deepRAM

deepRAM predicts DNA and RNA binding specificities using convolutional neural networks (CNNs), recurrent neural networks (RNNs), and hybrid CNN/RNN deep learning architectures.

Key Features:

• Comprehensive Architectural Exploration: Implements convolutional neural networks (CNNs), recurrent neural networks (RNNs), and hybrid CNN/RNN architectures to enable systematic comparison of model architectures.
• Automatic Model Selection: Employs a fully automatic model selection strategy for unbiased selection and comparison of architectures.
• Performance Insights: Systematic evaluation identifies that deeper and more complex architectures, particularly hybrid CNN/RNN models, achieve superior accuracy when sufficient training data are available.
• Interpretability Considerations: Documents a trade-off where RNN-based architectures improve prediction accuracy but reduce clarity of learned sequence features relative to convolutional networks.

Scientific Applications:

• ChIP-seq and CLIP-seq Data Analysis: Applied to ChIP-seq and CLIP-seq datasets to predict protein–DNA and protein–RNA binding sites and specificities.
• DNA/RNA Binary Classification: Applicable to general DNA/RNA sequence binary classification tasks for genomic research.

Methodology:

Integrates data preprocessing, model training, evaluation, and an automatic model selection mechanism for empirical performance-based comparison of architectures.
