The idea of the auto was to create the C++ compiler to figure out the data type while compiling rather than making you declare the data type every time. Also, C++’s auto Keyword makes life simple.

Let’s say you have documented a piece of code that can operate on OSes like Linux, Windows/Mac, which makes C++ machine-independent but the executable file of the C++ cannot operate on other operating systems.Ĭ++ is a simple language, programs can be broken down into logical units and it has rich library support and a myriad of data types. Let us comprehend this characteristic of C++ with this instance. Let us take a look at the features of C++Ī C++ executable is machine-independent and not platform-independent (compiled programs on Linux won’t operate on Windows). Though being a middle-end language C++ is still close to C it can be utilized for low-level manipulation owing to its close relation with machine language. Now, C++ is still very admired for its impressive portability which lets programmers create programs that can operate on various operating systems or platforms very efficiently. Owing to its elevated scalability and flexibility, C++ can be utilized to create a wide range of applications, browsers, softwares, GUIs (Graphical User Interfaces), OSs (operating systems), and games and many more.
Nevertheless, it does not only back object-oriented, but also procedural and functional. With time, C++ has stayed a very practical language not limited to just computer programming but in introducing new programmers regarding the working of object-oriented programming.
Some anoint C++ as “C with classes” owing to the fact that it brings forth the principles of object-oriented programming, like the utilization of defined classes, to the framework of the C programming language. It was designed as a cross-platform improvement of C to equip programmers with a more elevated degree of command over memory and system resources. Bookshop Management System Using C++Īs a part of the evolution of the C family of languages, C++ is designed by renowned computer scientist Bjorne Stroustrop. So let’s define the grid of hyperparameter values and convert them to a single dictionary format. One of GridSearchCV’s parameters is a dictionary of the grid of parameters. Grid searching in scikit-learn is possible using the GridSearchCV() function from the model_selection module. For simplicity, we’ll grid search over these:
A quick review of scikit-learn ’s documentation for logistic regression reveals several hyperparameters. With this in mind, let’s do a grid search of our model’s hyperparameters. For each run of the model, we keep track of how well the model could predict credit card approvals for a specified accuracy metric and keep track of the hyperparameters used. This tuning consists of selecting hyperparameters to test, then running our model with various values of these hyperparameters. Hyperparameters are the model’s parameters that we can tweak before training occurs. Our model produced an accuracy score of nearly 84%, which is pretty good. Improving our model with hyperparameter tuning Likewise, predictions of “Approved” that were approved ( or true positives) are in the 1, 1 square. For example, for predictions of “Denied” that were denied ( or true negatives), we look at the 0, 0 square of the matrix. When we have a binary result, the confusion matrix is a 2x2 matrix that shows how your predictions faired across the two outcomes. When making predictions, especially when there’s a binary outcome, the confusion matrix is one of the first outputs we should review. Logistic regression classifier has accuracy of: 0.8421052631578947 array(, ]) A glance at the dataset shows that all the feature names are anonymised to protect the data’s confidentiality. Let’s start with loading and viewing the dataset. Once our data is in good shape, we will proceed to build a model that can predict whether an individual’s application for a credit card will be accepted.To ensure our model can make good predictions, we’ll need to preprocess the dataset.We’ll inspect the data and find that it contains numerical and categorical features, values of different ranges, and a few missing entries.We’ll begin by loading and viewing the dataset.We’ll use a dataset about credit card approvals. Author's note: * Some outputs are not included to keep this article short. In this article, we will build an automatic credit card approval predictor using machine learning, and hopefully get yourself a promotion! 🤩. Your manager wants you to find a way to automate this task with the power of machine learning. Your bank has had to manually analyse these applications in the past, which is mundane, error-prone and time-consuming (and time is money!). Recently, your bank has been receiving many applications for credit cards. You work for a commercial bank in Australia.
