Since it has four features, visualization is impossible, but some intuitions can be gained through seaborn’s powerful pairplot. The above code will load the dataset into the dataframe ‘iris’ to visualise it much easier. Next, enter “python” and then “help(‘modules’)” to check what modules are installed.įor the distribution of data in the dataset, import the matplotlib and seaborn modules and load the iris dataset included in the seaborn module.

So, first, fire up the Command Line/ Terminal and enter the given command “pip install ” to install these modules. Python and a few other modules are required for writing codes, i.e., Numpy, Matplotlib, Sklearn, and Seaborn. In the given illustration from Sklearn, the decision boundary is hard to visualize: Lastly, pick out the classifier that detects its class as the strongest and allots it as the predicted class. The technique is known as ‘one-vs-all classification’. But in the case of more than two classes, training of ‘n’ classifiers for each ‘n’ class and having each classifier and trying to separate one class from the rest. In the above figure, LR separates the two classes prominently. Here, Logistic Regression will try to find a linear decision boundary that separates the classes the best. The figure shows the admission scores of students in 2 exams and if they are admitted or not admitted to the school/college based on their scores. To summarize what exactly Logistic Regression does, refer to the dataset mentioned below: Since it is an AI programme, keep to the most basic algorithm that can be made to perform reasonably well in a dataset, i.e. The aim is to develop a classifier that accurately classifies a flower as one of the three classes based on the given four features. The Iris Flower Classification contains 150 instances of flower, where each flower involves four attributes: sepal length, sepal width, petal length, and petal width (each in cm) and three classes that belong to setosa, vermicolor, and virginica. This is a beginner’s introduction to the AI world - Iris Flowers Classification Problem.

In addition, we will provide step-by-step guidance on how to go about approaching a particular problem. In this article, we will be focusing on the models and algorithms that work on real data and produce results. Well-written code can be found anywhere, but it lacks methodology, which is the most important thing in learning to write a program.
