Running Interactive Learning with Carnegie Learning
Algebra I Tutor
See also Learning by
Demonstration in batch-mode
SimStudent can be tutored by Carnegie Learning
Algebra I Tutor (the CL Tutor, hereafter). All what you need is to pose
training problems for SimStudent. The training problems must be stored
as BRD (even though the steps in the BRD won't be used for learning).
You can also use the CL Tutor to test SimStudent
(i.e., to assess the quality of the production rules generated by
SimStudent). To do so, you can just give SimStudent a set of test
problems. The test problems must be stored as the BRD files with
_complete_ solutions, since SimStudent will be tested for each of the
stpes in a BRD whether or not SimStudent can perform the step correctly
(i.e., SimStudent won't make a solution for a given problem, but rather
perform single steps and will be judged their correctness).
Instruction to run Interactive Learning in batch-mode
1. Save BRD files for training
BRD files both for training and testing must be
saved as individual BRD files each contain a single problem with a
single solutions (and optional incorrect steps, which might be
especially handy when you want to test if SimStudent learns the same
error as human students do)
2. Run a CL Tutor server
InquirySolverTutor and run the server
3. Run SimStudent
3.1. Make a shell script
You just need to invoke the class for a student
interface that you authored. Specify following command line
run SimStudent in a batch-mode
run Interactive Learning
||Use a cache
(hence it speeds up) for flagged feedback if <flag> is true.
use InquirySolverTutor as an oracle to get flagged feedback
use InquirySolverTutor as an oracle to get hints
machine on which the InquirySolverTutor is running
See also a list of
command line arguments.
Sample shell script is available
3.2 Run SimStudent
Once you run SimStudent, you have a few things that you may want
to pay attention:
||A text file contains the production rules that have
been learned most recently. If you are interested in how
production rules had been learned, then take a look at
the pr-age folder, which is described below.
||A folder (directory) where the past
productionRules.pr files are archived. There are two
types of archive files shown below:
contains a total of yyy production rules that
are learned in zzz demonstrated steps.
which shows the production rules learned after the
xxx-th training problem is completed with the
total of yyy production rules learned in zzz steps.
