Reproducibility Variable Result LLM Response
Research Type Experimental Experiments on both synthetic and real data validate our theory and demonstrate the superiority of SHPOS over the state-of-the-art. We evaluate our method on a list of tasks, including both synthetic and real datasets. The empirical results demonstrate the superiority of our method over the state-of-the-art.

Pseudocode Yes Algorithm 1 Stochastic Hamiltonian Particle Optimization Sampling
Open Source Code No The paper does not provide a statement about releasing code or a link to a code repository for the described methodology.
Open Datasets Yes Four publicly available benchmark datasets from LIBSVM1, a3a, w8a, a8a, and ijcnn1 are used for evaluation. ... 1https://www.csie.ntu.edu.tw/~cjlin/libsvmtools/datasets/ ... 6 datasets from UCI2 and LIBSVM. ... 2http://archive.ics.uci.edu/ml/datasets.php
Dataset Splits No The paper mentions using datasets for evaluation but does not specify training, validation, or test dataset splits (e.g., percentages, sample counts, or references to predefined splits).
Hardware Specification No The paper does not provide any specific details about the hardware (e.g., CPU, GPU models, memory) used to run the experiments.
Software Dependencies No The paper does not list specific software dependencies with version numbers.
Experiment Setup Yes We use 1000 particles that initialized by drawing from a Gaussian distribution with mean [ 4, 2]T and variance 0.252. ... We report negative log-likelihood versus the number of data passes with 50 particles on datasets a3a and w8a ... we use a Gamma(1, 0.1) prior for the inverse covariance and adopt a one-hidden-layer neural network with 50 hidden units.
