Sistemas difusos (Coursera)

Offered by Universidad Nacional de Colombia,

Los sistemas difusos permiten efectuar cálculos cuando hay información con incertidumbre, o cuando se debe combinar información tanto cuantitativa como cualitativa. Se trata de una aproximación matemática para modelar esas situaciones. Este curso está diseñado para ayudar a entender y explicar cómo funcionan dichos sistemas. El curso tiene una aproximación teórica y práctica. Los principios matemáticos son de un nivel bajo y están al alcance de un público muy amplio. El curso cuenta con varios laboratorios para aprender a utilizar las herramientas de software que usan esos principios. Este componente práctico requiere una comprensión mínima de programación.

Syllabus

WEEK 1
Teoría de conjuntos difusos
En esta semana se presentan los principios básicos de la teoría de conjuntos difusos y sus operaciones. También se explica cómo pueden usarse para ayudar a representar algunas situaciones en las que la información es imperfecta.
Recuerde que también puede consultar el ítem recursos durante todo el curso, allí puede encontrar información de utilidad.

WEEK 2
Lógica difusa y razonamiento aproximado
En esta semana se presentan los sistemas difusos más conocidos. Se denominan 'Sistemas Basados en Reglas', o también 'Controladores Difusos'. Estos sistemas implementan una forma de razonamiento aproximado que se basa en la lógica difusa. En esta semana se muestran también varias herramientas de software.

WEEK 3
Aprendizaje de máquina
En esta semana se muestran algunos ejemplos sobre cómo se pueden usar las estrategias de aprendizaje de máquina para diseñar u optimizar los sistemas basados en reglas, o algunos de sus componentes.

WEEK 4
Aritmética difusa
En esta semana se presentan los ''Sistemas de Computación con Palabras basados en Aritmética Difusa'. Con este tipo de sistemas se pueden modelar situaciones complejas, de un elevado número de variables, sin incurrir en el problema de explosión de la base de reglas.

Sample-based Learning Methods (Coursera)

Data Science

In this course, you will learn about several algorithms that can learn near optimal policies based on trial and error interaction with the environment---learning from the agent’s own experience. Learning from actual experience is striking because it requires no prior knowledge of the environment’s dynamics, yet can still attain optimal behavior. We will cover intuitively simple but powerful Monte Carlo methods, and temporal difference learning methods including Q-learning. We will wrap up this course investigating how we can get the best of both worlds: algorithms that can combine model-based planning (similar to dynamic programming) and temporal difference updates to radically accelerate learning.

Management & Leadership Statistics & Data Analysis

Have you ever had the perfect data science experience? The data pull went perfectly. There were no merging errors or missing data. Hypotheses were clearly defined prior to analyses. Randomization was performed for the treatment of interest. The analytic plan was outlined prior to analysis and followed exactly. The conclusions were clear and actionable decisions were obvious. Has that every happened to you? Of course not. Data analysis in real life is messy. How does one manage a team facing real data analyses? In this one-week course, we contrast the ideal with what happens in real life. By contrasting the ideal, you will learn key concepts that will help you manage real life analyses.
