Survival Tree

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Types of Collisions - II

Types of Collisions - II

When two or more objects collide with each other, they can stick together to form one single composite object (after collision). The total mass of the object after the collision is the sum of the masses of the original objects, and it moves with a velocity dictated by the conservation of momentum. Although the system's total momentum remains constant, the kinetic energy decreases, and thus such a collision is an inelastic collision. Most of the collisions between objects in daily life are...

Background:

Traffic accidents pose significant risks in urban environments, necessitating rapid recognition and warning systems.
A major challenge in developing these systems is the scarcity and difficulty of collecting real-world traffic accident data.

Purpose of the Study:

To develop a novel data generation model using Generative Adversarial Networks (GAN) to overcome traffic accident data limitations.
To adapt GANs for non-graphical data and enhance traffic accident recognition model performance.

Main Methods:

A modified Generative Adversarial Network (GAN) with an improved generator network structure was developed for non-graphical data.
The GAN model was used to resample existing traffic accident data, generating a large dataset of synthetic samples.
Statistical tests confirmed the generated data is not significantly different from the original data.

Main Results:

The generated traffic accident data significantly improved the performance of various traffic accident recognition classifiers.
Accuracy in accident recognition increased by up to 3.05%.
The false positive rate in accident recognition decreased by up to 2.95%.

Conclusions:

The proposed GAN-based data generation method provides a reliable solution for creating large-scale traffic accident datasets.
This approach offers crucial data support for enhancing traffic accident recognition and improving overall road traffic safety.
