Todos hablan de los algoritmos, pero pocos saben lo que son

Lo que leemos al abrir Facebook depende de un algoritmo; también, la ruta que traza Waze para llegar en el menor tiempo posible a un punto y Amazon al sugerir productos con base en clics y compras anteriores.

Estamos en un mundo donde muchas de las acciones cotidianas dependen de un algoritmo, un concepto que se ha vuelto imprescindible, del que todos hablan pero que muy pocos entienden.

“La definición más simple de algoritmo es que es una secuencia de reglas que toman datos de entradas y los transforman en datos de salidas”, dice Jorge Pérez, investigador del Instituto Milenio de los Fundamentos de los Datos y académico de la Universidad de Chile. Un ejemplo de la vida cotidiana es una receta de cocina. A partir de ciertos elementos (los ingredientes), se realiza un procedimiento (la preparación) que da un resultado (una torta de limón). En este caso, el conjunto de instrucciones es un algoritmo.

“Los algoritmos se diseñan para resolver problemas. Optimizar tu trayecto al dejar a tu hijo y tu señora en las mañanas es un algoritmo que vas mejorando con el tiempo. Lo que hay que tener claro es que para un mismo problema puede haber varias soluciones, unas mejores que las otras y que son probadas en la realidad. Y eso pasa constantemente con los algoritmos”, dice Jorge Pavez, jefe de Innovación y Desarrollo de la Universidad Mayor.

El tema se ha vuelto candente con la inteligencia artificial y el aprendizaje de máquinas. “Pero hay que tener claro que los algoritmos no piensan, solo se ejecutan para que sigan las instrucciones. Turing, el padre de la computación, ya decía que no tenía lógica hablar de máquinas inteligentes, sino de máquinas que emulan el actuar de seres inteligentes”, dice Pérez.

Jóvenes disminuyen el uso de Facebook en Estados Unidos

Actualmente la red social más utilizada en ese país es YouTube, seguida de Snapchat e Instagram.

Facebook pierde popularidad entre los jóvenes de Estados Unidos, pues de acuerdo con un estudio realizado por Pew Research Center, el 51 por ciento de los adolescentes entre 13 y 17 años usa esa plataforma. Dicha cifra refleja un decremento, teniendo en cuenta que hace tres años esa interacción se situaba en el 71 por ciento. De acuerdo con el análisis, actualmente la red social más utilizada entre los jóvenes de ese país es YouTube, luego aparece Snapchat y por último está Instagram.

“Hoy, el entorno de los medios sociales gira menos que hace tres años alrededor de una sola plataforma”, escribieron los autores de la investigación. YouTube, de Google, es la plataforma más popular, ya que es utilizada por el 85 por ciento de los adolescentes.

Estados Unidos es de lejos el mercado publicitario más lucrativo de Facebook, donde recibe la impresionante suma de 23,59 dólares de ingresos trimestrales por usuario. Pero eso no significa que el crecimiento pueda continuar para siempre. La compañía dijo que en la práctica ha saturado el mercado en EE. UU. y Canadá, pues tiene 185 millones de usuarios entre ambos países. El estudio demuestra lo difícil que puede ser mantener ese nivel de dominio y lo importante que ha sido para el futuro de Facebook la adquisición de Instagram en 2012.

Instagram es levemente más popular que Snapchat, explicó Pew, ya que el 72 por ciento de los encuestados afirmó usar la aplicación para compartir fotos, frente a un 69 por ciento para Snapchat. Alrededor de un tercio de los encuestados indicó visitar Snapchat y YouTube con más frecuencia, mientras que el 15 por ciento señaló que Instagram es su destino más frecuente.

Entretanto, solo el 10 por ciento de los adolescentes dijo que Facebook es su plataforma en línea más usada.

La investigación de Pew se basó en una encuesta a 1.058 padres que tienen un hijo adolescente entre 13 y 17 años, así como en entrevistas a 743 adolescentes. Estas últimas se realizaron en línea y por teléfono desde el 7 de marzo hasta el 10 de abril.

El centro de investigaciones aseguró también que el cambio más grande desde su última encuesta a adolescentes, además del hecho de que Facebook dejara de tener el dominio digital, es la masificación de los teléfonos inteligentes entre los jóvenes estadounidenses. De acuerdo con el análisis, el 95 por ciento de los adolescentes posee un teléfono inteligente o tiene acceso a uno.

