DeepAnalyze: Agentic Large Language Models for Autonomous Data Science
Authors: Shaolei Zhang, Ju Fan*, Meihao Fan, Guoliang Li, Xiaoyong Du
Renmin University of China, Tsinghua University
DeepAnalyze is the first agentic LLM for autonomous data science. It can autonomously complete a wide range of data-centric tasks without human intervention, supporting:
- 🛠 Entire data science pipeline: Automatically perform any data science tasks such as data preparation, analysis, modeling, visualization, and report generation.
- 🔍 Open-ended data research: Conduct deep research on diverse data sources, including structured data (Databases, CSV, Excel), semi-structured data (JSON, XML, YAML), and unstructured data (TXT, Markdown), and finally produce analyst-grade research reports.
- 📊 Fully open-source: The model, code, training data, and demo of DeepAnalyze are all open-sourced, allowing you to deploy or extend your own data analysis assistant.
🔥 News
[2026.07]: We look forward to releasing DeepPrep, a data-preparation companion to DeepAnalyze that turns raw tables into analysis-ready data.
More about DeepPrep
DeepPrep is an LLM-powered agentic system for autonomous data preparation. It constructs data-preparation pipelines through execution-grounded interaction with intermediate table states and runtime feedback, helping clean, transform, and standardize raw data before downstream analysis.

[2026.06.15]: We release CoDA-Bench, a benchmark for evaluating whether code agents can handle data-intensive analytical tasks, closely aligned with DeepAnalyze's target scenarios.
More about CoDA-Bench
CoDA-Bench evaluates agents in a Linux sandbox with hundreds of data files. Given a natural-language question, an agent must discover relevant data, write executable code, and produce the final answer. It provides a benchmark setting for the same type of data discovery and code-execution challenges targeted by DeepAnalyze.

# Comprehensive Analysis of Student Enrollment Patterns and Institutional Transfers
## Introduction and Research Context
The analysis of student enrollment patterns represents a critical area of educational research with significant implications for institutional planning, resource allocation, and student support services. This comprehensive study examines a comprehensive dataset encompassing 1,194 enrollment records across six educational institutions, merged with supplementary demographic, financial, and employment status data. The research employs advanced analytical techniques including network analysis, predictive modeling, and temporal pattern recognition to uncover both macro-level institutional trends and micro-level student mobility patterns. The dataset's longitudinal nature, spanning fifteen months of enrollment records, provides unique insights into the complex dynamics of student pathways through higher education systems.
Our methodological approach combines quantitative analysis of enrollment durations, transfer probabilities, and financial indicators with qualitative ...
The research contributes to the growing body of literature on student mobility by providing empirical evidence of institutional transfer networks and their relationship to student outcomes...
