Descriptive Analytics What happened Predictive Analytics What will happen Prescriptive Analytics What action(s) would be best algorithm Step-by-step procedure designed to carry out a task. change detection Identifying when a significant change has taken place in a process. classification The separation of data into two or more categories, or (a point's classification) the category a data point is put into. classifier A boundary that separates the...

What does SVM stand for? Support Vector Machine Is written text structured or unstructured? Unstructured When we increase the sum of the square of the coefficients we... Decrease the distance between the lines In SVM soft classifier we tradeoff between maximizing ___ and minimizing ___ margin and errors If lambda gets small what gets emphasized, large margin or minimizing training error?, Minimizing errors. What is a support vector? A point that holds up ...

Descriptive Question Questions that ask for explanations of what happened Predictive Questions Questions that ask what's going to happen in the future Prescriptive Questions Questions that ask what action or actions would be best General Questions Generic questions on data analytics Modeling A mathematical expression of a real-life situation Classification Putting things into categories Classifiers Separators Data Point A single observati...

The concept of health and healing has evolved in recent years. Which is the best description of health? a. Health is the absence of disease. b. Health is a dynamic process toward optimal functioning. c. Health depends on an interaction of mind, body, and spirit within the environment. d. Health is the prevention of disease. c. Health depends on an interaction of mind, body, and spirit within the environment. Which would be included in the database for a new patient admission to a s...

The nurse needs to pull the portion of the ear that consists of movable cartilage and skin down and back when administering eardrops. This portion of the ear is called the: a. Auricle. b. Concha. c. Outer meatus. d. Mastoid process. A. auricle The external ear is called the auricle or pinna and consists of movable cartilage and skin. The nurse is examining a patient's ears and notices cerumen in the external canal. Which of these statements about cerumen is correct? a....

Evidence based practice a systematic approach emphasizing the best research evidence, the clinicians experience, patient preferences and values, physical examination, and assessment. Subjective Data SYMPTOMS: What the person says about him or herself during history taking. Objective Data SIGNS: What the health professional observes by inspecting, palpating, percussing and osculating during the physical examination. Diagnostic Reasoning the process of taking the informati...

What is modeling? Describing a real life situation mathematically Model Mathematical approaches to solving analytics problems 1. Regression for ex. can be called the model of choice. 2. If more detail (descriptive and numerical), the use of, for ex. Regression, can be called the model. 3. The actual values and output along with 1 and 2 can be referred to as the model. Cross Cutting Concepts Preparing data, measuring the quality of a model's output, missing data, etc.. ...

1-norm Similar to rectilinear distance; measures the straight-line length of a vector from the origin. If z=(z1,z2,...,zm) is a vector in an m-dimensional space, then it's 1-norm is square root(|

greedy algorithm at each step, the algorithm does the thing that looks best without taking future options into consideration; more classical variable selection methods stepwise - (forward, backward, combination) lasso elastic net available metrics for variable selection criteria p-value r2 AIC / BIC lasso Giving regression a budget to use on coefficients which it uses on most important coefficients Have to scale first elastic net constrain combination of abs...

Rows Data points are values in data tables Columns The 'answer' for each data point (response/outcome) Structured Data Quantitative, Categorical, Binary, Unrelated, Time Series Unstructured Data Text Support Vector Model Supervised machine learning algorithm used for both classification and regression challenges. Mostly used in classification problems by plotting each data item as a point in n-dimensional space (n is the number of features you have) with the v...
