Class GRUCellOp

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

Represents a GRU (Gated Recurrent Unit) cell operation in the IR.

public class GRUCellOp : IROp
Inheritance
GRUCellOp
Inherited Members

Remarks

GRU cell computes: - z = sigmoid(Wz @ x + Uz @ h + bz) // Update gate - r = sigmoid(Wr @ x + Ur @ h + br) // Reset gate - h_tilde = tanh(Wh @ x + Uh @ (r * h) + bh) // Candidate hidden state - h_new = (1 - z) * h + z * h_tilde // New hidden state

Properties

HasBias

Whether to include bias terms.

public bool HasBias { get; set; }

Property Value

bool

HiddenSize

Size of the hidden state.

public int HiddenSize { get; set; }

Property Value

int

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.
