Detailed Description

Implements fitting of a two-step function to a number sequence.

Constructor & Destructor Documentation

construct with parameters

Parameters:

x_	number sequence that we want to fit
delta_01_	penalty for change from a to b
delta_10_	penalty for change from b to a
beta_	is the inverse temperature

double LocARNA::FitOnOff::best_once_on	(	double	c0,
		double	c1
	)

best path that is "on" (=c1) exactly once

Parameters:

c0	off-value
c1	on-value

pf_t LocARNA::FitOnOff::forward	(	double	c0,
		double	c1
	)

compute forward partition functions fills tables v

std::pair< double, double > LocARNA::FitOnOff::optimize	(	double	c0,
		double	c1
	)

optimize c0 and c1 by gradient optimization

void LocARNA::FitOnOff::print_table	(	const std::string &	name,
		const std::vector< bool > &	v
	)		const

Print boolean vector to cout

Parameters:

name	Identifier name to be printed
v	Vector

void LocARNA::FitOnOff::print_table	(	const std::string &	name,
		const std::vector< pf_t > &	v
	)		const

Print vector of partition functions (pf_t) to cout

Parameters:

name	Identifier name to be printed
v	Vector

void LocARNA::FitOnOff::print_tables ( ) const

Print DP-tables for debugging to cout

double LocARNA::FitOnOff::viterbi	(	double	c0,
		double	c1,
		bool	traceback
	)

compute the viterbi score (and optionally path) fills tables v, optionally compute t and trace

Parameters:

c0	off-value
c1	on-value
traceback	whether to perform traceback
