Major Problems of Machine Learning Datasets: Part 1

Data quality is crucial in machine learning, and this text discusses the challenges and solutions associated with common issues in datasets, particularly focusing on missing values and categorical data. It emphasizes the importance of handling missing values through methods like dropping, imputing, or using KNN Imputer, depending on the extent of missing data. For categorical data, it highlights the need to convert them into numerical formats using techniques such as One-Hot Encoding and Label Encoding. The text also covers feature scaling to ensure consistent data influence across different value ranges and discusses methods to augment image data when dealing with limited datasets. Additionally, it touches on the conversion of data represented in ranges or textual formats into numerical values for better processing in machine learning models.
