# linreg
Building my own C++ library for the Linear Regression
## Latest Feature
- Find a linear regression equation
- Fix invalid track value
- Update error handling (data size, invalid value)
## Example
```c++
// main.cpp
#include
#include
#include
int main()
{
linreg::model model;
linreg::parameter param;
std::vector x = {1, 2, 3, 4, 5, 6, 7, 8, 9, 10};
std::vector y = {4, 5, 6, 7, 8, 9, 10, 11, 12, 13};
double alpha = 0.01; // Learning rate
int epochs = 3333;
int track = 1; // Type 1 : track value
param = model.fit(x, y, param, alpha, epochs, track);
std::cout << "y = " << param.w << "x + " << param.b << std::endl;
std::cout << "loss: " << param.mse << std::endl;
return 0;
}
```
## Run
Run the following command in the Developer CMD for VS
```cmd
cd build
```
```cmd
cmake ..
```
```cmd
cmake --build .
```
```cmd
cd Debug
```
```cmd
main
```
or
```cmd
g++ -I lib/include -c lib/src/mse.cpp -o build/obj/mse.o
g++ -I lib/include -c lib/src/gradient_descent.cpp -o build/obj/gradient_descent.o
g++ -I lib/include -c lib/src/linreg.cpp -o build/obj/linreg.o
g++ -I lib/include -o build/program/program main.cpp build/obj/mse.o build/obj/gradient_descent.o build/obj/linreg.o
```
