"Percepción y recompensa: hacia una IA sustentable" | Sergio Lew | TEDxBarrioSanNicolasSalon
TEDx Talks· 2025-11-20 17:34
Artificial Intelligence Efficiency & Brain-Inspired Computing - Artificial intelligence currently consumes 20,000 W of power, while the human brain only consumes 20 W for similar operations, highlighting the inefficiency of current AI systems [1] - The industry is studying the brain to transfer its mechanisms to artificial intelligence, using a scientific method of hypothesis testing based on animal behavior [2] - Engineers use differential equations and neuronal models to study emergent properties, which are then tested in animals to refine the models [3][4] Reward Systems & Learning in AI - Current artificial intelligence lacks a reward system, which is present even in phylogenetically distant species through dopamine receptors [5] - Dopamine release in the ventral tegmental area reinforces connections between stimuli and predicted rewards, accelerating learning and increasing the signal-to-noise ratio [8][9][10] - Experiments with rats showed that neuronal activity in the frontal cortex anticipates rewards as dopamine release intensifies, improving aspects of neural network learning [11][12] Perception & Consciousness Studies - Perception is subjective and crucial for survival, guiding behavior towards rewards or away from threats [13][14] - Studies on epileptic patients with implanted electrodes allow for in-vivo study of the human brain and consciousness during seizures [15] - Measuring integrated information in the brain correlates with consciousness scores measured by doctors during epileptic seizures [18]
El poder de la observación | Jorge Serrano | TEDxBarrio El Prado

Core Concept - Observation, not just seeing, is a fundamental action that leads to recognition and understanding [4] - Observation enriches the brain by providing new information, making it more analytical, connective, alert, and resourceful [5][6][7][18] - The practice of observation is not limited to artists but is beneficial for everyone, enhancing cognitive abilities [9][16] Observation Methodology - Distinguishes between peripheral vision (fleeting, without detail) and central vision (focused, detailed) [13] - Central vision, like a camera, requires time to focus on a point to reveal details and textures [14][15] - Regular practice of observation, even for a short duration, can lead to significant changes in the brain [9] Benefits of Enhanced Observation - Improved problem-solving, decision-making, and overall cognitive function due to increased information processing [18] - A deeper understanding of reality and the ability to perceive nuances and contradictions [8] - Enriched life experiences and personal growth through continuous learning and adaptation [22][23]
