Explanation-based Training with Differentiable Insertion/Deletion Metric-aware Regularizers

1 code implementation19 Oct 2023 Yuya Yoshikawa, Tomoharu Iwata

To improve the faithfulness, we propose insertion/deletion metric-aware explanation-based optimization (ID-ExpO), which optimizes differentiable predictors to improve both the insertion and deletion scores of the explanations while maintaining their predictive accuracy.

Action Class Relation Detection and Classification Across Multiple Video Datasets

no code implementations15 Aug 2023 Yuya Yoshikawa, Yutaro Shigeto, Masashi Shimbo, Akikazu Takeuchi

The Meta Video Dataset (MetaVD) provides annotated relations between action classes in major datasets for human action recognition in videos.

Training Deep Models to be Explained with Fewer Examples

no code implementations7 Dec 2021 Tomoharu Iwata, Yuya Yoshikawa

For improving the interpretability, reducing the number of examples in the explanation model is important.

Gaussian Process Regression with Local Explanation

no code implementations3 Jul 2020 Yuya Yoshikawa, Tomoharu Iwata

In the proposed model, both the prediction and explanation for each sample are performed using an easy-to-interpret locally linear model.

Neural Generators of Sparse Local Linear Models for Achieving both Accuracy and Interpretability

no code implementations13 Mar 2020 Yuya Yoshikawa, Tomoharu Iwata

Additionally, the prediction is interpretable because it is obtained by the inner product between the simplified representations and the sparse weights, where only a small number of weights are selected by our gate module in the NGSLL.

A Nonparametric Delayed Feedback Model for Conversion Rate Prediction

no code implementations1 Feb 2018 Yuya Yoshikawa, Yusaku Imai

In this paper, we propose a nonparametric delayed feedback model for CVR prediction that represents the distribution of the time delay without assuming a parametric distribution, such as an exponential or Weibull distribution.

Learning from Noisy Label Distributions

no code implementations11 Aug 2017 Yuya Yoshikawa

In this problem, each instance with a feature vector belongs to at least one group.

STAIR Captions: Constructing a Large-Scale Japanese Image Caption Dataset

1 code implementation ACL 2017 Yuya Yoshikawa, Yutaro Shigeto, Akikazu Takeuchi

In recent years, automatic generation of image descriptions (captions), that is, image captioning, has attracted a great deal of attention.

Cross-Domain Matching for Bag-of-Words Data via Kernel Embeddings of Latent Distributions

no code implementations NeurIPS 2015 Yuya Yoshikawa, Tomoharu Iwata, Hiroshi Sawada, Takeshi Yamada

We propose a kernel-based method for finding matching between instances across different domains, such as multilingual documents and images with annotations.

Latent Support Measure Machines for Bag-of-Words Data Classification

no code implementations NeurIPS 2014 Yuya Yoshikawa, Tomoharu Iwata, Hiroshi Sawada

With the latent SMM, a latent vector is associated with each vocabulary term, and each document is represented as a distribution of the latent vectors for words appearing in the document.
