Learning Paradigms Command Interpreter
Information for New Version of BPS System
In this new version of BPS system, we added a stochastic learning method
by taking a random weight changes with simulated annealing concept. In order
to keep the feature of previous version (for some reasons, mostly is to save
the time), we emulated the original programming style. In addition, by adding
the command interprter to accept commands from console, it allows user more
freely to access the system. For further implementation or mantainability,
data structure definition for random weights and external declarations are
put in learning.h header file. For the extensibility of LPCI, we have
constructed an interface allows user software to migrate to future products
with minimal change. For more details see the technical documentation.
The Learning Paradigms Command Interpreter supports a command language
to control the execution of the specific network. Each command will be
defined, syntaxed, and if needed a comment will be mentioned. These commands
will be entered only on the console. Commands referring to the display or
execution directly will be noticed immediately on the screen wile other
commands may have no visual effect. In addition, command may not be
abbreviated and may only be enter as lower case.
LPCI COMMAND LISTING
++++++++++++++++++++
!
Purpose : Executes a host operating system command.
Synopsis: ! command-string
Remark : The current command string specified is passed to the host operating
system for execution.
ANNEALING
Purpose : Enables simulated annealing
Synopsis: annealing
Remarks : It is necessary to set schedule before executing this command.
BPS
Purpose : Enables backpropagation model without simulated annealing
Synopsis: bps
Remarks : See previous version documentation.
CLS
Purpose : clear the entire screen.
Synposis: cls
Remarks : This command is effectivly the same as 'cls' command in DOS
environment.
EXIT
Purpose : Exit current command level.
Synopsis: exit
Remarks : The current command level is terminated. If the current command
level was receiving input from the operatore, then this command
causes the workstation to terminate the LPCI.
HELP
Purpose : Display this help facility.
Synopsis: help
Remarks : The HELP command invokes the LPCI HELP facility to display
information about LPCI commands or LPCI itself.
MENU
Purpose : Enables the menu-driven processor.
Synposis: menu
Remarks : The function of menu-driven processor only involve some commands
provided by LPCI.
SHOW ANNEALINGW
Purpose : Displays the current random weights in annealing schedule.
Synopsis: show annealingw
Remarks : The annealing weights displayed is recently defined by annealing
schedule.
SET TRACE
Purpose : Sets the recording of trace data on or off.
Synposis: set trace <on|off>
Remarks : The trace data file contains the entire commands indicated by the
user.
SET LOG
Purpose : Enables or disables logging of the simulated annealing performance
to the specified file.
Synopsis: set log [file_name]
Remarks : The neural network weights and thresholds will be written to the
specified file before annealing start. The annealing random weight
changes defined by annealing schedule and the weights after annealing
proceed will also be recorded. If file_name is not specified, "set
log" will close the logging file. The logging file is automatically
closed when LPCI exits.
SET SCHEDULE
Purpose : Sets the annealing schedule
Synopsis: set schedule epochs lower upper[;epochs lower upper]...
Remarks : Example: set schedule 1000 -1 1;2000 -0.5 0.5
Enables annealing when the number of epochs reachs 1000,then applies
random weight changes with lower bound -1and upper bound 1. The
second schedule can be applied afterthe first schedule is done.
