The study described in this paper developed a model of animal movement, which explicitly recognised each individual as the central unit of measure. The model was developed by learning from a real dataset that measured and calculated, for individual cows in a herd, their linear and angular positions and directional and angular speeds. Two learning algorithms were implemented: a Hidden Markov Model (HMM) and a long-term prediction-learning algorithm. It is shown that a HMM can be used to describe

Model parameters were estimated for hidden behaviour states such as relocating, foraging and bedding. For cows' movement between the "stay" areas a long-term prediction algorithm was implemented. By combining these two algorithms it was possible to develop a successful model, which achieved similar results to the animal behaviour data collected. This modelling methodology could easily be applied to interactions of other animal species. We thank the reviewers for their valuable comments. The paper has been significantly revised according to the reviewers' suggestions. We are now submitting the revised paper for your consideration. Please let me know if you need other materials. Thank you.
