Machine Learning Applications

  1. Stock Price Predictions

If finance excites you, then predicting stock prices using machine learning might be interesting for you.  In these kinds of projects, you have different types of data to choose from such as prices, global macroeconomic indicators, fundamentals, volatility indices, and much more. These data can be very granular. Typically, financial markets have short feedback cycles, so you can validate your predictions on new data.

Points to Note

  • You can download stock market machine learning datasets from Quandl.com or Quantopian.com.
  • If you are a beginner, you can limit the project to predict six-month price movements based on your quarterly organisation report.

2. Disease Prediction

With machine learning on the rise, the medical science industry is undergoing drastic changes. Based in Seattle, Washington, KenSci is a healthtech company that employs machine learning to predict illness to help physicians intervene earlier. They predict health risk by identifying patterns and surfacing high-risk markers and model disease progression and more. The company is harnessing AI and machine learning for improving health records and workflow.

What do they do?

  • KenSci collects the health system’s data from sources like wearables, EMR records, medical devices, Claims, and ERP systems.
  • Using machine learning, they carry out data integration, format conversion, data scrubbing, feature engineering, censoring and more.
