Computes log(cumsum(exp(x))). (deprecated)
tfp . math . log_cumsum_exp (
x , axis =- 1 , name = None
)
Deprecated: THIS FUNCTION IS DEPRECATED. It will be removed after 2023-03-01.
Instructions for updating:
log_cumsum_exp
is deprecated; Use tf.math.cumulative_logsumexp
instead.
This is a pure-TF implementation of tf.math.cumulative_logsumexp
; unlike
the built-in op, it supports XLA compilation. It uses a similar algorithmic
technique (parallel prefix sum) as the built-in op, so it has similar numerics
and asymptotic performace. However, this implemenentation currently has higher
overhead, so it is significantly slower on smaller inputs (n < 10000
).
Args
x
the Tensor
to sum over.
axis
int Tensor
axis to sum over.
name
Python str
name prefixed to Ops created by this function.
Default value: None
(i.e., 'cumulative_logsumexp'
).
Returns
cumulative_logsumexp
Tensor
of the same shape as x
.
