5 Famous Deep Learning Courses/Schools of 2019 - KDnuggets
Deep Learning is/has become the hottest skill in Data Science at the moment. There is a plethora of articles, courses, technologies, influencers and resources that we can leverage to gain the Deep Learning skills. Deep Learning is not just one thing though! There are so many applications that one cannot simply learn all in a short span of time (maybe some can but having learnt it is not the same as being skilled in it). This list will comprise of resources / courses that are the most famous right now.
10 Great Python Resources for Aspiring Data Scientists - Predictive Analytics Times - machine learning & data science news
Python is one of the most widely used languages in data science, and an incredibly popular general programming language on its own. Many prospective data scientists are first faced with the issue of which programming language might be their choice when diving into data science. This is further complicated if you don't already bring a set of existing programming skills on which to rely. Even better would be a thorough understanding of Python as you shift to data science (substitute another language if it is to be your preferred data science programming tool), but many newcomers to the field find themselves either starting from relative scratch when it comes to either programming in general, or Python more specifically. This is a collection of 10 interesting resources in the form of articles and tutorials for the aspiring data scientist new to Python, meant to provide both insight and practical instruction when starting on your journey.
Is Rectified Adam actually *better* than Adam? - PyImageSearch
Is the Rectified Adam (RAdam) optimizer actually better than the standard Adam optimizer? According to my 24 experiments, the answer is no, typically not (but there are cases where you do want to use it instead of Adam). In Liu et al.'s 2018 paper, On the Variance of the Adaptive Learning Rate and Beyond, the authors claim that Rectified Adam can obtain: The authors tested their hypothesis on three different datasets, including one NLP dataset and two computer vision datasets (ImageNet and CIFAR-10). In each case Rectified Adam outperformed standard Adam…but failed to outperform standard Stochastic Gradient Descent (SGD)! The Rectified Adam optimizer has some strong theoretical justifications -- but as a deep learning practitioner, you need more than just theory -- you need to see empirical results applied to a variety of datasets. And perhaps more importantly, you need to obtain a mastery level experience operating/driving the optimizer (or a small subset of optimizers) as well. If you haven't yet, go ahead and read part one to ensure you have a good understanding of how the Rectified Adam optimizer works. From there, read today's post to help you understand how to design, code, and run experiments used to compare deep learning optimizers. To learn how to compare Rectified Adam to standard Adam, just keep reading! In the first part of this tutorial, we'll briefly discuss the Rectified Adam optimizer, including how it works and why it's interesting to us as deep learning practitioners.
Our digital future 11: AI enhanced course design

We have traversed several emerging ideas, including the use of virtual teaching assistants (chatbots), ultra-personalised learning and machine intelligence, but the most important component in education is still the human element. Other jobs in society may already have been supplanted by robotics and artificial intelligence. Mostly, they are repetitive, low level or dangerous jobs, but replacing teachers with computers is neither desirable nor expedient. However, replacing some aspects of what teachers do is both effective and inevitable.

How to Develop a Naive Bayes Classifier from Scratch in Python
Classification is a predictive modeling problem that involves assigning a label to a given input data sample. The problem of classification predictive modeling can be framed as calculating the conditional probability of a class label given a data sample. Bayes Theorem provides a principled way for calculating this conditional probability, although in practice requires an enormous number of samples (very large-sized dataset) and is computationally expensive. Instead, the calculation of Bayes Theorem can be simplified by making some assumptions, such as each input variable is independent of all other input variables. Although a dramatic and unrealistic assumption, this has the effect of making the calculations of the conditional probability tractable and results in an effective classification model referred to as Naive Bayes.
