Cross validation is a technique commonly used In Data Science. Most people think that it plays a small part in the data science pipeline, i.e. while training the model. However, it has a broader application in model selection and hyperparameter tuning.
Let us first explore the process of cross validation itself and then see how it applies to different parts of the data science pipeline
Cross-validation is a resampling procedure used to evaluate machine learning models on a…Continue
As a teacher of Data Science (Data Science for Internet of Things course at the University of Oxford), I am always fascinated in cross connection between concepts. I noticed an interesting image on Tess Fernandez slideshare (which I very much recommend you follow) which talked of…Continue
Understanding the maths behind forward and back propagation is not very easy.
There are some very good – but also very technical explanations.
For example : The Matrix Calculus You Need For Deep Learning Terence Parr and Jeremy Howard is an excellent resource but still too complex for beginners.
I found a much simpler explanation in the ml cheatsheet.
Automated machine learning is a fundamental shift to machine learning and data science. Data science as it stands today, is resource-intensive, expensive and challenging. It requires skills which are in high demand. Automated Machine learning may not quite lead to the beach lifestyle for the data…Continue
