Episode-Constrained Cross-Validation in Video Concept Retrieval
Jan C. van Gemert, Cor J. Veenman, Jan‐Mark Geusebroek · IEEE Transactions on Multimedia · 2009
Whereas video tells a narrative by a composition of shots, current video retrieval methods focus mainly on single shots. In retrieval performance estimation, similar shots in a narrative may result in performance overestimation. We propose an episode-based version of cross-validation leading up to 14% classification improvement over shot-based cross-validation.
