Study Notes

  • Data Science is the process of using human and computer intelligence to analyze data.
  • There are many different types of data science, including classification, regression, clustering, and anomaly detection.
  • The goal of data science is to make predictions about future events or trends, using models that have been learned from past data.
  • Data exploration is the first step in data science, and it involves looking at the data to find patterns.
  • Model evaluation is the process of testing the accuracy of models.
  • Classification is a task that is used to group data points into categories.
  • Decision trees, neural networks, Bayesian models, and induction rules are all types of models that can be used for prediction.
  • Assignment of voters into known buckets is an example of a task that is used in regression.
  • Linear regression is used to predict the numeric target label of a data point, and logistic regression is used to predict the probability of an event happening.
  • Anomaly detection is a task that is used to determine if a data point is an outlier compared to other data points.
  • Time series forecasting is a type of prediction that is used to predict future events.
  • Feature selection is a process that is used to find the best features for a given task.
