CorrelAid Machine Learning Winter School
Welcome to the CorrelAid ML Winter School!
The problem we want to solve is to classify trees in Roosevelt National Forest.
Please make sure you have a modern Python 3 installation. We recommend the Python distribution Miniconda that is available for all OS.
The easiest way to get started is with a clean virtual environment. You can do so by running the following commands, assuming that you have installed Miniconda or Anaconda.
$ conda create -n winter-school python=3.9 $ conda activate winter-school (winter-school) $ pip install -r requirements.txt (winter-school) $ python -m ipykernel install --user --name winter-school --display-name "Python 3.9 (winter-school)"
The first command will create a new environment with Python 3.9. To use this environment, you call
conda activate <name> with the name of the environment as second step. Once activated, you can install packages as usual with the
pip package manager. You will install all listed requirements from the provided
requirements.txt as a third step. Finally, to actually make your new environment available as kernel within a Jupyter notebook, you need to run
ipykernel install, which is the fourth command.
Once the setup is complete, you can run any notebook by calling
(winter-school) $ <jupyter-lab|jupyter notebook>
jupyter lab is opening your browser with a local version of JupyterLab, which is a web-based interactive development environment that is somewhat more powerful and more modern than the older Jupyter Notebook. Both work fine, so you can choose the tool that is more to your liking. We recommend to go with Jupyter Lab as it provides a file browser, among other improvements.
The dataset contains tree observations from four areas of the Roosevelt National Forest in Colorado. All observations are cartographic variables (no remote sensing) from 30 meter x 30 meter sections of forest. There are over half a million measurements total!
The dataset includes information on tree type, shadow coverage, distance to nearby landmarks (roads etcetera), soil type, and local topography.
Note: We provide the data set as it can be downloaded from kaggle and not in its original form from the UCI repository.
Given is the attribute name, attribute type, the measurement unit and a brief description. The forest cover type is the classification problem. The order of this listing corresponds to the order of numerals along the rows of the database.
Name / Data Type / Measurement / Description
- Elevation / quantitative /meters / Elevation in meters
- Aspect / quantitative / azimuth / Aspect in degrees azimuth
- Slope / quantitative / degrees / Slope in degrees
- Horizontal_Distance_To_Hydrology / quantitative / meters / Horz Dist to nearest surface water features
- Vertical_Distance_To_Hydrology / quantitative / meters / Vert Dist to nearest surface water features
- Horizontal_Distance_To_Roadways / quantitative / meters / Horz Dist to nearest roadway
- Hillshade_9am / quantitative / 0 to 255 index / Hillshade index at 9am, summer solstice
- Hillshade_Noon / quantitative / 0 to 255 index / Hillshade index at noon, summer soltice
- Hillshade_3pm / quantitative / 0 to 255 index / Hillshade index at 3pm, summer solstice
- Horizontal_Distance_To_Fire_Points / quantitative / meters / Horz Dist to nearest wildfire ignition points
- Wilderness_Area (4 binary columns) / qualitative / 0 (absence) or 1 (presence) / Wilderness area designation
- Soil_Type (40 binary columns) / qualitative / 0 (absence) or 1 (presence) / Soil Type designation
- Cover_Type (7 types) / integer / 1 to 7 / Forest Cover Type designation
