SUMMARY: The purpose of this project is to construct a predictive model using various machine learning algorithms and to document the end-to-end steps using a template. The Sonar Dataset is a binary classification situation where we are trying to predict one of the two possible outcomes.
INTRODUCTION: The Sonar Dataset involves the prediction of whether an object is a mine or a rock given the strength of sonar returns at different angles. The dataset contains the patterns obtained by bouncing sonar signals off a metal cylinder or a rock at various angles and under various conditions. The transmitted sonar signal is a frequency-modulated chirp, rising in frequency. The data set contains signals obtained from a variety of different aspect angles, spanning 90 degrees for the cylinder and 180 degrees for the rock.
ANALYSIS: The baseline performance of the model achieved an average accuracy score of 79.48%. Using the same training parameters, the model processed the test dataset with an accuracy of 82.69%, which was even better than results from the training data.
CONCLUSION: For this dataset, the model built using Keras and TensorFlow achieved a satisfactory result and should be considered for future modeling activities.
