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:
