You’ve just finished training an ensemble tree method for spam classification, and it is getting abnormally bad performance on y

our validation set, but good performance on your training set. Your implementation has no bugs. Define various reasons that could be causing the problem?

Answer:

The various reasons that could be a major problem for the implementation are it involves a large number of parameters also, having a noisy data

Explanation:

Solution

The various reasons that could be causing the problem is given as follows :

1. A wide number of parameters :

  • In the ensemble tree method, the number of parameters which are needed to be trained is very large in numbers.
  • When the training is performed in this tree, then the model files the data too well.
  • When the model has tested against the new data point form the validation set, then this causes a large error because the model is trained completely according to the training data.

2. Noisy Data:

  • The data used to train the model is taken from the real world . The real world's data set is often noisy i.e. contains the missing filed or the wrong values.
  • When the tree is trained on this noisy data, then it sets its parameters according to the training data.
  • As regards to testing the model by applying the validate set, the model gives a large error of high in accuracy y.

yaroslaw [1]

Answer:

<em>The program doesn't use comments; See explanation section for detailed line by line explanation</em>

<em>Program starts here</em>

def lettergrade(subject,score):

     print(subject+": "+str(score))

     if score >= 90 and score <= 100:

           print("Letter Grade: A")

     elif score >= 80 and score <= 89:

           print("Letter Grade: B")

     elif score >= 70 and score <= 79:

           print("Letter Grade: C")

     elif score >= 60 and score <= 69:

           print("Letter Grade: D")

     elif score >= 0 and score <= 59:

           print("Letter Grade: F")

     else:

           print("Invalid Score")

maths = int(input("Maths Score: "))

english = int(input("English Score: "))

pe = int(input("PE Score: "))

science = int(input("Science Score: "))

arts = int(input("Arts Score: "))

lettergrade("Maths Class: ",maths)

lettergrade("English Class: ",english)

lettergrade("PE Class: ",pe)

lettergrade("Science Class: ",science)

lettergrade("Arts Class: ",arts)

Explanation:

The program makes the following assumptions:

Scores between 90–100 has letter grade A

Scores between 80–89 has letter grade B

Scores between 70–79 has letter grade C

Scores between 60–69 has letter grade D

Scores between 0–69 has letter grade E

<em>Line by Line explanation</em>

This line defines the lettergrade functions; with two parameters (One for subject or class and the other for the score)

def lettergrade(subject,score):

This line prints the the score obtained by the student in a class (e.g. Maths Class)

     print(subject+": "+str(score))

The italicized determines the letter grade using if conditional statement

<em>This checks if score is between 90 and 100 (inclusive); if yes, letter grade A is printed</em>

<em>      if score >= 90 and score <= 100:</em>

<em>            print("Letter Grade: A")</em>

<em />

<em>This checks if score is between 80 and 89 (inclusive); if yes, letter grade B is printed</em>

<em>      elif score >= 80 and score <= 89:</em>

<em>            print("Letter Grade: B")</em>

<em />

<em>This checks if score is between 70 and 79 (inclusive); if yes, letter grade C is printed</em>

<em>      elif score >= 70 and score <= 79:</em>

<em>            print("Letter Grade: C")</em>

<em />

<em>This checks if score is between 60 and 69 (inclusive); if yes, letter grade D is printed</em>

<em>      elif score >= 60 and score <= 69:</em>

<em>            print("Letter Grade: D")</em>

<em />

<em>This checks if score is between 0 and 59 (inclusive); if yes, letter grade F is printed</em>

<em>      elif score >= 0 and score <= 59:</em>

<em>            print("Letter Grade: F")</em>

<em />

<em>If input score is less than 0 or greater than 100, "Invalid Score" is printed</em>

<em>      else:</em>

<em>            print("Invalid Score")</em>

This line prompts the user for score in Maths class

maths = int(input("Maths Score: "))

This line prompts the user for score in English class

english = int(input("English Score: "))

This line prompts the user for score in PE class

pe = int(input("PE Score: "))

This line prompts the user for score in Science class

science = int(input("Science Score: "))

This line prompts the user for score in Arts class

arts = int(input("Arts Score: "))

The next five statements is used to call the letter grade function for each class

lettergrade("Maths Class: ",maths)

lettergrade("English Class: ",english)

lettergrade("PE Class: ",pe)

lettergrade("Science Class: ",science)

lettergrade("Arts Class: ",arts)

Select the correct answer.
andriy [413]

Answer:

C. Rulers indicate the margins, tabs, and indents in a presentation slide.

Explanation:

The status bar appears at the bottom of the page, and it never displays options the options to style the slides. And the toolbar never displays the thumbnails of the slides, as well as the document area never provides a list of the commands for creating, formatting or editing the presentations. However, the rules do indicates the margins, tabs, and indents in a presentation slide. Hence C. is the right option.

How will you apply the different wiring devices according to its main purposes and functions?
Gekata [30.6K]

Answer:Wiring devices are current-carrying electrical or electronic products that serve primarily as a connection or control point for electrical circuits within a range of 0–400 amperes, 0–600 volts (AC and DC), and AC/DC (660 watts, 1,000 volts AC fluorescent) as well as certain non-current-carrying wiring devices and supplies.

Wiring devices include:

Convenience plugs and power outlets (plugs and receptacles)

Connector bodies and flanged outlets

Cover plates

General-use switches and dimmers

Lampholders (incandescent, fluorescent, cold cathode, neon, quartz lamps, and others)

Lighting control devices

Motion sensing and timer switches

Receptacles

Switch, outlet, FM/TV, blank, and telephone plates

Undercarpet premise wiring systems

Products include receptacle-type arc-fault circuit interrupters (AFCIs), protection devices that can detect an unintended electrical arc and disconnect the power before the arc starts a fire. AFCI technology in residential and commercial buildings is an important electrical safety device.
