Irregularities
Irregularities refer to any deviation or anomaly in a dataset that does not conform to the expected pattern or behavior. These can be caused by various factors such as measurement errors, data entry mistakes, outliers, or even intentional manipulation of data. In data science, identifying and dealing with irregularities is crucial for ensuring the accuracy and reliability of the analysis results. This involves performing data cleaning and preprocessing techniques such as outlier detection, missing value imputation, and data normalization. Additionally, statistical methods such as hypothesis testing and regression analysis can be used to identify and quantify the impact of irregularities on the analysis. In machine learning, irregularities can affect the performance of the models and lead to overfitting or underfitting. Therefore, techniques such as regularization and cross-validation are used to mitigate the impact of irregularities on the model performance.
