DataForgeX: Prep • Plot • Evaluate • Detect

🚀 DataForgeX – Code Reduction Examples

This document shows how DataForgeX (DFX) reduces long and repetitive data science code into simple and readable one-liners.

---

1. Handling Missing Values

Without DataForgeX

import pandas as pd

for col in df.columns:
    if df[col].dtype == "object":
        df[col] = df[col].fillna(df[col].mode()[0])
    else:
        df[col] = df[col].fillna(df[col].median())

With DataForgeX

from dfx import handle_missing_values
df = handle_missing_values(df)

Code reduced: ~10 lines → 1 line

---

2. Fixing Data Types Automatically

Without DataForgeX

df["age"] = pd.to_numeric(df["age"], errors="coerce")
df["date"] = pd.to_datetime(df["date"], errors="coerce")
df["flag"] = df["flag"].map({"yes": 1, "no": 0})

With DataForgeX

from dfx import auto_fix_dtypes
df = auto_fix_dtypes(df)

---

4. Outlier Handling

Without DataForgeX

Q1 = df["chol"].quantile(0.25)
Q3 = df["chol"].quantile(0.75)
IQR = Q3 - Q1

df = df[
    (df["chol"] >= Q1 - 1.5 * IQR) &
    (df["chol"] <= Q3 + 1.5 * IQR)
]

With DataForgeX

from dfx import remove_outliers
df = remove_outliers(df)

---

5. Encoding Categorical Features

Without DataForgeX

from sklearn.preprocessing import LabelEncoder

le = LabelEncoder()
df["sex"] = le.fit_transform(df["sex"])
df = pd.get_dummies(df, columns=["cp"], drop_first=True)

With DataForgeX

from dfx import auto_encode
df = auto_encode(df)

---

6. Feature Scaling

Without DataForgeX

from sklearn.preprocessing import StandardScaler

scaler = StandardScaler()
df[cols] = scaler.fit_transform(df[cols])

With DataForgeX

from dfx import scale_data
df = scale_data(df)

---

7. Model Evaluation

Without DataForgeX

from sklearn.metrics import accuracy_score, classification_report

y_pred = model.predict(X_test)
print(accuracy_score(y_test, y_pred))
print(classification_report(y_test, y_pred))

With DataForgeX

from dfx import evaluate_classification
evaluate_classification(model, X_test, y_test)

---

8. Full Workflow Comparison

Without DataForgeX

df = fix_types(df)
df = fill_missing(df)
plot_all(df)
df = encode(df)
df = scale(df)
evaluate(model)

With DataForgeX

from dfx import auto_fix_dtypes, handle_missing_values, quick_eda
from dfx import auto_encode, scale_data, evaluate_model

df = auto_fix_dtypes(df)
df = handle_missing_values(df)
quick_eda(df)
df = auto_encode(df)
df = scale_data(df)
evaluate_model(model, X_test, y_test)

📦 Installation

Install the latest stable version from PyPI:

pip install dfx

Install with optional ML features:

pip install dfx[ml]

Install development tools:

pip install dfx[dev]

🚀 Quick Start

import pandas as pd
from dfx import (
    auto_fix_dtypes,
    handle_missing_values,
    auto_encode,
    scale_data,
    evaluate_classification
)

# Load data
df = pd.read_csv("data.csv")

# Preprocess
df = auto_fix_dtypes(df)
df = handle_missing_values(df)
df = auto_encode(df)
df = scale_data(df)

# Train model
from sklearn.ensemble import RandomForestClassifier

X = df.drop("target", axis=1)
y = df["target"]

model = RandomForestClassifier().fit(X, y)

# Evaluate
evaluate_classification(model, X, y)

🧠 Core Features

Feature	Description
Automatic dtype fixing	Detects numeric, date, and boolean columns
Missing value handling	Smart median/mode imputation
Auto encoding	Label + one-hot encoding
Scaling	Standard/robust scaling
Outlier removal	IQR-based filtering
Quick EDA	Summary + plots
Model evaluation	Metrics + reports

---

🏗️ Library Design

DataForgeX follows three design principles:

• Automation — minimal user code
• Consistency — standardized preprocessing
• Compatibility — works with pandas & sklearn

It integrates directly into existing ML pipelines without replacing them.
