Artificial intelligence and data

T-3000

The T-3000 is a fictional Terminator model in the 2015 film Terminator Genisys, where Skynet converts resistance leader John Connor into a nanocyte cyborg assassin.

T-distributed stochastic neighbor embedding

T-distributed stochastic neighbor embedding (t-SNE) is a nonlinear dimensionality-reduction technique that visualizes high-dimensional data in two- or three-dimensional maps, introduced by Laurens van der Maaten and Geoffrey Hinton in 2008.

T-X

The T-X, or Terminatrix, is a fictional cyborg assassin in the Terminator franchise, introduced in Terminator 3: Rise of the Machines (2003), played by Kristanna Loken.

Table (database)

A table in a database, also called a database table, is a named collection of data organized into rows and columns, where each row is a single record.

Table (information)

A table, also known as a data table, is a two-dimensional arrangement of data in rows and columns, where each row describes one thing and each column one property.

TabPFN

TabPFN (Tabular Prior-data Fitted Network) is a transformer-based foundation model for tabular data, introduced in 2022 and described in Nature in 2025 by University of Freiburg researchers.

Tabu search

Tabu search, or the tabu search algorithm, is a metaheuristic optimization method introduced by Fred Glover in 1986 that uses memory of recent moves to escape local optima.

Tabular (company)

Tabular (Tabular Technologies, Inc.), also styled Tabular.io, was a 2021 San Jose data management startup founded by Apache Iceberg creators Ryan Blue, Daniel Weeks, and Jason Reid; Databricks acquired it in June 2024 for a reported $1-2 billion.

Takagi–Sugeno fuzzy model

The Takagi–Sugeno fuzzy model, also called the Sugeno fuzzy model, represents nonlinear systems as fuzzy blends of local linear models, introduced by Takagi and Sugeno in 1985.

Talend Open Studio

Talend Open Studio (TOS) was Talend's free, open-source ETL and data integration tool, launched October 2006 under GPLv2 with over 20 million downloads; Qlik retired it January 31, 2024 after acquiring Talend in May 2023.

Task arithmetic

Task arithmetic is a technique for editing trained neural networks directly in weight space: task vectors, the differences between fine-tuned and pre-trained weights, are added, subtracted, or combined.

Task parallelism

Task parallelism is a parallel computing approach that distributes different independent tasks across processors to run at the same time, unlike data parallelism, which applies one operation to different data.

Tatoeba

Tatoeba, from the Japanese for "for example", is a free community database of translated example sentences founded in 2006, holding over 13 million sentences in 400+ languages.

TC0

TC0, also written TC⁰, is a circuit complexity class of polynomial-size, constant-depth circuits of majority (threshold) gates, defined by Hajnal, Maass, Pudlák, Szegedy, and Turán in 1987.

TCAV (machine learning)

TCAV, or Testing with Concept Activation Vectors, is an interpretability method that quantifies how strongly human-defined concepts like stripes influence a neural network's predictions, introduced by Been Kim and colleagues at ICML 2018.

Teaching–learning-based optimization

Teaching–learning-based optimization (TLBO) is a population-based metaheuristic that mimics classroom teaching and peer learning, proposed by R. V. Rao and colleagues in 2011 and used mainly for engineering design.

Tears in rain monologue

The Tears in rain monologue is a 42-word speech by Rutger Hauer as replicant Roy Batty near the end of Blade Runner (1982), closing with "Time to die."

Tech noir

Tech noir, also called future noir, is a hybrid film genre blending film noir with science fiction, named by James Cameron for a nightclub in The Terminator (1984).

Technological singularity

The technological singularity, also called Vinge's singularity or the AI singularity, is a hypothesized point when self-improving AI rapidly surpasses human intelligence, making events beyond it unforeseeable.

Tecton (company)

Tecton (Tecton, Inc.), also TectonAI, was a San Francisco feature platform company founded by ex-Uber Michelangelo engineers; raised a $20M Series A in 2020, reached Series C, and was acquired by Databricks in August 2025.

Template matching

Template matching, also known as the template matching algorithm, is a computer vision technique that finds a small reference image within a larger image by scoring similarity at every position.

Temporal convolutional network

A temporal convolutional network (TCN) is a neural network architecture using causal, dilated one-dimensional convolutions for sequence modeling, named by Lea and colleagues in 2016.

Temporal database

A temporal database, supporting bitemporal data, stores time-varying data with two time dimensions: valid time when facts were true, and transaction time when the database held them.

Temporal difference learning

Temporal difference learning is a reinforcement learning method that updates predictions of long-term value after each time step, combining Monte Carlo sampling with dynamic programming bootstrapping.

Temporal Fusion Transformer

The Temporal Fusion Transformer, or TFT, is an interpretable deep learning architecture for multi-horizon time series forecasting, introduced by Google and Oxford researchers in 2019.

Temporal graph attention network

A temporal graph attention network is a neural architecture that computes node representations on graphs whose edges and features change over time, using time-aware self-attention.

Temporal graph convolutional network

A temporal graph convolutional network (T-GCN) is a neural architecture combining graph convolutions with a GRU, proposed by Ling Zhao and colleagues in 2019 for traffic forecasting.
