Understanding State-Action-Reward-State-Action: Definition, Explanations, Examples & Code
SARSA (State-Action-Reward-State-Action) is a temporal difference on-policy algorithm used in reinforcement learning to train a Markov decision process model on a new policy. This algorithm falls under the category of reinforcement learning, which focuses on how an agent should take actions in an environment to maximize a cumulative reward signal.

What is a State-Aware Tracker and Why is it Important?
If you've ever watched a video of a moving object, you may have noticed that it can be difficult to keep track of the object as it moves around the screen. This is where a State-Aware Tracker comes in. A State-Aware Tracker is a pipeline that can help identify and track objects in a video sequence.
Not only is this useful for monitoring moving objects, but it can also be used for things like video editing, virtual reality, and robotics. In
Stein Variational Policy Gradient (SVPG) Overview
Stein Variational Policy Gradient (SVPG) is a policy gradient-based method used in reinforcement learning to simultaneously exploit and explore multiple policies. Instead of learning a single policy, SVPG models a distribution of policy parameters.
Traditional Policy Optimization vs. SVPG
Traditional policy optimization uses a single policy for decision-making. It works by evaluating the reward or utility of different actions and then selecti

Stereo-LiDAR Fusion: A Powerful Tool for Depth Estimation
Depth estimation is a critical function in many artificial intelligence applications, including self-driving cars, robotics, and virtual reality. Stereo cameras and LiDAR sensors are some of the most commonly used technologies for depth estimation. However, each technology has its limitations, such as stereo cameras having difficulties with low light conditions or LiDAR sensors struggling in highly reflective environments.

When you're having a conversation, sometimes words just aren't enough to express how you're feeling. That's where stickers come in - those little pictures that you can send in chat apps. But what if there was a way for a computer to choose the perfect sticker for you, based on what you're saying and the context of the conversation? That's where Sticker Response Selector (SRS) comes in.
What is SRS?
SRS stands for Sticker Response Selector. It's a way for computers to automatically choose a st
Stochastic Depth is a technique used to reduce the depth of a network during training, while keeping it the same during testing. This is accomplished by randomly dropping entire ResBlocks during training and bypassing their transformations through skip connections.
What is Stochastic Depth?
Stochastic Depth is a method used in deep learning to reduce the depth of a neural network during training. By randomly dropping ResBlocks (a type of structure in a neural network) during training, the net
What is a Stochastic Dueling Network?
A Stochastic Dueling Network, or SDN, is a type of machine learning architecture used to learn a value function called V. Essentially, it is a way for a computer program to estimate the value of possible actions in a given situation.
The way an SDN works is that it uses two models that work together: a stochastic model and a deterministic model. The deterministic model estimates the value of each possible action, while the stochastic model estimates the pr
Stochastic Gradient Descent (SGD): A Simple Overview
Machine learning models are essential in predicting outcomes, identifying trends, and giving insights from data. We use mathematical techniques like optimization to train models, making them more accurate in making predictions for future data. One popular optimization technique is stochastic gradient descent (SGD).

SGD is an iterative optimization technique that uses mini-batches of data to calculate the gradient of the loss f
Stochastic Human Motion Prediction: Predicting Multiple Possible Futures
Stochastic Human Motion Prediction is a method of predicting the future movement of a human or a group of humans. The key difference between traditional prediction techniques and stochastic prediction is that stochastic prediction assumes future randomness and provides multiple possible outcomes instead of a single outcome. This approach allows for a more accurate and flexible representation of human motion in various scen
Introduction to Stochastic Optimization
Stochastic Optimization is a method of optimizing objective functions using randomly generated variables. This iterative process finds the minimum or maximum value of the objective function through trial and error. Stochastic Optimization is used in non-convex functional spaces where deterministic optimization methods, such as linear or quadratic programming, are not feasible.

SSE, which stands for Stochastic Steady-state Embedding, is an algorithm used to learn steady-state algorithms on graphs. Unlike other graph neural network models, SSE is stochastic and only requires 1-hop information to efficiently and effectively capture fixed point relationships.
How does SSE work?
SSE works by taking in a graph and a given steady-state algorithm. It then uses stochastic gradient descent to learn the parameters of the algorithm through backpropagation. SSE us
Stochastic Weight Averaging (SWA) is an optimization procedure used in machine learning that involves averaging multiple points along the trajectory of stochastic gradient descent (SGD). It involves averaging weights and using a cyclical or constant learning rate to discover broader optima.

SSFG regularization is a method of data analysis that is used to solve a common problem in machine learning. This problem is called overfitting, and it occurs when a model is too complex, and it starts to fit the noise in the training data instead of the underlying pattern.
Overfitting can lead to poor performance when the model is used on new data, and it is a significant problem in machine learning. To solve this problem, SSFG regularization is used to reduce the
