Pseudocode Yes Algorithm 1: Optimization-based encoding.
Open Source Code No The paper does not include an unambiguous statement that the authors are releasing the source code for their own method, nor does it provide a direct link to a code repository.
Open Datasets Yes We select Times New Roman and Helvetica as representatives of serif and sans-serif English fonts, respectively. Besides, to verify the generalizability of our framework in different languages, we also conduct experiments on Song, which is the most commonly used Chinese font. We use the open source font editor Font Forge1 to obtain rendered glyph images and corresponding SVG commands. 1https://fontforge.org/
Dataset Splits No The paper does not specify exact split percentages or absolute sample counts for training, validation, or test sets, nor does it reference predefined splits with citations for dataset partitioning.
Hardware Specification No The paper does not provide specific details about the hardware used to run its experiments, such as GPU or CPU models, or memory specifications.
Software Dependencies No The paper mentions using 'Adam' as an optimizer and 'Font Forge' as an open-source font editor, but it does not provide specific version numbers for these or any other key software dependencies or libraries.
Experiment Setup Yes For the weight factors in the first stage, we set λvq = 5, λpercep = 0.01, λm = λA = 1. In the second stage, we set λimg = 1 and λmsg = 10−5. The number of iterations k is set to 200.
