Analysis and Mortality Prediction using Multiclass Classification for Older Adults with Type 2 Diabetes
Desure, Ruchika, Krishna, Gutha Jaya
Designing proper treatment plans to manage diabetes requires health practitioners to pay heed to the individuals remaining life along with the comorbidities affecting them. Older adults with Type 2 Diabetes Mellitus (T2DM) are prone to experience premature death or even hypoglycaemia. The structured dataset utilized has 68 potential mortality predictors for 275,190 diabetic U.S. military Veterans aged 65 years or older. A new target variable is invented by combining the two original target variables. Outliers are handled by discretizing the continuous variables. Categorical variables have been dummy encoded. Class balancing is achieved by random under-sampling. A benchmark regression model is built using Multinomial Logistic Regression with LASSO. Chi-Squared and Information Gain are the filter-based feature selection techniques utilized. Classifiers such as Multinomial Logistic Regression, Random Forest, Extreme Gradient Boosting (XGBoost), and One-vs-Rest classifier are employed to build various models. Contrary to expectations, all the models have constantly underperformed. XGBoost has given the highest accuracy of 53.03 percent with Chi-Squared feature selection. All the models have consistently shown an acceptable performance for Class 3 (remaining life is more than 10 years), significantly low for Class 1 (remaining life is up to 5 years), and the worst for Class 2 (remaining life is more than 5 but up to 10 years). Features analysis has deduced that almost all input variables are associated with multiple target classes. The high dimensionality of the input data after dummy encoding seems to have confused the models, leading to misclassifications. The approach taken in this study is ineffective in producing a high-performing predictive model but lays a foundation as this problem has never been viewed from a multiclass classification perspective.
Temporal Subtyping of Alzheimer's Disease Using Medical Conditions Preceding Alzheimer's Disease Onset in Electronic Health Records
He, Zhe, Tian, Shubo, Erdengasileng, Arslan, Charness, Neil, Bian, Jiang
Subtyping of Alzheimer's disease (AD) can facilitate diagnosis, treatment, prognosis and disease management. It can also support the testing of new prevention and treatment strategies through clinical trials. In this study, we employed spectral clustering to cluster 29,922 AD patients in the OneFlorida Data Trust using their longitudinal EHR data of diagnosis and conditions into four subtypes. In addition, according to the results of various statistical tests, these subtypes are also significantly different with respect to demographics, mortality, and prescription medications after the AD diagnosis. This study could potentially facilitate early detection and personalized treatment of AD as well as data-driven generalizability assessment of clinical trials for AD. Introduction Alzheimer's disease (AD) is a progressive neurodegenerative disorder that affects an estimated 6.2 million Americans age 65 and older in 2021. This number is likely to reach 13.8 million by 2060.
Julia: a Language for the Future of Cybersecurity
Julia is a comparably new language that aimed to have the performance of C and simplicity of Python. Having the ability to perform data analysis without much trouble while shipping the code with competitive performance, Julia is expected to be a powerful tool in FinTech businesses. But I think it also have some great potentials regarding to the current trends in Cybersecurity. In this article, I will explain why Julia can also be a great tool for the future of Cybersecurity. Meanwhile, I will share how I wrote a Julia script on my Mac computer to crack a cipher text encrypted with Caesar Code Shift and Columnar Transposition.
REPORT: Top 10 AI Jobs, Salaries and Cities - Indeed Blog
While we don't yet have the personal androids promised to us in sci-fi movies, artificial intelligence (AI) is increasingly a part of our everyday lives, with Forbes declaring 2019 "the year AI will move into the mainstream." Thanks to AI, you can use your smartphone to deposit checks. And AI makes recommendations on Amazon and Netflix based on your usage and preferences. With AI becoming more deeply integrated into our professional and personal lives, the Indeed analytics team crunched platform data to learn more about AI jobs in 2019. What are the top positions?
The 10 most in-demand AI jobs of 2019
Postings for jobs in artificial intelligence (AI) rose 29% in the last year, from May 2018 to May 2019, according to new data from job search site Indeed. However, this represents a significant decrease from years past: From May 2017 to May 2018, AI job postings on the site grew nearly 58%, and from May 2016 to May 2017, they grew 136%. Job seeker interest in AI-related positions is also beginning to slow, Indeed researchers noted in a Friday blog post: Searches for AI-related jobs on Indeed decreased by nearly 15% in the last year, while they had increased 32% and 49% the previous two years. The drop suggests there may be more open jobs than there are qualified employees to fill them, the post noted. SEE: Artificial intelligence: A business leader's guide (free PDF) (TechRepublic) In terms of most in-demand AI jobs, the following 10 positions had the highest percentage of job descriptions that included the keywords "artificial intelligence" or "machine learning," according to Indeed: While machine learning engineers had the highest percentage of AI and machine learning keyboards both this year and last year, several of these in-demand roles were not found on the 2018 list, the post noted.
Indeed: AI job-posting rate slows and interest dips
Artificial intelligence jobs have been hot in Silicon Valley and elsewhere, with a machine-learning engineer getting an average salary of $142,858 a year. But AI job-posting growth has slowed, and interest in these jobs is also dipping, according to a study by job site Indeed. AI job postings on Indeed rose 29.1% from May 2018 to May 2019. However, that increase is substantially less than it was the previous two years. During the same time period -- May 2017 to May 2018 -- AI job postings on Indeed rose 57.9%, and a whopping 136.2% between May 2016 and May 2017.
Can AI in healthcare help us identify high-risk people across systems?
Many of the buzzy applications of AI in healthcare we hear about involve medical IoT, computer vision for radiology or disease prediction. But the fact is, many health institutions that just aren't there yet with adoption. With limited budgets and dated systems, can public health agencies tap into the power of AI? Yes! And they don't need a massive technology infrastructure to start. There are many promising areas for the application of AI in healthcare and life sciences.
Are Manufacturers Ready for the Connected Industrial Workforce?
Despite plans to invest in machines and artificial intelligence as part of their strategy to boost productivity, many automotive and industrial equipment companies are failing to implement the measures needed to harness these capabilities, according to a new report from Accenture. The report, "Machine dreams: Making the Most of the Connected Industrial Workforce," is based on interviews with more than 500 business executives in Asia, Europe and the United States involved in setting their company's strategy for the connected industrial workforce. According to the report, manufacturing and production are undergoing rapid change as machines and AI are becoming closely integrated with personnel, creating the connected industrial workforce. By combining mobile, safety and tracking technologies with analytics, companies are enhancing the activities of an industrial worker. The report concludes that the creation of a connected industrial workforce is already part of the business strategy of the majority of automotive and industrial equipment producers, cited by 94 percent of respondents.
