Notice: The reproducibility variables underlying each score are classified using an automated LLM-based pipeline, validated against a manually labeled dataset. LLM-based classification introduces uncertainty and potential bias; scores should be interpreted as estimates. Full accuracy metrics and methodology are described in Coakley et alK. L. Coakley, T. Snelleman, H. Hoos, and O. E. Gundersen, "The embrace of open science: An analysis of a decade of AI research and 56 800 conference papers," Under Review, 2026..

| Reproducibility Variable | Result | LLM Response |
|---|---|---|
| Research Type | Experimental | We evaluate DWFS with three real-world HAR datasets, and the results show that DWFS statistically outperforms the state-of-the-arts regarding a combined measurement of accuracy and energy efficiency. |

| Pseudocode | Yes | Algorithm 1 DWFS Generate H; Algorithm 2 DWFS Learning; Algorithm 3 DWFS Inference |
| Open Source Code | No | The paper does not provide any explicit statements or links indicating that the source code for the described methodology is open-source or publicly available. |
| Open Datasets | Yes | Human Activity Sensing Consortium (HASC) 2011 (Kawaguchi et al. 2011): The data of 6 activities was collected with 100 readings per second by 7 subjects using i Phone/i Pod. Human Activity Recognition on Smartphones Dataset (HARSD) (Anguita et al. 2013): The data of 6 activities was collected with 50 readings per second by 30 subjects using a Samsung Galaxy S II. Daily Sport Activities dataset (DSA) (Barshan and Y uksek 2013): The data of 19 activities was collected with 25 readings per second by 8 subjects using body-worn sensors (we use the data collected by the sensor placed on a subject s torso). |
| Dataset Splits | Yes | We conduct the experiments based on 5-fold cross-validation, where we take 1/5 of D in turn for testing, and the other 4/5 of D for training. |
| Hardware Specification | No | The paper mentions the operating system ('Python 2.7 on 64-bit Ubuntu 14.04 LTS operating system') but does not specify any hardware components like CPU, GPU models, or memory. |
| Software Dependencies | No | The paper mentions 'Python 2.7 on 64-bit Ubuntu 14.04 LTS operating system' but does not list any other software libraries, frameworks, or solvers with specific version numbers. |
| Experiment Setup | Yes | The iteration round L for training is set to 5. We use softmax regression as the classification model of DWFS, that the parameter θ is an m (d +1) matrix including intercepts, and we optimize θ iteratively by Broyden-Fletcher-Goldfarb-Shanno (BFGS) algorithm. We model the parameter ψ as a K (d + m) matrix, that ψk(s) = ψk s, and we optimize ψ iteratively via BFGS as well. We set the parameter β = 1.2 which is used to impose instance weight. |
