## 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

```
