Python is used in all kinds of different contexts, and its versatility and ease of use has made it attractive to many. There are tons packages for all sorts of tasks, and the huge community and its open development help the enormous success of Python. In the world of scientific computing,...
For Galerkin projection, the reduced space–time system matrix A ^ s t , g ( μ ) involves matrix multiplication twice. The first operation is matrix multiplication of n s n t × N s N t matrix and N s N t × N s N t lower triangular matrix with bandwidth N s . Then, the ...

对于代码特征,原论文提取了函数名、调用API序列和token集;对于描述文字,通常选取docstring(Python)或函数上方或内部注释(JavaScript)。对于函数名、token集,会按照驼峰命名和下划线命名进一步划分成更小的词法单元,而API序列则保留不再分割。 所有的这些词素,对于有序的会使用RNN或其变种处理,再将RNN每一个词的输出进行...
新建Python代码文件 qrcode.py,引入需要的库: # qrcode.pyfromPILimportImage, ImageDraw 为了思维简便,我们自顶向下地构建代码。首先,假设我们已经填充好了一个QR码的矩阵bitmap,我们需要把相应的图像生成出来。这里就有了图像大小的问题:Version 1 的QR码表示为 21×21 的矩阵,直接把这个矩阵当做位图来输出的话...
Recall in VAE we would like the image encodings to be as close as possible to each other while still be unique, allowing for the generation of samples that looks similar to the real ones with smooth interpolation in the latent space. To achieve all of this we introduce a new loss function...
