Is the ALS model markovian?

bearrito — Fri, 16 Sep 2022 15:15:14 GMT

I didn't know how else to term this, I know ALS isn't but was curious about its represenation on disk.

If I wanted to backup(ship) a computed model, is it sufficent to store(ship) all the files in the latest successful generation only?

Use case are :

1. sending computed models to small clusters that only serve.

2. We have long-running but not eternally persistent clusters, I'd like to be able to ship a model from one to another. Or store it and then load and be able to continue computing without necessarily having generations N-1.

Ha, you mean is it memoryless? Yes. You can just ship the whole generation directory around. To roll back generations, just delete newer ones and restart the serving layer. etc.

Thanks, that actually makes sense as we have control over the model.generations.keep.
