[Task] Transformer-Based End-To-End Example with TensorFlow Merlin Models

[viswa-nvidia]

This ticket is to provide and End-To-End example in Merlin Models for a transformer-based model.

We will add serving to https://github.com/NVIDIA-Merlin/models/blob/main/examples/usecases/transformers-next-item-prediction.ipynb . @radekosmulski started a PR, but we are blocked on the implementation #1045

@marcromeyn @viswa-nvidia can you provide the dependency for the tickets? Which other tickets need to be finished that we can provide the example?

[bschifferer]

What do we want to demonstrate? Is this the Transformer4Rec examples in Merlin Models with Tensorflow instead of PyTorch? Do we need any other system components (e.g. candidate retrieval, feature store)?

Updating RecSys2022 with Transformer4Rec

[bschifferer]

Merlin Models Examples - Transformer4Rec Examples:
Repository Merlin/models:

• Updating RecSys2022 with Transformer4Rec ([Task] Updating RecSys2022 with Transformer4Rec #810)

Repository Merlin/Merlin

• UseCase # 1: Low number of items (<2000 items) - direkt ranking (training+serving)
• UseCase # 2: More Items - extract embeddings and use ANN (training+serving) ([Task] Transformer-session-based End2End Example with Merlin Models and Merlin Systems Merlin#694)

Dataset - TBD:
Potential: dressipi, h&m, ecommerce, booking.com?