¿Usted pagaría una suscripción para usar Facebook?

Facebook podría establecer un servicio sin publicidad basado en suscripciones

Facebook Inc. ha estado realizando una investigación de mercado en las últimas semanas para determinar si una versión sin publicidad pagada por suscripciones incentivaría a más personas a unirse a la red social, de acuerdo con personas con conocimiento del tema.

La compañía había estudiado una opción de este tipo antes, pero ahora hay un mayor impulso interno para evaluarlo a la luz del reciente escándalo de datos privados de Facebook, dijeron las personas.

Los planes no son concretos y podrían no prosperar, de acuerdo con las personas, que pidieron no ser identificadas, dado que las conversaciones son privadas. Facebook declinó comentar sobre la posibilidad de un servicio sin publicidad basado en suscripciones.

El máximo ejecutivo de la empresa, Mark Zuckerberg, y la directora de operaciones, Sheryl Sandberg, pasaron gran parte de la teleconferencia sobre los resultados del primer trimestre de Facebook pregonando los beneficios de la red financiada por publicidad, que, según dijeron, permite a la compañía llegar a la mayor cantidad de personas, en todos los niveles de ingresos.

Pero no es la única forma de dirigir el negocio. “Sin duda pensamos en muchas otras formas de monetización, incluidas las suscripciones, y siempre seguiremos evaluando todo”, dijo entonces Sandberg.

Durante su testimonio ante el Congreso el mes pasado, Zuckerberg dejó la puerta abierta a una opción de suscripciones. “Siempre habrá una versión de Facebook gratuita”, dijo.

Zuckerberg ha analizado durante mucho tiempo ese tipo de alternativa; no para reemplazar el modelo de negocios de la red social, sino para eliminar una razón común que las personas dan para abandonar el servicio.

La compañía generó prácticamente la totalidad de sus US$41.000 millones en ingresos el año pasado mediante la venta de publicidad orientada con datos de usuarios.

Investigaciones internas de la compañía en años anteriores concluyeron que los consumidores no estarían muy abiertos a una opción de suscripción, ya que considerarían codicioso de parte de Facebook pedir dinero por algo que decía que siempre seria gratis, dijeron las personas.

Ahora, Facebook piensa que la percepción de los consumidores puede estar cambiando. La compañía enfrenta una crisis de confianza pública luego de que un desarrollador proporcionara información personal de millones de usuarios de Facebook a Cambridge Analytica, una consultora política que trabajo en la campaña presidencial de Donald Trump en 2016.

La noticia sobre la filtración de datos generó interrogantes sobre la información que Facebook recopila de las personas para publicidad, y sobre si los usuarios son rastreados y son objeto de publicidad de maneras que no esperan ni entienden.

La compañía con sede en Menlo Park, California, ha llevado a cabo una amplia revisión de su negocio para identificar formas de llenar posibles vacíos de seguridad y, de forma más general, recuperar la confianza de los usuarios y mejorar su experiencia.

La empresa ha sido receptiva a cambios que incluso hace un año hubieran sido impensables, como clasificar a los editores de noticias por su confiabilidad y permitir la votación positiva y negativa de los comentarios. Los ejecutivos también se han enfrentado a preguntas difíciles por parte de los empleados, como si Facebook debería ofrecer publicidad política.

Sandberg dijo a Bloomberg News el mes pasado que la red social debería seguir aceptando avisos políticos para promover la libertad de expresión.

A Simple Guide to Bulk Editing in WordPress

I’m designing a document and don’t want to get bogged down in what the text actually says. Visual context supposes the use of imagery, color, space, and other attributes that will reflect the pur pose of the website. For instance, if you enter a website devoted to spa and beauty, it is obvious to see the hot stones, andles, towels, flowers, bottles with cosmetics, and other photos in the slider or in the header of the homepage. Some other icons and symbols on the web page should also reflect its main subject to make a visitor understand it within a few seconds.

When you create a visual context, it’s important to learn the interests of your audience and its main peculiarities. That means you should know the age, nationality, gender, and some other characteristics to understand the needs of your community and your main users.

  1. Photos related to the website’s purpose
  2. Storytelling through graphics elements
  3. Appealing icons
  4. Slogans, words and phrases
  5. Infographics
  6. Visual perception
