Cluster Sampling Method01:20

Cluster Sampling Method

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

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...
Classification of Systems-I01:26

Classification of Systems-I

Linearity is a system property characterized by a direct input-output relationship, combining homogeneity and additivity.
Homogeneity dictates that if an input x(t) is multiplied by a constant c, the output y(t) is multiplied by the same constant. Mathematically, this is expressed as:
Classification of Systems-II01:31

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,
Survival Tree01:19

Survival Tree

Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

  • To address scenarios with both complete and incomplete class assignments of labeled patterns.

Main Methods:

  • Modified FUZZY ISODATA algorithm with an additive objective function component for labeled data.
  • Development of algorithms for two distinct learning scenarios: complete and incomplete class assignments.
  • Validation using numerical examples with both synthetic and real-world software engineering datasets.

Main Results:

  • Demonstrated effectiveness of the proposed algorithms in fuzzy clustering with partial supervision.
  • Successful integration of labeled patterns improved clustering performance compared to purely unsupervised methods.
  • Algorithms showed robustness across different data types and assignment completeness.

Conclusions:

  • Partial supervision is a viable and effective strategy for enhancing fuzzy clustering.
  • The proposed additive incorporation of labeled data into FUZZY ISODATA offers a flexible approach.
  • The methods are applicable to real-world problems, particularly in software engineering data analysis.
