Deep learning is sometimes defined as the intersection between machine learning and artificial intelligence. Many articles on deep…Continue

An image is a concept. It is a mental picture that we have about things such as an object, a person, a group, an organization, or a nation. It is our notion or belief about something that is not physically present around us.
The image of any entity, be it a product or a person or a company, is its intangible asset. For example, the reliability (hence the high resale value) of a used car stems from its positive image as a dependable…Continue

Summary: The shortage of data scientists is driving a growing number of developers to fully Automated Predictive Analytic platforms. Some of these offer true One-Click Data-In-Model-Out capability, playing to Citizen Data Scientists with limited or no data science expertise. Who are these players and what does it mean for the profession of data science?
Last Thursday, the World Bank’s data team announced the forthcoming all-new data.worldbank.org website.

One of most excruciating pain points during Data Exploration and Preparation stage of an Analytics project are missing values.
How do you deal with missing values - ignore or treat them? The answer would depend on the percentage of those missing values in the dataset, the variables affected by missing values, whether those missing values are a part of dependent or the independent variables, etc. Missing Value treatment becomes important since the data insights or the…Continue

In this blog, I will be discussing the use of attribution models in relation to codified narrative. For this purpose, I will be referring to the plots of two films: the 1974 horror classic “The Texas Chainsaw Massacre”; and a 2014 dark comedy called “Tusk.” I have my own codification system called BERLIN: this is short for “Behavioural Event Reconstruction Linguistic Interface for Narratives.” An attribution model supports the inference of meaning from data. Imagine a student one day going…Continue
