#### KNN

Finding the euclidean distance that corresponds to the elbow of a graph, i.e., given graphed output: K =1 & point

![](https://raw.githubusercontent.com/edisonslightbulbs/knn-cpp/main/resources/demo.png)

##### Dependencies

###### CXX

*   [glog](https://github.com/google/glog)

*   [gflags](https://github.com/gflags/gflags)

###### Python3

*   pip3 install matplotlib

*   pip3 install pandas

*   pip3 install seaborn

##### Caveat

for `MacOS` to link glog and gflags specify the lib directories as indicated

below:

```bash

export C_INCLUDE_PATH=/usr/local/include

export CPLUS_INCLUDE_PATH=/usr/local/include

export LIBRARY_PATH=/usr/local/lib

```

##### Usage

from the project root directory

```bash

mkdir build && cd build || return

cmake ..

make

```

`CMakeLists.txt` is configured to auto-run the tartget post build (i.e., nothing else is required post build).
