• Abstract: In e-commerce system, category prediction is to automatically predict categories of given texts. Different from traditional classification where there are no relations between classes, category prediction is reckoned as a standard hierarchical classification problem since categories are usually organized as a hierarchical tree. In this paper, we address hierarchical category prediction. We propose a Deep Hierarchical Classification framework, which incorporates the multi-scale hierarchical information in neural networks and introduces a representation sharing strategy according to the category tree. We also define a novel combined loss function to punish hierarchical prediction losses. The evaluation shows that the proposed approach outperforms existing approaches in accuracy.

  We propose a novel, efficient and self-supervised method capable of discovering previously unknown categories at test time.

Experimental evaluations, bolstered by state-of-the-art benchmark comparisons, testify to the efficacy of our solution.

  Conventional detectors suffer from performance degradation when dealing with long-tailed data due to a classification bias towards the majority head categories.

BACL consistently achieves performance improvements across various datasets with different backbones and architectures.

  Weakly-supervised action localization aims to localize and classify action instances in the given videos temporally with only video-level categorical labels. We propose a hierarchical mining strategy under video-level and snippet-level manners, i.e., hierarchical supervision and hierarchical consistency mining. We show that HiM-Net outperforms existing methods on THUMOS14 and ActivityNet1.3 datasets with large margins by hierarchically mining the supervision and consistency.

  This paper presents a general prediction model to hierarchical multi-label classification (HMC), where the attributes to be inferred can be specified as a strict poset. It is based on a top-down classification approach that addresses hierarchical multi-label classification with supervised learning by building a local classifier per class. The proposed model is showcased with a case study on the prediction of gene functions for Oryza sativa Japonica, a variety of rice.

• On Clustering Categories of Categorical Predictors in Generalized Linear Models [0.0]
  We propose a method to reduce the complexity of Generalized Linear Models in the presence of categorical predictors. The traditional one-hot encoding, where each category is represented by a dummy variable, can be wasteful, difficult to interpret, and prone to overfitting. This paper addresses these challenges by finding a reduced representation of the categorical predictors by clustering their categories.

• Inducing a hierarchy for multi-class classification problems [11.58041597483471]
  In applications where categorical labels follow a natural hierarchy, classification methods that exploit the label structure often outperform those that do not. In this paper, we investigate a class of methods that induce a hierarchy that can similarly improve classification performance over flat classifiers. We demonstrate the effectiveness of the class of methods both for discovering a latent hierarchy and for improving accuracy in principled simulation settings and three real data applications.

  Weakly supervised temporal action localization is a newly emerging yet widely studied topic in recent years.

The post-classification pipeline aggregates the snippet-level features first and then predicts the video-level classification score based on the aggregated feature.
