tf.raw_ops.ResourceApplyProximalAdagrad

Update 'var' and 'accum' according to FOBOS with Adagrad learning rate.

tf.raw_ops.ResourceApplyProximalAdagrad(
    var, accum, lr, l1, l2, grad, use_locking=False, name=None
)

accum += grad * grad prox_v = var - lr * grad * (1 / sqrt(accum)) var = sign(prox_v)/(1+lr*l2) * max{|prox_v|-lr*l1,0}

Args

var A Tensor of type resource. Should be from a Variable(). accum A Tensor of type resource. Should be from a Variable(). lr A Tensor. Must be one of the following types: float32, float64, int32, uint8, int16, int8, complex64, int64, qint8, quint8, qint32, bfloat16, qint16, quint16, uint16, complex128, half, uint32, uint64. Scaling factor. Must be a scalar. l1 A Tensor. Must have the same type as lr. L1 regularization. Must be a scalar. l2 A Tensor. Must have the same type as lr. L2 regularization. Must be a scalar. grad A Tensor. Must have the same type as lr. The gradient. use_locking An optional bool. Defaults to False. If True, updating of the var and accum tensors will be protected by a lock; otherwise the behavior is undefined, but may exhibit less contention. name A name for the operation (optional).
