+
+## Salvageable Content (In Git History at 366684d)
+
+### Quick Wins - Classic Algorithms (~40 hours each)

+- From-scratch: Implement SVM with gradient descent on hinge loss
+- Practical: Kernel comparison (linear, RBF, polynomial), hyperparameter C/gamma tuning
+- References: MIT 6.034, Stanford CS229 lectures on SVM
+
+**Lesson 5: K-Nearest Neighbors**
+- Current state: 5.7KB stub, 6 math symbols
+- Needs: Distance metrics (Euclidean, Manhattan, Minkowski), KD-tree mathematics, curse of dimensionality
+- From-scratch: Implement KNN with KD-tree for efficiency
+- Practical: Optimal K selection via cross-validation, weighted voting
+- References: ESL Chapter 13, Hastie et al.
+
+**Lesson 6: Naive Bayes**
+- Current state: 6.2KB stub, 8 math symbols
+- Needs: Bayes' theorem derivation, conditional independence assumption, Gaussian/Multinomial/Bernoulli variants
+- From-scratch: Implement Gaussian NB with MLE parameter estimation
+- Practical: Text classification with TF-IDF, Laplace smoothing
+- References: Murphy's "Machine Learning: A Probabilistic Perspective" Chapter 3
+
+### Medium Effort (~40-50 hours each)
+
+**Lesson 7: Ensemble Methods**
+- Current state: 7.9KB stub, 4 math symbols
+- Needs: Bias-variance decomposition, bagging mathematics, AdaBoost derivation, gradient boosting theory
+- From-scratch: Implement AdaBoost from scratch
+- Practical: XGBoost, LightGBM with hyperparameter tuning strategies
+- References: ESL Chapter 10, Friedman's gradient boosting papers
+
+**Lesson 8: Anomaly Detection**
+- Current state: 6.0KB stub, 3 math symbols
+- Needs: Gaussian distribution modeling, Mahalanobis distance, Isolation Forest mathematics, One-Class SVM theory
+- From-scratch: Implement Gaussian anomaly detection
+- Practical: Fraud detection case study, ROC curve analysis for imbalanced data
+- References: Chandola et al. "Anomaly Detection: A Survey"
+
+### Major Rewrites - Deep Learning (~60-80 hours each)
+
+**Lesson 9a: Convolutional Neural Networks**
+- Current state: 0 math, PyTorch tutorial with emojis (🚀✅)
+- Needs complete rewrite:
+  - Discrete convolution mathematical definition
+  - Backpropagation through convolutional layers (chain rule application)
+  - Pooling layer gradient derivation
+  - Weight sharing and parameter reduction mathematics
+- From-scratch: CNN in NumPy (forward + backward pass)
+- Practical: Image classification, transfer learning theory (feature reuse mathematics)
+- References: Stanford CS231n, Goodfellow's Deep Learning Book Chapter 9
+
+**Lesson 9b: Recurrent Neural Networks**
+- Current state: 0 math, PyTorch tutorial
+- Needs complete rewrite:
+  - Backpropagation Through Time (BPTT) derivation
+  - Vanishing/exploding gradient mathematics
+  - LSTM gate equations and gradient flow
+  - GRU simplification and performance trade-offs
+- From-scratch: RNN + LSTM in NumPy
+- Practical: Sequence modeling, time series forecasting
+- References: Goodfellow Chapter 10, Hochreiter & Schmidhuber LSTM paper
+
+**Lesson 9c: Transformers & Attention**

+  - Scaled dot-product attention mathematical derivation

+- From-scratch: Attention mechanism in NumPy, scaled dot-product implementation

+
+### Not Worth Salvaging - X-Series
+
+**Why delete X-series:**
+- Wrong pedagogical format (meta-lessons about tools vs mathematical foundations)
+- Corporate training approach (slideshows, not derivations)
+- Should be integrated into practical notebooks, not separate lessons
+
+**Better approach:**
+- **Feature engineering** → Integrate into 2b (decision trees practical) and other "b" notebooks
+- **Model evaluation** → Cover in each practical notebook (confusion matrix, ROC, precision/recall)
+- **Hyperparameter tuning** → Show grid search/Bayesian optimization in context (e.g., 4b SVM)
+- **Imbalanced data** → Discuss in 8b (anomaly detection practical)
+- **Interpretability** → Add SHAP/LIME to 2b (tree-based interpretability)
+- **Ethics/bias** → Dedicated section in 1b or 6b (classification fairness)
