- [Narradora] Bienvenidos[br]a Nobel Conversations.

0:00:07.000,0:00:08.521
En este episodio,[br]Josh Angrist y Guido Imbens

0:00:08.521,0:00:09.282
están con Isaiah Andrews[br]para discutir y discrepar

0:00:09.282,0:00:09.662
sobre el papel[br]del aprendizaje automático

0:00:09.662,0:00:10.043
en la econometría aplicada.

0:00:10.043,0:00:11.859
- [Isaiah] Entonces, por supuesto[br]que hay muchos temas

0:00:11.859,0:00:12.767
en los que ustedes están muy de acuerdo,[br]pero me gustaría pasar a uno

0:00:12.767,0:00:13.675
en el que tal vez[br]tengan algunas discrepancias.

0:00:13.675,0:00:15.127
Me gustaría escuchar[br]algunas de sus opiniones

0:00:15.127,0:00:15.853
sobre el aprendizaje automático

0:00:15.853,0:00:16.580
y el papel que está desempeñando[br]y va a desempeñar en la economía.

0:00:17.897,0:00:18.833
- [Guido] He consultado algunos datos[br]como el propietario----------------------.

0:00:18.833,0:00:19.301
Vemos que no hay[br]ningún documento publicado allí.

0:00:19.301,0:00:19.535
Se hizo un experimento[br]sobre algún algoritmo de búsqueda

0:00:19.535,0:00:19.652
y la cuestión era...

0:00:19.652,0:00:19.710
se trataba de clasificar cosas[br]y cambiar la clasificación.

0:00:19.710,0:00:19.739
Y estaba más o menos claro[br]que iba a haber mucha heterogeneidad.

0:00:19.739,0:00:19.754
Si buscas, digamos, una foto de Britney Spears --

0:00:19.754,0:00:19.761
realmente no importa dónde la clasifiques-----------------------------------[br]porque vas a encontrar lo que estás buscando,

0:00:19.761,0:00:19.765
ya sea que la pongas en la primera,[br]segunda o tercera posición del ranking.

0:00:19.765,0:00:19.767
Pero si estás buscando[br]el mejor libro de econometría,

0:00:19.767,0:00:19.768
si pones tu libro en primer lugar[br]o en el décimo,

0:00:19.768,0:00:19.768
eso va a suponer una gran diferencia

0:00:19.768,0:00:19.768
en la frecuencia[br]con la que la gente va a hacer clic en él.

0:00:19.768,0:00:19.769
Así que ahí...
