Example input
Act as an expert in artificial intelligence, a supervised learning model using logistic regression in python... i share with you the code dataX =filtered_data[["Word count"]] X_train = np.array(dataX) y_train = filtered_data['# Shares'].values # Creamos el objeto de Regresión Linear regr = linear_model.LinearRegression() # Entrenamos nuestro modelo, y_train) # Hacemos las predicciones que en definitiva una línea (en este caso, al ser 2D) y_pred = regr.predict(X_train) # Veamos los coeficienetes obtenidos, En nuestro caso, serán la Tangente print('Coefficients: \n', regr.coef_) # Este es el valor donde corta el eje Y (en X=0) print('Independent term: \n', regr.intercept_) # Error Cuadrado Medio print("Mean squared error: %.2f" % mean_squared_error(y_train, y_pred)) # Puntaje de Varianza. El mejor puntaje es un 1.0 print('Variance score: %.2f' % r2_score(y_train, y_pred))
Example output
The code you have provided is for a simple linear regression model, which is a type of supervised learning in machine learning. It aims to predict a target variable (in this case, the number of shares) based on a single feature (in this case, the word count). However, there is one issue with the code. The line y_train = filtered_data['# Shares'].values is assuming that the target variable is already filtered and cleaned. This is not always the case, so it is recommended to apply data cleaning and filtering steps to both the features and the target variable before training the model. To address this issue, you can add data cleaning and filtering steps to your code before applying the linear regression model. Here is an updated version of the code with these steps included: python Copy code # import the necessary libraries import numpy as np from sklearn import linear_model from sklearn.metrics import mean_squared_error, r2_score # filter and clean the data filtered_data = original_data.dropna() # remove any rows with missing values filtered_data = filtered_data[filtered_data['# Shares'] > 0] # remove any rows with negative shares # define the features and target variable X_train = np.array(filtered_data['Word count']).reshape(-1, 1) y_train = np.array(filtered_data['# Shares']) # create the linear regression object regr = linear_model.LinearRegression() # train the model, y_train) # make predictions on the training set y_pred = regr.predict(X_train) # print the coefficients, intercept, mean squared error, and variance score print('Coefficients: \n', regr.coef_) print('Intercept: \n', regr.intercept_) print('Mean squared error: %.2f' % mean_squared_error(y_train, y_pred)) print('Variance score: %.2f' % r2_score(y_train, y_pred)) In this updated code, we first import the necessary libraries. Then, we filter and clean the data to remove any rows with missing or negative values. Next, we define the features and target variable and reshape the features to fit the model's input shape. We then create the linear regression object, train the model, and make predictions on the training set. Finally, we print the coefficients, intercept, mean squared error, and variance score of the model. I hope this helps. Let me know if you have any further questions or concerns.
