    scale,

    validate_args=False,

)

Defined in tensorflow/contrib/distributions/python/ops/poisson_lognormal.py.

Use LogNormal quantiles to form quadrature on positive-reals.

Args:

  • loc: float-like (batch of) scalar Tensor; the location parameter of the LogNormal prior.
  • scale: float-like (batch of) scalar Tensor; the scale parameter of the LogNormal prior.
  • quadrature_size: Python int scalar representing the number of quadrature points.
  • validate_args: Python bool, default False. When True distribution parameters are checked for validity despite possibly degrading runtime performance. When False invalid inputs may silently render incorrect outputs.
  • name: Python str name prefixed to Ops created by this class.

Returns:

  • grid: (Batch of) length-quadrature_size vectors representing the log_rate parameters of a Poisson.
  • probs: (Batch of) length-quadrature_size vectors representing the weight associate with each grid value.
