Creating Heatmaps and Clustering in R

#artificialintelligence

In the R code above, the bluered() function [in gplots package] is used to generate a smoothly varying New What you'll learn to create colorful heatmaps showing the relationship between species and also gene expression levels between samples how to cluster species/genes in the data sets Requirements Description In this video the student will be able to use clustering methods to find clusters in his data. He will also be able to make nice-looking heatmaps using the heatmap and the pheatmap command. Clustering topics such as k-means clustering, PAM clustering, Silhouette plots, and elbow plots will be covered. Minimal familiarity with R coding is required. In this video the student will be able to use clustering methods to find clusters in his data.


Ensemble Methods: A Beginner's Guide

#artificialintelligence

When I started my Data Science journey,few terms like ensemble,boosting often popped up.Whenever I opened the discussion forum of any Kaggle Competition or looked at any winner's solution,it was mostly filled with these things. At first these discussions sounded totally alien,and these class of ensemble models looked like some fancy stuff not meant for the newbies,but trust me once you have a basic understanding behind the concepts you are going to love them! So let's start with a very simple question,What exactly is ensemble? "A group of separate things/people that contribute to a coordinated whole" In a way this is kind of the core idea behind the entire class of ensemble learning! Well let's rewind the clocks a bit and go back to the school days for a while, remember you used to get a report card with an overall grade.Well how exactly was this overall grade calculated,your teachers of respective subjects gave some feedback based on their set of criteria,for example your math teacher would assess you on his own criteria like algebra,trigonometry etc, sports teacher would judge you how you perform on the field,your music teacher would judge on you vocal skills.Point being each of these teachers have their own set of rules of judging the performance of a student and later all of these are combined to give an overall grade on the performance of the student.


PhD student: Differential Privacy for Machine Learning and Fairness M/F Job

#artificialintelligence

SAP started in 1972 as a team of five colleagues with a desire to do something new. Together, they changed enterprise software and reinvented how business was done. Today, as a market leader in enterprise application software, we remain true to our roots. That's why we engineer solutions to fuel innovation, foster equality and spread opportunity for our employees and customers across borders and cultures. SAP values the entrepreneurial spirit, fostering creativity and building lasting relationships with our employees.


Code-free machine learning: AutoML with AutoGluon, Amazon SageMaker, and AWS Lambda

#artificialintelligence

One of AWS's goals is to put machine learning (ML) in the hands of every developer. With the open-source AutoML library AutoGluon, deployed using Amazon SageMaker and AWS Lambda, we can take this a step further, putting ML in the hands of anyone who wants to make predictions based on data--no prior programming or data science expertise required. AutoGluon automates ML for real-world applications involving image, text, and tabular datasets. AutoGluon trains multiple ML models to predict a particular feature value (the target value) based on the values of other features for a given observation. During training, the models learn by comparing their predicted target values to the actual target values available in the training data, using appropriate algorithms to improve their predictions accordingly.


Why you should learn Computer Vision and how you can get started

#artificialintelligence

In today's world, Computer Vision technologies are everywhere. They are embedded within many of the tools and applications that we use on a daily basis. However, we often pay little attention to those underlaying Computer Vision technologies because they tend to run in the background. As a result, only a small fraction of those outside the tech industries know about the importance of those technologies. Therefore, the goal of this article is to provide an overview of Computer Vision to those with little to no knowledge about the field. I attempt to achieve this goal by answering three questions: What is Computer Vision?, Why should you learn Computer Vision? and How you can get started?


Why Did AI Fall Short In Slowing The Spread Of COVID-19?

#artificialintelligence

The healthcare industry hoped that AI would play a crucial tool in curbing the spread of the COVID-19 virus across the world. The results up till now are a letdown. Dr Isaac Kohane (Department of Biomedical Informatics at Harvard Medical School) states that in a few cases, they were anti-constructive. He even states that they were shooting for the moon in healthcare, but they weren't even out of their own backyard. He felt that weren't getting anywhere due to the lack of high-grade data. Yet faith isn't lost on the AI contribution to address the pandemic.


GPT-3 Creative Fiction

What if I told a story here, how would that story start?" Thus, the summarization prompt: "My second grader asked me what this passage means: …" When a given prompt isn't working and GPT-3 keeps pivoting into other modes of completion, that may mean that one hasn't constrained it enough by imitating a correct output, and one needs to go further; writing the first few words or sentence of the target output may be necessary.


What do medical students actually need to know about artificial intelligence?

#artificialintelligence

With emerging innovations in artificial intelligence (AI) poised to substantially impact medical practice, interest in training current and future physicians about the technology is growing. Alongside comes the question of what, precisely, should medical students be taught. While competencies for the clinical usage of AI are broadly similar to those for any other novel technology, there are qualitative differences of critical importance to concerns regarding explainability, health equity, and data security. Drawing on experiences at the University of Toronto Faculty of Medicine and MIT Critical Data’s “datathons”, the authors advocate for a dual-focused approach: combining robust data science-focused additions to baseline health research curricula and extracurricular programs to cultivate leadership in this space.


Examining Undergraduate Computer Science Participation in North Carolina

Communications of the ACM

Former U.S. President Obama put forth the initiative'CSForAll' in order to prepare all students to learn computer science (CS) skills and be prepared for the digital economy. The'ForAll' portion of the title emphasizes the importance of inclusion in computing via the participation and creation of tools by and for diverse populations in order to "avoid the consequences of narrowly focused AI (computing and other) applications, including the risk of biases in developing algorithms, by taking advantage of a broader spectrum of experience, backgrounds, and opinions."10 Throughout this report, the Obama administration highlighted the number one priority, and challenge, of the field of CS: to equip the next generation with CS knowledge and skills equitably in preparation for the currency of the digital economy. An increase in government funding is part of the initiative for CSForAll. Of the $4 billion pledged in state funding, only $100 million is sent directly to the K–12 school system.17 The rest of the funding is set aside for research and initiatives involving policymakers to help expand CS opportunities. In just one year, the National Science Foundation (NSF) and Corporation for National and Community Service (CNCS) were called to make $135 million in CS funding available.17 The initiative also called for "expanding access to prior NSF supported programs and professional learning communities through their CS10k that led to the creation of more inclusive and accessible CS education curriculum including "Exploring CS and Advanced Placement (AP) CS Principles."

Fully appreciating the overarching scope of CS requires weaving more than ethics into the reigning curricula.
