What can this visualization tool do for you?Image by Lukas Blazek on Unsplash, with enhancements by author.What’s Power BI? Can it replace good ol’ Microsoft Excel?Or do they work better together?How easy is it to create amazing visualisations?Is Power BI good for ETL and data modelling too?We’ll answer these in this demo article. Data provided!Excel suits small ad-hoc analyses. It’s great for direct data entry, organising your data and making some simple visualisations.Power BI is an industry-standard business…

Synthetic data could help mitigate fraud casesPhoto by Maxim Berg on UnsplashFraud cases are common in any business industry and cause massive financial loss. Small or Big, every business would face the fraud problem whether they like it or not — as long as there are people with bad intentions.Many efforts have been exerted in machine learning fraud detection research to mitigate the fraud problem, yet there is still no perfect solution. It’s understandable because every business has different requirements, and data is…

Lila Moss is following in her mother’s modelling footsteps as she recently starred in a new Calvin Klein campaign after Kate Moss launched her career with the brand in iconic shots in 1992. Lila took to her Instagram and shared shots from her new fashion collaboration as she flashed her abs in a sheer shirt over a crop top which bore a striking resemblance to one of Kate’s shots with the designer where she wore just a black bra. Kate first modelled for Calvin Klein 30 years ago as part of a deal which helped turn her…

Linda Evangelista Reveals Being Asked To Get N*ked By A Modelling Agency At 16: “It Aasn’t A ‘Would You Do N*des’ Conversation, It Was A…” (Photo Credit – Linda Evangelista/Instagram) Canadian fashion model Linda Evangelista fell victim to a predatory modelling agency when she was a teenager. Offered a modelling contract for the summer by a Japanese agency when she was just 16, the 57-year-old supermodel quickly left when they tried to force her into taking n*de pictures, reports aceshowbiz.com. “I…

A simple project walkthrough in fitting Generalised Linear Models in PythonPhoto by Hiroshige Fukuhara on UnsplashDespite writing several articles on the topic and working in the insurance industry, I have actually never fitted a Generalised Linear Model (GLM) from scratch.Shocking I know.So, I have decided to spread my wings and carry out a small project where I can put all my theoretical knowledge into practise!In this article, I want to walk you through a simple project using GLMs to model the bicycle crossing volumes…

Applied Machine LearningThe Similarities Between Cancer Prediction and Churn ModellingImage from Shutterstock by tadamichiIntroductionOver the past year, I have been working in a telecommunications company as a Data Scientist. The telecom sector has many applications for machine learning, one of the main ones being churn prediction. Accurately predicting churn can help improve customer retention and increase revenue in the business. Although churn prediction is seemingly unrelated to cancer prediction, these two problems…

Taking proactive measures to ensure model reliability and availability in productionPhoto by Andreas Wagner on UnsplashAs businesses increasingly move towards machine learning and analytics based solutions, challenges arise when the models are put into production. One such challenge is the drift in model predictions which makes them less reliable in the long run.Nowhere is this phenomenon more visible than time series forecast models. Changes in economic cycles, monetary policies, consumer behavior and competitor activity…

(Pexels)Why should I care about Markov Chains?Two things: first, it is a key foundation for several Machine Learning concepts such as Hidden Markov Models (HMM) and Reinforcement Learning. Markov Chains are also used in other disciplines such as Finance (stock price movements) or in Engineering Physics (Brownian motion). A famous example is PageRanks, the first algorithm that Google used to score page ranks, which was based on Markov Chains.Secondly, I find the concept in itself interesting because it is a completely…

The shrieks of delight and horror greeting Ruben Östlund’s latest film, Triangle of Sadness, are a mark of success for its award-winning Swedish director, he said on Sunday, following the film’s Cannes festival premiere. Östlund explained he intended to make a “rollercoaster experience” for adults.“People were applauding like it was a football game,” said Östlund.Östlund, best known for his 2014 alpine drama Force Majeure, which was remade in English two years ago as Downhill, may also have ably succeeded in establishing…

Machine learning programs have paved way for several research frontiers and development. These programs work in a similar way as a human, by learning new techniques and skills using trial and error methods. The process involves repetitions and reinforming learning, where the good part is selected for future use and the bad outcomes are avoided. Based on reinforcement learning, scientists at the US Department of Energy's (DOE) Argonne National Laboratory have developed an algorithm that will help in modeling the…
