Dexter Toolkit

Data Experimentation and Tinkering Kit

A comprehensive Python toolkit for data science, machine learning, optimization, simulation, and visualization experiments.

Overview

Dexter is a modular toolkit designed for rapid prototyping and experimentation in data science and related fields. It provides a collection of specialized modules for different aspects of data analysis, machine learning, optimization, and visualization.

🚀 Quick Start

Installation

# Clone the repository
git clone https://github.com/DenizK00/Dexter.git
cd Dexter

# Install in development mode
make install-dev

# Or install manually
python install_dev.py

Basic Usage

import dexter

# Machine Learning
from dexter import pick_classifier
import pandas as pd

df = pd.read_csv('your_data.csv')
best_model = pick_classifier(df, target='target_column')

# Optimization
from dexter import Problem

objective = "min 2*x + 3*y"
constraints = ["x + y >= 10", "x >= 0", "y >= 0"]
problem = Problem(objective, constraints)
solution = problem.solve()

# Statistics
from dexter import Normal, Uniform

normal_dist = Normal(mean=0, var=1)
rv = normal_dist.draw()

# Simulation
from dexter import SimManager
import simpy

env = simpy.Environment()
sim = SimManager(env)
sim.run(until=100)
