Artificial intelligence

Stereotyping

Stereotyping refers to the simplified and fixed idea of a particular type of person or thing, based on general and often exaggerated characteristics. In the context of artificial intelligence (AI)…

Graphics, games and extended reality

Stereo Vision

Stereo vision is a technique used to extract three-dimensional (3D) information from two or more images captured from different angles or viewpoints. This process is based on the principle of human…

Engineering and transportation

Stern Drive

Stern drive is a propulsion system located at the rear of a boat, designed to provide the necessary force to move the vessel through the water. This type of propulsion typically involves a…

Engineering and transportation

Stern line

The stern line is a nautical term that refers to a rope or cable used to secure the stern of a boat. This line is essential in mooring maneuvers, as it provides stability and control to the vessel…

Engineering and transportation

Stern Post

The stern post is an essential structural component at the rear of a boat, known as the stern. This vertical member rises at the stern and primarily serves to support the transom, which is the flat…

Engineering and transportation

Stern Thruster

The stern thruster is an essential device in the maneuvering of vessels, specifically designed to facilitate the lateral movement of a ship's stern. This system allows captains and crews to perform…

Stimulation

Stimulation in the context of neuromorphic computing refers to the act of applying a stimulus to a system designed to mimic the functioning of the human brain. This process is fundamental for…

Artificial intelligence

Stitching

Stitching in the context of image processing refers to the process of combining multiple images to create a cohesive panorama. This method is fundamental in creating large images or capturing scenes…

Artificial intelligence

Stochastic

The term 'stochastic' refers to processes that are determined randomly, incorporating elements of randomness in decision-making. In the context of reinforcement learning and recurrent neural…

Blockchain and Web3

Stochastic Consensus

Stochastic consensus is a consensus mechanism that uses randomness as a key component to reach an agreement among distributed nodes in a system. This approach is especially relevant in environments…

Artificial intelligence

Stochastic Gradient

Stochastic gradient is an optimization method used in the field of machine learning. This approach is based on the idea that instead of calculating the gradient of the loss function using the entire…

Artificial intelligence

Stochastic Gradient Descent

Stochastic Gradient Descent (SGD) is an iterative method used to optimize objective functions expressed as the sum of differentiable functions. Unlike classical gradient descent, which uses the…

Data and analytics

Stochastic Graph

A stochastic graph is a type of graph where the existence of edges between nodes is determined by a probability distribution. This means that instead of having a fixed and deterministic structure…

Artificial intelligence

Stochastic Modeling

Stochastic modeling is an analytical approach that incorporates randomness and unpredictability into the systems being studied. Unlike deterministic models, which assume that outcomes are predictable…

Artificial intelligence

Stochastic Neighbor Embedding

Stochastic Neighbor Embedding (t-SNE) is a non-linear dimensionality reduction technique that allows for the visualization of high-dimensional data by embedding it into a lower-dimensional space…

Mathematics and statistics

Stochastic Optimization

Stochastic optimization is an approach that incorporates randomness into the process of searching for optimal solutions in complex problems. Unlike deterministic methods, which follow a predefined…

Mathematics and statistics

Stochastic optimization model

The stochastic optimization model is a mathematical approach that integrates randomness into the optimization process, allowing for the discovery of optimal solutions under conditions of uncertainty…

Artificial intelligence

Stochastic Policy

A stochastic policy in the context of reinforcement learning is an approach that defines a probability distribution over the actions an agent can take in a given state. Unlike a deterministic policy…

Mathematics and statistics

Stochastic Process

A stochastic process is a mathematical model that describes a sequence of events that are probabilistic by nature. Unlike deterministic processes, where the outcome is predictable and fixed…
