SigComp, an integer-quantized multilayer perceptron compressor for nanopore signal deltas, reduces compressed file sizes by 6.00%-7.09% over VBZ while remaining bit-exact.
- Why it matters: Existing model-free compressors like VBZ and ex-zd miss higher-order statistical dependencies, and floating-point neural compressors can be too slow and non-deterministic for large nanopore datasets.
- What they did: SigComp uses a compact multilayer perceptron with a fixed 64-symbol context window over one-byte signal deltas, combined with post-training quantization and a fully GPU-native range coder.
- The result: Across diverse species and chemistries (DNA R10.4.1 and RNA004), SigComp achieves 6.00%-7.09% smaller files than VBZ and 3.86%-5.34% smaller than ex-zd, with 46-74× higher throughput than the leading neural compressor.
