对于习惯使用 PyTorch 或 TensorFlow 的用户来说，调用 nn.LSTM 虽然高效，但也屏蔽了最核心的数学推导，结果代码写了好几年，loss 是怎么传回去的，脑子里还是一团浆糊。

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

Abstract: UltraFlex is an iterative model-based ultrasonic flexible-array shape calibration framework that uses automatic differentiation. This work evaluates array shape calibration model performance ...

Marc Santos is a Guides Staff Writer from the Philippines with a BA in Communication Arts and over six years of experience in writing gaming news and guides. He plays just about everything, from ...

In Numpy the direct setting of the dtype, shape and strides attributes is being deprecated as these operations are not safe (in particular in the free-threading build). See numpy/numpy#28800 for ...

When a 1-dimensional Numpy array that only has 1 entry is stored to a DataFrame, Pandas seems to automatically make it a 0-dimensional array. NOTE: This was not an issue in Pandas 2.0.0, but it is in ...

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 ...

Abstract: In this paper, an array shape calibration method for a planar sensor array is proposed. A sensor array is used for array signal processing that is a technique for direction of arrival (DOA) ...
