Udemy Coupon [2020] 12 Real World CaseStudies for Machine Learning

#artificialintelligence

You might know the theory of Machine Learning and know how to create algorithms. But as you know you must get your hands Dirty on Real-World Case Studies. There are so many courses which teaches the basic of Machine Learning But do not cover the Applications. This course will help you bridge the gap between a person who knows machine learning and a person who actually know how to apply Machine Learning in real world. Knowing Machine learning and Applying it in the real world is totally different.


Rethink upskilling

#artificialintelligence

Upskilling is the new corporate mantra, and unless you're running an AI-only startup (and maybe even then), your workforce needs it. But the old kind of upskilling -- offering learning opportunities focused on a siloed technology -- is not enough to get your employees or your company ready for AI at scale. True upskilling requires more than offering training courses. As executives in our survey recognized (50%), you also need to give immediate opportunities and incentives for people to apply what they've learned, so that knowledge turns into real-world skills that improve performance. Such a citizen-led approach is not only the most effective way to teach tech chops like creating data sets, building a machine learning model, or using Python or R notebooks.


FUTURE SHOCK: 25 Education trends post COVID-19 - ET BrandEquity

#artificialintelligence

Future Shock: 25 trends in education post COVID-19.By Sandeep Goyal This Future Shock series is inspired by the Alvin Toffler book with the same name, first published in the 1970s. The book future gazed a rapidly changing world, propelled into newer and newer orbits by not just science and technology, but by newer political realities, sociological change and the emergence of newer opportunities, newer aspirations and newer lifestyles. But even Toffler had not visualized a world faced with cataclysmic change because of a pandemic, a metamorphosis triggered by a virus. Most governments around the world have temporarily closed educational institutions in an attempt to contain the spread of the COVID-19 pandemic. Some 1.3-1.5 billion students and youth across the planet are affected by school and university closures. These nationwide closures are impacting over 72% of the world's student population. Several other countries have implemented localized closures impacting millions of additional learners. Governments around the world are making efforts to mitigate the immediate impact of school closures, particularly for more vulnerable and disadvantaged communities, and to facilitate the continuity of education for all through remote learning. School closures carry high social and economic costs for people across communities. Their impact however is particularly severe for the most vulnerable and marginalized boys and girls, and their families.


Language schools struggling to survive as virus keeps students out of Japan

The Japan Times

With the coronavirus pandemic choking social interaction and global travel, many of the nation's approximately 800 Japanese-language schools are struggling because new students have not been able to enter Japan. Since private schools basically rely on tuition fees, they are facing an existential crisis, people familiar with the matter say. Enrollment at Japanese-language schools halved to around 50,000 from about 100,000 in March due to graduation and other reasons, including coronavirus restrictions, they said. Japan has banned the entry of people from 100 countries and regions as part of efforts to curb the pandemic. According to the Justice Ministry, students can enroll in a Japanese school for up to two years.

Grading on a curve? Why AI systems test brilliantly but stumble in real life - ScienceBlog.com

#artificialintelligence

The headline in early 2018 was a shocker: "Robots are better at reading than humans." Two artificial intelligence systems, one from Microsoft and the other from Alibaba, had scored slightly higher than humans on Stanford's widely used test of reading comprehension. The test scores were real, but the conclusion was wrong. As Robin Jia and Percy Liang of Stanford showed a few months later, the "robots" were only better than humans at taking that specific test. Because they had trained themselves on readings that were similar to those on the test.


Generalized Bayesian Posterior Expectation Distillation for Deep Neural Networks

arXiv.org Machine Learning

Monte Carlo methods provide one solution to represent neural network parameter posteriors as ensembles of networks, but this requires In this paper, we present a general framework large amounts of both storage and compute time (Neal, for distilling expectations with respect to the 1996; Welling and Teh, 2011). Bayesian posterior distribution of a deep neural network classifier, extending prior work on To help overcome these problems, Balan et al. (2015) introduced the Bayesian Dark Knowledge framework. The a model training method referred to as Bayesian proposed framework takes as input "teacher" Dark Knowledge (BDK). BDK attempts to compress (or and student model architectures and a general distill) the Bayesian posterior predictive distribution induced posterior expectation of interest. The distillation by the full parameter posterior of a "teacher" network method performs an online compression (represented via a set of Mote Carlo samples) into a of the selected posterior expectation using iteratively significantly more compact "student" network. The major generated Monte Carlo samples. We advantage of BDK is that the computational complexity focus on the posterior predictive distribution of prediction at test time is drastically reduced compared and expected entropy as distillation targets. We to directly computing predictions via Monte Carlo averages investigate several aspects of this framework over the set of teacher network samples (the teacher including the impact of uncertainty and the ensemble).


Achieving Online Regression Performance of LSTMs with Simple RNNs

arXiv.org Machine Learning

Recurrent Neural Networks (RNNs) are widely used for online regression due to their ability to generalize nonlinear temporal dependencies. As an RNN model, Long-Short-Term-Memory Networks (LSTMs) are commonly preferred in practice, as these networks are capable of learning long-term dependencies while avoiding the vanishing gradient problem. However, due to their large number of parameters, training LSTMs requires considerably longer training time compared to simple RNNs (SRNNs). In this paper, we achieve the online regression performance of LSTMs with SRNNs efficiently. To this end, we introduce a first-order training algorithm with a linear time complexity in the number of parameters. We show that when SRNNs are trained with our algorithm, they provide very similar regression performance with the LSTMs in two to three times shorter training time. We provide strong theoretical analysis to support our experimental results by providing regret bounds on the converge rate of our algorithm. Through an extensive set of experiments, we verify our theoretical work and demonstrate significant performance improvements of our algorithm with respect to LSTMs and the state-of-the-art training methods.


Predicting into unknown space? Estimating the area of applicability of spatial prediction models

arXiv.org Machine Learning

Predictive modelling using machine learning has become very popular for spatial mapping of the environment. Models are often applied to make predictions far beyond sampling locations where new geographic locations might considerably differ from the training data in their environmental properties. However, areas in the predictor space without support of training data are problematic. Since the model has no knowledge about these environments, predictions have to be considered uncertain. Estimating the area to which a prediction model can be reliably applied is required. Here, we suggest a methodology that delineates the "area of applicability" (AOA) that we define as the area, for which the cross-validation error of the model applies. We first propose a "dissimilarity index" (DI) that is based on the minimum distance to the training data in the predictor space, with predictors being weighted by their respective importance in the model. The AOA is then derived by applying a threshold based on the DI of the training data where the DI is calculated with respect to the cross-validation strategy used for model training. We test for the ideal threshold by using simulated data and compare the prediction error within the AOA with the cross-validation error of the model. We illustrate the approach using a simulated case study. Our simulation study suggests a threshold on DI to define the AOA at the .95 quantile of the DI in the training data. Using this threshold, the prediction error within the AOA is comparable to the cross-validation RMSE of the model, while the cross-validation error does not apply outside the AOA. This applies to models being trained with randomly distributed training data, as well as when training data are clustered in space and where spatial cross-validation is applied. We suggest to report the AOA alongside predictions, complementary to validation measures.
