Notes for "Truncated Normal Distribution"

1. Definition

• A normal distribution restricting the range of value of variable $x$.

2. Significance

• The example calculation shows the reliability obtained under the trucated distribution at both end is more in line with the actual situation than that obtained under the theoreical distribution.

3. Implementation in tensorflow

        stddev: a python scalar or a scalar tensor. 
        Standard deviation of the random values to generate.
