Experimental study
on BDES
nGoal: evaluate the accuracy of
predictions generated
by BDES method and other three methods under five behavior patterns.
nExperiments:
nGenerate rating sequences based five
behavior patterns
nApply four methods on each rating
sequence to get predictions
nMeasure the accuracy of predictions
for each behavior pattern
nMeasurement: absolute and relative
errors between predictions
and ratings
nThe distribution of errors is
plotted using cumulative frequency figure.
