Current Version Features

• Target Variable Identification: LLMs adeptly pinpoint the target variable
• Null Value Management: Choose from a variety of strategies such as mean, median, mode filling, interpolation, or introducing new categories for handling missing data, all recommended by LLMs
• Data Encoding Tactics: Automated suggestions and completions for the best encoding methods, including one-hot, integer mapping, and label encoding
• Dimensionality Reduction with PCA
• Duplicate Entity Resolution
• Data Transformation and Normalization: Utilize Box-Cox transformation and normalization techniques to improve data distribution and scalability
• Balancing Target Variable Entities: LLM-recommended methods like random over-sampling, SMOTE, and ADASYN help balance data sets, crucial for unbiased model training
• Data Set Proportion Adjustment: LLM determines the proportion of the data set (can also be adjusted manually)
• Model Selection and Training: Based on your data, LLMs recommend and initiate training with the most suitable models
• Cluster Number Recommendation: Leveraging the Elbow Rule and Silhouette Coefficient for optimal cluster numbers, with the flexibility of real-time adjustments

All processed data and models are made available for download, offering a comprehensive, user-friendly data analysis toolkit.
