I had a recent enquiry on our NHS-R community slack channel about which package is best to work with larger datasets, such as 5 million plus records, with high dimensionality. I got to thinking that the DBI and odbc packages would be best for this purpose, as this is still not considered big data, it is more medium data with manageable dimensionality. The functions can be fiddly to understand, so I thought I would combine all the functions into one lovely function wrapper in R. Overview of the function The function below allows you to ...

I wanted to know how many downloads it has had since its release on CRAN last month. I thought shall I write a package, but alas there is one already available. The dlstats package saves the day I was searching on the old Google and I found this lovely package that does just what I need. I have created a small tutorial to show you how to build the small routine needed to ... Read More

Wednesday (20th January 2021) myself and a colleagues Andreas kicked off the first webinar of 2021 for the NHS-R Community with our look at the benefits of using reticulate for joining up R and Python. What was the webinar about? The webinar was split into two sections: The first session involved me taking the functionality of the reticulate package and how you can easily pass R and Python commands to convert the data from the respective formats. This is actually really intuitive in R and the webinar recording in the next section will show the ... Read More

The premise The premise of my talk was to take a novel Kaggle parasite cell dataset and advocate how this type of classification task could be transported to other areas such as clinical x-ray scanning, diagnostic image condition detection, etc. The live event To view the talk, have a look at the LondonR event below. I was on first and then two very interesting talks followed from ... Read More

The NHS-R conference is coming up and I have been invited to speak for the third year running, I know hat trick, as well as becoming an official fellow of the organisation, as I am now back with the NHS. This year I wanted to bring Deep Learning to the table, and my focus will be on how to apply Convolutional Neural Networks to a Kaggle Malaria cell problem. Understanding the data To understand the data I have first created two functions and prepared all my imports from the relevant R libraries: library(tensorflow) library(keras) library(plyr) ...

Watch our technical team discuss how and why you should be switching to the DSP in your healthcare organisation Introducing the DSP The webinar explains why use the DSP, how to use the DSP and what the DSP does. Under the hood The DSP uses curated machine learning (superivsed and unsupervised) machine learning algorithms alongside other algorithms, such as epidemiology curve estimations and forecasting tools. These have all be tested with customer and combined in to one easy to use ... Read More

Feed: R-bloggers. Author: Gary Hutson. Well, what can I say? It has been a blast over the past year and a half. In my time at the company I have managed to work on a number of fascinating projects, here is a list of just some of them:Data Science Platform – this has been the culmination of lots of machine learning projects, undertaken separately in R and Python, and has allowed for our Healthcare Data Science Platform to be developed. This, alongside skilled data scientists, data engineers and front end developers, we think we have developed something really specialClinical Outcome ... Read More
