Overview of Funnel Transformer
Funnel Transformer is a type of machine learning model designed to reduce the cost of computation while increasing model capacity for tasks such as pretraining. This is achieved by compressing the sequence of hidden states to a shorter one, saving the FLOPs, and re-investing them in constructing a deeper or wider model.
The proposed model maintains the same overall structure as Transformer, with interleaved self-attention and feed-forward sub-modules wrapped by r

What is FuseFormer?
FuseFormer is a video inpainting model that uses a feedforward network to enhance subpatch level feature fusion. It is based on specialized Transformer-based technology with novel Soft Split and Soft Composition operations. These operations divide the feature map of a video into small patches and then stitch them back together. This enhances the video's overall quality by improving the fine-grained feature fusion of the video.

The STEP network is trained on annotated real-world gait videos, as well as synthetic gaits generated using a networ
GAN Feature Matching: A Method for More Efficient Generative Adversarial Network Training
Introduction
Generative Adversarial Networks (GANs) are a type of machine learning model that has gained popularity in recent years for their success in generating realistic images, audio, and text. However, training these models can be difficult due to the tendency to overfit, which leads to poor quality generated outputs. Feature matching is a technique that helps to address this problem by preventing t
GAN Hinge Loss is a technique used in Generative Adversarial Networks (GANs) to improve their performance. GANs are a type of neural network that consists of two parts: a generator and a discriminator. The generator creates new data samples, and the discriminator determines whether a given sample is real or fake. The two parts are trained together in a loop until the generator produces samples that are indistinguishable from real data.

A loss function is a mathematical
The GAN Least Squares Loss is an objective function used in generative adversarial networks (GANs) to improve the accuracy of generated data. This loss function helps GANs improve the quality of generated data by making it more similar to real data. The method used for this is called the Pearson $\chi^{2}$ divergence, which is a measure of how different two distributions are from each other. It calculates the difference between the generated distribution and the real distribution, which helps th
