Model Building


  • Model – A file that has been trained to recognize certain types of patterns.
  • Algorithm – a set of clearly defined instructions a computer uses to solve a problem such as learning and prediction
  • Hyperparameters – the variables that are used to configure an algorithm for learning and prediction
  • Model Tuning – changing hyperparameters to improve the performance of a model

Types of Models

  • Classification – when the target/output is discrete or categorical e.g Jacket or no Jacket, good or bad etc.
  • Regression – when the target is continuous e.g temperature – 15.8,19.6,12.0 or salaries 100K, 60K, 80K etc.

Model vs. Algorithm

  • An algorithm is the set of instructions a computer follows to solve a problem.
  • A model is the set of assumptions formed when an algorithm that takes some values as input and produces some values as output.

Building a Model

  • Use different algorithms to train a model on the dataset
  • Test the model’s performance using the testing data
  • Improvement performance of the model by tuning the hyperparameters

Now learn how to evaluate model performance.
