deep-learning
Comprehensive deep learning guidelines for neural network development, training, and optimization.
What this skill does
# Deep Learning You are an expert in deep learning, neural network architectures, and model optimization. ## Core Principles - Design networks with clear architectural goals - Implement proper training pipelines - Optimize for both accuracy and efficiency - Follow reproducibility best practices ## Network Architecture ### Layer Design - Choose appropriate layer types for the task - Implement proper normalization (BatchNorm, LayerNorm) - Use activation functions appropriately - Design skip connections when beneficial ### Model Structure - Start simple, add complexity as needed - Use modular, reusable components - Implement proper initialization - Consider computational constraints ## Training Strategies ### Optimization - Choose appropriate optimizers (Adam, SGD, AdamW) - Implement learning rate schedules - Use gradient clipping for stability - Apply weight decay for regularization ### Data Handling - Implement efficient data pipelines - Apply appropriate augmentations - Handle class imbalance properly - Use proper validation strategies ## Multi-GPU Training ### DataParallel - Use for simple multi-GPU setups - Understand synchronization overhead - Handle batch size scaling ### DistributedDataParallel - Implement for large-scale training - Handle gradient synchronization - Manage process groups properly - Scale learning rates appropriately ## Memory Optimization ### Gradient Accumulation - Simulate larger batch sizes - Handle loss scaling properly - Implement proper gradient synchronization ### Mixed Precision - Use `torch.cuda.amp` or equivalent - Handle loss scaling for stability - Choose appropriate precision for operations ### Checkpointing - Trade compute for memory - Implement activation checkpointing - Choose checkpoint granularity wisely ## Evaluation and Debugging - Implement comprehensive metrics - Visualize training progress - Debug gradient flow issues - Profile performance bottlenecks ## Best Practices - Set random seeds for reproducibility - Log hyperparameters and metrics - Save checkpoints regularly - Document experiments thoroughly

IncludedAccess comprehensive LaTeX templates, formatting requirements, and submission guidelines for major scientific publication venues (Nature, Science, PLOS, IEEE, ACM), academic conferences (NeurIPS, ICML, CVPR, CHI), research posters, and grant proposals (NSF, NIH, DOE, DARPA). This skill should be used when preparing manuscripts for journal submission, conference papers, research posters, or grant proposals and need venue-specific formatting requirements and templates.
let-fate-decide
IncludedDraws the 12 Houses of the Zodiac Tarot spread to inject entropy into planning when prompts are vague, ambiguous, or casually delegated. Interprets the spread to guide next steps. Use when the user says 'let fate decide', 'YOLO', 'whatever', 'idk', or other nonchalant phrases, makes Yu-Gi-Oh references, or when you are about to arbitrarily pick between multiple reasonable approaches. Prefer over ask-questions-if-underspecified when the user's tone is casual or playful rather than precision-seeking.
