### Statistics For Dummies: Indexing And Subsetting In R [Part 2 of 2] : Lists And Data Frames

Last time, we discussed how to index or subset vectors and matrices in R. Now, we will deal with indexing the other commonly used R objects: lists and data frames. Typically, we will not be dealing with data with the level of simplicity of vectors and matrices. Most of the time, more structure with the …

### Statistics For Dummies: Indexing and Subsetting In R [Part 1 of 2] : Vectors And Matrices

Previously, we talked about the objects in R and how they are created. Now, we will discuss how information can be extracted from these objects. This process is also known as indexing or subsetting. The ability to access information is important since there are times that we only need a specific data point or subset …

### Statistics For Dummies: Introduction To R Objects

R is a programming language and software environment designed with statistical computing in graphics in mind. In R, information is stored in entities called objects. It’s through these objects that you can perform data manipulations, operations, and analysis in R. Here, we will introduce the main types of R objects and how you can create …

### Here Are 3 Ways Artificial Intelligence Will Change Healthcare By 2030

### What Is It To Be Bayesian? The (Pretty Simple) Math Modelling Behind A Big Data Buzzword

If you’ve ever tripped up over the term ‘Bayesian’ while reading up on data or tech, fear not. Strip away the jargon and notation, and even the mathematics-averse can make sense of the simple yet revolutionary concept at the core of both machine learning and behavioural economics. As this video from the YouTube channel 3Blue1Brown …

### The Autonomous Killing Systems Of The Future Are Already Here, They’re Just Not Necessarily Weapons – Yet

When the discussion of “autonomous weapons systems” inevitably prompts comparisons to Terminator-esque killer robots it’s perhaps little surprise that a number of significant academics, technologists, and entrepreneurs including Stephen Hawking, Noam Chomsky, Elon Musk, Demis Hassabis of Google and Apple founder Steve Wozniak signed a letter calling for a ban on such systems. The signatories …

### Abstract Thinking Makes Robots Better Planners

Researchers have developed a method for helping robots plan for multi-step tasks by constructing abstract representations of the world around them. Their study is a step toward building robots that can think and act more like people. Planning is a monumentally difficult thing for robots, largely because of how they perceive and interact with the …
