Deep Learning for Sales Professionals

417 vues

Publié le

AI is considered the biggest commercial opportunity in the changing economy. It is expected to generate $15.7T by 2030 (according to PwC). In this talk I explained what are some of the top business opportunities for cloud sales professionals in the field of deep learning and artificial intelligence. I addressed the most important principles of deep learning techniques and finally, I studied two deep learning problems (image recognition with CNNs and sentiment analysis with RNNs) with 5 different deep learning frameworks.
