This post highlights the various value-additions that machine learning can provide to actuaries in their analytical work for insurance companies. As such, a key problem of swapping specific risk for systematic risk in general insurance ratemaking is highlighted along with key solutions and applications of machine learning algorithms to various insurance analytical problems.
‘In pricing, are we swapping specific risk for systematic risk?’

Up till recent past, the artificial intelligence portion of data science was looked upon cautiously due to its history of booms and flops. In the latest stream of events, major improvements have taken place in this field and now deep learning, the new leading front for Artificial Intelligence, presents promising prospect for overcoming problems of big data. Deep learning is a method of machine learning that undertakes calculations in a layered fashion starting from high…Continue

In this case study for Complexity Science, we aim to show its value addition through agent based modeling of an important insurance problem, i. e, underwriting cycle. Underwriting in Property-Casualty/General Insurance is where insurance underwriting follows and mimics the Economy and its cycles of boom and busts. These soft and hard market swings are a key source of challenge and volatility to insurers. The main value addition of…Continue
It is quite difficult at first to precisely define ‘Complexity Science’. It is a new perspective of methodology and modeling approaches that are based more on reality than assumptions. Quite simply put, Complexity Science is a new way to grasp and manage reality. It does not study systems in isolation like gambling dice or planetary motion only. It studies the complex, holistic, inter-connected reality in which we actually live such as financial stock…Continue
Topology is the mathematical study of the properties that are preserved through deformations, twistings, and stretchings of objects. Tearing, however, is not allowed. Topology can be used to abstract the inherent connectivity of objects while ignoring their detailed form. Put simply, Topology is a mathematical discipline that studies shape and assumes that shape has meaning. This post discusses topology’s applications in finance and insurance. While…Continue
This is a quick, short and concise tutorial on how to impute missing data. Previously, we have published an extensive tutorial on imputing missing values with MICE package. Current tutorial aim to be simple and user friendly for those who just starting using R.
I have created a simulated dataset, which you can load on your R environment by using the…

Canada will soon be passing legislation to allow for physician-assisted suicide. Sometime over the course of debate between our Parliament and Senate, I found what at the time seemed like a peculiar pattern of woodchips in the back of my pick-up. It was such an interesting image, I thought I would share it here. On closer inspection, I discovered that in fact I was looking at hundreds of tiny flower shafts and seeds.…Continue

This blog about machine learning was written by Emily Barry. Emily is a Data Scientist in San Francisco, California. She really loves emoji. Another thing she loves is data science. The more she learns about machine learning algorithms, the more challenging it is to keep these subjects organized in her brain to recall at a later time. So, she decided to marry these two loves in as productive a fashion…Continue
Financial institutions are under tremendous pressure to comply with regulatory and securities laws. Traditional methods of compliance relied on hand-coded rules that provided detailed control, but introduced human bias and yielded false negative results. Ensuring compliance is complicated by diverse channels such as email, chat, instant messaging, social media, and a…Continue

2014 was a watershed moment in Indian politics for a variety of reasons. The foremost one was the stupendous victory of the Narendra Modi led NDA in the 2014 Lok Sabha elections. Modi managed to win 282 seats for his party in the elections, the first time in 30 years that a political party had come to power with absolute majority.
Several reasons have been attributed to this victory. Political analysts have spent hours in TV newsroom debates discussing the reasons for this victory.…Continue
