What this task asks for
Build BVLC Caffe 1.0.0 for CPU execution and train CIFAR-10 for exactly 500 iterations while meeting the stated accuracy bounds. Build Caffe for CPU-only execution. Train for exactly 500 iterations. Evaluate over 100 test iterations. Achieve test accuracy above 45% and within five percentage points of train accuracy.
Intent
- systems setup
- model training
- test and validation
Work surfaces
