Utilizing multi-core processor for classification in WEKA

Currently, WEKA is one of the most favorites machine learning tools. Without programming skills, you can do severe classification, clustering, and extensive data analysis. For some time, I’ve been using its standard GUI features without thinking much about performance bottlenecks. But since research are becoming more complex by using ensemble, voting, and other meta-algorithms that generally are based on multiple classifiers running simultaneously, the performance issues start becoming annoying. You need to wait for hours until the task is completed. The problem is that when running classification algorithms from the WEKA GUI, they utilize a single core of your processor. Such algorithms as Multi-layer Perceptron running 10-fold cross-validation is calculating one cross-fold at the time on one core, taking a long time to accomplish: So I started looking for options to make it use all cores of the processor as separate threads for each operation fold. There are a couple of options available to do so. One is to use WekaServer package, and another is remote host processing. This time we will focus on WekaServer solution. The idea is to start a WEKA server as a distributed execution environment. When starting the server, you can indicate how many cores you…

How Modern Technology Has Helped Improve Weather Forecast

On October 17th, 2014, the hurricane named Gonzalo hit the island named Bermuda. It did severe damage by knocking down power lines and many trees and completely destroying access to many, many roads. However, due to early warnings, Bermuda residents could avoid the disaster areas. The warnings were so adequate that not one death or even serious injury was reported. It’s common knowledge that storms can be hard to predict because of many factors. It is nature, so it’s tough to see what all the potential factors would be for a storm because so many different things can develop and so quickly. Still, scientists and weather forecasters are getting much more accurate and efficient at predicting the weather. The weather systems these days are looked at supercomputers. These computers use unique algorithms to predict the weather patterns, and also store new data. Or you can find ways to do this at home yourself in more minor ways, too, by checking out home weather station reviews. The NOAA (Located in the USA) has developed a new storm prediction system. The system is called the NEIS, and it creates 4D models that show the weather worldwide. It works by using many (millions)…

Sloth Is the Progress Booster: What Makes the Technological World Move Ahead?

Some people argue that technology advances for purely lazy reasons. For example, remote starting your car, digital entertainment replacing physical activities, and not having to leave your sofa to change the TV channel. People can even limit how much they have to walk thanks to technology. However, can we relegate the technological advancements to laziness? Below are some reasons why the forward-moving in the technological world may be happening due to more reasons than just being lazy!

Why Ethanol is a Fantastic Fuel and Source of Energy

As the modern world moves towards a renewable energy future, ethanol fuel is becoming more popular. And even though it’s not perfect, it presents a sustainable future that doesn’t cause pollution. So, here is a look at why ethanol fuel is a big focal point all over the world. Ethanol Fuel Is More Affordable Given the fact that almost every country is in a position to make its own ethanol fuel, it makes it the most affordable energy source. Basically, if a country can grow sugar cane, corn, or grains, it can start producing ethanol. And when you compare it to conventional fossil fuel, which places huge pressure on developing countries as well as those that produce it, ethanol is the logical next step. In fact, it is a clean energy source that can help to build struggling economies. According to Wall Fireplace Pros, this has led to a significant increase in interest in their ethanol range of fireplaces.

The Latest Uses of EEG Headsets

It seems astonishing that the story of electroencephalography, EEG, began back in Victorian times. The first research was published in 1875 by Liverpool physician Richard Caton. Fifty years later, the first recording of human brain activity was achieved by Hans Berger, and the EEG headset was born. The headset detects brain activity via electrodes, information which is then converted into a visual form. Throughout the twentieth century, electroencephalography was used almost exclusively for medical research, proving itself a handy tool on the diagnosis of epilepsy. Rapidly developing software that enables increasingly sophisticated analysis of the data has triggered research projects looking at the brain’s reaction to a range of external stimuli.

How to install underfloor ventilation

You may have heard of the ceiling and wall ventilation, as these standard installations can help to keep your property circulated and free of heat and dryness. But sometimes, there is extra moisture that a ceiling ventilation unit may not help with. This is where underfloor ventilation comes in handy. Underfloor ventilation is the best way to keep any building or property free of dampness that can come from weather, groundwater, or air conditioning. Having properly installed underfloor ventilation can successfully protect your property from any source of water damage. If you aren’t sure how to begin such an installation project, this quick guide can help set you in the right direction.

A Guide to Healthcare IT Disaster Recovery

The field of healthcare is a big business, and when there is a DDoS attack on a healthcare system, it can literally be akin to a catastrophe. If you go through just one DDoS attack on the multitude of IoT devices you have, you will figure how important being prepared for this possibility actually is. Healthcare disaster recovery planning is an essential tool in keeping your healthcare organization running like a top, and continuing to meet everyone’s medical needs. They say that “an ounce of prevention is worth a pound of cure,” and that is definitely a principle that rings true in cyberattack preparedness. Healthcare IT experts from TrueNorthITG recommend that you focus on the areas that are consistently identified as high risk for a potential cyberattack. One of these would simply be that many health organizations do not have an effective disaster recovery (DR) methodology. There are several principles that should be utilized:

Ventilation requirements for a healthy hospital

The Joint Commission has strict regulation when it comes to hospital ventilation. One of the requirements is to have the hospital rooms tested to see if they comply with the regulations. There are different kinds of ventilation that need to be used in different rooms. The ventilation requirements make it easy for the hospital to control infections from one room to another. It also helps keep certain rooms contained protecting the patients inside and outside the room. To understand the importance of these requirements, you need to know what ventilation is and why hospitals need pressurized rooms. Ventilation is moving air from one place to another through ducts. The air gets cleaned before it is released into the intended space. There need to be adequate ventilation facilities for the air to be thoroughly cleaned or contaminate the space with pathogens. Hospitals have stringent ventilation requirements that are crucial for the health of patients and other hospital faculty. When it comes to hospitals, there are specific rooms that need to be pressurized positively or negatively.

Why Establishing A Work Quiet Room is a Good Idea

People are not machines. And they can’t be expected to function at the top of their game all the time. With all the phone calls, emails, meetings, the noisy environment, and bright lights, it is only natural for their productivity levels to drop. Doing the same thing day in and day out can become a very dangerous routine, and it needs to be addressed by employers. And what better way to do it than provide a quiet room where only peace and relaxation exist? What Is A Quiet Room? It is a designated area where employees can spend some time gathering their thoughts so-to-speak. For example, they can meditate, pray, nap, read, or do anything else that is peaceful and relaxing. The point is to help them restore their energy and well-being away from the noise and stress their offices represent.
