When associations are based on reference, not values, think arrows, not what value is stored at the location the arrow starts, nor what value is stored at the location of where the arrow ends.

Makes sense to know the sample size, the average, and the average distance each point deviates from the average. Using these numbers, one can calculate the confidence interval When I don't understand,  or just can't process the words, and I end up reading it three times, and the third time I realize what I'm doing, and it makes me so damn heartbroken, my heart gets ripped open, because I am spending a moment on this earth, on my existence, forcing myself to TRY TRY am I going against my own tide. I have such a problem with empty existence. And it is in those moments where I panic at an empty existence. That I could read a sentence three times, like a robot, and not absorb the words. Not only NOT absorb the words, but watch as they send a signal to fill my brain with burning bubbles, like a Willy Wonka chocolate factory suffocation, spinning around and around, brain clenching. Data collection came from two sources (felt heart jump writing this sentence) Periodic popu...

Depending on the initial condition, gradient descent may end up at different local optima. Doubly stochastic normalization STOCHASTIC: Analyzed statistically but not precisely predicted Spectrum analysis of affinity matrix : Pairwise affinity matrix to measure similarity, then NORMALIZE, Logistic regression: Classification into discrete groups.

Gaussian distribution Expectation maximization: Maximum likelihood or "a-posteriori"

Posterior predictive distribution unobserved observations aka PREDICTION CONDITIONAL ON observed data Similar to term "maximum likelihood"

Log Likelihood You have a parameter, you can produce a probability density function given a set of observed values. Log likelihood says take the observed values and find the likelihood of the parameter in the same probability density function kind of way. probability of a DATA VALUE FIXED parameter FIXED data set probability of PARAMETER

So right now, I drag a little droppable item into a select box and some of the code is our and some is from select2 of the internets. Code works when we drop variables in there. Code doesn't work or hasn't actually been written to do things when something is removed minimumInputLength just has to do with each chosen item must be greater than or equal to it's length accept: allows you to add a condition by which the droppable must meet in order for it to be dropped

Gotta go to the developer tools and highlight the element, then click "computed" tab and I saw something called element.style, this could be from style.css, but in my case it was a different possibility, the css can be set in ones javascript file, which was the case for me this time. Say we have a data table with 15 columns, and only 10 columns fit on the screen. Well, a scroller automatically shows up on the data body, and you can easily scroll to see the last 5. The problem is, the titles (data headers) don't move at all, so after scrolling, the user is misinformed as to what the data represents. Header and body will stay together horizontally . I finally found the source for how we implement dataTables taken from https://datatables.net Turns out I just needed to add one extra attribute in the base grid options available in our unique widget implementing dataTables!
