Leveraging Efficientnet architecture to achieve 99%+ prediction accuracy on a Medical Imaging Dataset pertaining to Covid19
In this post, I will share my experience of developing a Convolutional Neural Network algorithm to predict Covid-19 from chest X-Ray images with high accuracy. I developed this algorithm while participating in an In-Class Kaggle competition for a Ph.D. level course on Deep Learning that I took at the University of Waterloo. I was happy to learn from the final competition Leaderboard that I stood 1st in the competition amongst 40 participating Ph.D. and Masters students of Statistics and Computer Science departments! Instead of…
In this post, I will describe my experience working on finding the maximum value in a multivariate optimization problem where the response value was unknown. I worked on this problem in the final project of a graduate course in Experimental Design that I took at the University of Waterloo
Often, in scientific and engineering settings and sometimes even in business settings, we come across quantitative problems where we know the input values and their ranges and are the provided the corresponding output (response) values but have no idea about the relationship between them. When it can be safely assumed…
Algorithmic Risk Prediction for Life Insurance Applications through supervised learning algorithms — By Bharat , Dylan , Leonie and Mingdao (Jack)
In part 1, we described data pre-processing and dimensionality reduction for the Prudential Life Insurance Dataset. In this part we will describe the learning algorithms that we applied to the transformed dataset and the results that we obtained.
The link to the project GitHub repository is here
We have used four supervised learning algorithms on the dataset: Logistic Regression, Neural Networks, Random Tree, and RepTree. There are of course many other algorithms that can be used including XGB…
In this two-part series, we will describe our experience of working on the Prudential Life Insurance Dataset to predict the risk of life insurance applications using supervised learning algorithms. We worked on this dataset as a part of our final group project in a graduate course on Statistical Learning that we took at the University of Waterloo in which we reproduced the results of a paper¹ and improved upon the work of the authors.
Companies that underwrite life…
In Part 1(you can read it here), I discussed the Business Case for Predicting Visitor-to-Customer Conversion for an Online Store and covered Exploratory Data Analysis of the training dataset.
In this part, I will cover Data Preprocessing and the Application of Supervised Learning Algorithms, namely RandomForest and XGBoost to the prepared training dataset.
So without further ado, let’s go to Data Preprocessing!
“What you sow, so you reap”. This proverb, so true for life in general is also very much true for Data Science ! …
In this two part series, I will write about my experience working on a Kaggle Data Challenge (Here’s the Link) as a part of a graduate course on Statistical Learning that I took at the University of Waterloo as a Masters Student in Statistics.
In the first part, I will talk about the following two topics:
So, let’s dive in straight into the problem:
The owner of an online jewellery shop wants to figure out a way to increase her revenues. …
