Maps a federated value pointwise using a mapping function.
tff.federated_map(
fn, arg
)
The function fn is applied separately across the group of devices
represented by the placement type of arg. For example, if value has
placement type tff.CLIENTS, then fn is applied to each client
individually. In particular, this operation does not alter the placement of
the federated value.
Args |
|---|
fn
|
A mapping function to apply pointwise to member constituents of arg.
The parameter of this function must be of the same type as the member
constituents of arg.
|
arg
|
A value of a TFF federated type (or a value that can be implicitly
converted into a TFF federated type, e.g., by zipping) placed at
tff.CLIENTS or tff.SERVER.
|
Returns |
|---|
A federated value with the same placement as arg that represents the
result of fn on the member constituent of arg.
|
Raises |
|---|
TypeError
|
If the arguments are not of the appropriate types.
