Per-Unit Sequence Models01:26

Per-Unit Sequence Models

268
An ideal Y-Y transformer, grounded through neutral impedances, displays per-unit sequence networks akin to those of a single-phase ideal transformer when subjected to balanced positive- or negative-sequence currents. These currents do not produce neutral currents, and their associated voltage drops.
Zero-sequence currents, which are identical in magnitude and phase, generate a neutral current, resulting in voltage drops across the neutral impedance and the low-voltage winding. If the...

Sequence Networks of Rotating Machines

300
A Y-connected synchronous generator, grounded through a neutral impedance, is designed to produce balanced internal phase voltages with only positive-sequence components. The generator's sequence networks include a source voltage that is exclusively in the positive-sequence network. The sequence components of line-to-ground voltages at the generator terminals illustrate this configuration.
Zero-sequence current induces a voltage drop across the generator's neutral impedance and other...

Associative Learning01:27

Associative Learning

818
Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Multicompartment Models: Overview

337
Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Observational Learning01:12

Observational Learning

580
Albert Bandura's observational learning, also known as imitation or modeling, occurs when a person observes and imitates another's behavior. It is a quicker process than operant conditioning. A well-known example is the Bobo doll study, where children who saw an adult acting aggressively towards the doll were more likely to act aggressively when left alone, compared to those who observed a nonaggressive adult. Many psychologists view observational learning as a form of latent learning...

Neural Circuits

2.1K
Neural circuits and neuronal pools are two of the main structures found in the nervous system. Neural circuits are networks of neurons that work together to carry out a specific task or process. They consist of interconnected neurons and glial cells, which provide structural and metabolic support.
Neuronal pools are collections of nerve cells with similar functions and interact through chemical and electrical signals. These pools include both interneurons (the central neural circuit nodes that...

    Area of Science:

    • Computer Science
    • Artificial Intelligence
    • Machine Learning

    Background:

    • Existing recommender systems struggle to model both static and dynamic user preferences simultaneously.
    • Current methods often overlook the interplay between user/item features, context, and sequential user actions.
    • Joint modeling of context-aware user-item interactions and preference dynamics remains a significant challenge.

    Purpose of the Study:

    • To propose a novel neural time-aware recommendation network (TARN) for enhanced sequential recommendation.
    • To jointly model stationary user preferences and user preference dynamics within a temporal context.
    • To address the limitations of existing methods in capturing feature couplings and preference evolution.

    Main Methods:

    • Developed a neural time-aware recommendation network (TARN) incorporating a feature interaction network and a tailored convolutional network.
    • Utilized a feature interaction network to model pairwise couplings between user, item, and temporal context features, mitigating data sparsity.
    • Employed a convolutional network with multiple filter widths and attentive average pooling (AAP) to capture multi-fold sequential patterns and temporal action embeddings.

    Main Results:

    • TARN demonstrated superior performance compared to state-of-the-art methods on public datasets.
    • Experimental results highlighted the importance of incorporating time-aware preference dynamics.
    • The study confirmed the contribution of explicit user/item feature couplings in understanding evolving user preferences.

    Conclusions:

    • TARN effectively models both stationary and dynamic user preferences by integrating feature interactions and temporal dynamics.
    • The proposed model offers a significant advancement in sequential recommendation by capturing complex user behavior over time.
    • Involving time-aware dynamics and explicit feature couplings is crucial for accurate and interpretable user preference modeling.
