Parameters of the learning process

The parameters of the learning process are displayed in the right part of the main screen. These are:

database - name of the database in use

dates - date on which the currently opened database was created, and the present date (dates are displayed in the UK or US format depending on the setting in Miscellaneous : Options : Date-format)

day - number of days that have passed since creating the database in use

memorized - number of items that have already been memorized

intact - number of items that have not yet been memorized

total - total number of items in the database (total = memorized + intact)

outstanding - (1) number of items that are scheduled for repetition on the current day, and (2) the number of items that have scored grades below 4 in the current session (the latter items will take part in the final drill)

burden +/- - change of the burden parameter in the current session (see below)

burden - average number of repetitions per day

mean time - average repetition time in seconds

workload - average time spent on repetitions per day (workload = burden * mean-time)

interval +/- - change of the interval parameter in the current session (see below)

interval - average current interval between repetitions for items in the database

factor - average E-factor for items in the database

repetition - (1) average number of repetitions, and (2) the average number of memory lapses for items in the database

lapses +/- - change of the lapses parameter in the current session (see below)

lapses (FI) - proportion of items that are not remembered at repetitions (the value FI stands for the requested forgetting index)

retention - estimated proportion of memorized items which the learner is likely to recall

grade - average grade provided at repetitions

time - total learning time in the current session

(see also Item parameters and Repetition parameters)

Item parameters

Item parameters are displayed in the bottom-left quarter of all editing windows (Edit, Learn, Search, etc.).

These are:

number - number of the item

repetition - number of repetitions and the number of memory lapses

interval - current interval

dates - date of the last repetition and the date of the next repetition (the difference between the two is interval)

E-factor - E-factor of the item (the greater the E-factor, the easier the item)

future reps - estimated number of repetitions of the given item in the next 30 years (computed from the matrix of O-factors)

U-factor - U-factor of the item (current interval divided by the previous interval)

(see also Repetition parameters and Learning parameters)

Repetition parameters

Repetition parameters are displayed in the bottom-right quarter of all editing windows (Edit, Learn, Search, etc.).

These are:

grade - grade provided in the most recent repetition

opt interval - optimal interval which should precede the next repetition (computed from the OF matrix: old_interval * O-factor)

new interval - interval which will precede the next repetition (this value is obtained by randomly modifying opt interval)

next rep - date of the next repetition (current date + new interval)

new e-factor - new E-factor for the recently repeated item (grades above 4 increase E-factors; grades below 4 decrease E-factors)

cases - number of repetition cases that have been used to compute the values of the relevant R-factor and O-factor

R-factor - value of the relevant R-factor (1) before and (2) after the recently made repetition

O-factor - value of the relevant O-factor (1) before and (2) after the recently made repetition
