  • This simple change made Google's ad marketplace much more efficient than Overture's. Notice that the algorithm itself is quite simple; it is the addition of the new data that made the difference.
  • Of course, you have to be judicious in your choice of the data to add to your data set.

    But the bigger point is, adding more, independent data usually beats out designing ever-better algorithms to analyze an existing data set. I'm often suprised that many people in the business, and even in academia, don't realize this.

    According to Eva Tardos, Jacob Gould Schurman Professor of Computer Science at Cornell University, the researchers' paper "is more the beginning of research than a definitive result or end product." The researchers' models make several simplifying assumptions - including the number of competitors - that make the math easier but limit their applicability. Nonetheless, "just raising the questions is an important step forward," Tardos says.

  • we’re going to experiment with running the course without an LMS and using only gRSShopper for interaction

      excellent idea
  • Curation is an important component in the process.
  • Curation is important – yes, it’s biased, yes it misses contributions, but it’s personal
  • ...9 more annotations...
  • I think we need to also focus on the human aspect of data, sensemaking, curation, and trust.

      programa que soluciones esto?
  • la falta de archivos y la integración de las conversaciones en otros espacios en el correo electrónico diario. Hay dos razones principales para ello: Queremos demostrar que si alguien quiere ofrecer un curso en línea abierta, que no es necesario para ejecutar su propio servidor o escribir su propio software. Nosotros no pedimos Stephen si podría funcionar este curso en su sitio
  • Lo que perder - y todavía estoy inquieto acerca de esta compensación - es el archivo integrada de la actividad en el curso. Puedo enviar un correo electrónico diario al grupo de Google. Yo enlaces agregados / deliciosa / diigo / enlaces Twitter y comentarios sobre mi página de Netvibes . El problema, sin embargo, es que Netvibes es más bien tonto. Simplemente deja el contenido de la página hasta que algo nuevo ha sido publicado. Si usted es el seguimiento de la actividad en Netvibes, es probable que gran parte del encuentro el mismo contenido hasta que se ha actualizado con nuevo contenido. La actividad no se archivan por fecha.
  • Para CCK11 (a partir del lunes), vamos a experimentar con la realización del curso sin un LMS y el uso de gRSShopper sólo para la interacción. En LAK11, una de las adiciones clave parece ser el papel de "Defensor curso" que Dave Cormier está cumpliendo.
  • Tony Searl está empezando a desempeñar un papel similar al agregar los blogs del curso y contenido en función de sus intereses.
  • Curación es un componente importante en el proceso.
  • Si bien la información está creciendo en la abundancia y las herramientas y algoritmos (minería de datos, visualización) se están desarrollando como soluciones, no podemos pasar por alto la importancia de la señalización y la construcción de sentido en los sistemas sociales

    Social and technological networks don't have a centre. When we learn in a classroom or in a learning management system (LMS), a central place exists where we can go for readings and

      why?
  • thanks to various Hadoop optimizations, complementary technologies and advanced algorithms, real-time analytics are becoming a real possibility
  • react promptly to sensor readings or analyze web logs as they are generated because that type of information becomes quickly obsolete.
  • ...2 more annotations...
  • But the most interesting thing about it might be that it was hardly even possible a few years ago
  • the evolution from batch processing to real-time processing has happened quickly.

    Among the greatest innovations might be the advent of real-time analytics, which allow the processing of information in real time to enable instantaneous decision-making.
