@AdamMiltonBarker Could you clarify your question some more?
from turicreate.
Hi @srikris thanks the quick reply, so regarding the docs on new observation data:
recommend() accepts new observation data. Currently, the ItemSimilarityModel makes the best use of this information.
m_item_sim = turicreate.item_similarity_recommender.create(data)
new_obs_data = turicreate.SFrame({'user_id' : ['Charlie', 'Charlie'],
'item_id' : ['Item1', 'Item5']})
recommendations = m_item_sim.recommend(['Charlie'], new_observation_data = new_obs_data)
Does this actually update the net with the new observation data, or is it just used to reference against and is then gone when the recommendation finishes? If this is the case, is there a way to train the network with new data but not have to retrain the entire network again from scratch, so I am describing online learning, but some people call it other things.

Sorry for the late response. No it does not update the data but it updates the predictions assuming this new data was seen so the effect is pretty close.

To add to the question of @AdamMiltonBarker, since the new_observation_data
doesn't update the model, what would be the recommended way to implement "online" updating of the model with new data?
Re-training the model from scratch, every once in a while, simply wouldn't work in real system, so we need a way to gradually update the learned weights & factors with new data samples.

It does not EVEN update forecasts. It would be great to get an improvement after a few years.
