Intro

Welcome to Data Ninja. This is the "playground" site that is used to host different proof of concept (POC) works for Data Science and Machine Learning. It ain't much, but it's honest work :P



Projects

Machine Learning

A machine learning showcase where multiple machine learning techniques are used to support decision making. The showcase in situated in a automobile scenario where the machine learning techniques are used to help car manufacturer 1) to predict the car price of competitors 2) to identify a reasonable price for a new car. To reliably predict the car's price, four different machine learning models based on linear regression, decision tree regression, neural network regression, and decision forest regression. More Details

  • Using Azure Machine Learning Studio to train and host the model
  • Produce prediction of car price in real time
  • Stochastic: Accumulated probability distribution chart is used to show the chance
  • Supported by RESTful API on backend

Python Package: Data Science Utilites (DSX)

The **dsx** package contains a collection of wrapper functions to simplify common operations in data analytics tasks. The core module ds_utils (data science utilities) is designed to work with DataFrame in Pandas to simplify common tasks. More Details

  • Generate metadata of columns in a DataFrame
  • Standardize column names into iPython-friendly names
  • Expand concatenated string in a column into child table
  • Visualize DataFrame object

My PhD Research:

Incorporating Judgment Call in Decisions

This project involves the provision of an analytics platform to empower the general users to leverage the power of machine learning. One of the key value proposition is to allow the users to continuously train and develop machine learning models of their own. User's model is a reflection of a particular user´s accumulated experience, knowledge, heuristic judgment, and personal investment style, allowing the model to intelligently help the users to analyze the data in the way aligned with how the user thinks, and make sense of the situation. more details coming soon

  • Combining both technical and fundamental analysis
  • Chart stock trend with more than 100 technical indicators
  • Build personalised trading strategy
  • Bootstrap trading strategy with machine learning
  • Automatically improve trading strategy over time
  • No programming required
