Social Proof

Social proof is a form of persuasion based on comparison and conformity. People compare their behavior and actions to what others are doing and will change to conform to do what their peers do.

Classification of Systems-II

Classification of Systems-II

Continuous-time systems have continuous input and output signals, with time measured continuously. These systems are generally defined by differential or algebraic equations. For instance, in an RC circuit, the relationship between input and output voltage is expressed through a differential equation derived from Ohm's law and the capacitor relation,

Confidence Coefficient

Confidence Coefficient

The confidence coefficient is also known as the confidence level or degree of confidence. It is the percent expression for the probability, 1-α, that the confidence interval contains the true population parameter assuming that the confidence interval is obtained after sufficient unbiased sampling; for example, if the CL = 90%, then in 90 out of 100 samples the interval estimate will enclose the true population parameter. Here α is the area under the curve, distributed equally under...

Social Facilitation

Social Facilitation

Not all intergroup interactions lead to negative outcomes. Sometimes, being in a group situation can improve performance. Social facilitation occurs when an individual performs better when an audience is watching than when the individual performs the behavior alone. This typically occurs when people are performing a task for which they are skilled.

Aggregates Classification

Aggregates Classification

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...

Social Exchange Theory

Social Exchange Theory

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Background:

Social network sentiment classification is crucial for opinion monitoring and market analysis.
Ensemble methods excel in sentiment classification due to classifier diversity.
Existing methods like boosting and voting have limitations in computation time or error utilization.

Purpose of the Study:

To propose a novel two-stage voting boosting (2SVB) concurrent ensemble learning method.
To decrease computation time while optimizing the utilization of erroneous data.
To enhance overall ensemble performance in social network sentiment classification.

Main Methods:

A two-stage concurrent ensemble framework combining voting and boosting.
Stage-1: 3-fold cross-segmentation training.
Stage-2: Training on augmented datasets with stage-1 misclassified data, using five pre-trained deep learning models.

Main Results:

The proposed 2SVB method achieved an F1 score of 0.8942 on a coronavirus tweet sentiment dataset.
Outperformed other comparable ensemble methods in sentiment classification.
Demonstrated reduced computation time and improved accuracy through optimized error utilization.

Conclusions:

The 2SVB method effectively balances computation time and performance in sentiment classification.
The two-stage training approach significantly enhances the utilization of erroneous data.
This novel ensemble method offers a superior solution for social network sentiment analysis.
