dataset
posted on 2019-05-03, 01:18 authored by Toru TamakiToru Tamaki, Ken YodaThis is the dataset for the competition ABC2018. The competition website is:
https://competitions.codalab.org/competitions/16283
File
A zip file contains all the training and test trajectories, and a ground truth label file for the training set.
When you unzip the dataset, you find
./test/***.csv
./train/***.csv
./train_labels.csv
where *** is the trajectory number (000, 001, ..., 630 for train, 000, 001, ..., 274 for test).
Task
Classifying GPS trajectories of birds into male or female
Trajectory file format
A single CSV file (000.csv, 001.csv, ...) contains a trajectory of a trip, and each line represents the information of a GPS location of a shearwater. In addition to longitude and latitude, some other information is provided; elapsed time and local clock time, solar azimuth and elevation angles.
- float: longitude
- float: latitude
- float: sun azimuth [degree] clockwise from the North
- float: sun elevation [degree] upward from the horizon
- int: (1) daytime (between sunrise and sunset), or (0) nighttime
- int: elapsed time [second] after starting the trip
- clock: local time (hh:mm:ss)
- int: days (starts from 0, and increments by 1 when the local time passes 23:59:59)
Float values are of the format %.5f, and fields are separated by a single comma.
Here is an example:
=================
139.29220,38.56632,76.42170,-4.45122,0,0,04:54:03,0
139.29300,38.56763,76.58196,-4.25726,0,60,04:55:03,0
139.29400,38.57053,76.73674,-4.06880,0,118,04:56:01,0
139.29620,38.57563,76.89729,-3.87201,0,178,04:57:01,0
...
=================
- Different trajectories have different number of GPS locations.
- The time interval between successive two GPS locations is approximately one minute (60 seconds) when GPS works well, otherwise interval may vary from one to several minutes, even hours and days.
- Trajectories in the training and test sets are in the same format.
- Ground truth labels for the training set are given in a separate file.
Labels: gender, or male/female
A single txt file of ground truth labels of the training set is provided. Each line has the label of the corresponding training trajectory; that is, line 0 is the label of the training trajectory file 000.csv.
Label is binary (character):
- male: 0
- female: 1
