Nettet9. nov. 2024 · First, let’s start with importing some libraries that we will use at the beginning: import tensorflow as tf print (tf.__version__) import numpy as np import … NettetUse a Sequential model, which represents a sequence of steps. There are two steps in your single-variable linear regression model: Normalize the 'horsepower' input features using the normalization preprocessing layer. Apply a linear transformation ( \ (y = mx+b\)) to produce 1 output using a linear layer ( dense ).
Nettet18. okt. 2024 · In this case, since we are training a single variable linear regression, the num_features is set to 1. Declaring Variables. Variables in tensorflow are the ones that are trained. In our case, W and B. Nettet7. des. 2024 · Let's check the values of the trained variables after fitting the data. Since we are defining a deterministic linear regression, we have two variables, the slope and the intercept. In the above equation, the slope was equal to 1 and the intercept to 0. We were able to retrieve them successfully. model.weights.
