General Detection-based Text Line Recognition Open
We introduce a general detection-based approach to text line recognition, be it printed (OCR) or handwritten (HTR), with Latin, Chinese, or ciphered characters. Detection-based approaches have until now been largely discarded for HTR becau…

On Transfer in Classification: How Well do Subsets of Classes Generalize? Open
In classification, it is usual to observe that models trained on a given set of classes can generalize to previously unseen ones, suggesting the ability to learn beyond the initial task. This ability is often leveraged in the context of tr…

Preserving Fine-Grain Feature Information in Classification via Entropic Regularization Open
Labeling a classification dataset implies to define classes and associated coarse labels, that may approximate a smoother and more complicated ground truth. For example, natural images may contain multiple objects, only one of which is lab…

Preventing Manifold Intrusion with Locality: Local Mixup Open
Mixup is a data-dependent regularization technique that consists in linearly interpolating input samples and associated outputs. It has been shown to improve accuracy when used to train on standard machine learning datasets. However, autho…

Inferring Graph Signal Translations as Invariant Transformations for Classification Tasks Open
The field of Graph Signal Processing (GSP) has proposed tools to generalize harmonic analysis to complex domains represented through graphs. Among these tools are translations, which are required to define many others. Most works propose t…
