Reset can be used to reset selected elements of the learning process in a given database. To use Reset, tick appropriate check-boxes in the Reset dialog box, and choose OK.
The checkbox Database can be used if the entire learning process should be reset in the currently opened database. A reset database can be used by another student, i.e. its parameters are like in a newly created database (e.g. Memorized=0, Burden=0, optimization matrices are reset, etc.).
The checkbox Forgetting index can be used to reset the measurement of the forgetting index. This option may be useful after changing the requested forgetting index (using Miscellaneous : Options : Lapses).
The checkbox Forgetting index counter can be used to reset the counter of repetitions used in measuring the forgetting index. This option will usually be used in association with Forgetting index check-box in the Reset dialog box.
The checkbox Optimal factor matrix can be used to reset the matrix of optimal factors to the shape from before the learning process. This option may be useful in cases of irregular learning, where the matrix of optimal factors assumes a highly irregular shape.
The checkbox Retention factor matrix (and Cases) can be used to reset the matrix of retention factors and well as the matrix of repetition cases. This is equivalent to discarding the information pertaining to the properties of the learners memory and his or her perception of the material in the reset database. This option should be used only then when a substantial change has occurred in the learning process such like: (1) removing a large number of difficult items, (2) adding a large number of easy items, (3) improving the structure of existing items, (4) long break in learning, (5) substantial improvement in the regularity of repetitions (in a neglected database), etc.
The most typical applications of the option Reset are:
* Reset : Database - to pass ones own database to a colleague or to return again to a long unused database
* Reset : Forgetting index and Reset : Forgetting index counter - to resume the measurement of the forgetting index after changing the requested forgetting index (in Miscellaneous : Options : Lapses), or after a substantial change in the difficulty of the database, or after an increase in the regularity of repetitions (that might positively affect the forgetting index)
* Reset : Optimal factor matrix - to restart the process of computing the matrix of optimal factors when it becomes increasingly irregular (e.g. as a result of irregular repetitions)
* Reset : Retention factor matrix - to restart the process of computing all optimization matrices (RF matrix and OF matrix).
In general, the following is the typical order of using the suboptions of Reset with the increasing severity of change to the learning process (irregular repetitions, restructuring databases, changing Lapses, etc.): (1) reset the forgetting index, (2) reset the forgetting index counter, (3) reset the matrix of optimal factors, (4) reset the matrix of retention factors and, only in very drastic cases, (5) rest the database.
