Embeddings de Distribución Generativa: Elevando los autoencoders al espacio de distribuciones para el aprendizaje de
ArXiv
|February 27, 2026
Resumen
Los Embeddings de Distribución Generativa (GDEs) representan distribuciones de datos completas, no solo puntos individuales. Este marco destaca en tareas de biología computacional, ofreciendo nuevas y potentes herramientas para el análisis de datos biológicos complejos.
Área de la Ciencia:
- Aprendizaje Automático
- Biología Computacional
- Modelos Generativos
Sus antecedentes:
- Muchos desafíos científicos requieren el análisis de distribuciones de datos completas, no puntos de datos aislados.
- Los modelos existentes a menudo luchan con el razonamiento multiescala en conjuntos de datos complejos.
- Existe la necesidad de marcos avanzados capaces de aprender y representar distribuciones.
Objetivo del estudio:
- Introducir los Embeddings de Distribución Generativa (GDEs), un marco novedoso para extender los autoencoders al espacio de distribuciones de datos.
- Permitir el aprendizaje de representaciones distribucionales robustas utilizando modelos generativos condicionales e invarianza distribucional.
- Demostrar la eficacia de los GDEs en la captura de propiedades estadísticas esenciales y la habilitación de operaciones significativas en el espacio latente.
Principales métodos:
- Desarrollamos un marco (GDEs) donde los codificadores procesan conjuntos de muestras y los decodificadores son reemplazados por generadores que igualan las distribuciones de entrada.
- Incorporamos modelos generativos condicionales con redes codificadoras que satisfacen la invarianza distribucional.
- Utilizamos embeddings del espacio de Wasserstein para aprender estadísticas suficientes predictivas.
Principales resultados:
- Los GDEs aprenden representaciones latentes donde las distancias aproximan la distancia de Wasserstein ($W_2$) y las interpolaciones recuperan trayectorias de transporte óptimo para distribuciones gaussianas.
- La evaluación sistemática en conjuntos de datos sintéticos muestra un rendimiento superior en comparación con los métodos existentes.
- Aplicamos con éxito los GDEs a seis problemas diversos de biología computacional, incluida la genómica de células únicas, la transcriptómica y el análisis de secuencias de proteínas.
Conclusiones:
- Los GDEs proporcionan un método potente para aprender y representar distribuciones de probabilidad, superando a los enfoques existentes.
- El marco demuestra un potencial significativo para avanzar en la biología computacional al permitir el análisis de datos biológicos complejos a gran escala.
- Los GDEs ofrecen una herramienta versátil para diversos dominios científicos que requieren razonamiento distribucional.

Scaling
621
In designing and analyzing filters, resonant circuits, or circuit analysis at large, working with standard element values like 1 ohm, 1 henry, or 1 farad can be convenient before scaling these values to more realistic figures. This approach is widely utilized by not employing realistic element values in numerous examples and problems; it simplifies mastering circuit analysis through convenient component values. The complexity of calculations is thereby reduced, with the understanding that...

Multi-input and Multi-variable systems
441
Cruise control systems in cars are designed as multi-input systems to maintain a driver's desired speed while compensating for external disturbances such as changes in terrain. The block diagram for a cruise control system typically includes two main inputs: the desired speed set by the driver and any external disturbances, such as the incline of the road. By adjusting the engine throttle, the system maintains the vehicle's speed as close to the desired value as possible.

Transformers in Distribution System

Transformers in distribution systems can be broadly categorized into distribution substation transformers and other distribution transformers. They are crucial for stepping down high transmission voltages to levels suitable for distribution and end-user applications.
Distribution substation transformers come in various ratings and typically use mineral oil for insulation and cooling. To prevent moisture and air from entering the oil, some transformers use an inert gas like nitrogen to fill the...

Sequence Networks of Rotating Machines
510
A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Upsampling
670
Managing signal sampling rates is essential in digital signal processing to maintain signal integrity. A decimated signal, characterized by a reduced frequency range due to its lower sampling rate, can be upsampled by inserting zeros between each sample. This upsampling process expands the original spectrum and introduces repeated spectral replicas at intervals dictated by the new Nyquist frequency. To refine this zero-inserted sequence, it is passed through a lowpass filter with a cutoff...

Multicompartment Models: Overview
660
Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...
