- Method Detail
  - init
```
void init(java.lang.String parameterId,
          NDArray[] value)
```
    Initializes the ParameterStore for the given parameter.
    
    Parameters:
    
    parameterId - the parameter ID
    
    value - the values to be set for the given parameter
  - update
```
default void update(java.lang.String parameterId,
                    NDArray[] params)
```
    Updates the parameter of a key from Parameter Server.
    
    Parameters:
    
    parameterId - the key to identify the parameter
    
    params - the parameter NDArrays in different devices to be updated.
  - update
```
void update(java.lang.String parameterId,
            NDArray[] grads,
            NDArray[] params)
```
    Updates the parameter of a key from Parameter Server.
    
    Parameters:
    
    parameterId - the key to identify the parameter
    
    grads - the gradient NDArrays in different devices to apply the update.
    
    params - the parameter NDArrays in different devices to be updated.
