Types of Temporal Data
Temporal data can contain information about the following:
- Events: An event is a change in the state of an object at a given time. Event = Time + Object State. Examples of events are posting a tweet, sending an email, or sending a message.
Temporal information in tweets helps us understand trending topics, get the latest news updates, and analyze the sentiment of topics over time.
- Measurements: Measurements records values across time. Measurement = Time + Measures. Examples of measurements are sensor data, revenue, and stock values.
Temporal measurement information is the key feature of time-series forecasting. Also, it helps us find patterns and anomalies in a dataset with sensor data.
Another view of time can be based on how it progresses:
- Sequential: We consider time as continuous linear values here. An example of this type is a Unix timestamp.
- Cyclical: Time can be viewed as a recurrent event, where it is understood as fixed...
