Dataset of exact and Monte Carlo sampled square-lattice self-avoiding polygons

This dataset contains exact and Monte Carlo sampled square-lattice self-avoiding polygons (SAPs) for reproducible computational studies. It includes 536 exact free canonical classes at even perimeters P=4–16 and 12,152 Monte Carlo samples at P=64,128,256,512,1024, and 2048. Each...

Green finance moderates the association between foreign direct investment and green economic growth in Southeast Asian economies

This study investigates how green finance (GF) moderates the relationship between foreign direct investment (FDI) and green economic growth (GEG) in seven Southeast Asian economies over 2013–2023. Using pooled OLS, fixed effects, random effects, and feasible generalized least squ...

Attention-enhanced vision transformer hashing for hybrid image retrieval

Large-scale image retrieval requires compact representations without substantially sacrificing retrieval accuracy. However, Vision Transformer Hashing (VTS) concatenates all output tokens before hash projection, resulting in a high-dimensional hashing head with considerable model...

Preregistered analysis plan and dataset-selection screening for "Directional Hull Summaries for Budgeted SVM Training: Coverage Limits and Reconstruction-Guided Repair"

This record registers the analysis plan for an expanded experimental study, together with the code and screening output that fixed the dataset suite. It was deposited before any subset selector was executed on that suite, and it contains no experimental results. The first round o...
