Overview of Generalized Additive Models (GAM)
Generalized Additive Models (GAM) are a statistical method used to model the relationships between variables in a dataset. GAM allows us to explore nonlinear relationships between variables, which cannot be achieved using linear models. The method aims to identify the effect of each predictor variable and the outcome variable simultaneously by accounting for both linear and nonlinear relationships.
GAM is a powerful statistical tool that has been w
What is Generalized Focal Loss?
Generalized Focal Loss (GFL) is a loss function used in object detection. It combines two other loss functions, Quality Focal Loss and Distribution Focal Loss, into a generalized form that can be used to train machine learning models for detecting and classifying objects in images. Object detection is an important task in computer vision, and is used in a wide range of applications such as self-driving cars, security systems, and medical imaging. The goal is to i
What is Generalized Mean Pooling?
Generalized Mean Pooling (GeM) is a mathematical operation used in deep learning to compute the generalized mean of each channel in a tensor. It is a generalization of the average pooling, which is commonly used in classification networks, and of spatial max-pooling layer. By applying GeM, it is possible to increase the contrast of the pooled feature map and focus on the salient features of the image.

Reinforcement learning is a powerful technique in the field of artificial intelligence that enables an agent to learn from reward signals while interacting with an environment. One important aspect of reinforcement learning is exploration, or the ability of the agent to try out new actions in order to discover rewarding outcomes. One method of exploration is called Generalized State-Dependent Exploration, or gSDE.

GAIL stands for Generative Adversarial Imitation Learning. The concept of GAIL is based on extracting data policies directly from data rather than depending on a pre-defined reward function. This approach has similarities with inverse reinforcement learning (IRL) but does not require setting up a reward function. This article will explain GAIL, how it works, and its possible applications.

GAIL is a learning algorithm that combines reinforcement learning and imitation learning to
A Generative Adversarial Network, or GAN, is a type of AI model that is used for generating new images, texts, and even videos. Unlike other AI models that simply learn how to classify data, GANs train two different models: one that creates new data and another that can identify whether that data is real or fake.
How GANs Work
GANs work by training two deep neural networks – a generator and a discriminator – in a competition. The generator network creates samples, and the discriminator tries

Genetic Algorithms (GA) is a type of search algorithm that imitates the biological process of evolution. GA selects the best solution from a given set of solutions, just like nature selects the fittest organism from a set of organisms to propagate and evolve over time. This algorithm was first introduced by John Holland in the 1970s, and since then, its popularity has only increased.

Geomancer is an algorithm used to disentangle data manifolds. It is a nonparametric method that uses symmetry-based approaches to learn subspaces and assign them to each point in the given dataset. In other words, Geomancer helps to identify and separate different submanifolds within a dataset.
Unlike other methods, Geomancer works even if there is no global axis-aligned coordinate system for the data manifolds. Thus, it is ideal for disentangling complex data sets where it

The global-and-local attention (GALA) module is a mechanism used in computer vision that enables a neural network to focus on certain regions of an image more than others.
