Optimal multimodal fusion for multimedia data analysis

Abstract

Considerable research has been devoted to utilizing multimodal features for better understanding multimedia data. However, two core research issues have not yet been adequately addressed. First, given a set of features extracted from multiple media sources (e.g., extracted from the visual, audio, and caption track of videos), how do we determine the best modalities? Second, once a set of modal-ities has been identified, how do we best fuse them to map to se-mantics? In this paper, we propose a two-step approach. The first step finds statistically independent modalities from raw features. In the second step, we use super-kernel fusion to determine the optimal combination of individual modalities. We carefully ana-lyze the tradeoffs between three design factors that affect fusion performance: modality independence, curse of dimensionality, and fusion-model complexity. Through analytical and empirical studies, we demonstrate that our two-step approach, which achieves a care-ful balance of the three design factors, can improve class-prediction accuracy over traditional techniques.

Recomputing p-values needs the paper’s full text.

Claims the paper makes

This paper’s full text isn’t openly available, so its claims and self-check weren’t run. The registry and citation checks still apply.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
