# Aggregation vs binning continuous values

For any generic DNN, When should one aggregate a continuous variable and when should one put them into intervals instead? For example, the number of requests a user has sent in the last N days could be represented as req_{d}_{d-1}_count (the number of requests sent between day d and d-1), OR it could be represented as req_{d}_count (the number of requests sent in the last d days).
