Switch

--log

Description

A log transformation of the group norm frequency information.

Details

Normalizes the group norm frequency information using the following formula: ln(x+1).

Other Switches

Required Switches:

-d, -g, -t

The transformation switches are used during feature extraction and therefore need at least one feature extraction command:

--add_ngrams, --add_lex_table, etc.

Example Commands

./dlatkInterface.py -d dla_tutorial -t msgs -c user_id --add_ngrams -n 1 --log

# produces the table feat$cat_met_a30_2000_cp_w$msgs$user_id$16to3$1gra
./dlatkInterface.py -d dla_tutorial -t msgs -c user_id --add_lex_table -l met_a30_2000_cp --weighted_lex --log
