 **Detailed description**: For each element from the input tensor calculates corresponding
 element in the output tensor with the following formula: 
 
-    \f[
-    HSigmoid(x) = \frac{min(max(x + 3, 0), 6)}{6}
-    \f]
+\f[
+HSigmoid(x) = \frac{min(max(x + 3, 0), 6)}{6}
+\f]
 
 The HSigmoid operation is introduced in the following [article](https://arxiv.org/pdf/1905.02244.pdf).
