I have a set of binary vectors where each vector represents one day of occupancy in a house and consists of 48 elements (each element for 30 minutes of the day). Each element can be 1 meaning that house was occupied and 0 for non occupied house.

My task is to predict the next day based on the history of the same days (Monday from history of Mondays etc.). So far I am using hamming distance to find 5 most similar days in the history and from them I calculate the probabilities of the occupancy as a mean of those 5 numbers. When the probability is higher than some X, in my case 0.4, I predict it to be occupied.

But there is definitely some more efficient way to do this, any algorithms that would capture the trend in the history?
