Abstract: We present a systematic exploration of convolutional neural network architectures
for predicting DNA sequence binding using a large compendium of transcription
factor datasets. We identify the best-performing architectures by varying convolutional
neural network width, depth, and pooling designs. We find that adding
convolutional kernels to a network is important for motif discovery and the use
of local max-pooling is important for differentiating bound versus unbound sequences
when both sequences contain a factor’s cognate motif. We explore the
sufficiency of training data in the performance of these learning approaches, and
have created a flexible cloud-based framework that permits the rapid exploration
of alternative neural network architectures for problems in computational biology.
