Hi John!
The time for the first batch of 50 units was 500 hours. The total time for the first 16 batches of 50 units was 5,731 hours. What’s the learning rate?
-The answer is 92%.
-How to get the answer? ( In your lectures, you do have mentioned of calculating learning rate but have not explained how)Thanks.
The average time per batch for 16 batches is 5,731/16 = 358.1875 hours.
Using the doubling rule, if the learning rate is R, then the time for the first batch is 500. The average time per batch for 2 batches is 500 x R.
The averages time per batch for 4 batches is 500 x R^2
The average time per batch for 8 batches is 500 x R^3
The average time per batch for 16 batches is 500 x R^4So 500 x R^4 = 358.1875
R^4 = 358.1875 / 500 =0.716375
R = fourth root of 0.716375 = 0.92 or 92%
