             Here is a PEEB classifier pre-trained on Bird-11K and finetuned on CUB-200 (see our [NAACL 2024 paper](https://arxiv.org/abs/2403.05297) and [code](https://github.com/anguyen8/peeb/tree/inspect_ddp)).\n The demo shows how one runs PEEB on an existing image and edit descriptors to modify the classifier (without any re-training).

             Steps:
             1. **Select an image**. Then, PEEB will show its grounded explanations and the top-1 predicted label with associated softmax confidence score.
             2. **Hover mouse over text descriptors** to see the corresponding region used to match to each text descriptor.
             3. **Edit the text under [Custom Descriptions]()** which correspond to one extra, new class (i.e. 200+1 = 201). Further editing will overwrite this class' descriptors.
             4. **Click on Predict** to see the grounded explanations and the top-1 label for the newly modified CUB-201 classifier.
