    How to build your own Neural Network from scratch in R

    2018/10/09 by Andy Merlino

    Last week I ran across a great post on creating a neural network in Python. It walks through the very basics of neural networks and creates a working toy example using Python. I enjoyed the simple hands on approach the author used to communicate both the narrative and the code, and I was interested to see how we might make the same model using R.

    Machine Learning for Insurance Claims

    2018/09/18 by Andy Merlino

    We are pleased to announce a new demo Shiny application that uses machine learning to predict annual payments on individual insurance claims for 10 years into the future. This post describes the basics of the model behind this Shiny app, and walks through the model fitting, prediction, and simulation ideas using a single claim as an example.

    shinyFeedback 0.1.0 on CRAN

    2018/08/21 by Andy Merlino

    The version 0.1.0 release brings snackbar notifications to the package. Snackbars are useful for notifying a user that something has happened without getting in the users way. For example you could show a 'Form Submitted Successfully' snackbar after the user clicks on a form's submit button. The snackbar would display at the bottom of the page and fade after a few seconds.

    Atlanta R Users Presentation

    2018/06/10 by Andy Merlino

    These are the slides from my presentation at the April Atlanta R User meetup. I wanted to share the slides because they use the ioslides Rmarkdown template to directly embed Shiny applications into the presentation, and I found this to be pretty cool. There are Shiny apps on slides 5 and 6.

    Example Shiny App - Interest Rate Walk

    2017/11/28 by Andy Merlino

    This Shiny app demonstrates the Cox-Ingersoll-Ross interest rate walk and an interest rate walk conducted using a bootstrap resampling technique. The code used to create this app is available on GitHub. Assuming you have the necessary packages installed, you should be able to run this Shiny app on your local computer. A live version of the app is also available.

    Simulating Insurance Claims

    2017/11/12 by Andy Merlino

    When I was fresh out of college, my boss asked me to run some simulations in R. This was my first exposure to R, and I was initially skeptical of its practical usefulness. But with some Googling and a little perseverence, I overcame the initial frustrations and am now about the biggest R fanboy around. This tutorial gives a basic introduction to simulations in R using an example from my first R project (simulating insurance claims).
