A horizontal line on a distance-time graph close distance-time graphA graph with distance travelled plotted on the vertical axis against time taken on the horizontal axis. shows that the object is ...

The steeper the line, the greater the increase in speed. The area under the graph = the distance travelled. This is a speed-time graph for a car moving between two sets of traffic lights.

Abstract: We propose a novel method for learning time-varying graphs from time-series data by leveraging techniques from directed acyclic graph (DAG) learning. The unknown graphs are parameterized ...
