Preprocessing for Machine Learning in Python DataCamp
This course covers the basics of how and when to perform data preprocessing. This essential step in any machine learning project is when you get your data ready for modeling. Between importing and cleaning your data and fitting your machine learning model is when preprocessing comes into play. You'll learn how to standardize your data so that it's in the right form for your model, create new features to best leverage the information in your dataset, and select the best features to improve your model fit. Finally, you'll have some practice preprocessing by getting a dataset on UFO sightings ready for modeling.
For These Kids, Turning a Limb Difference Into a Superpower Is a Matter of Tech
Superhero Boost is a weeklong program committed to helping kids reframe a limb difference as an opportunity to create cool prosthetics and other body mods. Sponsored by Google, Autodesk, Born Just Right, and KIDmob, the program is open to kids age 11–17 who have upper-limb differences or who use wheelchairs. The workshop introduces kids to new technologies such as 3D printing, robotics, and artificial intelligence, which the kids use to create their own personal wearable devices designed to release their own inner superheroes. Watch this inspiring video to see what the kids came up with this year.
Building Brains: How Pearson Plans To Automate Education With AI
On a balmy summer's day in San Francisco, Milena Marinova is sitting on the roof terrace of the offices of Pearson, a company in the midst of a radical transformation from publishing powerhouse to digital-education platform, wrapped in a gray shawl and explaining how she plans to build advanced, deep-learning algorithms that could educate the next generation of students. This is no easy task. With millions of students using its education-software, Pearson has amassed "terrabytes" of data from student homework and even textbooks that have been digitized, data that Marinova is now pulling together to build software that can automatically give students feedback on their work like a teacher would. Instead of just telling them that an answer is right or wrong, a future update to Pearson's math homework tool will give more detailed feedback on how they went wrong in the steps taken to get an answer, Marinova told Forbes in an interview. Pearson is starting with math because the topic is relatively easy to structure and digitize.
With 80% salary hikes, Machine Learning and AI is the hottest career right now
When Argho Chatterjee decided to pursue UpGrad and IIIT Bangalore's PG Program in Machine Learning and Artificial Intelligence, he knew he was diving straight into coding his own artificial neural networks, and had a fair idea that this technology could help him solve real-world problems. What came as a pleasant surprise was that he had the access to a personalised learning environment provided by the prestigious institute through its partnership with distinguished online education venture – UpGrad. The two institutes have been working seamlessly to provide learners with an advanced curriculum, projects created in collaboration with the industry experts, and tailor-made support for AI career choices. In fact, the acclaimed degree went on to help Argho make a transition to the role of a Data Scientist ( Deep Learning (AI)) at Samsung R&D with 80% CTC hike! Learning in a personalised environment under great faculty, Argho brushed up on the basics, imbibed conceptual knowledge, and acquired full-fledged knowledge of the field.
A Unified Analysis of Stochastic Momentum Methods for Deep Learning
Yan, Yan, Yang, Tianbao, Li, Zhe, Lin, Qihang, Yang, Yi
Stochastic momentum methods have been widely adopted in training deep neural networks. However, their theoretical analysis of convergence of the training objective and the generalization error for prediction is still under-explored. This paper aims to bridge the gap between practice and theory by analyzing the stochastic gradient (SG) method, and the stochastic momentum methods including two famous variants, i.e., the stochastic heavy-ball (SHB) method and the stochastic variant of Nesterov's accelerated gradient (SNAG) method. We propose a framework that unifies the three variants. We then derive the convergence rates of the norm of gradient for the non-convex optimization problem, and analyze the generalization performance through the uniform stability approach. Particularly, the convergence analysis of the training objective exhibits that SHB and SNAG have no advantage over SG. However, the stability analysis shows that the momentum term can improve the stability of the learned model and hence improve the generalization performance. These theoretical insights verify the common wisdom and are also corroborated by our empirical analysis on deep learning.

Accelerated proximal boosting
Fouillen, Erwan, Boyer, Claire, Sangnier, Maxime
Gradient boosting is a prediction method that iteratively combines weak learners to produce a complex and accurate model. From an optimization point of view, the learning procedure of gradient boosting mimics a gradient descent on a functional variable. This paper proposes to build upon the proximal point algorithm when the empirical risk to minimize is not differentiable. In addition, the novel boosting approach, called accelerated proximal boosting, benefits from Nesterov's acceleration in the same way as gradient boosting [Biau et al., 2018]. Advantages of leveraging proximal methods for boosting are illustrated by numerical experiments on simulated and real-world data. In particular, we exhibit a favorable comparison over gradient boosting regarding convergence rate and prediction accuracy.
Female, minority students took AP computer science in record numbers
Tyson Navarro, 10, of Fremont, Calif., learns to build code using an iPad at a youth workshop at the Apple store in 2013. Code.org said a record number of female and under-represented minority students took AP computer science classes in 2018. SAN FRANCISCO -- Female, black and Latino students took Advanced Placement computer science courses in record numbers, and rural student participation surged this year, as the College Board attracted more students to an introductory course designed to expand who has access to sought-after tech skills. This year, 135,992 students took advanced placement (AP) computer science exams, a 31 percent increase from last year, according to data from the College Board, the organization that administers standardized tests that help determine college entrances as well as AP courses. Females and under-represented minorities were among the fastest growing groups.
Are Teachers About To Be Replaced By Bots?
An attendee looks at a Tifana.com Co. AI service character displayed on a screen at the Artificial Intelligence Exhibition & Conference in Tokyo, Japan, on Wednesday, April 4, 2018. The AI Expo will run through April 6. (Kiyoshi Ota/Bloomberg) It's generally accepted that as technology moves into classrooms, teachers will move, as the saying goes, "from a sage on the stage to a guide on side." That shift has rightly troubled teachers and teaching advocates who fear that educators who instruct, analyze and provide vital context will be diminished or co-opted outright by soulless, algorithm-driven tech. Generally, it's been easy to dismiss those fears in favor of some to-be-determined technology/teacher partnership.
32 Ways AI is Improving Education 7wData
In the last few years, machine learning applications have quietly entered every aspect of life: social media to speech recognition, radiology to retail, warfare to writing articles, coding to customer service, robotics to route optimization. During the 40 year information age, we told computers what to do. With advances in artificial intelligence, particularly machine learning, and faster processing chips we can feed computers giant data sets and they can (in narrow slivers) draw some inferences on their own. As we reported in Ask About AI, the rise of code that learns marks the beginning of a new era of augmented intelligence. It's a great opportunity for us to expand access to a great education and for young people to make a big contribution.
