The intuition behind Shannon’s Entropy

Now, back to our formula 3.49: The definition of Entropy for a probability distribution (from The Deep Learning Book) I(x) is the information content of X. I(x) itself is a random variable. In our example, the possible outcomes of the War. Thus, H(x) is the expected value of every possible information. … Read moreThe intuition behind Shannon’s Entropy

Forecasting Exchange Rates Using ARIMA In Python

Sep 29, 2018 Nearly all sectors use time series data to forecast future time points. Forecasting future can assist analysts and management in making better calculated decisions to maximise returns and minimise risks.

Object Detection using Deep Learning Approaches: An End to End Theoretical Perspective

Fast RCNN So the next idea from the same authors: Why not create convolution map of input image and then just select the regions from that convolutional map? Do we really need to run so many convnets? What we can do is run just a single convnet and then apply … Read moreObject Detection using Deep Learning Approaches: An End to End Theoretical Perspective
