Anomaly Detection
In machine learning, anomaly detection is the process of identifying data points, events, or observations that deviate significantly from normal patterns in a dataset.
Bioinformatics
Bioinformatics is the branch of science that builds computational methods, databases, and software for storing, searching, and interpreting biological data, above all the sequences of DNA, RNA, and proteins…
Concept drift
Concept drift is the change over time in the statistical relationship between a model's inputs and its target, formally when the joint distribution P(X, Y) (and in the most damaging case the conditional P(Y |…
Confirmation Bias
Confirmation bias is the tendency to search for, interpret, favor, and recall information in ways that confirm one's preexisting beliefs, and in artificial intelligence it appears in three main forms: human…
DBSCAN
DBSCAN (Density-Based Spatial Clustering of Applications with Noise) is a density-based clustering algorithm that groups together points packed closely in feature space and labels points in low-density regions…
Dask
Dask is an open-source Python library for parallel and distributed computing that scales the familiar APIs of libraries such as NumPy, pandas, and scikit-learn to process larger-than-memory datasets.
Data Analysis
Data analysis is the process of inspecting, cleaning, transforming, and modeling data to discover useful information, draw conclusions, and support decision-making.
Data Analysis ChatGPT Plugins
Data analysis ChatGPT plugins were a category of third-party tools that extended ChatGPT with capabilities for analysts, data scientists, and finance professionals working with structured data in a chat…
Data Visualization
Data visualization is the graphical representation of information and data through charts, plots, maps, and dashboards.
Data Visualization ChatGPT Plugins
Data visualization ChatGPT plugins were a category of third party tools, active from 2023 to 2024, that let ChatGPT draw charts, plot graphs, render flowcharts, and build other visual representations of data…
Data labeling
Data labeling (also called data annotation) is the process of attaching meaningful tags, labels, or metadata to raw data so that machine learning algorithms can learn from it.
DataFrame
A DataFrame is a two-dimensional, size-mutable, potentially heterogeneous tabular data structure with labeled axes (rows and columns), in which each column can hold a different data type and arithmetic…
Dimensionality reduction
Dimensionality reduction is the process of transforming data from a high-dimensional space into a lower-dimensional representation that retains as much of the meaningful structure of the original data as…
Feature Set
A feature set is the complete collection of input variables (features, attributes, or predictors) that a machine learning model uses to learn patterns and make predictions.
Julius AI
Julius AI is an artificial intelligence data analysis platform that allows users to analyze datasets, generate visualizations, and perform statistical computations through natural language conversations.
Kaggle
Kaggle is the world's largest online community and platform for data scientists and machine learning practitioners, where companies and researchers post datasets and contestants compete to build the most…
Matplotlib
Matplotlib is the foundational open-source data visualization library for Python, created by John D. Hunter in 2003, that produces static, animated, and interactive plots and serves as the de-facto plotting…
Multiple sequence alignment
A multiple sequence alignment (MSA) arranges three or more biological sequences, usually proteins, DNA or RNA
NVIDIA Nemotron Model Reasoning Challenge
The NVIDIA Nemotron Model Reasoning Challenge was a Kaggle competition run by NVIDIA from March to June 2026 in which participants tried to improve the reasoning accuracy of a fixed open model, Nemotron 3 Nano…
Pandas
Pandas is an open-source data analysis and manipulation library for the Python programming language, providing high-performance, flexible data structures designed for working with structured (tabular…

Research & Analysis
Research & Analysis in the AI sense refers to the use of artificial intelligence, especially large language models paired with retrieval-augmented generation, to find information, read sources, summarise…
Synthetic Feature
A synthetic feature (also called a constructed feature or derived feature) is a variable created by transforming, combining, or otherwise manipulating one or more existing features in a dataset, rather than…
Tabular models
Tabular models are machine learning systems that learn from data arranged in tables, where each row is a sample and each column is a feature.
TensorBoard
TensorBoard is the open-source visualization toolkit for TensorFlow, described by Google as "a suite of visualization tools to understand, debug, and optimize TensorFlow programs for ML experimentation." It…
Time Series
A time series is a sequence of observations recorded in time order, often at regular intervals: daily retail sales, hourly electricity demand, per-minute server latency, quarterly GDP.
Time Series Analysis
Time series analysis is the statistical study of ordered observations when dependence across time is part of the signal rather than a nuisance to ignore.
UMAP (Uniform Manifold Approximation and Projection)
UMAP (Uniform Manifold Approximation and Projection) is a nonlinear dimensionality reduction technique that compresses high-dimensional data into a low-dimensional map (typically 2 or 3 dimensions) while…
Unsupervised learning
Unsupervised learning is a branch of machine learning in which algorithms identify patterns, structures, and relationships in data without relying on labeled examples or explicit human guidance.
