On 7 June, 2023, at 6pm UK time (1pm EDT), we will be presenting in the webinar Dash in Action: Image Processing, Forecasting, NLP. This is a community showcase hosted by Plotly, a company in Canada which makes the graphing software Plotly.
Sign up for the webinar at https://go.plotly.com/dash-in-action!
The speakers come from a variety of backgrounds, organisations and industries, all over the world:

We will be presenting the following apps:
Thomas Wood has developed a dashboard funded by the Bill and Melinda Gates Foundation to analyse the risk of a clinical trial failing. The Foundation had a number of incoming clinical trials and they had a need to identify risk factors and triage the trials. When someone runs a clinical trial, they write a 200-page document which is called a protocol, which describes how the trial will be run, where it takes place, how many participants are needed, and how the data collected will be analyzed. Thomas built some natural language processing models which can identify risk factors in the text, and developed a front end in Dash allowing users to run the models and understand the decision making process.

Gabriele Albini has developed a dashboard which allows users to experiment with sARIMA models (seasonal autoregressive integrated moving average). sARIMA models are models which allow us to predict time series with seasonality. For example, you may use a sARIMA model to predict daily electricity loads for a building or city, or to predict customer spend for a large supermarket.

Matteo Trachsel works for the environmental consultancy Thermoplan and has developed a dashboard which calculates the carbon footprint of coffee machine usage.

Agah Karakuzu at Polytechnique Montréal has built the RRSG 2020 Dashboard to accompany a scientific article on MRI. Neuroscientists are interested in a value called T1, which is the time it takes water molecules in the brain to return to their original state following a magnetic pulse. The purpose of the study was to assess the reproducibility of T1 values across different sites and vendors where researchers used the same research protocol. The dashboard allows researchers to compare datasets from brains and phantoms (calibration devices containing water, used to test MRI machines) from the three main MRI machine vendors (Phillips, GE and Siemens). This will be demonstrated by his colleague Nadia Blostein.

This new video explains natural language processing: what it is, how it works, and what can it do for your organisation. Natural Language Processing (NLP) is a branch of Artificial Intelligence (AI) that focuses on giving computers the ability to understand human language, combining disciplines like linguistics, computer science, and engineering.

This free A/B test calculator will help you compare two variants of your website, A and B, and tell you the probability that B is better. You can read more about A/B testing in our earlier blog post on the subject. You may also be interested in our Chi-Squared sample size calculator which will help you calculate the minimum sample size needed to run a Chi-Squared test, given an expected standardised effect size.

See also: Fast Data Science A/B test Calculator (Bayesian) A/B testing is a way you can test two things, Thing A, and Thing B, to see which is better. You most commonly hear about A/B testing in the context of commercial websites, but A/B testing can be done in a number of different contexts, including offline marketing, and testing prices.
