DeepCF: A Deep Feature Learning-Based Car-Following Model Using Online Ride-Hailing Trajectory Data

Algorithm 2. Decision database retrieval algorithm s_su.

Input:

Decision library ; Searched feature vector

Output:

The fourth feature of the most similar variable

Begin

1. Standardized and

 Set the threshold

2. Brush the database according to the feature vector x

3. Pick out the vector set within the threshold

4. for i in

5. use the decision index algorithm to calculate the distance between x and i,

6. Sort the vector in according to

7. Output the fourth feature of the closest vector

End
