LI Guobao updated SYSTEMML-2299:
--------------------------------
Description: The objective of “paramserv” built-in function is to update an
initial or existing model with configuration. An initial function signature
would be _model'=paramserv(model, X, y, X_val, y_val, upd=fun1, mode=SYNC,
freq=EPOCH, agg=fun2, epochs=100, batchsize=64, k=7, checkpointing=rollback)_.
We are interested in providing the model (which will be a struct-like data
structure consisting the weights, the biases and the hyperparameters), the
training features and labels, the validation features and labels, the batch
update function, the update strategy (e.g. sync, async, hogwild!,
stale-synchronous), the update frequency (e.g. epoch or mini-batch), the
gradient aggregation function, the number of epoch, the batch size, the degree
of parallelism as well as the checkpointing strategy (e.g. rollback recovery).
And the function will return a trained model in struct format. (was: The
