Runs an image classifier trained with SimCLR contrastive learning and few labels, from the Keras team, in a Gradio page with example images. For machine learning learners and researchers. Semi-Supervised Contrastive Learning with SimCLR is a kit in the Research category, listed by Mindket. It is free. This is version 1, last updated on 2026-11-13. Download it on this page, a zip of its files. Nothing in it runs by itself. Made by keras-io ## About ### What it is This Gradio app runs an image classifier built with semi-supervised contrastive learning, using the SimCLR method. The record names one model, semi-supervised-classification-simclr, from the keras-io group. An examples folder holds sample images. ### Who it suits It suits machine learning learners and researchers who want to try a model trained with only some labeled data, and developers who want a small Gradio demo around a Keras model. The record does not list the classes or the dataset. | Industry | Who uses it | How they use it | Example | | --- | --- | --- | --- | | Research | Vision researchers | Try a model trained with few labels | Run an example image and read the prediction | | Education | Machine learning students | See what semi-supervised training can produce | Compare predictions across several examples | | Software | Python developers | Read a small Gradio demo around a Keras model | Open app.py and requirements.txt | You can skip it if you need a model with documented classes and accuracy. ### Where to use it - A web browser, on the Space's page on Hugging Face - Windows, macOS or Linux with Python, from a downloaded copy | Use case | Who | What they get back | | --- | --- | --- | | Classify an example image | Learners | The model's predicted label | | Try the bundled examples | Anyone | A quick sense of how the model behaves | | Reuse as a base | Developers | A small Gradio app around a Keras model | ### How to set it up - Nothing at all if you use the online Space - Python on your computer, only if you run a copy - The packages listed in requirements.txt 1. Open the Space's page in a browser to use it with nothing to install. 2. To run a copy, install the Hugging Face Hub package and download the Space. 3. Move into the new folder, then install Gradio and the listed requirements. 4. Start the app with Python. ```sh pip install -U huggingface_hub hf download keras-io/semi-supervised-classification --repo-type space --local-dir semi-supervised-classification cd semi-supervised-classification pip install gradio pip install -r requirements.txt python app.py ``` ### How to use it Online, open the Space and use the controls on its page. On your own machine, run the main file from the Space folder, then use the page it serves. The example images are the quickest way to try it. ```sh python app.py ``` ### Example You open the Space and pick one of the example images. The app returns the label the model predicts for it. The record does not describe the output, so look at the page. ### For newcomers and experts Labeling images by hand is costly. Semi-supervised training uses a small set of labeled images together with many unlabeled ones. Start by opening the Space and running an example image. If you know the field, SimCLR trains an encoder by pulling together two altered views of the same image and pushing apart views of different images. A classifier is then fitted on few labels. The record gives no dataset, label counts or accuracy figures. You pick or upload an image → The Gradio page sends it to app.py → The trained encoder and classifier process it → The page shows the predicted label ### Good to know - License: Apache 2, as listed on the Space - Cost to run: none named - Data it reaches: the images you give it and the model it names - Not for: the record names no exclusions, and it gives no dataset or accuracy figures ## README ````markdown # Semi-Supervised Contrastive Learning with SimCLR Runs an image classifier trained with SimCLR contrastive learning and few labels, from the Keras team, in a Gradio page with example images.
