University researchers in Swansea have trained computers to detect cancer cells using artificial intelligence algorithms. Using similar technology to face and fingerprint recognition software, the computers have been taught to recognise cells and pinpoint them. It means cancer cells can be identified quicker, speeding up diagnosis times. The project is in collaboration with specialists in the US, Germany, London and Newcastle. Prof Paul Rees, from the university's college of engineering, said in the past, finding cancer cells had been like "looking for a needle in a haystack" and the new method was a "world-leading development".

The comparison is performed on a data set where linear regression works well: salary offered to a candidate, based on programming language requirements in the job ad: Python, R or SQL. This is a follow-up to the article highest paying programming skills. The increased accuracy of linear regression estimates is negligible, and well below the noise level present in the data set. The Jackknife method has the advantage to be more stable, easy to code, easy to understand (no need to know matrix algebra), and easy to interpret (meaningful coefficients). Jackknife is not the first regression approximation developed by the author: check my book pages 172-176 for other examples.

Artificial intelligence and its machine learning subset are all the rage these days. That was evident when I spoke this week at the AI World event, which was packed with vendors and users seeking to understand what the hell AI and machine learning are--and wanting to know how they could use this old but revitalized technology effectively. Amazon Web Services, Google, IBM, Microsoft, and the other major cloud providers all have machine learning services in their clouds now. But most enterprises have no clue on what the heck to do with machine learning systems, whether cloud or on-premises. It is critical to find the right uses for machine learning.

Armin Prommersberger is senior vice president, Technology -- Lifestyle Audio Division, HARMAN International. How to join the network Today's competitive business world demands innovation. Corporations need to innovate to inspire, compete and survive. However, the burden of innovation has largely rested on startups. Large corporations and established businesses are expected to out-think their rivals, but more often we see that they rely on minor product updates or acquisitions in place of home-grown innovation. Startups are moving too fast these days for a complacent strategy to be enough. No longer can companies and business leaders rely on slow-moving corporate or product strategies to withstand the attack from disruptive upstarts.

The way a message is communicated is almost as important as the message itself. Our world is moving towards a more data-oriented approach to decision making in every walk of life. Packaging the analysis in a way that's easy to digest can increase its reach and effectiveness. Humans have evolved to develop a very acute sense of pattern recognition. Using storytelling by representing your data through various graphical and pictorial tools gives the audience an intuitive grasp of the matter, enabling them to easily process and digest the information.

Use in transforming unstructured data into structured especially in social media monitoring, business intelligence, content recommendations, financial trading and targeted advertising. A live mashup that consumes Alina demonstrates the API's ability to use genetic algorithms and artificial neural networks to analyze historical Bitcoin price fluctuations to predict and automate future trading. Amazon Machine Learning: To find patterns in data. Example uses of this API are applications for fraud detection, forecasting demand, targeted marketing, and click prediction BigML: BigML is a service for cloud-hosted machine learning and data analysis. Users can set up a data source, create a dataset, create a model from the dataset, and then make predictions based on the data.

Why'Deep Learning' is called deep? It is because of the structure of ANNs. Earlier 40 years back, neural networks were only 2 layers deep as it was not computationally feasible to build larger networks. Now it is common to have neural networks with 10 layers and even 100 layer ANNs are being tried upon. Using multiple levels of neural networks in Deep Learning, computers now have the capacity to see, learn, and react to complex situations as well or better than humans. Normally data scientists spend lot of time in data preparation – feature extraction or selecting variables which are actually useful to predictive analytics . Deep learning does this job automatically and make life easier.

Today's hot topic: Resume screening using artificial intelligence Problem: 75% - 88% of resumes received are unqualified Solution: Artificial intelligence that auto-screens thousands of resumes in minutes Results: Candidates are screened with near perfect accuracy and presented to the hiring manager in order of interview priority Outcome: This technology will free up time so talent acquisition can focus on what is most important: interviewing and building their best teams www.Ideal.com Ideal builds software that Talent Acquisition loves. Ideal uses artificial intelligence to help make precise and efficient high-volume hiring decisions. Companies use Ideal's Intelligent Screening technology to sift through the resume noise and instantly identify who to interview.

The presidential campaign made clear that chauvinist attitudes toward women remain stubbornly fixed in some parts of society. It turns out we're inadvertently teaching artificial-intelligence systems to be sexist, too. New research shows that subtle gender bias is entrenched in the data sets used to teach language skills to AI programs. As these systems become more capable and widespread, their sexist point of view could have negative consequences--in job searches, for instance. The problem results from the way machines are being taught to read and talk.
