Model Details

Model Description

UCSCPhytoViT83 is a Vision Transformer (ViT) model fine-tuned for image classification of phytoplankton species using labeled images collected from the Imaging FlowCytobot (IFCB) at UCSC. The model is fine-tuned from the pre-trained google/vit-base-patch16-224-in21k base model. The model was trained on images that are aggregated from IFCB104, IFCB161, and IFCB116

Uses

Direct Use

This model can be used directly for classifying phytoplankton images captured by Imaging FlowCytobots instruments. Focus has been on capturing the variability of the phytoplankton community in Monterey Bay, CA, USA. It is intended for researchers.

Images should be transformed before inference:

    transforms.Compose([
    transforms.Resize((224, 224)),  # match ViT input size
    transforms.Normalize(mean=(0.485, 0.456, 0.406),
                         std=(0.229, 0.224, 0.225))
])

Out-of-Scope Use

This model is not intended for classifying non-phytoplankton images or images from different microscopy systems without proper retraining or adaptation. For the IFCB, the model was trained for instruments that are triggering on PMT-B, so particles and cells with no or limited chlorophyll may not be well represented here.

Bias, Risks, and Limitations

The model was trained on IFCB images collected at UCSC/MBARI and mostly in Monterey Bay, CA, USA or San Francisco Bay, CA, USA and may not generalize well to images from other instruments or regions. Users should validate model predictions with domain experts when possible.

How to Get Started with the Model

Install the transformers library and load the model as shown in the example above. For best results, use images preprocessed similarly to the IFCB dataset (see above).

Training Details

Training Data

The model was trained on approximately 558,000 labeled IFCB images representing 83 classes.

Training Procedure

• Preprocessing: Images were resized and normalized consistent with ViT base requirements.

Evaluation

Testing Data, Factors & Metrics

• The model was evaluated on a held-out test set of IFCB images.
• Metrics include accuracy, precision, recall, and F1-score across phytoplankton classes.
