Digest #2020.01.27 – Which Algorithm Should I Use?

Using AI to Enrich Digital Maps – Your commute may now be saved from the road closures, private routes and diversions! Researchers at MIT and Qatar Computing Research Institute (QCRI) have invented a model that could improve GPS navigation on digital maps.An interesting read about the research combining convolutional neural network (CNN) and graph neural network (GNN) to tag road features and predict the types of roads, lanes and obstruction along the route.

Solving Problems with TensorFlow – A good article on solving practical problems with TensorFlow. The article walks through solving an optimization problem, solving a linear regression problem, and a “Hello World” of Deep Learning classification projects with the MNIST Dataset. Check out for an interesting “getting started with tensorFlow” and train a neural network with visual representations and some fun.

Which Machine Learning Algorithm Should I Use? – One of the most common questions in the machine learning space; people are often confused about their ML needs and do not know the right qualifying questions to ask. The Microsoft team provides a walkthrough on how to decide the answer to which machine algorithm to use. It usually comes down to what are the requirements for your scenario? And, what do you want to do with your data?  There are some neat cheat sheets for reference.

Data Sampling Methods for Imbalanced Classification – At some point we’ve all probably been thrown off by over-optimistic performance of machine learning solutions. The author walks through the challenges of machine learning with imbalanced classifications, a tutorial on sampling techniques to handle skewed class distributions, and explanations of undersampling, oversampling and a hybrid of both. A well-put tutorial for learning!
