In the interest of interspecies cooperation his two dogs Mink and Clifford have generously volunteered to take his place. For those of you not familiar with them they have appeared on these pages twice before Mink is a large chocolate labrador retriever Clifford is a small spaniel poodle mixed breed. In intelligence and character Mink is basically a noble albeit constantly hungry human being in a canine body. Clifford is - well a dog. Mink Clifford did you see that a Hungarian scientist one Csaba Molnar has been developing a computer program to analyze dog s barks There s even a paper about it Molnar C et al. Classification of dog barks a machine learning approach. Animal Cognition 2008 doi s10071-007-0129-9 . Clifford What does the paper say Mink Here s the abstract In this study we analyzed the possible context-specific and individual-specific features of dog barks using a new machine-learning algorithm. A pool containing more than 6 000 barks which were recorded in six different communicative situations was used as the sound sample. The algorithm s task was to learn which acoustic features of the barks which were recorded in different contexts and from different individuals could be distinguished from another. The program conducted this task by analyzing barks emitted in previously identified contexts by identified dogs. After the best feature set had been obtained with which the highest identification rate was achieved the efficiency of the algorithm was tested in a .
