A Multilevel Coordinate Search Algorithm for Well Placement, Control and Joint Optimization

arXiv.org Artificial Intelligence

Determining optimal well placements and controls are two important tasks in oil field development. These problems are computationally expensive, nonconvex, and contain multiple optima. The practical solution of these problems require efficient and robust algorithms. In this paper, the multilevel coordinate search (MCS) algorithm is applied for well placement and control optimization problems. MCS is a derivative-free algorithm that combines global and local search. Both synthetic and real oil fields are considered. The performance of MCS is compared to generalized pattern search (GPS), particle swarm optimization (PSO), and covariance matrix adaptive evolution strategy (CMA-ES) algorithms. Results show that the MCS algorithm is strongly competitive, and outperforms for the joint optimization problem and with a limited computational budget. The effect of parameter settings for MCS are compared for the test examples. For the joint optimization problem we compare the performance of the simultaneous and sequential procedures and show the utility of the latter.


Turing Learning breakthrough: Computers can now learn from pure observationTrue Viral News

#artificialintelligence

An exciting new study from the University of Sheffield and published in the journal Swarm Intelligence has demonstrated (free pre-print version) a method of allowing computers to make sense of complex patterns all on their own, an ability that could open the door to some of the most advanced and speculative applications of artificial intelligence. Using an all-new technique called Turing Learning, the team managed to get an artificial intelligence to watch movements within a swarm of simple robots and figure out the rules that govern their behavior. It was not told to look for any particular signifier of swarm behavior, but simply to try to emulate the source more and more accurately and to learn from the results of that process. It's a simple system that the researchers think could be applied everywhere from human and animal behavior to biochemical analysis to personal security. Alan Turing was a multi-talented British mathematician who helped to both win the Second World War and invent the earliest computers, both while leading the Allied code-breaking efforts at Blechley Park.


A Review of Machine Learning Algorithms and Applications

#artificialintelligence

With the explosion of data generation, getting optimal solutions to data driven problems is increasingly becoming a challenge, if not impossible.The importance of machine learning algorithms, which can handle this burst of data and assist in intelligent decision making, is thus realised among data scientists. Within this category of machine learning algorithms, a special focus area is bio-inspired algorithms. This review article provides the readers some inputs on the advances in the domain of bio inspired algorithms and their potential applications across domains. It is increasingly being recognised that applications of intelligent bio-inspired algorithms are necessary for addressing highly complex problems to provide working solutions in time, especially with dynamic problem definitions, fluctuations in constraints, incomplete or imperfect information and limited computation capacity. More and more such intelligent algorithms are thus being explored for solving different complex problems. While some studies are exploring the application of these algorithms in a novel context, other studies are incrementally improving the algorithm itself.

Christian drama 'Natural Selection' is no subtle offering

Los Angeles Times

There's little that comes off as "natural" in "Natural Selection," a stiffly heavy-handed, drawn-out, faith-based drama about a Christ-like teen struggling to find his true path. Arriving in a new town, soft-spoken Tyler (Mason Dye) and his alcoholic mother ("Bluebloods" regular Amy Carlson) have chosen the proverbial fresh start, but there are telling signs that it won't be a smooth transition. Tyler is immediately targeted by the bullies at his new high school, which, curiously, doesn't appear to have a single character of color among the student body, while his mom is finding it difficult to extricate herself from the throes of depression in the wake of her husband's suicide. He's taken under the manipulative wing of the troubled Indrid (Ryan Munzert), an outsider with a dark soul (how else to explain his non-creationist views?) who chastises Tyler for having too much faith in people. You know from the repeated close-ups of all those guns mounted in the display cabinet at Indrid's home that his profound disenchantment with the universe isn't going to end well, but first-time writer-director Chad Scheifele forcefully prolongs the inevitable.


Social and Business Intelligence Analysis Using PSO

arXiv.org Artificial Intelligence

The goal of this paper is to elaborate swarm intelligence for business intelligence decision making and the business rules management improvement. .The swarm optimization, which is highly influenced by the behavior of creature, performs in group. The Spatial data is defined as data that is represented by 2D or 3D images. SQL Server supports only 2D images till now. As we know that location is an essential part of any organizational data as well as business data enterprises maintain customer address lists, own property, ship goods from and to warehouses, manage transport flows among their workforce, and perform many other activities. By means to say a lot of spatial data is used and processed by enterprises, organizations and other bodies in order to make the things more visible and self descriptive. From the experiments, we found that PSO is can facilitate the intelligence in social and business behavior.


Single-shot Adaptive Measurement for Quantum-enhanced Metrology

arXiv.org Machine Learning

Quantum-enhanced metrology aims to estimate an unknown parameter such that the precision scales better than the shot-noise bound. Single-shot adaptive quantum-enhanced metrology (AQEM) is a promising approach that uses feedback to tweak the quantum process according to previous measurement outcomes. Techniques and formalism for the adaptive case are quite different from the usual non-adaptive quantum metrology approach due to the causal relationship between measurements and outcomes. We construct a formal framework for AQEM by modeling the procedure as a decision-making process, and we derive the imprecision and the Cram\'{e}r-Rao lower bound with explicit dependence on the feedback policy. We also explain the reinforcement learning approach for generating quantum control policies, which is adopted due to the optimal policy being non-trivial to devise. Applying a learning algorithm based on differential evolution enables us to attain imprecision for adaptive interferometric phase estimation, which turns out to be SQL when non-entangled particles are used in the scheme.

Consider TPOT your Data Science Assistant. TPOT is a Python tool that automatically creates and optimizes machine learning pipelines using genetic programming. TPOT will automate the most tedious part of machine learning by intelligently exploring thousands of possible pipelines to find the best one for your data. Once TPOT is finished searching (or you get tired of waiting), it provides you with the Python code for the best pipeline it found so you can tinker with the pipeline from there. TPOT is built on top of scikit-learn, so all of the code it generates should look familiar... if you're familiar with scikit-learn, anyway.


What If Intelligent Machines Could Learn From Each Other?

#artificialintelligence

Take a look around and you'll see evidence of the widespread adoption of wearable sensors for health and fitness, such as the Fitbit, Garmin or other devices. What many people may not know is that we are also using sensors to monitor the structural integrity of bridges and buildings, as well as tracking the movements of insects and other animals. With the rapid growth of the Internet of Things (IoT), tens of billions of sensor devices are projected to connect in the next decade. These connected sensor devices will automate processes across a broad range of economic sectors, from industrial plants to healthcare management, delivering productivity gains and hopefully quality-of-life improvements. The core of these sensor devices that will be deployed across this broad range of applications is largely the same, featuring a microprocessor, memory and a wired or wireless communication interface to the internet, along with a battery or other energy source.
