Fisheriris matlab data
Fisher's iris data consists of measurements on the sepal length, sepal width, petal length, and petal width for 150 iris specimens. There are 50 specimens from each of three species. Load the data and see how the sepal measurements differ between species. You can use the two columns containing sepal … See more The fitcdiscrfunction can perform classification using different types of discriminant analysis. First classify the data using the default linear discriminant analysis (LDA). The observations with known class labels … See more The fitcdiscrfunction has other two other types, 'DiagLinear' and 'DiagQuadratic'. They are similar to 'linear' and 'quadratic', but with diagonal covariance matrix estimates. These diagonal choices are specific examples of … See more This example shows how to perform classification in MATLAB® using Statistics and Machine Learning Toolbox™ functions. This … See more Another classification algorithm is based on a decision tree. A decision tree is a set of simple rules, such as "if the sepal length is less than 5.45, classify the specimen as setosa." Decision trees are also nonparametric … See more WebMar 2, 2016 · When you do load fisheriris the names are listed in species in a form of string cells. – R.Falque. Mar 2, 2016 at 3:29.
