math.attention-mechanism Calculator
Calculates the scaled dot-product attention mechanism output (softmax(QK^T/√d)V) for given query, key, and value sequences. The attention mechanism is the core innovation of the Transformer architecture — this makes its matrix mathematics concrete.
Inputs
Query Dim
Reference formula or conversion factor shown for context.
Sequence Length
Linear measurement. Ensure consistent units: 1 m = 1,000 mm = 3.281 ft.
Temperature
Thermal state of the substance. Check whether the formula needs Celsius, Fahrenheit, or Kelvin (K = °C + 273.15).
Results
attention scale factor
A dimensionless multiplier applied in the calculation.
total attention FLOPs
The combined total across all inputs and components.
QKV memory (bytes)
Voltage in kilovolts (kV). 1 kV = 1,000 V. Used for high-voltage transmission lines and industrial equipment.
score = QK^T / sqrt(d_k)
A numerical rating from the scoring model in use.
complexity O(n²d)
Algorithmic complexity class (e.g. O(n), O(n log n), O(n^2)). Determines how runtime or memory scales with input size.
