Correct Predictions vs. Eigenfaces Plot
Questions:
1. The trend in the plot is fairly obvious: An increase in the
number of eigenfaces results (roughly) in a corresponding increase in
the number of correct recognitions. This is intuitive because with
each added eigenvector, we increase the amount of potential detail
achievable via projection onto them. The trade-off is
computational weight vs. accuracy, so to get the best accuracy with the
lightest weight computation, we should use about 23 eigenfaces.
2. A couple of recognition errors are as follows,
recognition could have been better for the first mistake, and was pretty
close for the second. Both errors were made using 33 eigenfaces:
