Converting binary to decimal integer output

Question

I need to convert a binary input into a decimal integer. I know how to go from a decimal to a binary:

n = int(raw_input(\'enter a number: \'))
print \'{0:b}\'.fo         


        

Answer 1

There is actually a much faster alternative to convert binary numbers to decimal, based on artificial intelligence (linear regression) model:

1. Train an AI algorithm to convert 32-binary number to decimal based.
2. Predict a decimal representation from 32-binary.

See example and time comparison below:

from sklearn.linear_model import LinearRegression
from sklearn.model_selection import train_test_split
import numpy as np

y = np.random.randint(0, 2**32, size=10_000)

def gen_x(y):
    _x = bin(y)[2:]
    n = 32 - len(_x)
    return [int(sym) for sym in '0'*n + _x]

X = np.array([gen_x(x) for x in y])

model = LinearRegression()
model.fit(X, y)

def convert_bin_to_dec_ai(array):
    return model.predict(array)

y_pred = convert_bin_to_dec_ai(X)

Time comparison:

This AI solution converts numbers almost x10 times faster than conventional way!
