Feature engineering in AI refers to the process of selecting, creating, or transforming input features from raw data to improve the performance of machine learning models. It involves identifying and extracting relevant information from the data that can better represent the underlying patterns and relationships. Feature engineering can include tasks such as data preprocessing, handling missing values, scaling, encoding categorical variables, creating new features through mathematical operations, domain-specific feature selection, and more. Effective feature engineering plays a crucial role in improving the accuracy and generalization capability of AI models.
Researchers proposed a machine learning strategy to identify and classify organized retail crime (ORC) listings on a well-known online marketplace. The approach utilizes supervised learning and advanced techniques, achieving high recall scores of 0.97 on the holdout set and 0.94 on the testing dataset.
This paper presents a comprehensive study comparing the effectiveness of specialized language models and the GPT-3.5 model in detecting Sustainable Development Goals (SDGs) within text data.
