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.
