Dynamic convolution is a novel operator design that increases the representational power of lightweight CNNs, without increasing their computational cost or altering their depth or width. Developed by Chen et al., dynamic convolution uses multiple parallel convolution kernels, with the same size and input/output dimensions, in place of a single kernel per layer.

The different convolution kernels in dynamic convolution are generated attention weights through a squ
What is Grouped Convolution?
A Grouped Convolution is a type of convolutional neural network (CNN) that uses multiple kernels per layer, resulting in multiple channel outputs per layer. The main purpose of using Grouped Convolutions in a neural network is to make the network learn a varied set of low-level and high-level features. This leads to wider networks that are better at recognizing different types of data.
The History of Grouped Convolution
The idea of using Grouped Convolutions was

Explaining LightConv at an 8th Grade Level
LightConv is a way to analyze sequences of data, like music, speech, or text, to understand patterns and predict what comes next. It does this by breaking the sequence down into smaller parts, called channels, and looking at how those parts interact with each other.
One of the key things that makes LightConv different from other methods is that it has a fixed context window. That means it only looks at a certain number of parts at a time, rather than
Masked Convolution is a type of convolution that is used for image generation models.

In the world of convolutional neural networks (CNNs), there is a type of convolution called depthwise convolution. A depthwise convolution applies a single kernel size to all channels. However, a new and more innovative type of convolution has been developed and is called MixConv or Mixed Depthwise Convolution. This type of convolution mixes up multiple kernel sizes in a single convolution and is based on the insight that depthwise convolut
Octave Convolution (OctConv) is a method that reduces the memory and computation cost of storing and processing feature maps that vary spatially "slower" at a lower spatial resolution.

The motivation behind Octave Convolution is that in natural ima
Pointwise Convolution is a method used in image processing that involves a small kernel, known as a 1x1 kernel which iterates through every single point of an image.
