# MARIDA
**MARIDA** is a dataset for sparsely labeled marine debris which consists of 11 MSI bands. This dataset contains a training set of 694 samples along with a validation set of 328 samples and a test set of 350 samples. All image samples are originally 256 x 256 pixels. Wecombine both the original validation set and test set into one single test set (678 samples). Weemploy the same approach as DFC2020’s where we divide 256 x 256 pixels into 9 smaller patches of 96 x 96 pixels. Thus, our final training set contains 5,622 training samples, 624 validation samples and 6,183 test samples. All images are 96 x 96 pixels.
## How to Use This Dataset
