Random Forest
An ensemble learning method that combines multiple decision trees to make predictions. Picture a crowd of experts each making a decision, then voting on the final outcome.
Random Search
A hyperparameter optimization technique that tries random combinations of settings. Similar to trying different recipe ingredients at random to discover new flavor combinations.
Random Walk
In machine learning, a sequence of random steps used to explore data or parameter spaces. Like a treasure hunt where each next step is chosen by chance.
Ranking
A technique that orders items based on their relevance or importance. Imagine a search engine arranging results from most to least relevant to your query.
Recall
A metric measuring the proportion of actual positive cases correctly identified. Like a security system’s ability to catch all genuine threats without missing any.
Receptive Field
The region of input data that affects a particular node in a neural network. Similar to the area of vision that influences what a single eye cell sees.
Recognition
The ability to identify and classify patterns, objects, or sequences. Picture a system that can distinguish different breeds of dogs in photographs.
Recommendation System
An algorithm that suggests items or content based on user preferences and behavior. Like a knowledgeable friend who knows your tastes and suggests new movies you might enjoy.
Reconstruction Error
The difference between original input and its reproduction after processing. Imagine comparing an original photo with its compressed and then decompressed version.
Regression
A technique for predicting continuous numerical values based on input features. Like predicting a house’s price based on its size, location, and other characteristics.
Regularization
A technique to prevent overfitting by adding constraints to the learning process. Similar to adding training wheels to help maintain balance while learning to ride a bike.
Reinforcement Learning
A learning approach where agents learn optimal actions through trial and error with rewards and penalties. Picture teaching a dog new tricks by rewarding desired behaviors.
Rejection Sampling
A technique for generating samples from a complex probability distribution. Like carefully selecting survey participants to ensure they represent the whole population.
ReLU (Rectified Linear Unit)
An activation function that outputs the input directly if positive, and zero otherwise. Imagine a gate that lets positive signals through unchanged but blocks negative ones.
Representation Learning
The ability to automatically discover useful data representations for tasks. Like learning to recognize the key features that distinguish different types of music.
Residual Connection
A network architecture that allows direct data flow between non-adjacent layers. Picture a highway that lets information skip through traffic by providing a direct route.
Residual Network
A deep neural network architecture that uses skip connections to prevent vanishing gradients. Similar to creating shortcuts in a tall building to make movement more efficient.
Resolution
In the context of AI models, the level of detail or granularity in data processing. Like adjusting a microscope to see finer or broader details.
Response Time
The duration between receiving input and producing output in an AI system. Picture the delay between asking a question and receiving an answer from a digital assistant.
Restricted Boltzmann Machine
A two-layer neural network that learns to reconstruct input data. Like an artist learning to recreate scenes from memory.
Reward Function
In reinforcement learning, a function that defines the value of different actions or states. Imagine a scoring system that tells a game-playing AI which moves are better than others.
Risk Assessment
A technique for evaluating potential problems or failures in AI systems. Similar to a safety inspector checking for possible hazards before approving a new ride.
RNN (Recurrent Neural Network)
A neural network designed to work with sequential data by maintaining an internal memory. Picture a reader who remembers earlier parts of a story to understand later chapters.
Robustness
A model’s ability to perform well despite variations or noise in input data. Picture a face recognition system that works reliably under different lighting conditions.
ROC Curve
A graph showing the trade-off between true positive and false positive rates. Like a dashboard showing how adjusting a security system’s sensitivity affects its accuracy.
