Plan recommendations per user powered by a multi-class neural network a deep learning algorithm. This Neural networks (which have been named over the human brain neural networks) recommends the most likely plans to be subscripted by a user based on his actions by giving the available plans probabilities of being subscribed by user , and recommending the highest probable plans.
A neural network with 3 recommendation outputs (e.g. plans) and 4 inputs (user features & activities).
