Missing data present significant challenges to trend analysis of time series. Straightforward approaches consisting of supplementing missing data with constant or zero values or with linear trends can severely degrade the quality of the trend analysis, which significantly reduces the reliability of the trend analysis. …

Summary: The addition of AI capabilities to our personal devices, applications, and even self-driving cars has caused us to take a much deeper look at what we call ‘User Experience’ (Ux). A more analytical framework identified as Cognitive Ergonomics is becoming an important field for data scientists to understand and implement.

With the rise of Big Data has come the accompanying explosion in roles that in some way involve data. Most who are in any way involved with enterprise technology are at least familiar with them by name, but sometimes it’s helpful to look at them through a comprehensive lens that shows us how they all fit together. In… Continue

Much like Dr. Frankenstein’s creation, the modern Data Scientist is made up of different parts to fully create an unstoppable data science Prometheus. To get ahead, you must exhibit both technical and soft skills; a smorgasbord of different technical, personal and business skills.
Frankenstein made a monster of different body parts, so let's have a bit of fun this Halloween, and see what his Data Scientist be made… Continue

The difficulty to migrate a stored procedure to other databases is always a subject of criticism. This is seldom forgotten every time when the shortcomings of the stored procedure are listed.
The migration of a stored procedure for handling the complex business logic is particularly problematic because its coding depends on the unique features and syntax of different databases and thus it needs to be recoded with the database changed. The cost won’t be very high if… Continue

What is SAP Fiori? Well, in simple words, the Fiori buzz can be defined as newly written series of apps by SAP which is meant to address most frequently and broadly practiced SAP functions- like information lookups, workflow approvals & self-service tasks. It’s to stress here that SAP is building the Fiori applications on its state of the art SAPUI5 user-interface framework.
Earlier business software programs often lacked a smooth user experience but Fiori is claimed to change all… Continue

The logistic map is the most basic recurrence formula exhibiting various levels of chaos depending on its parameter. It has been used in population demographics to model chaotic behavior. Here we explore this model in the context of randomness simulation, and revisit a… Continue

This blog was written with the thoughtful assistance of David Leibowitz, Dell EMC Director of Business Intelligence, Analytics & Big Data
So data warehousing may not be cool anymore, you say? It’s yesterday’s technology (or 1990’s technology if you’re as old as me) that served yesterday’s business needs. And while it’s true that recent big data and data science technologies, architectures and methodologies seems…

A person will ordinarily search the contents of a database using matching keywords and tags. Sophisticated databases might allow for filtering: for example using NOT, AND, OR on a number of keyword strings such as both titles and product descriptions. It is not normally possible to submit, say, a personality profile to a database - or a personality profile and a setting. Searching for “serial murders subway terminals” might lead to event information about precisely this, apparent serial… Continue

One of the main goals in the Bitcoin analytics is price forecasting. There are many factors which influence the price dynamics. The most important factors are: the interaction between supply and demand, attractiveness for investors, financial and macroeconomics indicators, technical indicators such as difficulty, how many blocks were created recently, etc. A very important impact on the cryptocurrency price has trends…

When I was beginning my way in data science, I often faced the problem of choosing the most appropriate algorithm for my specific problem. If you’re like me, when you open some article about machine learning algorithms, you see dozens of detailed descriptions. The paradox is that they don’t ease the choice.
In this article, I will try to explain basic concepts and give some intuition of using different… Continue

Research fields usually follow the practice of categorizing continuous predictor variables, and they are the same who mostly use ANOVA. They often do it through median splits, the high value above the median and the low values below the median. However; this it seems is not that good an idea, and enlisted are some of the reasons to it:
- Median tends to vary from sample to sample. This makes the categories in various samples have various…
