#Artificial Intelligence Artificial Intelligence and AI has come into the view of the general public, we can see a lot of AI-related products in our life. For example, Siri, AI photo shooting, AI retouching... This article will be a complete answer to your questions. The content of the article will allow non-technical friends can also easily understand. AI's dependence on data is equivalent to human dependence on air Currently (as of 2019) is the most popular era of deep learning, deep learning in various fields, although it has demonstrated a very powerful ability, but not everyone can play deep learning, because it requires a huge amount of data with annotations, this condition is not available to everyone. Simply make an analogy, the lion's power is very strong, the dog's power is much weaker in comparison.
