Pseudocode Yes Algorithm 1: Estimating confusion matrices
Open Source Code No The paper does not provide an explicit statement or link to open-source code for the described methodology.
Open Datasets Yes The datasets used (Bird, RTE, TREC, Dog, Web) are listed in Table 1 and cited (e.g., [22] for Bird, [21] for RTE, [16] for TREC, [9] for Dog, [26] for Web), indicating they are established, publicly accessible datasets.
Dataset Splits No The paper does not explicitly state training, validation, and test splits with percentages or sample counts. It refers to 'real datasets' on which evaluation is performed.
Hardware Specification No The paper does not provide specific details about the hardware used to run the experiments (e.g., GPU models, CPU types, memory).
Software Dependencies No The paper does not list specific software dependencies with version numbers (e.g., Python, PyTorch, TensorFlow versions).
Experiment Setup Yes The default choice of the thresholding parameter is = 10 6. For components that are smaller than , they are reset to .
