Description

Data is in HDF5 format (with LZF compression). For specifics and details, please see https://github.com/GilesStrong/mode_diffprog_22_challenge

The training file contains two datasets:

  • `'x0'`: a set of voxelwise X0 predictions (float32)
  • `'targs'`: a set of voxelwise classes (int):
  • 0 = soil
  • 1 = wall

 

The format of the datasets is a rank-4 array, with dimensions corresponding to (samples, z position, x position, y position).

All passive volumes are of the same size: 10x10x10 m, with cubic voxels of size 1x1x1 m, i.e. every passive volume contains 1000 voxels.

The arrays are ordered such that zeroth z layer is the bottom layer of the passive volume, and the ninth layer is the top layer.

It can be read using e.g. the code below:

 

with h5py.File('train.h5', 'r') as f:

  inputs = h5['x0'][()]

  targets = h5['targs'][()]

The test file only contains the X0 inputs:

with h5py.File('test.h5', 'r') as h5:

  inputs = h5['x0'][()]

The private testing sample also contains targets. The private and public splits can be recovered using:

from sklearn.model_selection import train_test_split

pub, pri = train_test_split(targets, test_size=25000, random_state=3452, shuffle=True)
