因此如果你需要绘制某种类型的图,只需要在这个页面中浏览/复制/粘贴一下,基本上都能搞定。 在Linux下比较著名的数据图工具还有gnuplot,这个是免费的,Python有一个包可以调用gnuplot,但是语法比较不习惯,而且画图质量不高。 而Matplotlib则比较强:Matlab的语法、python语言、latex的画图质量(还可以使用内嵌的latex引擎绘制...

There are many data visualization libraries in Python, yet Matplotlib is the most popular library out of all of them. Matplotlib’s popularity is due to its reliability and utility - it's able to create both simple and complex plots with little code. You can also customize the plots in a...
3.5. Loss function Predicting users' ratings of items is a regression problem, and under the prior condition that the prediction error satisfies a Gaussian distribution, we use the following mean squared error (MSE) function. LOSS=1|R|∑(u,i,rui)∈R(rui−r^ui)2+λ||W||2 (9) R de...
