherited

Calls Parameters GUI.

If flag_params, tries uip_<class>.m. If fails, tries uip_<ancestor>.m and so on

function irobj::get_report ( in o )

inherited

Object reports are plain text. HTML would be cool but c'mon, we don't need that sophistication.

function fsg::get_yname ( in o )

inherited

Returns: A string for an y-axis label

function fsg::get_yunit ( in o )

inherited

Returns: A string for a y-axis unit

function fsg::reset ( in o )

protectedinherited

function irobj::setbatch	(	in	o,
		in	params
	)

inherited

Sets several properties of an object at once.

Parameters

o
params	Cell followint the pattern {'property1', value1, 'property2', value2, ...}

function fsg_test_anova::test	(	in	o,
		in	dd,
		in	idxs
	)

Member Data Documentation

Property irobj::classtitle

protectedinherited

Class Title. Should have a descriptive name, as short as possible.

Definition at line 50 of file irobj.m.

Property irobj::color

inherited

=[0, .8, 0]. multipurpose feature, routines may use it for different things. Major use is to change the background of objtool and blockmenu. See also classes_html.m

Definition at line 42 of file irobj.m.

Property fsg::data

inherited

See also: datasets

Definition at line 91 of file fsg.m.

Property fsg::datasets

protectedinherited

Assigned by set_data()

If not pairwise (see flag_pairwise), data will be assigned to datasets.

If pairwise, datasets will be a matrix of dimensions (number of pairs)x(numel(data))

Why one would pass a more-than-one-element dataset through data depends on the behaviour of a particular fsg descendant. For instance a two-element vector could be a train-test pair.

Please note that

Definition at line 57 of file fsg.m.

Property fsg::f_aggr

inherited

=. Function pointer to aggregate a vector of pairwise grades. As seen, the default behaviour is taking the least grade obtained among all pairwise gradings.

Definition at line 12 of file fsg.m.

Property fsg::fext

inherited

Some trainable block for convenience. This can be used to pass a pre_std so that it doesn't have to be part of the classifier itself. This block typically is trainable and treats the features independently. Having it as part of the classifier would result in unnecessary repetition of the same operation.

Property fsg::flag_booted

protectedinherited

Definition at line 42 of file fsg.m.

Property fsg_test_anova::flag_logtake

Property fsg::flag_pairwise

protectedinherited

=0;

Definition at line 26 of file fsg.m.

Property irobj::flag_params

protectedinherited

=1. (GUI setting) Whether to call a GUI when the block is selected in blockmenu.m . If true, a routine called "uip_"<class name> will be called.

Definition at line 57 of file irobj.m.

Property fsg::flag_sgs

protectedinherited

Prepared.

Definition at line 37 of file fsg.m.

Property irobj::flag_ui

protectedinherited

(GUI setting) Whether to "publish" in blockmenu and datatool. Note that a class can be "published" without a GUI (set flag_params=0 in this case, at the class constructor).

Property fsg::pvt_flag_pairwise
