Trying to find the right search terms for literature on classifying 2D time series data.
I am looking at data from positional tracking of a swarm of insects over time. I have example datasets for specific insect behaviors, and I would like to play around with training a classifier on these.
You might be interested in RNNs (e.g., LSTMs) or Hidden Markov models. RNNs can be used directly for classification. HMMs can be used to build a generative model for each class, which can then be used for classification: if $x$ is the observed 2D time series, the model for class $c$ lets you compute $P(x|c)$, and then you can classify $x$ by selecting the class $c$ that maximizes $P(x|c)$ (the maximum likelihood principle).
The one-nearest neighbor classifier is very competitive for time series. http://www.cs.ucr.edu/~eamonn/ICML2006.pdf If you want code or data, I have lots of both. eamonn
