UnverifiedSpectrumQuant fills the gap between data-independent structured rotations and learned rotations, being both data-aware (using calibration data to estimate the covariance) and efficient (closed-form solution, no optimization required).76% similarUnverifiedThis framework decomposes answer quality into multiple independently evaluable dimensions; fine-grained signals can reduce the number of samples required for alignment and improve the multi-dimensional balance of the final model59% similarUnverifiedGenerative models leave regular grid-like artifacts in the Fourier frequency spectrum of images during operations such as upsampling and deconvolution, which can be detected through frequency domain transforms such as FFT.59% similarUnverifiedThe paper currently validates SpectrumQuant only on Llama and Mistral, and its performance under broader model architectures and quantization configurations still needs further observation.58% similarVerified反向传播算法的本质是通过链式法则在计算图上高效计算标量损失对每个参数的偏导数56% similar
