Predictive Maintenance: Zero to Deployment in Manufacturing

April 7, 2020 | Nagdev

Predictive maintenance has been seen as a holy grail for cost cutting manufacturing. There are various steps involved in just feasibility study such as problem identification, sensor installation, signal processing, feature extraction and analysis, and finally modeling. Once a reliable and robust model is developed, the model has to be ...

Simulating your Model Training for Robust ML Models

March 27, 2020 | Nagdev

In this post, I will explain you why one should run simulations on their model training process so the models don’t fail in production. Traditionally we are always used to training models at certain split ratio’s of say, 70:30 or 80:20. The fundamental issue with this is that we don’...

EnsembleML: An R package for Parallel Ensemble Modeling in R

November 2, 2019 | Nagdev

Ensemble in machine learning is being used for a while. Ensemble is a concept of training multiple machine learning models and using them for predicting using either voting or feeding the prediction result to a different machine learning model. You could also build ensemble of ensembles. So, this is pretty ...
