# Convnextv2_base pretrained on BigEarthNet v2.0 using Sentinel-1 & Sentinel-2 bands
> **_NOTE:_** This version of the model has been trained with a different band order that is not compatible with the newer versions and does not match the order proposed in the technical documentation of Sentinel-2.
>
> The following bands (in the specified order) were used to train the models with version 0.1.1:
> - For models using Sentinel-1 only: Sentinel-1 bands `["VH", "VV"]`
> - For models using Sentinel-2 only: Sentinel-2 10m bands and 20m bands `["B02", "B03", "B04", "B08", "B05", "B06", "B07", "B11", "B12", "B8A"]`
> - For models using Sentinel-1 and Sentinel-2: Sentinel-2 10m bands and 20m bands and Sentinel-1 bands = `["B02", "B03", "B04", "B08", "B05", "B06", "B07", "B11", "B12", "B8A", "VH", "VV"]`
>
> Newer models are compatible with the order in the technical documentation of Sentinel-2 and were trained with the following band order:
> - For models using Sentinel-1 only: Sentinel-1 bands `["VV", "VH"]`
> - For models using Sentinel-2 only: Sentinel-2 10m bands and 20m bands `["B02", "B03", "B04", "B05", "B06", "B07", "B08", "B8A", "B11", "B12"]`

This model was trained on the BigEarthNet v2.0 (also known as reBEN) dataset using
the Sentinel-1 & Sentinel-2 bands.
It was trained using the following parameters:
- Number of epochs: up to 100 (with early stopping after 5 epochs of no improvement based on validation average
precision macro)
- Batch size: 512
- Learning rate: 0.001
- Dropout rate: 0.15
- Drop Path rate: 0.15
- Learning rate scheduler: LinearWarmupCosineAnnealing for 1000 warmup steps
- Optimizer: AdamW
- Seed: 42
The weights published in this model card were obtained after 15 training epochs.
