The life cycle of a machine learning models involves a training phase, where a typical data scientist develops a model with good prediction based on historical data and features extracted from the data at hand. This model is then put into production with the hope that it would continue to have similar predictive performance during…

The Curse of Dimensionality is termed by mathematician R. Bellman in his book “Dynamic Programming” in 1957. According to him, the curse of dimensionality is the problem caused by the exponential increase in volume associated with adding extra dimensions to Euclidean space. The curse of dimensionality basically means that the error increases with the…

Dimensionality Reduction is an important and necessary step when we have a big data in hand with so many features. When there are so many features or columns, it is hard to understand the correlation between them. Including weak links or correlations in training-data can also result in an inaccurate prediction by the model. Dimensionality…
