let the multi-indexer know about any big caches we’ve made multi-indexer. Also lets nnindexer know about other prebuilt indexers so it can attempt to just add points to them as to avoid a rebuild.

wbia.algo.hots.nn_weights.mark_name_valid_normalizers(qnid, neighb_topnid, neighb_normnid)

Helper func that allows matches only to the first result for a name

Each query feature finds its K matches and Kn normalizing matches. These are the candidates from which it can choose a set of matches and a single normalizer.

A normalizer is marked as invalid if it belongs to a name that was also in its feature’s candidate matching set.

Parameters

• neighb_topnid (ndarray) – marks the names a feature matches

• neighb_normnid (ndarray) – marks the names of the feature normalizers

• qnid (int) – query name id

Returns

neighb_selnorm - index of the selected normalizer for each query feature

CommandLine:

wbia.algo.hots.old_chip_match module

class wbia.algo.hots.old_chip_match.AlignedListDictProxy(key2_idx, key_list, val_list)

Bases: utool.util_dev.DictLike_old

simulates a dict when using parallel lists the point of this class is that when there are many instances of this class, then key2_idx can be shared between them. Ideally this class wont be used and will disappear when the parallel lists are being used properly.

DEPCIRATE AlignedListDictProxy’s defaultdict behavior is weird

wbia.algo.hots.pipeline module

Hotspotter pipeline module

Module Notation and Concepts:

PREFIXES: qaid2_XXX - prefix mapping query chip index to qfx2_XXX - prefix mapping query chip feature index to

• nns - a (qfx2_idx, qfx2_dist) tuple

• idx - the index into the nnindexers descriptors

• qfx - query feature index wrt the query chip

• dfx - query feature index wrt the database chip

• dist - the distance to a corresponding feature

• fm - a list of feature match pairs / correspondences (qfx, dfx)

• fsv - a score vector of a corresponding feature

• valid - a valid bit for a corresponding feature

PIPELINE_VARS: nns_list - maping from query chip index to nns

• qfx2_idx - ranked list of query feature indexes to database feature indexes

• qfx2_dist - ranked list of query feature indexes to database feature indexes

• qaid2_norm_weight - mapping from qaid to (qfx2_normweight, qfx2_selnorm)

  = qaid2_nnfiltagg[qaid]

CommandLine:

To see the ouput of a complete pipeline run use

# Set to whichever database you like python main.py –db PZ_MTEST –setdb python main.py –db NAUT_test –setdb python main.py –db testdb1 –setdb

# Then run whichever configuration you like python main.py –query 1 –yes –noqcache -t default:codename=vsmany python main.py –query 1 –yes –noqcache -t default:codename=vsmany_nsum

Todo

• Don’t preload the nn-indexer in case the nearest neighbors have already

been computed?

Description of Plot

You’ll notice that there are 4 plots. This is necessary to visualize a grid with nans. Each plot shows points in the 2-dimensional grid with corners at (0, 0) and (40, 40). The top left plot has these coordinates labeled. The other 3 plots correspond to the top left grid, but in these plots at least one of the dimensions has been “nanned”. In the top right the x-dimension is “nanned”. In the bottom left the y-dimension is “nanned”, and in the bottom right both dimensions are “nanned”. Even though all plots are drawn as a 2d-surface only the topleft plot is truly a surface with 2 degrees of freedom. The top right and bottom left plots are really lines with 1 degree of freedom, and the bottom right plot is actually just a single point with 0 degrees of freedom.

In this example I create 10 Gaussian blobs where the first 9 have their means laid out in a 3x3 grid and the last one has its mean in the center, but I gave it a high standard deviation. I’ll refer to the high std cluster as 9, and label the other clusters at the grid means (to agree with the demo code) like this:

` 6   7   8 3   4   5 0   1   2 `

Looking at the top left plot you can see clusters 0, 1, 2, 4, 6, and 8. The reason the other cluster do not appear in this grid is because I’ve set at least one of their dimensions to be nan. Specifically, cluster 3 had its y dimension set to nan; cluster 5 and 7 had their x dimension set to nan; and cluster 9 had both x and y dimensions set to nan.

For clusters 3, 5, and 7, I plot “nanned” points as lines along the nanned dimension to show that only the non-nan dimensions can be used to distinguish these points. I also plot the original position before I “nanned” it for visualization purposes, but the learning algorithm never sees this. For cluster 9, I only plot the original positions because all of this data collapses to a single point [nan, nan].

Red points are of class 0, and blue points are of class 1. Points in each plot represent the training data. The colored background of each plot represents the classification surface.
