Reseachers benchmarked 22 classification methods that automatically assign cell identities including single-cell-specific and general-purpose classifiers. The performance of the methods is evaluated using 27 publicly available single-cell RNA sequencing datasets of different sizes, technologies, species, and levels of complexity. The general-purpose support vector machine classifier has overall the best performance across the different experiments. Researchers present a novel algorithm for predicting genetic ancestry using only variables that are routinely captured in electronic health records (EHRs), such as self-reported race and ethnicity, and condition billing codes. Using patients that have both genetic and clinical information at Columbia University / New York-Presbyterian Irving Medical Center, they developed a pipeline that uses only clinical data to predict the genetic ancestry of all patients of which more than 80% identify as other or unknown.


MUSIC CLASSIFICATION USING ARTIFICIAL INTELLIGENCE

#artificialintelligence

Music is the most popular art form that is performed and listened to by billions of people every day. There are many genres of music such as pop, classical, jazz, folk etc. Each genre has different music instruments, tone, rhythm, beats, flow etc. Digital music and online streaming have become very popular these days due to the increase in the number of users. To create a machine learning model, which classifies music samples into different genres.


Machine Learning Helps Diagnose Patients with Head and Neck Cancers

#artificialintelligence

Under the microscope, both squamous cell carcinoma of the lung and squamous cell carcinoma of the head and neck appear as dense cell groups with non-specific growth patterns, making them impossible to distinguish based on tissue microstructure. But using artificial intelligence (AI), researchers developed a new classification method which identified the primary origins of cancerous tissue based on chemical DNA changes. The neural network achieved an accuracy over 99% when distinguishing between lung cancer and head and neck cancer, according to the findings of a study published in the journal Science Translational Medicine. "The bottom line is that we are solving a highly clinically relevant diagnostic problem by combining DNA-methylation profiling and AI and deep neural networks and got 99% accuracy," Klauschen said in a statement to Inside Digital Health . "Before our method, this was more less guess work."


Denis Magda on Continuous Deep Learning with Apache Ignite

#artificialintelligence

At the recent ApacheCon North America, Denis Magda spoke on continuous machine learning with Apache Ignite, an in-memory data grid. Ignite simplifies the machine-learning pipeline by performing training and hosting models in the same cluster that stores the data, and can perform "online" training to incrementally improve models when new data is available. Magda, vice-president of product management at GridGain, began by describing some of the pain points of machine learning on large datasets, in particular the latency involved in moving data across the network from its storage location to the processors that perform training. Models also have to be deployed into a production system after they are trained, and retrained periodically after new data is collected. Because Ignite runs code on the same computers that host data, it can train, deploy, and update a machine-learning model without a time-consuming extract-transform-load (ETL) step.

Many Heads Are Better Than One: The Case For Ensemble Learning

#artificialintelligence

"The interests of truth require a diversity of opinions." Banks and lenders are increasingly turning to AI and machine learning to automate their core functions and make more accurate predictions in credit underwriting and fraud detection. ML practitioners can take advantage of a growing number of modeling algorithms, such as simple decision trees, random forests, gradient boosting machines, deep neural networks, and support vector machines. Each method has its strengths and weaknesses, which is why it often makes sense to combine ML algorithms to provide even greater predictive performance than any single ML method could provide on its own. This method of combining algorithms is known as ensembling.


Körber Prize 2019 for Bernhard Schölkopf

#artificialintelligence

Bernhard Scholkopf, director of the Max Planck Institute for Intelligent Systems in Tbingen, Germany, has been honored with the Korber Prize for European Science 2019. Bernhard Schölkopf, director at the Max Planck Institute for Intelligent Systems in Tübingen, Germany, is honored with the Körber Prize for European Science 2019. The Körber Foundation awards the prize to honor the computer scientist's contributions to machine learning, which today supplies one of the most important methods of Artificial Intelligence (AI). The Körber Prize includes prize money of one million Euros. Artificial Intelligence opens up new opportunities in ever more areas of day-to-day life: "AI is in play when a smartphone group stores photos according to faces and topics such as holidays," Schölkopf explains.


3 Python Tools Data Scientists Can Use for Production-Quality Code

#artificialintelligence

For many of these steps, there are no real short cuts to be taken. The only way to build a minimum viable product, for example, is to roll up your sleeves and start coding. However, in a few cases, tools exist to automate tedious manual processes and make your life much easier. In Python, this is the situation for steps 4, 8 and 10, thanks to the unittest, flake8 and sphinx packages. Let's look at each of these packages one by one.


Adversarial Robustness 360 Toolbox v1.0: A Milestone in AI Security

#artificialintelligence

Next week at AI Research Week, hosted by the MIT-IBM Watson AI Lab in Cambridge, MA, we will publish the first major release of the Adversarial Robustness 360 Toolbox (ART). Initially released in April 2018, ART is an open-source library for adversarial machine learning that provides researchers and developers with state-of-the-art tools to defend and verify AI models against adversarial attacks. ART v1.0 marks a milestone in AI security, introducing new features that extend ART to conventional machine learning models and a variety of data types beyond images: The number of reports on real-world exploitations using adversarial attacks against AI is growing, as in the case of anti-virus software, highlighting the importance of understanding, improving and monitoring the adversarial robustness of AI models. ART provides a comprehensive and growing set of tools to systematically assess and improve the robustness of AI models against adversarial attacks, including evasion and poisoning. In evasion attacks, the adversary crafts small changes to the original input to an AI model in order to influence its behaviour.


Using Machine Learning In Venture Capital

#artificialintelligence

After the last financial crisis, the interest rates decreased exponentially and venture capital suddenly became an attractive option to achieve high returns. However, in only a decade the market moved so fast, got so mature and saturated, and so many empires have been created, that is now cumbersome to obtain sustainable returns investing in risky early-stage companies. In fact, capital is abundant nowadays and funds have been raised everywhere, while there is no scarcity either in companies of every shape and size. For these reasons, investing has become incredibly competitive and it has never been harder to spot the needle in the haystack that would make you rich. Unfortunately, the toolbox investors currently have available is not robust enough to reduce their risk and help them managing uncertainty in a better way. This is where machine learning can come to aid.
