    企业如何把“想法”变成“算法”自动执行业务流程?

    在构建系统中我们需要用到学习模型,那么我们常见学习模型对比和选择有9类: 1、有监督还是无监督(Supervised VS Unsupervised) 2、线性还是非线性 (Linear VS Non-Linear 线性还是非线性 Linear VS Non-Linear 如何把未知问题转化成已知问题, 如何把非线性转化成线性, 永远是很很需要的。

    I-LLM:首次实现了LLM全整形量化,精度逼近浮点,超过Smooth/Omini/AffineQuant

    我们认为LLMs integer-only量化的主要问题在于linear和non-linear计算时激活值中在跨channel和跨token维度上有巨大波动。 然而,这对于Linear层比较容易实现,但是对Non-linear算子不能直接进行等价变换。 Dynamic Non-Linear Integer-only Operations 由于DI-MatMul支持了动态量化,导致激活值的scale在运行时是变化的,因此我们也提出了DI-ClippedSoftmax
