+"""Pattern-Based Q/DQ Autotuning for ONNX Models.
+
+This package provides automated optimization of Quantize/Dequantize (Q/DQ) node placement
+in ONNX computation graphs to minimize TensorRT inference latency. It uses pattern-based
+region analysis to efficiently explore and optimize Q/DQ insertion strategies.
