Resumen
Este estudio introduce un nuevo marco para la adaptación de dominio sin supervisión (UDA) utilizando modelos de lenguaje visual (VLM). Aborda efectivamente la brecha de modalidad, mejorando el rendimiento y la eficiencia computacional en tareas interdisciplinarias.
Área de la Ciencia:
- Inteligencia artificial
- Visión por computadora
- Procesamiento del lenguaje natural
Sus antecedentes:
- La adaptación de dominio sin supervisión (UDA) tiene como objetivo generalizar los modelos de dominios de origen etiquetados a dominios de destino sin etiquetar.
- Los modelos de lenguaje de visión (VLM) previamente entrenados son prometedores en UDA al alinear las incorporaciones de visión y texto, pero la brecha de modalidad dificulta el rendimiento.
- La UDA directa con VLM a menudo transfiere solo conocimientos invariables en la modalidad, lo que lleva a resultados subóptimos.
Objetivo del estudio:
- Proponer un marco unificado para la AUD que aborde la brecha de modalidad en los MAV.
- Desenredar y manejar por separado los componentes específicos de la modalidad y los invariantes de la modalidad para una mejor adaptación.
- Introducir una métrica de discrepancia de modalidad para la categorización de muestras y la adaptación dirigida.
Principales métodos:
- Se propone un marco unificado de separación de modalidades para desentrañar las características de VLM en componentes invariantes específicos de cada modalidad.
- Los pesos de conjunto adaptativos a la modalidad se determinan en el momento de la prueba para maximizar la sinergia de los componentes.
- Una métrica de discrepancia de modalidad categoriza las muestras, lo que permite el uso específico de muestras invariantes de modalidad para la alineación y muestras inciertas para la anotación.
Principales resultados:
- El marco propuesto consigue un aumento del rendimiento de hasta un 9% en las tareas de la ADU.
- El método demuestra un aumento de 9 veces en la eficiencia computacional en comparación con los enfoques existentes.
- Los experimentos en diversos entornos validan la eficacia y la robustez del marco.
Conclusiones:
- El marco unificado de separación de modalidades cierra efectivamente la brecha de modalidades en los VLM para la AUD.
- El enfoque mejora la generalización entre dominios aprovechando tanto el conocimiento específico de la modalidad como el invariante.
- Este trabajo ofrece una solución computacionalmente eficiente y de alto rendimiento para UDA con VLM.

Language and Cognition
440
Language serves as a bridge between ideas and communication, influencing how individuals perceive and interact with the world. Psychologists have long debated whether language shapes thought or vice versa. This discussion gained grip with Edward Sapir and Benjamin Lee Whorf in the 1940s, who proposed that language determines thought, a concept known as linguistic determinism. They suggested that the vocabulary and structure of a language influence how its speakers think and perceive reality.

Language Development
447
Children master language quickly and with relative ease, supported by both biological predisposition and reinforcement. B. F. Skinner (1957) proposed that language is learned through reinforcement, while Noam Chomsky (1965) argued that language acquisition mechanisms are biologically determined.
The critical period for language acquisition suggests that the ability to acquire language is at its peak early in life. As people age, this proficiency decreases. Language development begins very...

Components of Language
392
Language, whether spoken, signed, or written, consists of specific components: lexicon and grammar. The lexicon is the vocabulary of a language, comprising its words. Grammar is the set of rules used to convey meaning through the lexicon. For example, English grammar adds “-ed” to most verbs to indicate past tense. Words are formed by combining phonemes, which are the basic sound units of a language. Different languages have different sets of phonemes (e.g., “ah” vs.

Visual System

Light enters the eye through the cornea, a transparent, dome-shaped surface covering the surface of the eyeball that helps to direct and focus incoming light. This light is then channeled toward the pupil, an adjustable opening whose size is controlled by the iris. The iris, a pigmented muscle, regulates the amount of light entering the eye by contracting or dilating the pupil, thereby ensuring optimal light levels for clear vision.
Once through the pupil, the light passes through the lens, a...

Vision
55.3K
Vision is the result of light being detected and transduced into neural signals by the retina of the eye. This information is then further analyzed and interpreted by the brain. First, light enters the front of the eye and is focused by the cornea and lens onto the retina—a thin sheet of neural tissue lining the back of the eye. Because of refraction through the convex lens of the eye, images are projected onto the retina upside-down and reversed.

Sensory Modalities

Sensation typically is the process by which the sensory receptors and sense organs detect stimuli from the internal and external environment and transmit this information to the central nervous system for processing.
General senses refer to the broad category of sensory information detected by receptors in the body and can be further grouped into somatic and visceral senses. Somatic sensations include touch, pressure, temperature, and pain and are essential for navigating our environment and...
