Control Theory: World Heavyweight Championship fight: Sliding Mode Control vs Classic Linear u=Kx

What are the advantages of Sliding Mode Control over PID control? Originally asked on Quora.

Answer by Egor Polilov, Lead Programmer at NTR Lab, on Quora:

In control theory there are systems with a special type of motion, that are sliding modes, which have a high robustness to the additive interferences as well as provide the reduction of the system in the sliding mode and dynamics, which is no worse than one specified in the conditions of parametric uncertainty. The problem of construction of control systems with static and dynamic characteristics closed to the optimal ones according to the set criteria of effectiveness becomes urgent in the conditions of incompleteness of the initial information about the properties of the control object and limited access to the measuring information about its state, which are typical for many technical applications. Motive and search for control laws in the mentioned class of systems are obvious.

International Programmers’ Day was last week; today we give a special shout-out to those programmers who developed the apps that allow companies to communicate easily and provide services to clients from around the world.

NTR Lab is one of those companies; we work remotely using multiple technologies to communicate and collaborate with companies in dozens of countries. We also connect with them in person during road trips taken specifically to meet them.

Today we would like to tell more about life of our software development company and present the most popular and interesting stuff happened recently. We prepared list post with our TOPs.

Our company loves company events. We have regular monthly pizza parties to celebrate colleagues’ birthdays, guitar playing parties, as well as others kinds of entertainment, such as visiting an extreme park, going to restaurants, etc.

No matter the event, the most important thing is that we do it together. It is typical for us to create a spreadsheet and discuss organizational issues for a forthcoming event.

This summer we also had some outdoors gatherings. Two of the most recent ones were held in Moscow, for our headquarters staff, and the other in Tomsk, for the development staff.

Blockchain technology continues to develop rapidly both in Russia and the worldwide. According to some recruiting agencies, the demand for blockchain specialists in just the Russian Federation has grown 40 times over the past six months.

There have been conducted about 10 hackathons for blockhain solutions in Russia over the past year. Many large Russian banks, such as Sberbank, Alfa Bank, Otkritie Bank, RosEvroBank, continue pilot projects to implement blockchain in their business processes and some have already switched its to commercial operations.

Artificial Intelligence Amongst Various Industries

We met BPU Holdings at AI Expo Europe and invited them to share a post on our blog. We think you will enjoy it.

By Oh SangGyoon, CEO BPU Holdings

Today, Artificial Intelligence (AI) has been widely accepted in our consumer products and is becoming well-adapted into daily communication styles. The more educated individuals become on the technology, the better we understand and accept that AI is not a viable threat to our lives or our jobs – as Hollywood movies portray. It becomes apparent that AI taps into many different industries other than technology. Here are a few applications amongst various industries and audiences that AI is advancing:

1. ZimGo Polling – In the 2016 US Presidential election, pollsters were baffled by the winning results of Trump versus Clinton. In fact, our ZimGo Polling political forecasting tool predicted Trump’s win, way in advance. Introduced in 2017, ZimGo Polling is a state-of-the-art technology that uses Artificial Emotional Intelligence (AEI) and sentiment analysis, NLP, and machine learning to pioneer results in political forecasting. In 2017, it was applied in the South Korean Presidential elections and proved that our forecast ranking was the fastest amongst competitors with only a 2% margin of error.

From AI (thinking) to AEI (feeling)

08/10/2018education articles#AEI, #AI, #Artificial Emotional Intelligence, #Artificial Intelligence, #Behavior, #BPU Holdings, #Computer Vision, #EI, #Emotional Intelligence, #Emotions, #Empathy, #Emulation, #Feelings, #Humanoid robots, #Machine Learning, #Natural Language Processing, #Recognition, #Virtual assistants, #ZimGoDaria

“Emotional intelligence (EI) is the capability of individuals to recognize their own emotions and those of others, discern between different feelings and label them appropriately, use emotional information to guide thinking and behavior, and manage and/or adjust emotions to adapt to environments or achieve one’s goal(s).”

— Colman, Andrew (2008). A Dictionary of Psychology (3 ed.). Oxford University Press. (source: Wikipedia)

Major strides have been made creating Artificial Intelligence (AI). Machines embedded with AI can do a lot, but they lack what is inherent in people — Emotional Intelligence.

Emotional intelligence allows us recognize our own emotions and those of others and use this information to guide our thinking and behavior. Moving from AI to AEI is a work in progress.
