The article "Real-World Examples of 0D, 1D, 2D, 3D, 4D and 5D Tensors" from the "Neural Networks and Deep Learning Course" introduces the concept of tensors as fundamental data structures in machine learning and deep learning.

Apr 29, 2018 · We view drawings or photographs on flat paper or computer screens. Even our 3-D visual observation of the world around us is based on 2-D images flashed onto our retinas at the back of our eyes. But two dimensions is not the minimal limit. Images can also be …

Key difference: The terms 2D, 3D, and 4D stand for two-dimensional, three-dimensional and four-dimensional respectively. They are named for the number of dimensions that they portray. 2D represents an object in just two dimensions, while 3D represents it in three dimensions.

Dec 14, 2022 · We've seen 1D and 2D tensors; below is an example of a 3D tensor. Its shape is (2, 2, 3) because the outermost brackets have two 2D tensors, hence the first 2 in (2, 2, 3). Both 2D tensors within are of shape (2, 3), hence the second 2 and the 3 you see in the shape (2, 2, 3).

Four-dimensional space (4D) is the mathematical extension of the concept of three-dimensional space (3D). Three-dimensional space is the simplest possible abstraction of the observation that one needs only three numbers, called dimensions, to describe the sizes or locations of objects in the everyday world.

Jul 3, 2024 · 3D Medical Images: In medical imaging, a 5D tensor can represent a batch of 3D scans where each scan is a volume with height, width, and depth dimensions. Shape: (n, t, d, m, p), where n is the...

Nov 25, 2020 · Dimensions (0D, 1D, 2D, 2.5D, 3D & 4D) Geometry defines a dimension as the number of coordinates needed to specify a point on the object. (“The Differences Between 1D, 2D & 3D Pictures”, 2018)

Feb 12, 2025 · Painters use the technique of perspective, drawing distant objects smaller and depicting angles as visible through one’s point of view, while 3-D movies use two images superimposed on the same screen.

For example, a set of 1000, 640 x 480 pixel black and white images would be represented as 4D Tensor of Shape [1000, 640, 480, 1]. Summary Tensors are just buckets of numbers of a specific shape and a certain rank (dimensionality).
