Multimodal Model Evaluation

Compare how each platform handles model evaluation and dataset management tasks.

Pixeltable

import pixeltable as pxt


eval_table = pxt.create_table('model_evaluation', {
    'image': pxt.ImageType(),
    'caption': pxt.String,
    'audio': pxt.AudioType(),
    'ground_truth': pxt.String
})


eval_table['vision_prediction'] = vision_model(eval_table.image)
eval_table['text_prediction'] = text_model(eval_table.caption)
eval_table['audio_prediction'] = audio_model(eval_table.audio)


eval_table['vision_accuracy'] = (
    eval_table.vision_prediction == eval_table.ground_truth
)
eval_table['multimodal_score'] = combine_predictions(
    eval_table.vision_prediction,
    eval_table.text_prediction,
    eval_table.audio_prediction
)


results = eval_table.aggregate({
    'avg_accuracy': eval_table.vision_accuracy.mean(),
    'multimodal_performance': eval_table.multimodal_score.mean()
})

Voxel51 (FiftyOne)

import fiftyone as fo
