Letting the Market Do the Managing

For some organizations the title might not be too meaningful, but it is meant to emphasize a conceptual point.  The managers in an organization do the managing.  They do this at least theoretically by managing resources – including people.  Then in the end, if fortune is smiling, the markets will adhere to the game plan, and the company will succeed.  However, companies routinely fail, creating products and services that the markets don’t care to purchase.  They sometimes use methods…

K Means Clustering Algorithm & its Application

What is K Means Clustering?

Clustering means grouping things which are similar or have features in common and so is the purpose of k-means clustering. K-means clustering is an unsupervised machine learning algorithm for clustering ‘n’ observations into ‘k’ clusters where k is predefined or user-defined constant. The main idea is to define k centroids, one for each cluster.

The K Means algorithm…

Using Confusion Matrices to Quantify the Cost of Being Wrong

There are so many confusing and sometimes even counter-intuitive concepts in statistics.  I mean, come on…even explaining the differences between Null Hypothesis and Alternative Hypothesis can be an ordeal.  All I want to do is to understand and quantify the cost of my analytical models being wrong.

For example, let’s say that I’m a shepherd who has bad eyesight and have a hard time distinguishing between a wolf and a sheep dog.  That’s obviously…

Convolutional Neural Network  (CNN) From Scratch

Introduction

In a regular neural network, the input is transformed through a series of hidden layers having multiple neurons. Each neuron is connected to all the neurons in the previous and the following layers. This arrangement is called a fully connected layer and the last layer is the output layer. In Computer Vision applications where the input is an image, we use convolutional neural network…
