Do you understand how does logistic regression work? If your answer is yes, I have a challenge for you to solve. Here is an extremely simple logistic problem.

In the Northern Hemisphere, it is the start of the school year, and thousands of eager students are beginning their study of statistics. I know this because this is the time of year when lots of people watch my video, Types of Data. On 23rd August the hits on the video bounced up out of their holiday slumber, just as they do every year. They gradually dwindle away until the end of January when they have a second jump in popularity, I suspect at the start of the second semester.

This tutorial will teach you the main ideas of Unsupervised Feature Learning and Deep Learning. By working through it, you will also get to implement several feature learning/deep learning algorithms, get to see them work for yourself, and learn how to apply/adapt these ideas to new problems. This tutorial assumes a basic knowledge of machine learning (specifically, familiarity with the ideas of supervised learning, logistic regression, gradient descent). If you are not familiar with these ideas, we suggest you go to this Machine Learning course and complete sections II, III, IV (up to Logistic Regression) first.

In the Trust and Safety team at Airbnb, we use the random forest classifier in many of our risk mitigation models. Despite our successes with it, the ensemble of trees along with the random selection of features at each node makes it difficult to succinctly describe how features are being split. In this post, we propose a method to aggregate and summarize those split values by generating weighted threshold distributions.

Causation has long been something of a mystery, bedeviling philosophers and scientists down through the ages. What exactly is it? How can it be measured – that is, can we assess the strength of the relationship between a cause and its effect? What does an observed association between factors – a correlation – tell us about a possible causal relationship? How do multiple factors or causes jointly influence outcomes? And does causation even exist “in the world,” as it were, or is it merely a habit of our minds, a connection we draw between two events we have observed in succession many times, as Hume famously argued? The rich philosophical literature on causation is a testament to the struggle of thinkers throughout history to develop satisfactory answers to these questions. Likewise, scientists have long wrestled with problems of causation in the face of numerous practical and theoretical impediments.

In this notebook, we cover the basics of probability theory, and show how to implement the theory in Python. (You should have a little background in probability and Python.) Then we show how to solve some particularly perplexing paradoxical probability problems.

Natural language generation of coherent long texts like paragraphs or longer documents is a challenging problem for recurrent networks models. In this paper, we explore an important step toward this generation task: training an LSTM (Long-short term memory) auto-encoder to preserve and reconstruct multi-sentence paragraphs.

If you’re following along the SparkR Quick Start, you’ll notice that the instructions are not consistent with a more recent build of Spark. Here are instructions that work for SparkR version 1.4.1 on Linux. YMMV on Spark 1.5.

Missing data can be a not so trivial problem when analysing a dataset and accounting for it is usually not so straightforward either. If the amount of missing data is very small relatively to the size of the dataset, then leaving out the few samples with missing features may be the best strategy in order not to bias the analysis, however leaving out available datapoints deprives the data of some amount of information and depending on the situation you face, you may want to look for other fixes before wiping out potentially useful datapoints from your dataset.
