Tīmeklis2024. gada 6. janv. · ah, this will be a problem, note, the problem isn't a lambda function per se, it's that pickle only likes to use module-level functions, here, the solution would be to use a higher order function, a function factory that takes those as an input and returns a corresponding function, but you'll be right back to where you started Tīmeklis可以这么理解Lambda，Lambda量化了一个待排序的文档在下一次迭代时应该调整的方向和强度。可以看出，LambdaRank不是通过显示定义损失函数再求梯度的方式对排序问题进行求解，而是分析排序问题需要的梯度的物理意义，直接定义梯度，可以反向推导出LambdaRank的损失函数为： L i j = log ⁡ {1 + exp ⁡ (s ...
