Our review
Pros
  • Supports training, fine-tuning, testing, scoring, and layer-by-layer benchmarking
  • Runs on CPU or CUDA GPUs, including multi-GPU training
  • Provides Python and MATLAB interfaces for models and solver operations
  • CPU and CUDA GPU acceleration through ND4J
  • Distributed training, evaluation, and inference with Apache Spark
  • Keras and TensorFlow frozen-model import for JVM projects
Cons
  • Requires local compilation for self-hosted deployment
  • Documentation is dated, so environment compatibility needs careful review
  • Feature set is narrower than modern general-purpose deep learning frameworks
  • Self-hosted deployment requires teams to manage their own infrastructure
  • Support is provided through the community channel
  • Workflow breadth is narrower than broader deep-learning suites
