Reproducibility Variable Result LLM Response
Research Type Experimental We demonstrate the effectiveness of our algorithm on synthetic experiments and an ion channel recording data, with runtimes significantly outperforming batch MCMC.
Researcher Affiliation Academia 1University of Washington, Seattle, WA, USA.
Pseudocode Yes Algorithm 1 SG-MCMC [...] Algorithm 2 SG-MCMC for HMM
Open Source Code No The paper does not provide any statement or link indicating that the source code for the described methodology is publicly available.
Open Datasets Yes We evaluate the performance of our proposed SG-RLD algorithm for HMMs on both synthetic and real data. [...] Finally, we apply SG-RLD to a large ion channel recording data set and compare to batch MCMC. In particular, we consider a 1MHz recording from Rosenstein et al. (2013) of a single alamethicin channel. This data was previously investigated in Palla et al. (2014) and Tripuraneni et al. (2015)...
Dataset Splits No The paper mentions the use of synthetic and real datasets, and refers to "held out probability" and "test data" but does not specify explicit training, validation, or test splits by percentages or sample counts. For example, it does not state "70% for training, 15% for validation, 15% for testing" or similar.
Hardware Specification No The paper does not provide any specific details about the hardware (e.g., CPU, GPU models, memory, cloud instance types) used to run the experiments.
Software Dependencies No The paper does not provide specific version numbers for any software libraries, frameworks, or programming languages used in the experiments.
Experiment Setup Yes Algorithm 2 SG-MCMC for HMM: initialize A(0) and φ(0) k for n = 0, 1, 2 , Niter do Periodically estimate the buffer length B and the minimum subchain gap ν according to Sec. 3. Sample subchains S of length L from p(e S). [...] Further details on these datasets and how we set L and |e S| are in the Supplement. [...] Details of the parameter settings used to generate the data are in the Supplement.
