Understanding Bias in Assessments and Social Service Planning
Understanding Bias in Assessments
Biases are factors and effects that can distort the validity of an internal or external evaluation. There are different types:
- Instrumentation bias: Occurs when the assessment instrument itself introduces differences between the subjects involved. For example, the language used in the test can have different levels of difficulty for some subjects and others. In open questionnaires, bias may arise from the evaluator’s interpretation of the responses.
- Non-reactive program
Pattern Recognition and Machine Learning Essentials
What is Pattern Recognition?
Pattern recognition (PR) is a process of recognizing patterns in data. The different stages of pattern recognition are:
- Preprocessing: The input data is preprocessed to remove noise and irrelevant information and to normalize it.
- Feature extraction: The relevant features are extracted from the preprocessed data. This step is crucial, as the quality of the features extracted directly impacts the algorithm’s performance.
- Feature selection: A subset of the extracted features

- The Confessor: A person who uses the opportunity provided by the group setting to present their guidelines that are irrelevant
