Overview of TaxoExpan
TaxoExpan is a unique self-supervised taxonomy expansion framework that is designed to automatically generate pairs of query concepts and anchor concepts from the existing taxonomy as training data. This framework is incredibly useful as it can learn to predict whether a query concept is the direct hyponym of an anchor concept. TaxoExpan features two primary components: a position-enhanced graph neural network and a noise-robust training objective.
The primary goal of Tax
What is TayPO?
TayPO, short for Taylor Expansion Policy Optimization, is a set of algorithms used for policy optimization. The algorithms use the k-th order Taylor expansion method, which generalizes previous methods such as TRPO or trust-region policy optimization. The method unites concepts from both trust-region policy optimization and off-policy corrections.
Understanding Taylor Expansion
Taylor expansion is a mathematical method used to approximate a function $f(x)$ as a sum of terms ba
Introduction to TD-Gammon
TD-Gammon is a program that uses a combination of artificial intelligence and machine learning to play Backgammon. Created in the early 1990s, TD-Gammon was the first program to showcase a neural network that could learn to play a game through self-play without human intervention.
TD-Gammon was born out of a collaboration between the computer scientists Gerald Tesauro and Jonathan Schaeffer. The goal was to use machine learning techniques to create a program that coul
TD Lambda is an advanced algorithm used in reinforcement learning. It's an extension of other reinforcement learning algorithms, but it includes something called an eligibility trace.
What is an Eligibility Trace?
When using the TD Lambda algorithm, a vector called the eligibility trace keeps track of recent state valuations. The eligibility trace vector starts at zero and is incremented on each time step by the value gradient. Then it fades away over time by a particular factor. This eligibi
Are you interested in machine learning and generative sequence models? Then you might want to learn about TD-VAE! TD-VAE stands for Temporal Difference VAE, and it can learn to generate future states with explicit beliefs. Let's explore TD-VAE and learn more about how it works.
What is TD-VAE?
TD-VAE is a generative sequence model that can predict future states. It learns to represent the beliefs about several steps ahead, without single-step transitions. Its name comes from temporal differen
Overview of Teacher-Tutor-Student Knowledge Distillation
Teacher-Tutor-Student Knowledge Distillation is a method used in image virtual try-on models. It helps adjust and improve fake images produced by parser-based methods using the appearance flows of real images. Essentially, this method allows the imitation of real person images to produce high-quality results in the virtual try-on process.

Temporal Action Localization is a technique used to detect and locate specific activities in a video. This technique is used in several fields such as security and entertainment. By analyzing video streams and proposing beginning and end timestamps, the technique can help identify actions of interest.
What is Temporal Action Localization?
Temporal Action Localization is the process of detecting an action in a video stream and identifying the location and duration of the action. The technique
Temporal Activation Regularization: A Method for Improving RNN Performance
Recurrent Neural Networks (RNNs) are a type of artificial neural network commonly used for sequential data processing such as natural language processing and speech recognition. However, training RNNs can be challenging due to their tendency to suffer from vanishing or exploding gradients, which can result in unstable and ineffective learning. To address this issue, researchers have developed various regularization techn
TAM: A Lightweight Method for Capturing Complex Temporal Relationships in Videos
If you're familiar with computer vision, you may already know that temporal modeling in videos is essential for recognizing complex actions, detecting anomalies, and tracking objects from frame to frame. However, doing so accurately and efficiently can be challenging. This is where Temporal Adaptive Modules (TAM) come in.
TAM is a lightweight method designed to capture complex temporal relationships efficiently an
What is Temporal Attention?
Temporal attention is a mechanism in our brain where we select and pay attention to things happening at specific moments in time. It's a way for us to process information efficiently and navigate through our environment with ease. Technically speaking, it's the ability to selectively process information at specific points in time.
Temporal attention can be seen as an important component of both visual and audio information processing. For example, when watching a vi
Temporal Distribution Characterization: Understanding Time Series Data
Temporal Distribution Characterization, or TDC, is a powerful module in the AdaRNN architecture that characterizes the distributional information in a time series. Time series data is any data that is collected over a period of time, such as stock prices, weather data, or medical data. Analyzing time series data can be difficult because the data changes over time, and the traditional statistical models may not be suitable fo
Welcome to the world of Temporal Distribution Matching (TDM)!
What is TDM?
Temporal Distribution Matching is a method for matching the distributions of the discovered periods to build a time series prediction model. It is used in the AdaRNN architecture, which is a type of recurrent neural network model.
Why use TDM?
The TDM module is designed to learn the common knowledge shared by different periods via matching their distributions. This allows the learned model to generalize well on unse
What is TGN?
Temporal Graph Network, or TGN for short, is a type of framework used in deep learning on dynamic graphs. These graphs are represented as sequences of timed events. So, TGNs are used to analyze graph data where the information changes over time. This makes it different from other types of deep learning frameworks that focus only on static graphs.
How Does TGN Work?
The memory or state of the Temporal Graph Network is represented by a vector $\mathbf{s}_i(t)$ for each node $i$ th
Temporal information extraction is the process of identifying and determining the temporal relationships between chunks of text. These chunks could be temporal expressions, events, or auxiliary signals that help understand the context. Temporal expressions are dates, times, and durations. The relationship between these expressions is critical in finding meaningful insights in the data.

Temporal information extraction is the process of extracting tempo
What is TPN and How Does It Work?
Temporal Pyramid Network, or TPN, is a module used in action recognition that operates at the feature level. It can be easily integrated into backbone networks, which are used to extract hierarchical features from an input video.
TPN takes these features and creates a pyramid-level hierarchy. This structure allows the system to recognize actions occurring at various speeds, or tempos. The feature hierarchy is itself made up of several components, including Bac
Temporal Relation Classification is a task with the purpose of identifying the time relationship between two temporal entities, such as traditional events and temporal expressions. The classification is based on thirteen relation types from James Allen's influential work called "Maintaining Knowledge about Temporal Intervals."
