Pseudocode Yes Algorithm 1: Querying maps for t using HF-STHM algorithm.
Open Source Code No The paper does not provide an explicit statement about releasing its source code or a link to a code repository. A link provided (https://goo.gl/f9c TDr) is for the dataset used in the experiments, not the implementation code.
Open Datasets Yes Our main dataset1, named as dataset 1, consists of laser scans, each with 180 beams covering 1800 angle and 30 m radius, collected from a busy intersection [6]. Figure 3 [6] shows an aerial view of the area and the location of the sensor. In Section 4.4, we used an additional dataset1 (dataset 2) of a larger intersection, as this section verifies an important part of our algorithm. 1https://goo.gl/f9c TDr
Dataset Splits No The paper describes the datasets used (dataset 1, dataset 2) but does not provide specific details on how these datasets were split into training, validation, and test sets (e.g., percentages, sample counts, or citations to predefined splits).
Hardware Specification No The paper mentions 'a simple Python based implementation' but does not specify any particular hardware (e.g., CPU, GPU models, or memory) used for running the experiments.
Software Dependencies No The paper states 'a simple Python based implementation' but does not list specific software dependencies with version numbers (e.g., Python version, library versions like NumPy, SciPy, or specific ML frameworks).
Experiment Setup Yes SHM and HF-STHM used 1000 bases. DGM is an extension to [1] which calculates occupancy probability based on few past time steps. In this experiment we considered 10 past time steps and 1 m grid-cell resolution for DGM.
