Human behaviour recognition in data-scarce domains

Highlights:

• We challenge the notion that the exact temporal structure of activities needs to be modelled.

• We compare performance against a Hidden Markov Model baseline.

• The weak temporal structure of our approach makes it less sensitive to observation order.

• Hidden Markov Models cannot be used to classify some activity sequences.

• Our approach outperforms the baseline by 17%.
