 **Detailed description**
 
-Taking a tensor with rank `N` as the first input `indices`, OneHot produces tensor with rank `N+1` extending original
-tensor with a new dimension at `axis` position in shape. Output tensor is populated with two scalar values: `on_value`
-that comes from the 3rd input and `off_value` that comes from the 4nd input. Population is made in the following way:

-When index element from `indices` is greater or equal to `depth`, it is a well-formed operation. In this case the corresponding row `output[..., i, ...]` is populated with `off_value` only for all `i` values.

 **Inputs**:
 
-* **1**: `indices`: input tensor of rank `N` with indices of any supported integer data type. Can be 0D. Required.
-* **2**: `depth`: scalar (0D tensor) of any supported integer type that specifies number of classes and the size of one-hot dimension.
-* **3**: `on_value`: scalar (0D tensor) of any type that is the value that the locations in output tensor represented by indices in input take.
-* **4**: `off_value`: scalar (0D tensor) of any type that is the value that the locations not represented by indices in input take.
+* **1**: `indices`: input tensor of type *T1* with non-negative indices, behavior for negative indices is undefined. Can be 0D. Required.
+* **2**: `depth`: positive scalar (0D tensor) of type *T1* that specifies the number of classes and thus the size of the one-hot dimension. Required.
+* **3**: `on_value`: scalar (0D tensor) of type *T2* that fills the locations in output tensor specified in `indices`. Required.

 **Outputs**:
 
-* **1** Output tensor of rank `N+1`, where `N` is a rank of input tensor `indices`. A new axis of the size `depth` is inserted at the dimension `axis`.
