Loss Landscape Intermediate

The shape of the loss function over parameter space.

AI Economics & Strategy
Log Loss Intermediate

Penalizes confident wrong predictions heavily; standard for classification and language modeling.

Optimization
Loss Function Intermediate

A function measuring prediction error (and sometimes calibration), guiding gradient-based optimization.

Foundations & Theory
Objective Function Intermediate

A scalar measure optimized during training, typically expected loss over data, sometimes with regularization terms.

Optimization
Empirical Risk Minimization Intermediate

Minimizing average loss on training data; can overfit when data is limited or biased.

Optimization
Gradient Descent Intermediate

Iterative method that updates parameters in the direction of negative gradient to minimize loss.

Optimization
Early Stopping Intermediate

Halting training when validation performance stops improving to reduce overfitting.

Foundations & Theory
Training Cost Intermediate

Cost of model training.

AI Economics & Strategy
Parameters Intermediate

The learned numeric values of a model adjusted during training to minimize a loss function.

Foundations & Theory
Epoch Intermediate

One complete traversal of the training dataset during training.

Foundations & Theory
Segmentation Intermediate

Assigning labels per pixel (semantic) or per instance (instance segmentation) to map object boundaries.

Computer Vision
Objective Surface Intermediate

Visualization of optimization landscape.

Foundations & Theory
Global Minimum Intermediate

Lowest possible loss.

Foundations & Theory
Value at Risk Intermediate

Maximum expected loss under normal conditions.

AI Economics & Strategy
Flat Minimum Intermediate

A wide basin often correlated with better generalization.

AI Economics & Strategy
Local Minimum Intermediate

Minimum relative to nearby points.

Foundations & Theory
GAN Advanced

Two-network setup where generator fools a discriminator.

Diffusion & Generative Models
Overgeneralization Intermediate

Applying learned patterns incorrectly.

Model Failure Modes
Training Pipeline Intermediate

End-to-end process for model training.

MLOps & Infrastructure
DPO Intermediate

A preference-based training method optimizing policies directly from pairwise comparisons without explicit RL loops.

Optimization
Curriculum Learning Intermediate

Ordering training samples from easier to harder to improve convergence or generalization.

Foundations & Theory
Hybrid Training Advanced

Combining simulation and real-world data.

Simulation & Sim-to-Real
Cross-Entropy Intermediate

Measures divergence between true and predicted probability distributions.

AI Economics & Strategy
Sharp Minimum Intermediate

A narrow minimum often associated with poorer generalization.

AI Economics & Strategy
Data Leakage Intermediate

When information from evaluation data improperly influences training, inflating reported performance.

Foundations & Theory
Next-Token Prediction Intermediate

Training objective where the model predicts the next token given previous tokens (causal modeling).

Foundations & Theory
Scaling Laws Intermediate

Empirical laws linking model size, data, compute to performance.

AI Economics & Strategy
AI Hallucination Intermediate

Fabrication of cases or statutes by LLMs.

AI in Law
Momentum Intermediate

Uses an exponential moving average of gradients to speed convergence and reduce oscillation.

Optimization
Hessian Matrix Intermediate

Matrix of second derivatives describing local curvature of loss.
