YingHub-v3

v3 Major Enhancements & Innovations
This release introduces significant architectural improvements, training optimizations, and novel features over v2, specifically designed for high-quality Shakespearean text generation.


🚀 Key Advancements (v3 vs v2)

1. Data Loading & Preprocessing Optimizations

  • Sliding Window Pre-computation
    Implemented memory-efficient unfold + circular buffer strategies to handle variable-length sequences

  • Dynamic Mask Augmentation
    10% random token masking with <unk> during batch generation improves robustness

  • Streaming Dataset Iterator
    Memory-mapped data loading with zero-copy tensor conversion (4x faster than v2's disk I/O)

2. Architectural Upgrades

  • Flash Attention Integration
    Implemented Triton-accelerated Flash Attention kernels (2.1x faster than standard PyTorch attention).
  • Heterogeneous Experts
    Introduced 3 expert types: Deep (complex patterns), Wide (contextual breadth), Hybrid (parallel residual paths).
  • Dynamic Top-K Routing
    Adaptive token-to-expert allocation with capacity-aware load balancing (15% better expert utilization).

3. Training Optimizations

  • Factorized Embeddings
    Low-rank embeddings + projection layers reduce memory usage by 40% with <1% accuracy drop.
  • Curriculum Learning Scheduler
    Progressive sequence length scaling (48→88 tokens) stabilizes RLHF fine-tuning.
  • Structured Dropout
    Block-wise dropout (20%) + Structural embedding dropout (20%) + Attention dropout (30%) + gradient clipping (norm=1.2) prevents overfitting.

4. Controlled Generation

  • Dramatic Structure Enforcement
    State machine tracking for <SCENE>, <SPEAKER>, and <STAGE> tag consistency.
  • Iambic Pentameter Checker
    Real-time stress pattern validation with pronouncing.py integration.
  • Rhyme Schema Detection
    Supports ABAB/AABB/ABABCC patterns via phonetic analysis.

5. Data Pipeline

  • Enhanced Shakespeare Cleaning
    Specialized regex patterns for:
    • Speaker turn management (<SPEAKER>...</SPEAKER>)
    • Stage direction isolation (<STAGE>[...]</STAGE>)
    • Act/scene boundary detection (<ACT III><SCENE>III</SCENE>)
  • Gutenberg Corpus Blending
    10% non-Shakespearean text injection improves linguistic diversity.
