Remarks
Computes Sign(x) = -1 if x < 0, 0 if x == 0, 1 if x > 0. Hard threshold activation, commonly used in binary networks.
Methods
Validate()
Validates that this operation is correctly formed.
public override bool Validate()Returns
- bool
True if valid, false otherwise.
Remarks
Basic validation checks that the operation has required information. Derived classes can override to add operation-specific validation.
For Beginners: This checks that the operation makes sense.
Basic checks:
- Output ID is valid (non-negative)
- Has the right number of inputs
- Shapes are compatible
Specific operations add their own checks:
- MatMul: inner dimensions must match
- Conv2D: kernel size must be valid
- Reshape: total elements must be preserved
If validation fails, the operation can't be compiled.
