成功解决coordinate_descent.py:491: ConvergenceWarning: Objective did not converge. You might want to inc

简介: 成功解决coordinate_descent.py:491: ConvergenceWarning: Objective did not converge. You might want to inc

解决问题


coordinate_descent.py:491: ConvergenceWarning: Objective did not converge. You might want to increase the number of iterations. Fitting data with very small alpha may cause precision problems.

ConvergenceWarning)



解决思路


coordinate_descent。收敛警告:目标未收敛。您可能希望增加迭代的次数。用非常小的alpha值拟合数据可能会导致精度问题。收敛警告)



解决方法


此信息提示为警告,即使不处理也不会影响代码编程。如果想要去掉,可以根据提示采用改进的方法!

目标未收敛,可以通过增加迭代的次数。或者用非常小的alpha值,进行拟合数据,但是这也可能会导致精度的准确性!

FPT: Feature Pyramid Transfomer
本文介绍了一个在空间和尺度上全活跃特征交互(fully active feature interaction across both space and scales)的特征金字塔transformer模型,简称FPT。该模型将transformer和Feature Pyramid结合,可用于像素级的任务,在论文中作者进行了目标检测和实力分割,都取得了比较好的效果。为了讲解清楚,若有transformer不懂的读者,关于transformer可以在公众号中看另一篇文《Transformer解读》

Objective-C 不是你想的那样
Ruby 和 Objective-C 这两种语言看上去好像天南地北:一种是动态语言,另一种则是静态语言;一种是解释型语言,另一种是编译型语言;一种有简洁的语法,另一种则是有点冗长的语法。从优雅的角度来看,Ruby似乎更能给我们一种自由的编程体验,所以很多人都放弃了Objective-C。
