Geometric Deep Learning — Geometric deep learning applies neural networks to data with geometric structures like graphs or manifolds. Imagine teaching a computer to understand the shape of objects in 3D space – it learns patterns in the geometry itself.
Gini Impurity — Gini impurity measures how often a randomly chosen element would be incorrectly labeled if labeled randomly according to the distribution of labels in a dataset. Think of it like measuring how well sorted a box of colored balls is – the more mixed up the colors are, the higher the impurity.
Global Attention — Global attention allows a model to consider all parts of the input when making decisions. Think of it like being able to consider every detail in a painting simultaneously when deciding how to interpret it – nothing is ignored.
Global Feature — A global feature captures information about an entire input rather than just a part. Think of it like looking at an entire painting to understand its overall style, rather than focusing on individual brush strokes.
Global Minimum — A global minimum is the lowest possible value of an error function across all possible parameter values. Imagine finding the deepest point in a landscape – it’s the absolute lowest point, not just a local valley.
Global Optimization — Global optimization seeks to find the best possible solution across an entire problem space. Think of it like searching an entire city for the best restaurant, not just checking a single neighborhood – you’re looking for the absolute best option everywhere.
Global Pooling — Global pooling reduces spatial dimensions by combining features across an entire feature map. Imagine taking a detailed image and summarizing it into a single set of characteristics – you’re capturing the essence of the whole thing.
GPU Acceleration — GPU acceleration uses graphics processing units to speed up AI computations. Imagine having a team of specialized workers (GPU cores) working in parallel instead of a single worker (CPU) – tasks get completed much faster through parallel processing.
Gradient — A gradient measures how much a function’s output changes with respect to its inputs. Think of it like measuring the steepness of a hill – it tells you how quickly you’re going up or down and in which direction.
Gradient Accumulation — Gradient accumulation collects gradients over multiple forward passes before updating model parameters. Think of it like saving up your notes from several lectures before revising your understanding – you’re gathering more information before making changes.
Gradient Boosting — Gradient boosting builds strong predictive models by combining many weak models, focusing on correcting previous mistakes. Imagine learning from a series of tutors, each specializing in the topics you’re struggling with most – each new tutor helps fix the remaining gaps in your knowledge.
Gradient Clipping — Gradient clipping prevents gradients from becoming too large during training. Think of it like having a speed limiter on a car – it prevents the training process from accelerating out of control.
Gradient Descent — Gradient descent is an optimization algorithm that iteratively adjusts parameters to minimize error. Imagine walking down a hill in fog – you keep taking steps in the direction that goes down the most steeply until you reach the bottom.
Grammar Induction — Grammar induction learns the rules of a language or system from examples. Think of it like figuring out the rules of a game by watching others play – you’re discovering the underlying patterns that govern the system.
Graph Attention Network — A graph attention network learns to focus on the most relevant connections in a graph. Imagine having a detective who knows which relationships in a network of people are most important for solving a case – it learns to prioritize the most relevant connections.
Graph Convolution — Graph convolution processes data on irregular graph structures. Think of it like spreading information through a social network – the message passes between connected individuals, but the connections aren’t arranged in a regular grid.
Graph Database — A graph database stores and manages data in terms of nodes and relationships. Imagine organizing information like a mind map – everything is connected through meaningful relationships rather than rigid tables.
Graph Embedding — Graph embedding converts graph-structured data into a format that machine learning models can easily process. Think of it like creating a map where the distances between cities represent how closely they’re connected – you’re converting complex relationships into simpler numerical representations.
Graph Isomorphism — Graph isomorphism determines whether two graphs have the same structure despite looking different. Imagine having two social networks that have the same pattern of connections but with different names – they’re structurally identical despite appearing different.
