mbiases - compute a new set of value for the matrices A[][] and PI[].  

SYNOPSIS

mbiases
{-i <input compiled matrices file>}
{-f <biases list file>}
{-o <output compiled matrices file>}
 

DESCRIPTION

mbiases takes a list of biases for tag transitions and compute a new set of value for the matrices A[][] and PI[].

OPTIONS

mbiases supports the following options:
-i Input Matrices file
The matrices file created by the mtrain program (compiled form) (default: MM).
-f Biases list file
This file indicates the preferences for transitions biases to be used to reajust the values in the A[][] and PI[] matrices. See the format below (default: biases.lst).
-o Output compiled file
The output matrices file (default: MM.new).
-v version.

FORMAT

 
Biases file 
AJ0  NN1  +4 
NN2  +4 
VVB  -4 
VVZ  -4 
AT0  NN1  =.5 
NN2  =.2 
VVB  =.3 
!OTHER  =0 
!PI  PRP +4 
NN1  +1 
!OTHER  -2 
..... 
The formalism indicates that the transition probability between the first state and the second state will be decreased (increased), if the rate (third column) is negative (positive). The flag !PI appearing in the first column indicates that the values concern the matrix PI, i.e. the initial state.
The Rate indicated in the third column can range from the value [-10..+10]. This takes into account the standard deviation of the state and computes a linear function to increase or decrease the different values.

!PI  WP  +2
