Learn the NumPy trick for generating synthetic data that actually behaves like real data.

下图展示了一个有趣的现象：在法国斗牛犬的图像上添加一小块对抗性补丁后，VGG分类器竟然以极高的置信度将其判定为足球。Grad-CAM可视化清楚地显示，模型的注意力完全从狗身上转移到了那块补丁——一个精心构造的小扰动就足以劫持整个决策过程。

While running a CI workflow for one of my Python projects on GitHub, I noticed that the job that was running Python 3.13 on the current windows-latest image was failing. All other Python versions and ...

One of the long-standing bottlenecks for researchers and data scientists is the inherent limitation of the tools they use for numerical computation. NumPy, the go-to library for numerical operations ...

A handbag designer was sentenced to 18 months in prison for importing bags made of rare skins. The bags were made from caiman and python skin, both protected under international trade laws. Nancy ...

There is a phenomenon in the Python programming language that affects the efficiency of data representation and memory. I call it the "invisible line." This invisible line might seem innocuous at ...

Python is convenient and flexible, yet notably slower than other languages for raw computational speed. The Python ecosystem has compensated with tools that make crunching numbers at scale in Python ...
