In response to this:

As we discussed previously: #2021 (comment) we want to add more AI/ML examples to the Kubeflow Training Operator. Right now, most of our examples have very basic and simple CNN training for MNIST. Since Training Operator is capable to train large-scale ML models, we would like to contribute more AI/ML use-cases.

We can make these examples Data Scientists friendly and re-use our Python SDK within Jupyter Notebooks to simplify the user submission.
I like the example structure of HF Transformers, so I propose the following path: examples/<framework>/<ml-use-case>

We can start with these examples (feel free to add more ML use-cases in this issue):

• Language Modeling
• Image Classification
• Text Classification
• Audio Classification
• Question Answering
• Speech Recognition
• Text Generation

We should investigate how to configure our CI/CD to make sure that these examples are functional.

@andreyvelich I love this. Few thoughts:

• Whenever we publish a new example, please reach out to me or Amber so that we can help turning it into either a short blog post or at least disseminate via social media.
• How do you define the actual use case for these topics?
• Are these examples supposed to be specific to the training operator or were you thinking of a wider applicability (serving, tuning, metadata, etc.)
