Auto Encoders for Anomaly Detection in Predictive Maintenance
Autoencoders is an unsupervised version of neural network that is used for data encoding. This technique is mainly used to learn the representation of data that can be used for dimensionality reduction by training network to ignore noise. Autoencoders play an important role in unsupervised learning and deep architectures mainly for transfer learn...

COVID-19 Data and Prediction for Michigan
Every country is facing a global pandemic caused by COVID19 and it’s quite scary for everyone. Unlike any other pandemic we faced before, COVID19 is providing plenty of quality data in near real time. Making this available for general public has helped citizen data scientists to share their reports, forecast trends and building real-time dashbo...

Simulating your Model Training for Robust ML Models
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’t always train models on different parts of data in those ...

Top Data Science Blogs
As a data scientist, I always seek to learn about out new tools and techniques. Although research papers are a great resource to learn, they are mostly either theoretical or lack in hands on explanation. Blogs are a great way to learn if you like me. They are concise, application oriented and doesn’t require a lot of time. There are hundreds or...

Predictive Maintenance: Zero to Deployment in Manufacturing
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 deployed t...
