Feature Selection made easy with ‘screenpredictors’

Pre-processing of features or predictor variables for the development of machine learning models is usually a tedious process. The MathWorks has come to the rescue with a function called screenpredictors that was released with the R2019a MATLAB version. Several customers have commented on its usefulness, which is why I’ve been inspired to write this post.

AI in Industry 4.0: I have all this sensor data… Now what?

Predictive maintenance uses data to monitor the condition of equipment. Using fourth industrial revolution techniques means reduced failures, less machine downtime, reduced maintenance costs, and so much more. Most industrial plants collect large amounts of sensor data from their equipment. The sheer volume of data may leave most people thinking “What now?”. Using this data to inform smart business decisions requires a rare combination of both domain and statistical expertise.

Smart Manufacturing: From Simulation to Implementation

More and more manufacturers are adopting a new approach to process optimisation by integrating practical advances in technology into their day-to-day operations. The concept is built around developing a plant-wide collaborative process that results in efficiency gains that would otherwise have been missed. Many global tech and industry experts believe that this approach is the […]

AI in Finance: Using Deep Learning for RegTech

Regulatory Technology (RegTech) refers to the use of new technology such as Artificial Intelligence to improve how companies adhere to regulatory requirements. The RegTech app, developed in MATLAB, aims to accelerate and automate tedious regulatory data extraction processes. Data capturers at financial institutions constantly capture data from IDs, payslips and proofs-of-address. By using deep learning […]
