Bi-directional Ontology Versioning BOV
his paper defines a new type of ontology versioning: Bi-directional Ontology Versioning: BOV. BOV provides bi-directional mappings and transformations between concepts in two ontology versions. BOV is identified by two levels mapping processes: linguistic mapping and structural mapping. BOV can satisfy the requirement of mapping in distributed environment
Generalized Max Pooling
State-of-the-art patch-based image representations involve a pooling
operation that aggregates statistics computed from local descriptors. Standard
pooling operations include sum- and max-pooling. Sum-pooling lacks
discriminability because the resulting representation is strongly influenced by
frequent yet often uninformative descriptors, but only weakly influenced by
rare yet potentially highly-informative ones. Max-pooling equalizes the
influence of frequent and rare descriptors but is only applicable to
representations that rely on count statistics, such as the bag-of-visual-words
(BOV) and its soft- and sparse-coding extensions. We propose a novel pooling
mechanism that achieves the same effect as max-pooling but is applicable beyond
the BOV and especially to the state-of-the-art Fisher Vector -- hence the name
Generalized Max Pooling (GMP). It involves equalizing the similarity between
each patch and the pooled representation, which is shown to be equivalent to
re-weighting the per-patch statistics. We show on five public image
classification benchmarks that the proposed GMP can lead to significant
performance gains with respect to heuristic alternatives.Comment: (to appear) CVPR 2014 - IEEE Conference on Computer Vision & Pattern
