please help
% Step 1: Data Exploration and Preprocessing
% Load the dataset
data = readtable('creditcard_csv.csv'); % Assuming the dataset is saved as 'creditcard.csv'
% Display basic information about the dataset
summary(data)
% Select features (Assuming 'V1' to 'V28' are the features)
features = data(:,{'V1','V2','V3','V4','V5', 'Class'});
% Step 2: Split the data into training and testing sets
cv = cvpartition(size(features,1), 'HoldOut', 0.2); %80% train, 20% test
idxTrain = training(cv);
idxTest = test(cv);
% Separate features and labels
X_train = features{idxTrain,1:end-1};
Y_train = features{idxTrain, end};
X_test = features{idxTest,1:end-1};
Y_test = features{idxTest, end};
% Step 2(continued): Model Training and Evaluation
% Train models using Classification Learner App
% Make sure to export the model with the highest accuracy
% After training, export the model with the highest accuracy to MATLAB workspace
% Replace 'YourBestModel' with the variable name of your best model
% Ensure to replace 'YourModelName' with a descriptive name for your model
% Example:
% exportModel(YourBestModel, 'YourModelName');
% Step 3: Testing and Evaluation
% Evaluate the models using testing data
% Y_pred = predict(best123, X_test);
Y_pred = YourBestModel.predictFcn(X_test);
% Calculate accuracy
%accuracy = sum(Y_pred == Y_test)/ numel(Y_test);
% Calculate accuracy
accuracy = sum(strcmp(Y_pred, Y_test))/ numel(Y_test);
% Display confusion matrix
confMat = confusionmat(Y_test, Y_pred);
disp(confMat);
% Step 3: Application Development
% Open MATLAB App Designer and create a new app
% Design the UI with necessary components like buttons, axes, etc.
% Implement functionality to upload test features, predict classes, and display the confusion matrix
% Ensure creativity and use of unique widgets as per requirements
% Provide explanations for the app design and code is this code correct for task 1.1 if not please fix it and send full answer please
Question 1:
MATLAB
1.1 Developing the Machine Learning Model
Note:, select only 5 features out of the available columns
Credit Card Fraud Detection Dataset
data set file name ( creditcard_csv.csv )
Train-Test Split: 80%-20%
Output: Output (1 or 0)
train and compare 5 machine learning models for the specific application using the Matlab Classification Learner App. Ensure to export the model with the highest accuracy.
make sure to include these in your code:
Introduction
Database Loading, Pre-processing, and Train-test split
Training process Screenshot and Training Results
Testing, Confusion Matrix, accuracy, and saved model
Explanations for each step
Conclusion
1.2 Developing the Application or Website
Using the model that you saved in Task 1, use Matlab App Designer. to create a user interface application that satisfies the following requirements:
a) Allows the user to upload test features.
c) Implements the model saved in Task 1 to determine the class of the features uploaded.
d) Provides an option to display the confusion matrix in Task 1 within a separate Axes.
e) Ensure creativity and use of unique widgets
f) Explanation of the app design and code
