目标是什么？只需挥动手掌即可控制鼠标光标。一旦启动程序，窗口将显示你的网络摄像头画面，并实时叠加手部骨架。你电脑上的光标会跟随你食指的移动而移动。这几乎就像隔空移物—你无需触碰任何物理设备，就能操控数字对象。

How chunked arrays turned a frozen machine into a finished climate model ...

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。

Abstract: In the Python world, NumPy arrays are the standard representation for numerical data and enable efficient implementation of numerical computations in a high-level language. As this effort ...

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 ...

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 ...
