+# Adapter `lenglaender/xlm-roberta-base-lora-cls-yelp-polarity` for google-t5/t5-base
+
+An [adapter](https://adapterhub.ml) for the `google-t5/t5-base` model that was trained on the [yelp_polarity](https://huggingface.co/datasets/yelp_polarity/) dataset and includes a prediction head for classification.
+
+This adapter was created for usage with the **[Adapters](https://github.com/Adapter-Hub/adapters)** library.
+
+## Usage
+
+First, install `adapters`:
+
+```
+pip install -U adapters
+```
+
+Now, the adapter can be loaded and activated like this:
+
+```python
+from adapters import AutoAdapterModel
+
+model = AutoAdapterModel.from_pretrained("google-t5/t5-base")
+adapter_name = model.load_adapter("lenglaender/xlm-roberta-base-lora-cls-yelp-polarity", source="hf", set_active=True)
+```
+
+## Architecture & Training
+
+LoRA has r=8 and alpha=8 and was trained with dropout=0.1
+
+## Evaluation results
+
+Accuracy on Amazon polarity dataset: 98.15%
