Understanding Deception01:14

Understanding Deception

142
Deception is a pervasive aspect of human communication. Empirical studies have shown that most individuals engage in some form of deceit on a daily basis, with approximately 20% of social exchanges involving deceptive elements. Lying follows a developmental trajectory, peaking during adolescence and declining with age, possibly due to the maturation of cognitive control and social accountability.Cognitive and Social Factors in Deception DetectionDespite its prevalence, accurately detecting...

Graphical Representation of Inequalities01:28

Graphical Representation of Inequalities

150
The graph of the equation where y equals x squared forms a curve known as a parabola. This curve acts as a boundary in the coordinate plane, dividing it into distinct regions based on the relative position of points.When the equality sign in the equation is replaced with an inequality—such as greater than, less than, greater than or equal to, or less than or equal to—the graphical representation changes from a single curve into a broader shaded area that signifies the set of all...

Difference from Background: Limit of Detection01:05

Difference from Background: Limit of Detection

8.0K
The limit of detection (LOD) is the smallest amount of analyte that can be distinguished from the background noise. The LOD value corresponds to the concentration at which the analyte signal is three times larger than the standard deviation of the blank signal. Below this value, the analyte signal cannot be differentiated from the background noise. It is calculated by dividing the calibration slope by 3 times the standard deviation of the blank signals.
The LOD indicates the presence or absence...

Detection of Gross Error: The Q Test

6.8K
When one or more data points appear far from the rest of the data, there is a need to determine whether they are outliers and whether they should be eliminated from the data set to ensure an accurate representation of the measured value. In many cases, outliers arise from gross errors (or human errors) and do not accurately reflect the underlying phenomenon. In some cases, however, these apparent outliers reflect true phenomenological differences. In these cases, we can use statistical methods...

Aggregates Classification01:29

Aggregates Classification

950
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...

Quantifying and Rejecting Outliers: The Grubbs Test01:02

Quantifying and Rejecting Outliers: The Grubbs Test

3.4K
Sometimes, a data set can have a recorded numerical observation that greatly  deviates from the rest of the data. Assuming that the data is normally distributed, a statistical method called the Grubbs test can be used to determine whether the observation is truly an outlier.  To perform a two-tailed Grubbs test, first, calculate the absolute difference between the outlier and the mean. Then, calculate the ratio between this difference and the standard deviation of the sample. This...

Área de la Ciencia:

  • Inteligencia Artificial
  • Aprendizaje Automático
  • Ciberseguridad

Sus antecedentes:

  • Las plataformas digitales se enfrentan a fraudes sofisticados que utilizan ataques de múltiples saltos.
  • Las Redes Neuronales de Grafos (GNN) tradicionales tienen dificultades con patrones de fraude complejos debido a la homofilia, el desequilibrio de etiquetas y el ruido.
  • Los métodos existentes no logran capturar las estructuras relacionales de orden superior en las redes de fraude.

Objetivo del estudio:

  • Desarrollar un marco novedoso, la Red de Aprendizaje Contrastivo Basada en Hipergrafos (HCLNet), para la detección de fraudes camuflados.
  • Superar las limitaciones de las GNN tradicionales para capturar patrones de fraude complejos y de orden superior.
  • Mejorar la precisión y robustez de los sistemas de detección de fraudes en los ecosistemas digitales.

Principales métodos:

  • Fusión de hipergrafos multirrelacionales para modelar sindicatos de fraude grupales.
  • Agregación de hipergrafos con compuertas multienabezales para la captura de patrones diversos y el equilibrio de características.
  • Aprendizaje contrastivo jerárquico de doble vista con enmascaramiento de características y abandono de topología para la discriminación autocontenida.

Principales resultados:

  • HCLNet demostró un rendimiento superior en conjuntos de datos del mundo real en comparación con los métodos de referencia.
  • Se observaron mejoras significativas en las métricas clave de evaluación para la detección de fraudes.
  • El modelo reveló eficazmente patrones de separación distintos entre entidades fraudulentas y benignas

Conclusiones:

  • HCLNet ofrece un nuevo y potente enfoque para combatir las tácticas de fraude camuflado en evolución.
  • La capacidad del marco para modelar relaciones complejas mejora las capacidades de detección.
  • Esta investigación contribuye a una detección de fraudes más robusta en entornos digitales.
