Reproducibility Variable Result LLM Response
Research Type Experimental We evaluate the proposed method on handwritten characters, printed artistic characters, and scene characters. The experimental results validate that the proposed method outperforms existing methods on both character zero-shot and radical zero-shot tasks.

Pseudocode No The paper does not contain any structured pseudocode or algorithm blocks labeled as such.
Open Source Code No The paper does not provide any concrete access information, such as a repository link or explicit statement, regarding the release of its source code.
Open Datasets Yes HWDB1.0-1.1 [Liu et al., 2013] contains 2,678,424 offline handwritten Chinese character images. ICDAR2013 [Yin et al., 2013] contains 224,419 offline handwritten Chinese character images. CTW [Yuan et al., 2019] contains Chinese characters collected from street views.
Dataset Splits Yes From HWDB1.0-1.1, we choose samples with labels in the first m classes of 3,755 characters as the training set, where m ranges in {500,1000,1500,2000,2755}. From ICDAR2013, we choose samples with labels in the last 1000 classes as the test set.
Hardware Specification Yes We implement our method with Py Torch and conduct experiments on an NVIDIA RTX 2080Ti GPU with 11GB memory.
Software Dependencies No The paper mentions "Py Torch" but does not provide specific version numbers for it or any other software dependencies.
Experiment Setup Yes The Adadelta optimizer is used with the learning rate set to 1. The batch size is set to 32. Each input image is resized to 32 32 and normalized to [-1,1]. We adopt a weight decay rate of 10 4 in zero-shot settings to avoid overfitting.
