# Dataset Card for YOLOv8-TO_Data

<!-- Provide a quick summary of the dataset. -->

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

## Dataset Description
<!-- Provide the basic links for the dataset. -->


- **Created by:** Thomas Rochefort-Beaudoin
- **License:** MIT
- **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

<!-- This section provides a description of the dataset fields, and additional information about the dataset structure such as criteria used to create the splits, relationships between data points, etc. -->

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.


## Citation

<!-- If there is a paper or blog post introducing the dataset, the APA and Bibtex information for that should go in this section. -->
