Lamenesses are frequently characterized by asymmetric limb motion, Bragança said. Strapped to different sections of a horse's body, inertial measurement units (IMUs) are becoming useful tools for evaluating asymmetry and body lean angles. Dutch and Belgian scientists are now looking at ways to gather reliable movement data from IMUs placed on horses' limbs, head, body, and pelvis. And this, they say, can lead to even greater accuracy in both veterinary diagnoses and performance evaluations. "It is important that we have methods to objectively quantify and record limb motion since we are now, more and more, aware of the limitations of the human eye as an instrument to detect motion asymmetries, especially at high speeds," said Filipe Serra Bragança, DVM, a PhD candidate in equine musculoskeletal biology at Utrecht University's Faculty of Veterinary Medicine Department of Equine Sciences, in The Netherlands.

Improving the precision of heart diseases detection has been investigated by many researchers in the literature. Such improvement induced by the overwhelming health care expenditures and erroneous diagnosis. As a result, various methodologies have been proposed to analyze the disease factors aiming to decrease the physicians practice variation and reduce medical costs and errors. In this paper, our main motivation is to develop an effective intelligent medical decision support system based on data mining techniques. In this context, five data mining classifying algorithms, with large datasets, have been utilized to assess and analyze the risk factors statistically related to heart diseases in order to compare the performance of the implemented classifiers (e.g., Na\"ive Bayes, Decision Tree, Discriminant, Random Forest, and Support Vector Machine). To underscore the practical viability of our approach, the selected classifiers have been implemented using MATLAB tool with two datasets. Results of the conducted experiments showed that all classification algorithms are predictive and can give relatively correct answer. However, the decision tree outperforms other classifiers with an accuracy rate of 99.0% followed by Random forest. That is the case because both of them have relatively same mechanism but the Random forest can build ensemble of decision tree. Although ensemble learning has been proved to produce superior results, but in our case the decision tree has outperformed its ensemble version.

AI applications have been deployed and used for industrial, government, and consumer purposes for many years. The experiences have been documented in IAAI conference proceedings since 1989. Over the years, the breadth of applications has expanded many times over and AI systems have become more commonplace. Indeed, AI has recently become a focal point in the industrial and consumer consciousness. This article focuses on changes in the world of computing over the last three decades that made building AI applications more feasible. We then examine lessons learned during this time and distill these lessons into succinct advice for future application builders.

One evening last November, a fifty-four-year-old woman from the Bronx arrived at the emergency room at Columbia University's medical center with a grinding headache. Her vision had become blurry, she told the E.R. doctors, and her left hand felt numb and weak. The doctors examined her and ordered a CT scan of her head. A few months later, on a morning this January, a team of four radiologists-in-training huddled in front of a computer in a third-floor room of the hospital. The room was windowless and dark, aside from the light from the screen, which looked as if it had been filtered through seawater. The residents filled a cubicle, and Angela Lignelli-Dipple, the chief of neuroradiology at Columbia, stood behind them with a pencil and pad. She was training them to read CT scans. "It's easy to diagnose a stroke once the brain is dead and gray," she said. "The trick is to diagnose the stroke before too many nerve cells begin to die." Strokes are usually caused by blockages or bleeds, and a neuroradiologist has about a forty-five-minute window to make a diagnosis, so that doctors might be able to intervene--to dissolve a growing clot, say. "Imagine you are in the E.R.," Lignelli-Dipple continued, raising the ante. "Every minute that passes, some part of the brain is dying. Time lost is brain lost." She glanced at a clock on the wall, as the seconds ticked by. "So where's the problem?" she asked. The blood supply to the brain branches left and right and then breaks into rivulets and tributaries on each side. A clot or a bleed usually affects only one of these branches, leading to a one-sided deficit in a part of the brain. As the nerve cells lose their blood supply and die, the tissue swells subtly.

Detecting cancer sooner rather than later can help prevent worst outcomes in many cases. Yet diagnosing different types of cancers in their earliest stages is not often possible. It requires years of training to gain the expertise and experience to do well in detecting cancerous tumor. Even with extensive training, some symptoms may be hard to distinguish from the signs of other similar diseases. For example, agreement in diagnosis for some forms of breast cancer can be as low as 48% and this percentage of disagreement is not surprising given the massive amount of information needed to review in order to make an accurate diagnoses and often within a limited time. To overcome these issues, Google researchers have developed an automated detection algorithm that is effective at identifying breast cancer.

Amazon.com (AMZN) on Thursday blamed human error for an outage at its cloud-services unit that caused widespread disruption to internet traffic across the U.S. earlier this week. In a post on its website, Amazon said the outage started with a typo at Amazon's North Virginia data centers Tuesday. An employee trying to speed up the company's S3 cloud-storage billing system tried to take a few servers offline. The employee mistyped the command, however, affecting more servers than intended, which led to a cascade of failures that ultimately knocked out S3 and other Amazon services. It also took longer than expected to restart certain services, Amazon said.

Words may literally have the power to heal now. An Israeli company by the name of Beyond Verbal is launching a platform solely committed to analyzing emotions from vocal intonations. The Beyond Health Research platform is paving its way into the world of healthcare by identifying the distinctive vocal features that are, in every way, imperceptible to humans, and are referred to as vocal "biomarkers". These vocal biomarkers can serve as a diagnostic tool for your physician to indicate signs of illnesses ranging from stress and depression to cardiovascular diseases. An earlier diagnosis could essentially be the difference between life and death. This breakthrough is being backed up by 21 years of thorough research encompassing over 2.5 million emotion-labeled voices in over 40 different languages.

The last post in the Machine Learning algorithm frenzy that I'm currently on was based on Support Vector Machines. This post is going to look at another classification algorithm called a Decision Tree and again see if this can improve on our classification problem of predicting whether lines from Simpson's episodes are said by Bart or Homer. Again, a Decision Tree is a supervised learning algorithm that can be used to classify data based on a model it has built on training data. Like the other models, it tries to split data into two or more sets but the most significant variable that creates the best split is calculated by the algorithm. To distinguish between Homer and Bart from a set of images the decision tree would split the data on each of them and choose which performs best.

A decision tree is one of the widely used algorithms for building classification or regression models in data mining and machine learning. A decision tree is so named because the output resulting from it is the form of a tree structure. Consider a sample stock dataset as shown in the table below. The dataset comprises of Open, High, Low, Close Prices and Volume indicators (OHLCV) for the stock. Let us add some technical indicators (RSI, SMA, LMA, ADX) to this dataset.
