abstract = "Aiming at solving the existing problems of radar
signal recognition methods, this paper presents a
method based on Tree-based Pipeline Optimization Tool
(TPOT) and Local Interpretable Model-agnostic
Explanations (LIME). This method uses genetic
programming based on the tree structure to generate the
machine learning pipeline. The structure and parameters
are evolved to obtain the optimal performance of the
machine learning pipeline. Then the prediction results
are interpreted by the interpreter to evaluate whether
the model is available. When there are multiple signals
with similar interpretative properties, it shows that
these signals are indistinguishable. The prediction
results are interpreted on this model which was
re-trained for indistinguishable signals to validate
the validity of the LIME interpreter. The experimental
results show that the proposed method can not only
optimize the machine learning pipeline for different
data sets, but also determine the type of
indistinguishable radar signal in the data set
according to the interpretability.",
