Cluster Sampling Method01:20

Cluster Sampling Method

11.6K
Appropriate sampling methods ensure that samples are drawn without bias and accurately represent the population. Because measuring the entire population in a study is not practical, researchers use samples to represent the population of interest.
To choose a cluster sample, divide the population into clusters (groups) and then randomly select some of the clusters. All the members from these clusters are in the cluster sample. For example, if you randomly sample four departments from your...

Aggregates Classification01:29

Aggregates Classification

305
Aggregate classification is generally based on its size, petrographic characteristics, weight, and source. Size classification ranges from coarse to fine aggregates, defined by the size of the particles. Coarse aggregates are particles that do not pass through ASTM sieve No. 4, and aggregates that pass through the sieve are fine aggregates.
Petrographic classification groups aggregates based on common mineralogical characteristics. Some of the common mineral groups found in aggregates are...

In- and Out-Groups

38.9K
People all belong to a gender, race, age, and social economic group. These groups provide a powerful source of our identity and self-esteem (Tajfel & Turner, 1979) and serve as our in-groups. An in-group is a group that we identify with or see ourselves as belonging to.

Self-Discrepancy Theory02:45

Self-Discrepancy Theory

18.3K
One influential perspective on what motivates people's behavior is detailed in Tory Higgin's self-discrepancy theory (Higgins, 1987). He proposed that people hold disagreeing internal representations of themselves that lead to different emotional states.

Group Polarization01:01

Group Polarization

34.2K
Group polarization is the strengthening of an original group attitude following the discussion of views within a group (Teger & Pruitt, 1967). That is, if a group initially favors a viewpoint, after discussion the group consensus is likely a stronger endorsement of the viewpoint. Conversely, if the group was initially opposed to a viewpoint, group discussion would likely lead to stronger opposition.

Stereotype Content Model02:16

Stereotype Content Model

14.0K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

    Area of Science:

    • Computer Science
    • Artificial Intelligence
    • Machine Learning

    Background:

    • Self-expressiveness-based subspace clustering relies heavily on the self-expressive coefficient.
    • Enhancing the precision of this coefficient is critical for accurate clustering results.

    Purpose of the Study:

    • To propose a novel deep subspace clustering method, GRESS, for improved self-expressive coefficient precision.
    • To integrate clustering information and higher-order relationships into the coefficient matrix.

    Main Methods:

    • Developed a deep contrastive subspace clustering module for simultaneous learning of coefficients and cluster representations.
    • Introduced a grouping belief-based affinity refinement module to leverage higher-order relationships.
    • Implemented noisy similarity suppression and similarity increment regularization.

    Main Results:

    • Achieved noiseless self-expressive and cluster-based similarities.
    • Effectively uncovered higher-order relationships within the similarity matrix.
    • Demonstrated superior performance over state-of-the-art methods on benchmark datasets.

    Conclusions:

    • GRESS significantly enhances subspace clustering accuracy by refining self-expressive coefficients.
    • The integration of grouping belief and contrastive learning offers a robust approach to uncover complex data relationships.
