Machine-Learning

This is a story related to machine learning and all data science skill.

Keys of Machine Learning

  • Steps for building a Machine Learning

    1.Asking Questions

    2.Data Preparation(Preprocessing:Categorial feature,missing value and standardization;feature selection)

    3.Building Models with Different Hyperparameters

    4.Test and Evaluate Models

  • Machine Learning Models

    1.Objective function (loss function)

    2.Approximation function (to approximate the true function)

    3.Optimization Method (to optimize the objective function)
