EXAMPLES for `evaluate.py`:
EXAMPLE 1: Run euclidean distance with top n
`evaluate.py -e -n 10`
or simply
`evaluate.py -n 10`
EXAMPLE 2: Run euclidean distance for the first 10 values of top n and graph them
`evaluate.py -M 10`
EXAMPLE 3: Run comparison between baseline and rerank for the first 5 values of top n and graph them
`evaluate.py -M 5 -C`
EXAMPLE 4: Run for kmeans, 10 clusters
`evaluate.py -K 10`
EXAMPLE 5: Run for mahalanobis, using PCA for top 100 eigenvectors to speed up the calculation
`evaluate.py -m -P 100`
EXAMPLE 6: Run rerank for customized values of RERANKA, RERANKB and RERANKL
`evaluate.py -r -a 11 -b 3 -l 0.3`
EXAMPLE 7: Run on the training set with euclidean distance and normalize feature vectors. Draw confusion matrix at the end.
`evaluate.py -t -1 -c`
EXAMPLE 8: Run euclidean distance standardising the feature data for the first 10 values of top n and graph them.
`evaluate.py -2 -M 10`
EXAMPLE 8: Run for rerank top 10 and save the names of the images that compose the ranklist for the first 5 queries: query.txt, ranklist.txt.
`evaluate.py -r -s 5 -n 10`
EXAMPLE 9: Display mAP. It is advisable to use high n to obtain an accurate results.
`evaluate.py -A -n 5000`
EXAMPLE 10: Run euclidean distance specifying a different data folder location
for data int the same folder as evaluate.py:
`evaluate.py --data ./`
or for data in another folder:
`evaluate.py --data ./foo/bar/`
EXAMPLES for `opt.py`:
EXAMPLE 1: optimize top 1 accuracy for k1, k2, lambda speeding up the process with PCA, top 50 eigenvectors
`opt.py -P 50`
EXAMPLE 2: optimize mAP for k1, k2, lambda speeding up the process with PCA, top 50 eigenvectors
`opt.py -P 50 -A`
