https://www.tensorflow.org/ transforms are the leading cause of most https://thenewstack.io/machine-learning/ model performance issues. These are but two of the lessons Etsy has learned deploying its new ML testing tool.

As the global online market develops deep learning models for its search ranking platform, the engineering team had to create automated testing practices to lower latencies.

The first was that most model performance issues were caused by slow TensorFlow transforms.

Etsy determined that this issue was workload specific because while “features transmission” time wasn’t linear with payload size on a request level, search rankings shrugged from this issue while ads rankings didn’t.
