Class ScalarConstantOp

Namespace
AiDotNet.JitCompiler.IR.Operations
Assembly
AiDotNet.dll

Represents a scalar constant in the IR (single value).

public class ScalarConstantOp : IROp
Inheritance
ScalarConstantOp
Inherited Members

Remarks

ScalarConstantOp is a specialized version of ConstantOp for single values. It's more efficient for storing scalar values used in operations.

For Beginners: A ScalarConstantOp holds a single number.

Examples:

  • Learning rate: 0.001
  • Epsilon for numerical stability: 1e-7
  • Scale factor: 2.0

These are used in operations like:

  • result = input * 0.001 (scaling by learning rate)
  • result = input + 1e-7 (adding epsilon)

Properties

Value

Gets or sets the scalar value.

public double Value { get; set; }

Property Value

double

Methods

ToString()

Gets a string representation of this operation for debugging.

public override string ToString()

Returns

string

A string describing this operation.

Remarks

The string format is: "tOutput = OpType(tInput1, tInput2, ...) : Type [Shape]"

For Beginners: This creates a readable description of the operation.

Example outputs:

  • "t2 = Add(t0, t1) : Float32 [3, 4]"
  • "t5 = MatMul(t3, t4) : Float32 [128, 256]"
  • "t8 = ReLU(t7) : Float32 [32, 128]"

This is super helpful for debugging - you can see exactly what each operation does and what shape tensors flow through the graph.

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.
