Abstract

There has been an increased interest in multimodal language processing including multimodal dialog, question answering, sentiment analysis, and speech recognition.However, naturally occurring multimodal data is often imperfect as a result of imperfect modalities, missing entries or noise corruption.To address these concerns, we present a regularization method based on tensor rank minimization.Our method is based on the observation that high-dimensional multimodal time series data often exhibit correlations across time and modalities which leads to low-rank tensor representations.However, the presence of noise or incomplete values breaks these correlations and results in tensor representations of higher rank.We design a model to learn such tensor representations and effectively regularize their rank.Experiments on multimodal language data show that our model achieves good results across various levels of imperfection.

  • Multimodal imperfections capture correlations in imperfections across modalities, such as missing modalities or a chunk of time missing in multimodal time-series data.

    “Multimodal imperfections capture correlations in imperfections across modalities (e.g., missing modalities [123], or a chunk of time missing in multimodal time-series data [101]).”

    From MultiBench: Multiscale Benchmarks for Multimodal Representation Learning (2021) · cites this paper as [101]

    Section 4.2 (Rank Analysis; page unavailable) describes structured missingness in multimodal time-series data: all features at a selected time step are dropped. It does not describe a contiguous chunk of time missing, and time steps are selected independently for each modality, not as correlated imperfections across modalities. Section 3.3 says imperfections break correlations in the clean data rather than capture correlations among the imperfections. (LLM, conf=0.86)

  • Current benchmarks typically focus on performance without quantifying the potential drawbacks involved with increased time and space complexity and the risk of decreased robustness from imperfect modalities.

    “Furthermore, current benchmarks typically focus on performance without quantifying the potential drawbacks involved with increased time and space complexity [148], and the risk of decreased robustness from imperfect modalities [101, 123].”
  • Real-world multimodal data is often imperfect as a result of missing entries, noise corruption, or missing modalities entirely, which calls for robust models that can still make accurate predictions despite only having access to noisy and missing signals.

    “Real-world multimodal data is often imperfect as a result of missing entries, noise corruption, or missing modalities entirely, which calls for robust models that can still make accurate predictions despite only having access to noisy and missing signals [101, 123].”
  • Following Liang et al., MULTIBENCH implements types of noise and missing values in time-series data.

    “Following Liang et al., [101], we implement the following types of noise and missing values in time-series data:”
  • Approaches for improving robustness modify the objective function to account for robustness to noisy or missing modalities.

    “These approaches modify the objective function to account for robustness to noisy [101] or missing [89, 111, 123] modalities.”

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.
