Anxiety is very interior-focused

 Take a long look in the mirror. Take stock of where you are in life and where you want to be. Can you honestly say your life is working out exactly as you’ve planned? If you see women you’ve hurt in your rearview mirror and a life that’s a bit more empty than you’d like it to be, it might be time to reassess your lifestyle and priorities. And grow the hell up

But for most worriers, Hirsch says that words dominate. Teaching an anxious brain to picture happier scenes or scenarios may help people defang the inner dialogues that fuel their daily anxieties.

Bootstrap sampling is a resampling method that uses random sampling with replacement. It sounds complicated but trust me when I say it’s REALLY simple — read more about it here.

Bagging when you use the aggregate of the bootstrapped datasets to make a decision — I dedicated an article to this topic so feel free to check it out here if this doesn’t make complete sense.

A Support Vector Machine is a supervised classification technique that can actually get pretty complicated but is pretty intuitive at the most fundamental level. For the sake of this article, we’ll keep it pretty high level.

However, if you’re working as part of a team on several related projects (maybe you’re crafting a microservices-based architecture), then workspaces might actually be a very needed feature. Just think about the amount of disk space you’d be saving if you have an architecture of 100 microservices, all of them depending on the same set of modules. That’s where this feature really starts to shine!

“Individuals who often worry or ruminate tend to get stuck in negative, repetitive forms of thought that involve focusing on one’s feelings, problems, and symptoms,” says Jessica Andrews-Hanna, PhD, first author of that study and director of the Neuroscience of Emotion and Thought Lab at the University of Arizona. “Given the repetitive and habitual nature of such thoughts, memories and future thoughts start to lose their detail and become overgeneralized.”

Mehl points out that mindfulness training — which according to research can reduce anxiety, depression, worry, and rumination — shifts a person’s attention toward here-and-now sensory information and away from the self-directed and often verbal forms of inner dialogue.

“Anxiety is very interior-focused, whereas the exterior world is inherently imagery based,” says Matthias Mehl, PhD, a professor of psychology at the University of Arizona. (Some of his work has found that people who talk a lot about themselves — which traditionally has been viewed as a sign of narcissism — is actually an indicator of distress and negative emotions.)

In the study, Andrews-Hanna and her co-author Matthew Grilli divide the imagination and its associated brain networks into two systems, or “styles of thinking.” The first, which she calls “the mind’s eye,” is an image-oriented style that involves “thinking in a detailed and specific way” about a memory or a hypothetical event. The second system, which Andrews-Hanna calls “the mind’s mind,” is a word-oriented system that tends to produce reflective and abstract thoughts and activates parts of the brain that deal with language.

For a forthcoming study in Current Directions in Psychological Science, researchers at the University of Arizona explored the neurological makeup of the human imagination, which includes the mind’s ability to anticipate and fret about future hardships. Like Hirsch’s research, the study finds evidence that worrying may tilt the brain away from vivid mental imagery and toward hazier, language-based patterns of activity.

If the language-oriented parts of the brain become overactive among worriers, image-based therapies might help turn down that overactivity. And Hirsch says she’s now using these insights to inform her clinical work.

Let’s assume that there are two classes of data. A support vector machine will find a hyperplane or a boundary between the two classes of data that maximizes the margin between the two classes (see above). There are many planes that can separate the two classes, but only one plane can maximize the margin or distance between the classes.
