kaizenstat 0.2.4

Zero-friction AutoML + Data Cleaning Toolkit

🚀 KaizenStat

KaizenStat is a zero-friction, production-grade AutoML, automated data cleaning, and model explanation engine. It allows you to audit datasets, repair data issues, benchmark models with hardware-aware optimization, export standalone pipeline code, and host web-based dashboards—all with a single command or Python import.

---

🎯 Core Philosophy

• Zero-Friction AutoML: No complex configuration files. Pass your dataset, name your target, and KaizenStat does the rest.
• Production Crash-Proofing: Automatically handles messy real-world data issues: high-cardinality ID columns, datetime parsing, missing inputs, class imbalance, and label encoding.
• Explainable AI: Breaks open the "black box" by generating standalone, human-readable Python training code reproducing the best-found pipeline.
• Hybrid Interface: 100% parity between CLI and Python API.

⚔️ CLI & Python API Feature Matrix

KaizenStat is designed around a single unified vocabulary. Every CLI command has a direct, equivalent function in the Python SDK.

Command	Python API	Purpose
kz audit	KaizenStat.audit()	🔍 Runs a diagnostic sweep (missing values, duplicates, imbalance, dead features).
kz heal	KaizenStat.heal()	🩹 Clean, impute, parse datetimes, drop IDs, and encode string labels.
kz benchmark	KaizenStat.benchmark()	🚀 Automatically trains, optimizes, and ranks model pipelines.
kz auto	KaizenStat.auto()	⚡ Orchestrates the entire pipeline in sequence (Audit ➔ Heal ➔ Benchmark).
kz explain	KaizenStat.explain()	💬 Generates plain-English diagnostic summaries and model recommendations.
kz codegen	KaizenStat.codegen()	📝 Generates standalone, dependency-free Python code for the best model.
kz export-model	KaizenStat.save_model()	💾 Trains the top pipeline and saves it directly to a .joblib binary.
kz report	KaizenStat.report()	📊 Generates a beautiful, interactive HTML profiling report with Chart.js.
kz serve	KaizenStat.serve()	🌐 Launches a local web dashboard to explore the data and run predictions.
-	KaizenStat.analyze()	🧠 Executes auto-intelligence analysis over dataset context using LLM reasoning.
-	KaizenStat.ask()	🤖 Answers complex developer queries about accuracy, data quality, or anomalies.
-	KaizenStat.ask_followup()	🔁 Maintains multi-turn conversation memory with the data reasoning engine.

💡 Quick Start Guide

1. Python SDK Usage

from kaizenstat import KaizenStat
import pandas as pd

# Load your dataset
df = pd.read_csv("dataset.csv")

# 1. Diagnose issues
findings = KaizenStat.audit(df, target="target_column")

# 2. Automatically heal dirty data
clean_df = KaizenStat.heal(df, target="target_column")

# 3. Benchmark models with cross-validation
leaderboard = KaizenStat.benchmark(clean_df, target="target_column")

# 4. Generate standalone code for reproduction
KaizenStat.codegen("dataset.csv", target="target_column", output_path="reproduce.py")

# 5. Dual-Mode Conversational AI (OpenRouter powered)
# Runs automated structured AI analysis
analysis = KaizenStat.analyze(df, target="target_column")

# Ask custom developer queries about data or pipeline
KaizenStat.ask("Why is model accuracy lower or what are the dataset flaws?")

# Multi-turn conversation with memory context
KaizenStat.ask_followup("What should I do to handle the missing values or high cardinality?")

2. Command Line Interface (CLI)

# Get quick help and list commands
kz --help

# Run the full pipeline in one command
kz auto dataset.csv --target target_column

# Repair a dataset and save the clean file
kz heal dataset.csv --target target_column -o cleaned_dataset.csv

# Launch a local Streamlit app to preview and test model performance
kz serve dataset.csv --target target_column --port 8501

🧠 Behind the Scenes: Core Engines

1. Hardware-Aware Execution

KaizenStat automatically checks your environment using detect_device(). It leverages CUDA on Nvidia GPUs and MPS on Apple Silicon (M1/M2/M3 Mac) to accelerate training when optional dependencies (like xgboost) are installed.

2. Smart Model Selection

The benchmarking engine adjusts its logic dynamically based on the dataset properties:

• Large Datasets (>100k rows): Excludes slow estimators (like Gradient Boosting) on standard CPU hosts to prevent compute lockups.
• High-Cardinality Categoricals: Optimizes feature preprocessors and prioritizes tree-based models (Random Forests, Gradient Boosting, XGBoost).
• Float Targets: Detects values with a continuous numeric profile and switches the entire pipeline to regression mode automatically.

3. Automatic Imbalance Correction

During data healing, KaizenStat computes target ratios. If target class distribution has a skew larger than 65% / 35%, it adjusts model parameters dynamically (e.g. setting class_weight="balanced" in scikit-learn estimators).
