Fashion-MNIST Dataset

The Fashion-MNIST dataset is a database of Zalando's article images—consisting of a training set of 60,000 examples and a test set of 10,000 examples. Each example is a 28x28 grayscale image, associated with a label from 10 classes. Fashion-MNIST is intended to serve as a direct drop-in replacement for the original MNIST dataset for benchmarking machine learning algorithms.

Key Features

Fashion-MNIST contains 60,000 training images and 10,000 testing images of Zalando's article images.
The dataset comprises grayscale images of size 28x28 pixels.
Each pixel has a single pixel-value associated with it, indicating the lightness or darkness of that pixel, with higher numbers meaning darker. This pixel-value is an integer between 0 and 255.
Fashion-MNIST is widely used for training and testing in the field of machine learning, especially for image classification tasks.

Dataset Structure

The Fashion-MNIST dataset is split into two subsets:

Training Set: This subset contains 60,000 images used for training machine learning models.
Testing Set: This subset consists of 10,000 images used for testing and benchmarking the trained models.

Labels

Each training and test example is assigned to one of the following labels:

T-shirt/top
Trouser
Pullover
Dress
Coat
Sandal
Shirt
Sneaker
Bag
Ankle boot

Applications

The Fashion-MNIST dataset is widely used for training and evaluating deep learning models in image classification tasks, such as Convolutional Neural Networks (CNNs), Support Vector Machines (SVMs), and various other machine learning algorithms. The dataset's simple and well-structured format makes it an essential resource for researchers and practitioners in the field of machine learning and computer vision.

Usage

To train a CNN model on the Fashion-MNIST dataset for 100 epochs with an image size of 28x28, you can use the following code snippets. For a comprehensive list of available arguments, refer to the model Training page.

FAQ

What is the Fashion-MNIST dataset and how is it different from MNIST?

The Fashion-MNIST dataset is a collection of 70,000 grayscale images of Zalando's article images, intended as a modern replacement for the original MNIST dataset. It serves as a benchmark for machine learning models in the context of image classification tasks. Unlike MNIST, which contains handwritten digits, Fashion-MNIST consists of 28x28-pixel images categorized into 10 fashion-related classes, such as T-shirt/top, trouser, and ankle boot.

How can I train a YOLO model on the Fashion-MNIST dataset?

To train an Ultralytics YOLO model on the Fashion-MNIST dataset, you can use both Python and CLI commands. Here's a quick example to get you started:

!!! Example "Train Example"

=== "Python"

    ```python
    from ultralytics import YOLO

    # Load a pretrained model
    model = YOLO("yolov8n-cls.pt")

    # Train the model on Fashion-MNIST
    results = model.train(data="fashion-mnist", epochs=100, imgsz=28)
    ```


=== "CLI"

    ```bash
    yolo classify train data=fashion-mnist model=yolov8n-cls.pt epochs=100 imgsz=28
    ```
