Dataset Card for the Dog ? vs. Food ? (a.k.a. Dog Food) Dataset

Dataset Summary

This is a dataset for binary image classification, between 'dog' and 'food' classes.

The 'dog' class contains images of dogs that look like fried chicken and some that look like images of muffins, and the 'food' class contains images of (you guessed it) fried chicken and muffins ?

Supported Tasks and Leaderboards

TBC

Languages

The labels are in English (['dog', 'food'])

Dataset Structure

Data Instances

A sample from the training set is provided below:

{
{'image': <PIL.JpegImagePlugin.JpegImageFile image mode=RGB size=300x470 at 0x7F176094EF28>, 
'label': 0}

}

Data Fields

• img: A PIL.JpegImageFile object containing the 300x470. image. Note that when accessing the image column: dataset[0]["image"] the image file is automatically decoded. Decoding of a large number of image files might take a significant amount of time. Thus it is important to first query the sample index before the "image" column, i.e. dataset[0]["image"] should always be preferred over dataset["image"][0]
• label: 0-1 with the following correspondence 0 dog 1 food

Data Splits

Dataset Creation

Curation Rationale

N/A

Source Data

This dataset was taken from the qw2243c/Image-Recognition-Dogs-Fried-Chicken-or-Blueberry-Muffins? Github repository, merging the 'chicken' and 'muffin' categories into a single 'food' category, and randomly splitting 10% of the data for validation.

Annotations

This data was scraped from the internet and annotated based on the query words.

Discussion of Biases

This dataset is imbalanced -- it has more images of food (2000) compared to dogs (1000), due to the original labeling. This should be taken into account when evaluating models.
