Comparison of Deepnet & Neuralnet

Guest blog post by Blaine Batman. Based on two R packages for neural networks.

In this article, I compare two available R packages for using neural networks to model data: neuralnet and deepnet. Through the comparisons I highlight various challenges in finding good hyperparameter values. I show that some needed hyperparameters differ when using these two packages, even with the same…

Reimagining the Airport Experience: How Big Data and AI Could Transform Air Travel

An uncomfortable airport experience can put a major damper on even the most enjoyable travel plans. Between the pre-flight security scans, wait times, and baggage claim lines, passengers often feel ready for a vacation as soon as they arrive. While TSA continues to tighten down security procedures, leaders in the tech world are converging to develop new smart systems that, if…

Leveraging Fuzzy String Matching In Competitive Intelligence

Product comparison is one of the crucial aspects of competitive intelligence (CI). There are two modes of  product comparison:

  1. Comparison of own product price across multiple channels
  2. Comparison of own product price with suitable competitor product

But, the greatest challenge in this journey is how to get the correct…

What is Big Data And How Does It Work?

Your technology is generating data whenever you use your smartphone, when you chat with your family and friends on Facebook, and when you shop. Anytime you go online, you’re producing data and leaving a digital trail of information. All of this data is very complex, there’s so much of it from many different sources, and it's coming in…

Data Monetization? Cue the Chief Data Monetization Officer

Data Monetization! Data Monetization! Data Monetization!

 It’s the new mantra of many organizations. But what does “data monetization” really mean, how do you do it, and more importantly, who in the organization owns the job of “data monetization”?

The role of Chief Data Officer (CDO) would seem to be a godsend to answer the data monetization challenge. They should be the catalyst in helping organizations to…

An Open Computational System Brings Slim Databases

As stated in the last article, database obesity due to numerous intermediate tables and stored procedures is rooted in the closed computational system. If there is an independent computing engine providing computing capability independent of databases, then the latter can lose weight.

 

With a separate computing engine, the database-generated intermediate data doesn’t have to be stored as data tables; instead, it can be stored in the file system to be further computed…

Judging Health Through Metrics of Conformance

I have written in the past about the difference between market demand and operational capacity - and how difficult it is to determine what exactly is being measured in relation to either.  Has the demand for a product declined, or is the organization simply less capable of satisfying it?  For example, the fact there are no bananas in the grocery store does not mean that there is no demand for bananas; but the absence of revenues from the sale of bananas might be regarded, rather erroneously,…

Maintenance Transformation

Many companies are leaning toward upgrading their legacy maintenance systems.  Maintenance is a very complex area to change because it often integrates to multiple divisions within a corporation. The beginning process of discovery and initial planning and review are critical to make sure the transition, which often has to occur in phases, is done most effectively.

Projects can include several fully functioning corporate acquisitions, over years, which make the transition extremely…

How to Create a Smart City with IoT and Big Data

These days, it seems like every city is trying to implement “smart” initiatives. Take Singapore for example, now known for the most extensive effort to collect data on citizens’ daily living habits/routines ever attempted by a municipality. Even Bill Gates has pumped millions of dollars into helping Phoenix in their smart city efforts.

But what do we mean when we talk about a “smart city”? Is it the better use of resources within the city center, or the fact that all resources being…

Things to watch out for when using deep learning

Deep learning has provided the world of data science with highly effective tools that can address problems in virtually any domain, and using nearly any kind of data. However, the non-intuitive features deduced and used by deep learning algorithms require a very careful experimental design, and a failure to meet that requirement can lead to miserably flawed results, regardless of the quality of the data or the structure of the deep learning network.

I first noticed such flaws almost…
