Model Card for BioTrove

BIOTROVE is a new suite of vision-language foundation models for biodiversity. These CLIP-style foundation models were trained on BIOTROVE-40M, which is a large-scale dataset of 40 million images of 33K species of plants and animals. The models are evaluated on zero-shot image classification tasks.

Model type: Vision Transformer (ViT-B/16, ViT-L/14)
License: MIT
Fine-tuned from model: OpenAI CLIP, MetaCLIP, BioCLIP

These models were developed for the benefit of the AI community as an open-source product. Thus, we request that any derivative products are also open-source.

Model Description

BioTrove is based on OpenAI's CLIP model. The models were trained on BIOTROVE-40M for the following configurations:

BIOTROVE-O: Trained a ViT-B/16 backbone initialized from the OpenCLIP's checkpoint. The training was conducted for 40 epochs.
BIOTROVE-B: Trained a ViT-B/16 backbone initialized from the BioCLIP's checkpoint. The training was conducted for 8 epochs.
BIOTROVE-M: Trained a ViT-L/14 backbone initialized from the MetaCLIP's checkpoint. The training was conducted for 12 epochs.

Model Training

See the Model Training section on the Github for examples of how to use BioTrove models in zero-shot image classification tasks.

We train three models using a modified version of the BioCLIP / OpenCLIP codebase. Each model is trained on BioTrove-40M, on 2 nodes, 8xH100 GPUs, on NYU's Greene high-performance compute cluster. We publicly release all code needed to reproduce our results on the Github page.

We optimize our hyperparameters prior to training with Ray. Our standard training parameters are as follows:

--dataset-type webdataset 
--pretrained openai 
--text_type random 
--dataset-resampled 
--warmup 5000 
--batch-size 4096 
--accum-freq 1 
--epochs 40
--workers 8 
--model ViT-B-16 
--lr 0.0005 
--wd 0.0004 
--precision bf16 
--beta1 0.98 
--beta2 0.99 
--eps 1.0e-6 
--local-loss 
--gather-with-grad 
--ddp-static-graph 
--grad-checkpointing

For more extensive documentation of the training process and the significance of each hyperparameter, we recommend referencing the OpenCLIP and BioCLIP documentation, respectively.

Model Validation

For validating the zero-shot accuracy of our trained models and comparing to other benchmarks, we use the VLHub repository with some slight modifications.

Pre-Run

After cloning the Github repository and navigating to the BioTrove/model_validation directory, we recommend installing all the project requirements into a conda container; pip install -r requirements.txt. Also, before executing a command in VLHub, please add BioTrove/model_validation/src to your PYTHONPATH.

export PYTHONPATH="$PYTHONPATH:$PWD/src";

Base Command

A basic BioTrove model evaluation command can be launched as follows. This example would evaluate a CLIP-ResNet50 checkpoint whose weights resided at the path designated via the --resume flag on the ImageNet validation set, and would report the results to Weights and Biases.

python src/training/main.py --batch-size=32 --workers=8 --imagenet-val "/imagenet/val/" --model="resnet50" --zeroshot-frequency=1 --image-size=224 --resume "/PATH/TO/WEIGHTS.pth" --report-to wandb

Model's Limitation

All the BioTrove models were evaluated on the challenging CONFOUNDING-SPECIES benchmark. However, all the models performed at or below random chance. This could be an interesting avenue for follow-up work and further expand the models capabilities.

In general, we found that models trained on web-scraped data performed better with common names, whereas models trained on specialist datasets performed better when using scientific names. Additionally, models trained on web-scraped data excel at classifying at the highest taxonomic level (kingdom), while models begin to benefit from specialist datasets like BIOTROVE-40M and Tree-of-Life-10M at the lower taxonomic levels (order and species). From a practical standpoint, BioTrove is highly accurate at the species level, and higher-level taxa can be deterministically derived from lower ones.

Addressing these limitations will further enhance the applicability of models like BioTrove in real-world biodiversity monitoring tasks.
