It has two prototasks: nox, in which the nitrous oxide level is to be predicted; and price, in which the median value of a home is to be predicted. A blockgroup typically has a population of 600 to 3,000 people. For good measure, we’ll turn the 0 values into np.nan where we can see what is missing. Let’s check if we have any missing values. I can transform the non-linear relationship logging the values. ‘RM’, or rooms per home, at 3.23 can be interpreted that for every room, the price increases by 3K. Fashion MNIST dataset, an alternative to MNIST. We can also access this data from the scikit-learn library. - LSTAT % lower status of the population This dataset concerns the housing prices in housing city of Boston. Similarly , we can infer so many things by just looking at the describe function. - CHAS Charles River dummy variable (= 1 if tract bounds river; 0 otherwise) Now we know that a "dumb" classifier, that only predicts the mean, would predict $454,342.94 for all houses. in which the median value of a home is to be predicted. For an explanation of our variables, including assumptions about how they impact housing prices, and all the sources of data used in this post, see here. I would want to use these two features. Data.
