Answer:

Explanation:

A digital camera refers to a camera whereby the photographs are being captured in digital memory. An analogue camera refers to the traditional camera that typically sends video over cable.

The advantages of digital cameras over analogue cameras include:

1. Massive Storage Space:

There is a large storage space for photos and thus helps to prevent limitations to film. There are memory cards that can store several images.

2. Multiple functions:

The digital camera performs several functions like face detection, night and motion detection This makes capturing of images more fun and brings about better images.

3. Video Camera:

Digital cameras can also capture moving pictures while analog camera typically captures images that are still. Digital camera is vital as it can be used for live streaming.

4. Smaller and Lighter:

Digital cameras are usually smaller and lighter which makes them more portable and easy to carry about.

Answer:

Cloud computing

Explanation:

Cloud computing is simply defined as the usage of computer resources or networks to communicate with a person or persons over the internet.

This has to do with the exchange of ideas or information between two or more parties over the internet and this can be achieved by using a service such as an email to collaborate, meet or discuss with a person or group online.

The processing that’s done by the DBMS is typically referred to as:______.

Vilka [71]

Answer:

Option b is the correct answer for the above question.

Explanation:

The DBMS is used to manage the information or data which is stored to use in the future. Any project has two sides one is the front end and the other is back-end. The front-end refers to the graphics which are visible to the user of the project but the data is not stored on the side of the project it is stored on any database software which can be called for the request of any event of the project. The database is stored on the backed of the project so to bring the data from the database, the process is known as back-end processing.

The above question wants to ask about the process of DBMS which is said to the back-end process because the DBMS process the data and to process the data is known as the back-end process. So Option b is the correct while the other is not because--

Option 'a' states about front-end-processing which processes the design of the websites.
Option c states about the file server which is said to the DBMS.
Option d states about the management system which is not in the project.

Lasso: R example

To run Lasso Regression you can re-use the glmnet() function, but with the alpha parameter set to 1.

# Perform 10-fold cross-validation to select lambda --------------------------- lambdas_to_try <- 10^seq(-3, 5, length.out = 100) # Setting alpha = 1 implements lasso regression lasso_cv <- cv.glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = TRUE, nfolds = 10) # Plot cross-validation results plot(lasso_cv)

Best cross-validated lambda lambda_cv <- lasso_cv$lambda.min # Fit final model, get its sum of squared residuals and multiple R-squared model_cv <- glmnet(X, y, alpha = 1, lambda = lambda_cv, standardize = TRUE) y_hat_cv <- predict(model_cv, X) ssr_cv <- t(y - y_hat_cv) %*% (y - y_hat_cv) rsq_lasso_cv <- cor(y, y_hat_cv)^2 # See how increasing lambda shrinks the coefficients -------------------------- # Each line shows coefficients for one variables, for different lambdas. # The higher the lambda, the more the coefficients are shrinked towards zero. res <- glmnet(X, y, alpha = 1, lambda = lambdas_to_try, standardize = FALSE) plot(res, xvar = "lambda") legend("bottomright", lwd = 1, col = 1:6, legend = colnames(X), cex = .7)
