    "This notebook demonstrates the key computational workflows from the TranscriptFormer paper:\n",
    "\n",
    "1. **TranscriptFormer Architecture**: Autoregressive generative model for single-cell transcriptomics\n",
    "2. **Cell Embedding Generation**: Extract cell-level and gene-level representations\n",
    "3. **Cross-Species Transfer Learning**: Cell type classification and annotation transfer\n",
    "4. **Contextualized Gene Embeddings (CGEs)**: Context-aware gene representations\n",
    "5. **Gene-Gene Interaction Prediction**: Using the model as a \"virtual instrument\"\n",
    "6. **Linear Probing Evaluation**: Standard protocol for evaluating embeddings\n",
    "\n",
    "**Note**: This is an educational notebook using small-scale synthetic data to demonstrate the methods within resource constraints (4GB RAM, ~10 minute runtime). Full-scale experiments would require GPU clusters and hours/days of computation.\n",
