What is Gradual Self-Training?
Gradual self-training is a machine learning method for semi-supervised domain adaptation. This technique involves adapting an initial classifier, which has been trained on a source domain, in such a way that it can predict on unlabeled data sets that experience a shift gradually towards a target domain. This approach has numerous potential applications in domains like self-driving cars and brain-machine interfaces, where machine learning models must adapt to chang

Graph Attention Networks (GATs) are a type of neural network used for processing graph data, which is data with complex relationships. GATs use attention mechanisms to focus on the most relevant nodes in a graph when making predictions. However, the standard GAT layer has a "static attention problem" where the ranking of attended nodes is unconditioned on the query node. This is where GATv2 comes in.
What is GATv2?
GATv2 is an operator introduced in the "How Attentive are Graph Attention Netw
Graph Attention Network (GAT): A Revolutionary Neural Network Architecture
Artificial Intelligence (AI) works on a simple mechanism of feeding data into a neural network-based system, following steps, patterns, and historical data to give an output. However, traditional machine learning (ML) models operate on data points that are not usually interlinked. At the same time, real-world data presents a much more complex problem in the form of networks with different relations between data points. G

Social media has become a major news source for millions of people around the world due to its low cost, easy accessibility, and rapid dissemination. However, this comes at the cost of dubious trustworthiness and a significant risk of exposure to fake news, intentionally written to mislead the readers. Detecting fake news is a challenge that is difficult to overcome using existing content-based analysis approaches. One of the main reasons for this is that often the interpretat

What is a Graph?
First, let’s make sure we all understand what we mean by a graph. In mathematics, a graph is a way of representing relationships between objects. It is made up of vertices (also called nodes) and edges. A vertex can represent anything, from a person to a city to a gene, and
GFSA or Graph Finite-State Automaton is a layer that can be used for learning graph structure. This layer is differentiable, which means it can be trained end-to-end to add derived relationships or edges to arbitrary graph-structured data. GFSA works by adding a new edge type, expressed as a weighted adjacency matrix, to a base graph. This layer has been designed to be used in machine learning applications.
