I am unable to create the query point perfectly for the matrix multiplication.
This is my predict function.
def predict(X,Y,query_x,tau):
ones = np.ones((M,1))
X_ = np.hstack((X,ones))
qx = np.append(query_x, [1])
qx = np.mat(qx)
W = getW(qx,X_,tau)
theta = np.linalg.pinv(X_.T*(W*X_))*(X_.T*(W*Y))
pred = np.dot(qx,theta)
return theta, pred
When I run this, theta,pred = predict(X,Y,x_test[0],1.0), I am getting a valueError.
ValueError: shapes (1600,1600) and (1,1600) not aligned: 1600 (dim 1) != 1 (dim 0)
Please help.
