Q

ANNs

FFNNs vs RNNs

A

Artificial Neural Networks

Feed / Fast Forward Neural Network vs. Recurrent Neural Network

Data modeling patterns influenced by Biological systems that are sometimes capable of finding patterns in a “input layer” of features and producing an “output layer” of desired categories.

FFNNs has the “signal” pass from the input layer to the output layer though n number of hidden layers in one direction.

RNNs also have an input layer of features and an output layer of categories, but the signal state is remembered at each hidden layer and may travel in both directions before arriving at the output layer. Most healthcare models are of this type and are also the most expensive to train and deploy.

Q

AI Features vs Predications and Classification

A

AI Features are the input values to a statistical model that are considered to be relevant in calculating the Predictions or Classifications in the output. Classifications refer to assigning a discrete label to the computation of the features.

Q

Deep Learning CNNs

A

Deep Learning Convolutional Neural Networks have many hidden layers and are capable of being better at finding patterns (ie. in X-rays) than clinicians. They are the de facto standard in image processing.

Q

Overfitting

A

A phenomena in ANNs were too many features are used and the model becomes good at predicting in the training set but bad at predicting unseen data from the test set

Q

ANN Regularization

A

Artificial Neural Network Regularization is a set of techniques that help prevent overfitting and improve the models ability to predict generalized data (ie. from the test set).

Q

Ridge regression vs LASSO

A

Ridge regression is a feature optimization technique that does not remove features but decreases some features weight to decrease over-fitting.

LASSO is also a feature optimization technique that may reduce some features weights to zero excluding them from the model.

Q

Which of the following is not a common characteristic of deep learning models?

A.Computationally intensive
B.Use of convolution functions
C.Fewer layers but with more nodes
D.Can identify more obscure patterns in the

A

The answer is C. Fewer layers but with more nodesand here is why. The way deep learning models can capture deeper, morecomplex patterns in the data is by using many layers where each layer can capture some abstract characteristic of the data. Deep learning models commonly use convolutions,and if they do, they are called convolutional neural networks. Because of their complex structure and the use of complex functions such as convolutions, deep learning models are computationally more intensive than traditional models such as general linear models or even basic ANNs

Q

What is one of the advantages of a regularized model over a model that is not regularized?
A.Regularized models are more accurate
B.Regularized models are more generalizable
C.Regularized models use more features
D.Regularized models use advanced computational technology (such as GPUs)

A

The answer is: B. Regularized models are more generalizable, and here is why.When a model is regularized, it will use fewer predictors or assign smaller weights to the predictors and by doing so, it will become less likely

17
Q

Underfitting

A

Underfitting occurs when the model being used is too simple to make predictions. This can occur when there is not enough data in the training set, there are not enough related features, or when the model is too simple like using a linear model with a nonlinear lay distributed data set.

ANNs Predictive vs Prescriptive models

Q

ANNs Feature Selection vs Feature Engineering

A
20
Q

ANN predictor vs feature

A

Artificial Neural Network predictors refer to the entire complete model, then collection of relationships that generates predictions from features as input.

Features are Engineered from a data set to create a predictor model that can be used to generate predictions from new data.
