Python log Examples

Example #1

 def reduce_log_sum_exp(unused_ctx, data, axes=None, keepdims=1):
     if axes is None:
         axes = range(data.shape.ndims)
     if not isinstance(axes, (list, tuple)):
         axes = tuple(axes)
     return (op.log(op.summation(op.exp(data), axes=axes,
                                 keepdims=keepdims)), )

Example #2

 def softplus(data):
     return (op.log(op.exp(data) + 1.), )

Example #3

 def log(x):
     return (op.log(x), )

Example #4

 def log(unused_ctx, x):
     return (op.log(x), )

Example #5

 def softplus(unused_ctx, data):
     return (op.log(op.exp(data) + 1.), )
