De momento los humanos somos más precisos que las máquinas clasificando fotos, pero no por mucho
La gente de Perficient Digital ha publicado un interesante estudio que compara diferentes sistemas de reconocimiento de imágenes: Image Recognition Accuracy Study. Se comparan cuatro sistemas: Amazon AWS Rekognition, Google Vision, IBM Watson y Microsoft Azure Computer Vision, a los que se añade como control y comparación «humanos clasificando a mano». En total se utilizaron unas 500 imágenes para evaluar diversos parámetros.
En cuanto a precisión los humanos todavía estamos por delante, con una precisión del 88% seguidos de Google Vision (hace poco hablamos de su demo), Rekognition de Amazon, y los sistemas de Microsoft e IBM. Curiosamente tres de los cuatro sistemas clasifican con un 90% de confianza más de 5 etiquetas (que es hasta donde llegan los humanos)
La clasificación humana también es muy superior cuando se trata de describir una imagen (la siguiente en la lista es Google Vision). También hay alguna que otra curiosidad, como que Watson de IBM es la que tiene una mayor capacidad para distinguir y nombrar colores (términos como «jade», «azul metálico», «gris ceniza»… frente a «amarillo») y Amazon –apropiadamente– para reconocer términos relacionados con la vestimenta: camisetas, pantalones y ropa interior.

- La demo de la API de Cloud Vision, la IA de aprendizaje automático de Google, resulta un poco inquietante cuando la pruebas con tus fotos
- El reconocimiento facial y de escenas de Amazon en la picota: Rekognition

Which size Instant Pot Aura should you buy?
Best answer: If you can afford it, we'd strongly suggest opting for the larger (and obviously more expensive) Instant Pot Aura Pro. On top of giving you a larger capacity, which is great for cooking for a crowd, it offers more features and better functionality than its little buddy.
- 6-quart: Instant Pot Aura ($60 at Amazon)
- 8 quart: Instant Pot Aura Pro ($180 at Amazon)
Size it up
Two quarts might not seem like a huge difference, but when you're trying to squeeze your over-sized Thanksgiving ham into a 6-quart slow cooker, you'd be really grateful for an 8-quart version. Obviously, that size difference does impact the cookers' footprints on your countertop. The Aura Pro measures a not inconsiderable 16.8 x 11.6 x 11.3 while the other model is a teensy bit more svelte at 16.8 x 11.6 x 10.7. Likewise, the Aura weighs in a tad lighter at 11.7 lbs while the Aura Pro hefts it up with a bulk of 12.9 lbs.
The cooking pots are also different. The Aura offers a non-stick ceramic coated aluminum pan, while the Aura Pro gives you a bi-ply stainless steel interior with an aluminum exterior. Other features worthy of note that are the same for both models are the tempered glass lid (perfect for monitoring your meals without letting out heat), the 24-hour "Delay Start" functionality, and the fact both cooking pots are (hurrah!) dishwasher safe.
So controlling
The Aura Pro beats the 6-quart version with 11 smart built-in cooking programs versus 10. Both models can roast, stew, steam, slow cook, bake, cook rice, make yogurt, sear/saute, and keep food warm. However, the Aura Pro also gets a multigrain cooking program and crucially for some, it can sous vide. This function means you can cook vacuum-packed food in an evenly and accurately controlled water-bath. It's an amazing way to seal in flavors and ensure meat and fish is super tender. So, when it comes to it, you have to consider the size of your family, how often you host, and what you'll be cooking.
Do go Pro
Instant Pot Aura Pro
Eight's great
Aura: $60 at Amazon Aura Pro: $180 at Amazon
The Instant Pot Aura is a cool multicooker currently available for a very good price. But, quite simply, the 8-quart sous vide-capable Aura Pro is clever, bigger and better than the plain old Aura. We would 100% recommend spending that extra money so that you can go Pro.
