Top 10 Machine Learning Courses for 2020

#artificialintelligence

With solid roots in statistics, Machine Learning is getting one of the most intriguing and quick-paced computer science fields to work in. There's an unending supply of enterprises and applications machine learning can be applied to make them increasingly proficient and wise. Chatbots, spam filtering, ad serving, search engines, and fraud detection, are among only a couple of instances of how machine learning models support regular day to day life. Machine Learning is the thing that lets us discover patterns and make mathematical models for things that would sometimes be unthinkable for people to do. Not at all like data science courses, which contain subjects like exploratory data analysis, statistics, communication, and visualization techniques, machine learning courses concentrate on teaching just the machine learning algorithms, how they work numerically, and how to use them in a programming language.


How to Fix k-Fold Cross-Validation for Imbalanced Classification

#artificialintelligence

Model evaluation involves using the available dataset to fit a model and estimate its performance when making predictions on unseen examples. It is a challenging problem as both the training dataset used to fit the model and the test set used to evaluate it must be sufficiently large and representative of the underlying problem so that the resulting estimate of model performance is not too optimistic or pessimistic. The two most common approaches used for model evaluation are the train/test split and the k-fold cross-validation procedure. Both approaches can be very effective in general, although they can result in misleading results and potentially fail when used on classification problems with a severe class imbalance. In this tutorial, you will discover how to evaluate classifier models on imbalanced datasets.

Data Science Crash Course 3/10: Linear Algebra and Statistics

#artificialintelligence

This is the third instalment of Data Science Crash Course and today we're going to review mathematics needed for Data Science. Linear algebra is all about manipulations with vectors and matrices. It's both notation and useful way of manipulating object. You can perform operations on vectors like adding by adding each respective term -- they need to have the same length. You can multiply a vector by a scalar, that is a real number, by multiplying each of the entries by this real number.


Free Online Course: Fundamentals of Machine Learning from Complexity Explorer Class Central

#artificialintelligence

Machine Learning is a fast growing, rapidly advancing field that touches nearly everyone's lives. There has recently been an explosion of successful machine learning applications - in everything from voice recognition to text analysis to deeper insights for researchers. While common and frequently talked about, most people have only a vague concept of how machine learning actually works. In this tutorial, Dr. Artemy Kolchinsky and Dr. Brendan Tracey outline exactly what it is that makes machine learning so special in an accessible way. The principles of training and generalization in machine learning are explained with ample metaphors and visual intuitions, an extended analysis of machine learning in games provides a thorough example, and a closer look at the deep neural nets that are the core of successful machine learning.

Finland is challenging the entire world to understand AI by offering a completely free online course - initiative got 1 % of the Finnish population to study the basics University of Helsinki

#artificialintelligence

Finnish technology firm Reaktor and the University of Helsinki joined forces to educate people on AI for free. The institutions combined to develop an online course to teach the basics of AI to anyone interested in the technology. Reaktor and the University also challenged organizations to train their staff in AI, so far over 200 organisations have pledged to do so – including banks, telecoms, and healthcare organizations. Almost 90 000 students have signed up for the course since it began in May. While popular with Finns, the course is already seeing strong demand globally, attracting students from over 80 different countries.
