Data Classification and Labeling

Data Classification and Labeling

Data classification and labeling are key processes used to organize, process, and convert large datasets into actionable information. These concepts are extensively employed in data analytics, machine learning, and artificial intelligence.

Data Classification

Data classification involves categorizing data sets into specific groups or classes. This method determines the appropriate category for each data point and is commonly utilized within supervised learning frameworks, employing various algorithms.

Examples of algorithms used:

• Logistic regression
• Decision trees
• Support Vector Machines (SVM)
• Artificial Neural Networks

Applications:

• Email spam detection
• Customer segmentation
• Disease diagnosis
• Image recognition

Data Labeling

Data labeling refers to assigning descriptive labels or annotations to data sets based on their content. This step is essential for creating training data, particularly in supervised learning environments. Labels assist algorithms in understanding and processing data effectively during the learning phase.

Labeling methods:

• Manual labeling
• Automatic and semi-automatic labeling techniques

Applications:

• Object detection in images
• Audio analysis
• Natural language processing
• Text classification
