Hello my AI friends!

Today, I would like to share with you skrobot!

skrobot is an open-source Python module I have created at MedoidAI for automating Machine Learning (ML) tasks. It is built on top of scikit-learn framework and follows object-oriented design (OOD) for ML task creation, execution, and reproducibility. Multiple ML tasks can be combined together to implement an experiment. It also provides seamless tracking and logging of experiments (e.g. saving experiments’ parameters).

It can help Data Scientists and Machine Learning Engineers:

  • to keep track of modelling experiments / tasks
  • to automate the repetitive (and boring) stuff when designing ML modelling pipelines
  • to spend more time on the things that truly matter when solving a problem

The current release of skrobot (1.0.13) supports the following ML tasks for binary classification problems:

  • Automated feature engineering / synthesis
  • Feature selection
  • Model selection (i.e. hyperparameters search)
  • Model evaluation
  • Model training
  • Model prediction

For more information you can check out the online documentation!

Lastly, many thanks to all contributors who helped to extend and support skrobot.

Stay safe!

Hello my friends!

Today, I would like to share with you Time Series Segmentation & Changepoint Detection!

It is an open-source R/Shiny app for time-series segmentation and changepoint detection tasks. The app acts as a front-end for R packages such as the magnificent changepoint package.

I had the pleasure of working together with wonderful colleagues at MedoidAI to develop this application. My role in this small project was more organizational and consulting.

For more information on the parameters and algorithms currently included in the app please read the following paper by Killick et al. For an overview of changepoint packages that may be included in the future please see the following page.

Stay safe!

Hi people!

I have created -just for fun- a Node.js web application that provides you a random data science image! Currently, the app is deployed in Heroku but I have limited monthly resources. So, if there is anyone who has premium account and would like to host it for free I would be grateful!

Heroku Application:

Happy Hacking!
