Understanding GPSA and its Significance in Vision Transformers
In the world of computer vision, convolutional neural networks (CNNs) have revolutionized the way image classification and segmentation are done. However, recently, a new type of neural network has emerged, known as the Vision Transformer (ViT). These are neural networks that rely not on convolutional layers but on self-attention mechanisms, which have been shown to provide better results on a variety of image classification tasks.
A Gated Recurrent Unit, or GRU, is a type of recurrent neural network that is commonly used in deep learning research. GRUs are similar to Long Short-Term Memory (LSTM) networks, which are also recurrent neural networks, but have fewer parameters, making them easier to train and faster to compute.

What is Gaussian Affinity?
Gaussian Affinity is a mathematical concept used in machine learning and data analysis. It is a type of self-similarity function that measures the similarity between two data points. Gaussian Affinity is based on a Gaussian function which uses the dot-product similarity between the two data points.
How does Gaussian Affinity work?
The Gaussian Affinity between two points, $\mathbb{x\_{i}}$ and $\mathbb{x\_{j}}$, is calculated using the following formula:

What are Gaussian Processes?
Introduction to Gaussian Processes
Gaussian Processes are a type of statistical model that can be used to approximate functions. Unlike some other models, Gaussian Processes are non-parametric — which means that they don't make any assumptions about the shape of the underlying function they are modeling. Instead, they rely on a measure of similarity between points (called the kernel function) to make predictions about the value of an unseen data point based on the
What is GBlock?
GBlock is a type of residual block that is used in the GAN-TTS text-to-speech architecture. The purpose of GBlock is to assist the generator in producing raw audio, with the receptive field of G large enough to capture long-term dependencies. In a GBlock, dilated convolutions are used to ensure the audio sequence contains 48000 samples, or a 2s training clip.
How Does GBlock Work?
A GBlock is a stack of two residual blocks. There are four kernel size-3 convolutions used in ea
What is Gradient-Based Subword Tokenization?
Gradient-Based Subword Tokenization (GBST) is a method of automatically learning latent subword representations from characters. It is a soft gradient-based subword tokenization module that uses a block scoring network to score candidate subword blocks. GBST is a data-driven approach that enumerates subword blocks and learns to score them position-wise.
The scoring network scores each candidate subword block and learns a position-wise soft selection
