bioRxiv : the preprint server for biology
|February 12, 2026
Resumen
MultiGEOmics integra datos multi-ómicos modelando señales regulatorias inter-ómicas, mejorando el aprendizaje automático para la biología y la medicina. Este marco mantiene un rendimiento robusto incluso con datos faltantes, ayudando al análisis de procesos celulares complejos.
Área de la Ciencia:
- Biología Computacional
- Bioinformática
- Aprendizaje Automático en Medicina
Sus antecedentes:
- Los conjuntos de datos multi-ómicos ofrecen una visión biológica completa, pero son difíciles de integrar.
- Los métodos actuales basados en grafos a menudo ignoran las señales regulatorias inter-ómicas cruciales y tienen dificultades con los datos faltantes.
- Los enfoques existentes a menudo no logran modelar eficazmente las interdependencias entre las diferentes capas ómicas.
Objetivo del estudio:
- Introducir MultiGEOmics, un marco novedoso de integración de grafos para datos multi-ómicos.
- Modelar explícitamente las señales y dependencias regulatorias inter-ómicas para una mejor comprensión biológica.
- Desarrollar un método robusto a la falta de datos ómicos para aplicaciones de aprendizaje automático fiables.
Principales métodos:
- Desarrollado MultiGEOmics, un marco de integración de grafos de nivel intermedio.
- Incorporadas señales regulatorias inter-ómicas explícitas en el aprendizaje de la representación de grafos.
- Modeladas dependencias tanto específicas de ómicas como inter-ómicas utilizando enfoques inspirados biológicamente.
Principales resultados:
- MultiGEOmics aprende incrustaciones inter-ómicas robustas, funcionando bien incluso con datos parcialmente faltantes.
- Evaluado en once conjuntos de datos de cáncer y enfermedad de Alzheimer, mostrando un rendimiento predictivo consistentemente fuerte bajo varios escenarios de datos faltantes.
- Demostró interpretabilidad al identificar tipos de ómicas y características clave que impulsan las predicciones.
Conclusiones:
- MultiGEOmics integra eficazmente datos multi-ómicos, superando las limitaciones de los métodos existentes.
- El marco proporciona predicciones fiables e interpretables, incluso con conjuntos de datos incompletos.
- Permite aplicaciones avanzadas de aprendizaje automático en biología y medicina aprovechando la información ómica integrada.

Signal Flow Graphs
667
Signal-flow graphs offer a streamlined and intuitive approach to representing control systems, providing an alternative to traditional block diagrams. These graphs use branches to symbolize systems and nodes to represent signals, effectively illustrating the relationships and interactions within the system.
In a signal-flow graph, branches denote the system's transfer functions, while nodes represent the signals. The direction of signal flow is indicated by arrows, with the corresponding...

Applications of Integration to Find Blood Flow
60
Blood flow through a cylindrical blood vessel can be mathematically described using the principles of laminar flow, a regime in which fluid moves smoothly in parallel layers. In this model, the velocity of the blood is not uniform across the cross-section of the vessel; rather, it varies with the radial distance from the center. The maximum velocity occurs along the central axis, decreasing progressively toward the vessel walls, where it reaches zero due to viscous drag.Approximating Blood...

Introduction to Biological Bases of Psychology
4.7K
Biopsychology serves as a vital bridge connecting the intricate domains of biology and psychology, shedding light on how biological systems influence psychological phenomena. This field scrutinizes the biological substrates of behavior and mental processes, emphasizing the nervous system along with the roles of neurotransmitters, hormones, and genetics. It also incorporates evolutionary perspectives to explain the adaptive nature of mental functions.

Ogive Graph
6.9K
An ogive graph is sometimes called a cumulative frequency polygon. It is one type of frequency polygon that shows cumulative frequency. In other words, the cumulative percentages are added to the graph from left to right. An ogive graph plots cumulative frequency on the vertical y-axis and class boundaries along the horizontal x-axis. It’s very similar to a histogram; only instead of rectangles, an ogive displays a single point where the top right of the rectangle would be. Creating this...

Graphing Antiderivatives
77
The concept of an antiderivative is fundamental in calculus, describing how a function's values accumulate over time. This process is closely related to physical motion, such as the movement of a rolling ball. As the ball progresses, its position changes in response to variations in velocity, just as an antiderivative graph reflects the cumulative effect of the original function's values.Graphing an antiderivative requires interpreting how a function's values influence the shape of its...

Graphs of Functions
360
Graphs of functions provide a visual representation of how output values change in response to varying inputs. Each point on the graph corresponds to an ordered pair, where the x-coordinate (independent variable) determines the horizontal position and the y-coordinate (dependent variable) determines the vertical position. Linear functions like y = x give a straight line, indicating a constant rate of change.Nonlinear functions display more complex behaviors. Even power functions generate...
