Red spikes indicate memory pressure points that optimization techniques address.

Use Cases and Recommendations:

Decision matrix mapping use cases to recommended techniques. The flowchart guides users: "Training large models?" → Reversible CNNs. "Deployment on edge devices?" → Spiking Neural Networks. "Extreme memory constraints?" → ActNN. "Need highest accuracy?" → Modern Hopfield Networks. Each recommendation includes expected memory savings, accuracy trade-offs, and implementation complexity ratings.

Detailed Techniques:

In-depth technical breakdown of each memory-efficient technique. For each method, the visualization shows: (1) Architecture diagram, (2) Memory flow, (3) Computational graph, (4) Key equations, (5) Implementation pseudocode. Color-coded arrows trace data flow, with red indicating checkpoints, blue for forward pass, green for backward pass. Essential reference for implementation.

Memory Timeline:

Training memory usage timeline comparing baseline vs optimized approaches. The x-axis shows training iterations (0-1000), y-axis shows GPU memory in GB. Baseline (red line) shows sawtooth pattern with peaks at 8.2GB. Optimized (blue line) remains flat at 2.8GB—66% reduction. The shaded regions indicate standard deviations, with optimized showing more stable memory consumption.

Learning Path:

Recommended learning progression through memory-efficient techniques. Start with "Fundamentals" (understanding memory hierarchy) → "Basic Techniques" (gradient checkpointing, mixed precision) → "Intermediate" (reversible networks, quantization) → "Advanced" (ActNN, SNNs, DNCs) → "Expert" (custom techniques, research). Each level shows estimated learning time, prerequisites, and expected competency gained. Color bars indicate difficulty level.

Key Results: 50-90% memory savings depending on technique, reversible CNNs best for large models, ActNN best for extreme constraints

5. Test-Time Adaptation Works: TTT provides 300% improvement on novel tasks without retraining
6. Systematic Evaluation Matters: Comprehensive benchmarks (200+ visualizations) prove all claims with data
