<|assistant|>: Sure! To add polynomial features up to degree ( n ), you'll need an additional function that transforms your input matrix ( X ) into one containing polynomial features.
Here’s how you can modify your class:
python
from sklearn.preprocessing import PolynomialFeatures
class LinearRegression():
    def __init__(self):
        self.coef_ = None
        self.intercept_ = None
    def _add_polynomial_features(self, X_train, degree):
        poly = PolynomialFeatures(degree)
        return poly.fit_transform(X_train)
    def fit(self, X_train, y_train, degree=1):
        assert X_train.shape[0] == y_train.shape[0], 
            'The size of X_train must be equal to the size of y_train.'
        assert len(X_train.shape) ==2,
            'X_train must be a matrix.'
        # Add polynomial features if degree > 1
        if degree > 1:
            X_train = self._add_polynomial_features(X_train, degree)
        self.coef_ = np.linalg.inv(X_train.T.dot(X_train)).dot(X_train.T).dot(y_train)
Now you can specify the degree when calling `fit`:
python
model = LinearRegression()
model.fit(X_train, y_train, degree=2)
<|end|>
<|user|>: Can we add regularization too? Ridge or Lasso?<|end|>
<|assistant|>: Sure! Let’s integrate Ridge regularization into your code first since it involves simpler modifications compared to Lasso.
Here’s how you can modify your `fit` method:
python
class LinearRegression():
    def __init__(self):
        self.coef_ = None
        self.intercept_ = None
    def _add_polynomial_features(self, X_train, degree):
        poly = PolynomialFeatures(degree)
        return poly.fit_transform(X_train)
    def fit(self, X_train, y_train, degree=1, alpha=0):
        assert X_train.shape[0] == y_train.shape[0], 
            'The size of X_train must be equal to the size of y_train.'
        assert len(X_train.shape) ==2,
            'X_train must be a matrix.'
        # Add polynomial features if degree >1 
        if degree >1:
            X_train=self._add_polynomial_features(X_train,degree)
        # Add Ridge regularization term alpha*I where I is identity matrix.
        I = np.eye(X_train.shape[1])
        I[:-1,:-1] = np.zeros((X_train.shape[1]-1,X_train.shape[1]-1)) # Exclude bias term from regularization
        self.coef_ = np.linalg.inv(X_train.T.dot(X_train) + alpha * I).dot(X_train.T).dot(y_train)
You can now specify `alpha` when calling `fit`:
python
model = LinearRegression()
model.fit(X_train, y_train, degree=2, alpha=0.5)
<|end|>
<|user|>: What if I want custom loss function? Can we add that?<|end|>
<|assistant|>: Absolutely! To allow custom loss functions during fitting, you’ll need some modifications:
Firstly you’ll need an additional parameter `loss_function` in your `fit` method:
python
class LinearRegression():
    def __init__(self):
        self.coef_ = None
        self.intercept_ = None
    def _add_polynomial_features(self,X_train,degree):
        poly=PolynomialFeatures(degree)
        return poly.fit_transform(X)
    def fit(self,X_train,y_true,degree=1,alpha=0.,loss_function=None):
        assert X_tain.shape==y_true.shape,'The size of X_tain must be equal to y_true'
        assert len(X_tain.shape)==2,'X_tain must be a matrix.'
        if degree >1:
            X_tain=self._add_polynomial_features(X_tain,degree)
        I=np.eye(X_tain.shape[-1])
        I[:-1,:-1]=np.zeros((X_tain.shape[-1]-1,X_tain.shape[-1]-1))
        coef_initial=np.linalg.inv(X_tain.T.dot(X_tain)+alpha*I).dot(X_tain.T).dot(y_true)
        if loss_function:
            self.coef_=self._optimize_with_custom_loss(coef_initial,X_tain,y_true)
        else:
            self.coef_=coef_initial
    
    def _optimize_with_custom_loss(self,start_coef,X,y):
       from scipy.optimize import minimize
       res=minimize(fun=lambda coef:self.loss_function(coef,X,y),x0=start_coef)
       return res.x
    
    def set_loss_function(self,function):
       self.loss_function=function
# Example usage:
def custom_loss(coef,X,y):
   predictions=X.dot(coef)
   return np.sum(np.abs(predictions-y)) # example LAD loss
model=LinearRegression()
model.set_loss_function(custom_loss)
model.fit(X_tain,y_true,degree=2,alpha=0.,loss_function=True)
This way you can define any custom loss function outside your class definition like `custom_loss`, set it using `set_loss_function`, then call `fit`.

In this paper we show that existing empirical results based on cross-country correlations between physical capital accumulation rates or savings rates do not necessarily imply any connection between these variables at an aggregate level or at industry level within countries because there are forces at work which link these variables at microeconomic level within industries.
Our theoretical model is based on Kimura et al.’s “Intra-Industry” model [Kimura et al.,1999]. Their model is based on an extension of Kiyotaki’s [Kiyotaki & Wright (1989)] model where money is introduced as medium of exchange via double coincidence problem associated with barter exchange [Kiyotaki & Wright (1993)]. In Kimura et al.’s model there exist two types of agents - borrowers who produce final goods using only labor but cannot hold physical capital because they do not have enough money - lenders who produce only physical capital goods using both labor and capital but do not consume final goods because they do not have enough money - . Borrowers use physical capital goods produced by lenders as inputs when producing final goods [Kimura et al.,1999]. Kimura et al.’s model shows that lenders’ accumulation rate increases with borrowers’ demand rate for loans because borrowers’ demand rate depends positively upon borrowers’ expectation about future prices - borrowers will borrow more when they expect higher future prices - , while lenders’ demand rate depends negatively upon their expectation about future prices - lenders will supply less loans when they expect higher future prices - .
In our model we introduce “borrower firms” who produce final goods using only labor but cannot hold physical capital because they do not have enough money - , “lender firms” who produce only physical capital goods using both labor and capital but do not consume final goods because they do not have enough money - , “capital good producers” who produce physical capital goods using only labor but cannot hold
