the Autoencoder will have the ability to resist noise.Next, we start introducing PCA-related content.Previously stated Autoencoder can be categorized into Nonliner Autoencoder (because the hidden layer output needs to be tanh, so it is nonlinear).So what if it's linear autoencoder? (The bias unit of the hidden layer is removed here)The last expression of linear autoencoder is: H (x) =WW ' xFrom this, you can write the error functionThis is a 4-order

Date function

DATEADD function
Description: Returns the date when the specified time interval has been added.
Syntax: DateAdd (interval, number, date)
Interval: Must choose. A string expression that represents the time interval to add. For numeric values, see the "Settings" section.
Number: Must be selected. Numeric expression that represents the number of time intervals to add. Numeric expressions can be positive (get future dates) or
Today I built a table with a column of timestamp type, and I meant that when the data was updated, the time of the field was automatically updated. Cruised is not very familiar with the value of this type, resulting in an error. Find that this field is only available when this line of data is set up, and the update is unchanged.
Looking for information, I found that the statement of the table I created a problem:
The following is a code fragment:
