Dataset Details

Dataset Description

An imbalanced version of the Stanford Dogs dataset designed for testing class imbalance mitigation techniques, including but not limited to synthetic data generation.

This version of the dataset was constructed by randomly splitting the original dataset into train, val, and test sets with a 60/20/20 split. For 15 randomly chosen classes, we then removed all but 10 of the training examples.

# Split the dataset into train, val, and test sets
import fiftyone.utils.random as four
train, val, test = four.random_split(dataset, split_fracs=(0.6, 0.2, 0.2))
splits_dict = { "train": train, "val": val, "test": test }

# Get the classes to limit
import random
classes = list(dataset.distinct("ground_truth.label"))
classes_to_limit = random.sample(classes, 15)

# Limit the number of samples for the selected classes
for class_name in classes_to_limit:
    class_samples = dataset.match(F("ground_truth.label") == class_name)
    samples_to_keep = class_samples.take(10)
    samples_to_remove = class_samples.exclude(samples_to_keep)
    dataset.delete_samples(samples_to_remove)
