Job opportunities (The University of Manchester)

@machinelearnbot

This is an exciting opportunity for a researcher at post-doctoral level with experience of machine learning and data mining. You will work with senior data scientists based within the local NHS trusts, the University of Manchester Health eResearch Centre, and Health Innovation Manchester to automate data extraction of predetermined features for all patients diagnosed with ovarian and colorectal cancer in the conurbation. Machine learning tools including neural networks, support vector machines and naïve Bayes algorithms will be refined and tested using the datasets accrued and optimised for clinical practice. Accuracy of prediction will be assessed using predefined criteria. Knowledge of cancer treatment would be useful but is not essential, as the team has extensive expertise in this area.


What is Vector-based machine learning? • /r/MachineLearning

@machinelearnbot

The simplest answer is it classifies things by drawing a line between two groups of data points. From the linked wiki "More formally, a support vector machine constructs a hyperplane or set of hyperplanes in a high- or infinite-dimensional space, which can be used for classification, regression, or other tasks." The hyperplanes being the "lines" and a high dimensional space meaning you track a bunch of types of data about the things you want to classify. Say you want to know how likely it is to rain tomorrow based on what you know today. You could record the temperature, wind speed, humidity, time of the year, number of days since it last rained, etc.

Support Vector Machine has become an extremely popular algorithm. In this post I try to give a simple explanation for how it works and give a few examples using the the Python Scikits libraries. All code is available on Github. I'll have another post on the details of using Scikits and Sklearn. SVM is a supervised machine learning algorithm which can be used for classification or regression problems.


A Rapid Pattern-Recognition Method for Driving Types Using Clustering-Based Support Vector Machines

arXiv.org Machine Learning

To design an intelligent and human-centered control system [1] that adaptively adjusts relevant parameters in time to meet the human driver's needs and to provide a basic control law for the advanced vehicle dynamics control system [2][3] or driver assistance system [4][5], driver behaviors, driving styles or characteristics should be recognized and predicted. For example, to improve vehicle's fuel economy and reduce the emission, we can design different control strategies for driving styles. To achieve these goals, recognition and prediction of driving styles and characteristics precisely is the primary work. Drivers and their factors have been discussed from the viewpoint of application in vehicle dynamics [6][7], physical attributes of human drivers, and modeling driver [8][9]. For the recognition and prediction of driving characteristics or driver types, including physical characteristics/states (e.g., fatigue, drunk, and drowsiness), psychical characteristics (e.g., nervous, relaxed) and driving styles (e.g., aggressive, moderate), a lot of investigations have been conducted in recent years. In general, the basic idea to identify and predict driving behaviors or styles is based on driver model, called indirect or model-based method. The model-based method, firstly, requires to establish a driver model that can describe driver's


Will quantum computing change machine learning?

#artificialintelligence

Then there are'quantum machine learning algorithms,' developed over the last decade following a breakthrough by Harrow, Hassidim, and Lloyd, which do address problems like clustering, classification, support-vector machines, etc. But these algorithms typically require a bunch of conditions to work: for example, that the data are well-conditioned; that they can be accessed in quantum superposition (for example, using a "quantum RAM") or else computed on the fly; and that the properties of the data one cares about can actually be estimated by measuring the resulting quantum states. And we don't yet know how often those conditions will hold in practical applications---and equally important, in the cases where they do hold, we don't have strong evidence that there couldn't be classical random sampling algorithms with similar performance to the quantum algorithms.


Challenge of the week: Piecewise linear clustering versus SVM

@machinelearnbot

In this challenge, we ask you to invent a new technique for clustering, based on separating hyperplanes. SVM (support vector machines) add many fictitious (dummy) variables and a non-linear mapping (to increase dimensionality and find hyperplanes on transformed variables), thus providing nearly or exact class separation (the purpose of clustering!) when traditional linear clustering fails.


Critical Care

#artificialintelligence

Identification of patients with overt cardiorespiratory insufficiency or at high risk of impending cardiorespiratory insufficiency is often difficult outside the venue of directly observed patients in highly staffed areas of the hospital, such as the operating room, intensive care unit (ICU) or emergency department. And even in these care locations, identification of cardiorespiratory insufficiency early or predicting its development beforehand is often challenging. The clinical literature has historically prized early recognition of cardiorespiratory insufficiency and its prompt correction as being valuable at minimizing patient morbidity and mortality while simultaneously reducing healthcare costs. Recent data support the statement that integrated monitoring systems that create derived fused parameters of stability or instability using machine learning algorithms, accurately identify cardiorespiratory insufficiency and can predict their occurrence. In this overview, we describe integrated monitoring systems based on established machine learning analysis using various established tools, including artificial neural networks, k?nearest neighbor, support vector machine, random forest classifier and others on routinely acquired non?invasive and invasive hemodynamic measures to identify cardiorespiratory insufficiency and display them in real?time with a high degree of precision.


Boosting Construction Industry With Artificial Intelligence – AI.Business

#artificialintelligence

Artificial intelligence will be responsible for the next industrial revolution and will change the world in ways we can't predict now. Perhaps you might read our previous articles about influence of AI in agriculture and farming. Construction is an excellent example of industry that will be affected the most from a replacement with automation. AI could save construction businesses money if it becomes smart enough to determine price variants in companies spending for construction materials or hiring engineering companies. We created a list of real use cases that will shape construction industry in near future.


How to choose machine learning algorithms Microsoft Azure

#artificialintelligence

The answer to the question "What machine learning algorithm should I use?" is always "It depends." It depends on the size, quality, and nature of the data. It depends what you want to do with the answer. It depends on how the math of the algorithm was translated into instructions for the computer you are using. And it depends on how much time you have. Even the most experienced data scientists can't tell which algorithm will perform best before trying them. The Microsoft Azure Machine Learning Algorithm Cheat Sheet helps you choose the right machine learning algorithm for your predictive analytics solutions from the Microsoft Azure Machine Learning library of algorithms.


Extreme Learning Machines: Random Neurons, Random Features, Kernels

#artificialintelligence

Unlike conventional learning theories and tenets, our doubts are "Do we really need so many different types of learning algorithms (SVM, BP, etc) for so many different types of networks (different types of SLFNs (RBF networks, polynomial networks, complex networks, Fourier series, wavelet networks, etc) and multi-layer of architecfures, different types of neurons, etc)? Is there a general learning scheme for wide type of different networks (SLFNs and multi-layer networks)? Neural networks (NN) and support vector machines (SVM) play key roles in machine learning and data analysis. Feedforward neural networks and support vector machines are usually considered different learning techniques in computational intelligence community. Both popular learning techniques face some challenging issues such as: intensive human intervene, slow learning speed, poor learning scalability. It is clear that the learning speed of feedforward neural networks including deep learning is in general far slower ...
