精准macro avg=(P_no+P_yes)/2=(0.24+0.73)/2 = 0.48 3、加权平均 weighted avg: 是对宏平均的一种改进,考虑了每个类别样本数量在总样本中占比 精准weighted avg =P_no*(support_no/support_all)+ P_yes*(support_yes/support_all =0.24*(7525/29997)+0.73*(22462/29997)=0.61 如果每个class的样本...
Weighted Average 从计算的角度讲,先对每个类求值,再取平均得到Macro Average会比较容易.但是当数据集中存在严重类别不平衡的问题时,就不适宜单纯使用Macro Average.此时可以采取weighted average. 具体来说当我们计算Macro Average时候我们给每个类赋予相同的权重,但是当样本不平衡时,不适宜给每个类赋予同样的权重,我们可...

I am 5’2 and weighted 126 with 38.7% body fat . 4 months in and i lost 10 pounds. I’m on 116 right now with 32.4%. And it’s becoming frustrating for me not seeing so much results if I’ve been eating healthy . This calculator is giving me 84g of carbs, 24g protein and ...
Macro excel programming Please advise how to use macro excel to write a programme to calculate weighed average.
average is only useful for multilabel/multiclass. I have proven with above code: average is useful (and error-free) for binary. Given this, why do I get this error? In other wordsis it correctthat the "weighted" param throws an error when given binary targets?

Historically, equity performance one-to-two months before a US Presidential election has been poor (on average). Accordingly, we have downgraded equities from overweight to neutral and prefer to focus on relative value opportunities across asset classes. A less attractive risk-reward The bull case ...
