|
|
\textbf{Chirps} are the most common communication signals in weakly electric fish. They are characterized by \textbf{short frequency excursions} and are emitted during various social contexts. It is nearly impossible to reliably \textbf{detect and assign} chirps in freely interacting fish using only a Fourier transform. To overcome these limits, we developed a new method of \textbf{dynamic feature extraction} and classification.

|
|
\begin{itemize}
|
|
\setlength\itemsep{0.5em}
|
|
\item First tests indicate that our algorithm is able to detect chirps in recordings of multiple fish.
|
|
\item In some cases the chirp rate drastically increases before chasing stops.
|
|
\item Behavioral analysis needs to consider more variables, such as sex, size, and interindividual differences in chirping behavior.
