The equation does not correlate to this:

Y = axb

Where Y = cumulative average time per unit to produce x units

a = the time taken for the first unit of output

x = the cumulative number of units produced

b = the index of learning (log LR/log2)

LR = the learning rate as a decimaland the question asked to find LR

May 1, 2021 at 8:11 am #619351The formula is not Y = axe, it is = ax^b

When asked to find the learning rate you cannot be expected to use the formula (because with regard to b it would involves using antilogs and they are not in the syllabus).

Finding the learning rate will only ever involve using the doubling rule and I explain this, with examples, in my free lectures on learning curves.
