Dataset Card for YOLOv8-TO_Data

This dataset contains the training and testing sets for the YOLOv8-TO paper.

Dataset Description

Datasets
- MMC Dataset Description: The MMC (Minimum Compliance) dataset is derived using the MMC method as the basis for the training dataset, where the segmentation labels are generated from black-and-white density projections obtained via a Heaviside projection. Split: 80% training, 10% validation, 10% testing Usage: Model training and evaluation
- Random Assembly Dataset Description: This dataset consists of assemblies composed of randomly distributed components, generated to allow for cost-effective training data production. The design variables sampled randomly define the segmentation labels for detection and regression tasks. Usage: Training only
- SIMP Dataset Description: Generated using the Solid Isotropic Material with Penalization (SIMP) method, this dataset includes 2000 TO structures, allowing to test the model's capability as a general post-processing tool. Samples: 2000 Usage: Testing
- Low Volume Fraction SIMP Dataset (SIMP5%) Description: Comprising 2000 random SIMP samples with a low volume fraction (5%), this dataset features thin structures that simulate "truss-like" properties suitable for comparison against skeletonization approaches. Samples: 2000 Usage: Testing
- Out-of-Distribution (OOD) Dataset Description: This dataset includes 4 TO structure images from the literature, featuring complex structures like 2D femur structures and cantilever beams optimized under various constraints to test the model's generalization capabilities. Samples: 4 Usage: Testing

Dataset Structure

IMPORTANT: The dataset currently has the design variables of each component in position 1 to 7 in each row. These design variables are currently ignored by the YOLOv8-TO library and are artifacts of when we were trying to do regression directly on the design variables.
