Results for "loss"

Loss Function

Intermediate

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

A loss function is like a scorekeeper for a machine learning model, telling it how well it is doing at making predictions. Imagine you are trying to guess the weight of a bag of apples. If you guess too high or too low, the loss function measures how far off your guess was from the actual weight....

Generalization Intermediate

How well a model performs on new data drawn from the same (or similar) distribution as training.

Foundations & Theory
Calibration Intermediate

The degree to which predicted probabilities match true frequencies (e.g., 0.8 means ~80% correct).

Foundations & Theory
Learning Rate Intermediate

Controls the size of parameter updates; too high diverges, too low trains slowly or gets stuck.

Foundations & Theory
Epoch Intermediate

One complete traversal of the training dataset during training.

Foundations & Theory
Neural Network Intermediate

A parameterized function composed of interconnected units organized in layers with nonlinear activations.

Neural Networks
Next-Token Prediction Intermediate

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

Foundations & Theory
Vanishing Gradient Intermediate

Gradients shrink through layers, slowing learning in early layers; mitigated by ReLU, residuals, normalization.

Foundations & Theory
Masked Language Model Intermediate

Predicts masked tokens in a sequence, enabling bidirectional context; often used for embeddings rather than generation.

Foundations & Theory
Context Window Intermediate

Maximum number of tokens the model can attend to in one forward pass; constrains long-document reasoning.

Transformers & LLMs
Few-Shot Learning Intermediate

Achieving task performance by providing a small number of examples inside the prompt without weight updates.

Foundations & Theory
SFT Intermediate

Fine-tuning on (prompt, response) pairs to align a model with instruction-following behaviors.

Foundations & Theory
DPO Intermediate

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

Optimization
Reward Model Intermediate

Model trained to predict human preferences (or utility) for candidate outputs; used in RLHF-style pipelines.

Foundations & Theory
LIME Intermediate

Local surrogate explanation method approximating model behavior near a specific input.

Foundations & Theory
Curriculum Learning Intermediate

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

Foundations & Theory
Quantization Intermediate

Reducing numeric precision of weights/activations to speed inference and reduce memory with acceptable accuracy loss.

Foundations & Theory
Pruning Intermediate

Removing weights or neurons to shrink models and improve efficiency; can be structured or unstructured.

Foundations & Theory
Convex Optimization Intermediate

Optimization problems where any local minimum is global.

AI Economics & Strategy
Backdoor / Trojan Intermediate

Hidden behavior activated by specific triggers, causing targeted mispredictions or undesired outputs.

Foundations & Theory
Non-Convex Optimization Intermediate

Optimization with multiple local minima/saddle points; typical in neural networks.

AI Economics & Strategy
Second-Order Methods Intermediate

Optimization using curvature information; often expensive at scale.

AI Economics & Strategy
Scaling Laws Intermediate

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

AI Economics & Strategy
Variational Autoencoder Advanced

Autoencoder using probabilistic latent variables and KL regularization.

Diffusion & Generative Models
Mode Collapse Advanced

Generator produces limited variety of outputs.

Diffusion & Generative Models
Image Classification Intermediate

Assigning category labels to images.

Computer Vision
CLIP Intermediate

Joint vision-language model aligning images and text.

Computer Vision
Neural Vocoder Intermediate

Generates audio waveforms from spectrograms.

Speech & Audio AI
Gradient Advanced

Direction of steepest ascent of a function.

Mathematics
Feedback Loop Intermediate

Using production outcomes to improve models.

MLOps & Infrastructure
Saddle Plateau Intermediate

Flat high-dimensional regions slowing training.
