Training neural networks requires two steps. In the forward pass we compute the output of the network and the loss given the input, and in the backward pass we compute the derivatives for all the parameters given the loss, and the values computed in the forward pass. Take the regression network of slide 10 of lecture 6 ("Beyond linear models") and assume you have some instance, some target value and, and that you are using squared error loss. Write pseudocode for the forward and backward pass. You may use a separate variable for each node in the network, or store all the values of one layer in a list or similar datastructure. You can use whatever form of pseudocode seems most appropriate, but the more detailed it is, the better. When in doubt, we suggest making it as close to runnable python code as you can.
Training a regression network with squared error loss requires two steps: the forward pass and the backward pass.
Forward Pass:
Let x be the input to the neural network, y be the target value, w be the weights of the neural network, and h be the output of the neural network.Initialize an empty array l to store the output of each layer.Compute the output of the first layer l[0] with the weights w[0] and the input x, and store it in l[0].Compute the output of the second layer l[1] with the weights w[1] and the input l[0], and store it in l[1].Compute the output of the third layer h with the weights w[2] and the input l[1], and store it in h.Compute the loss between y and h, using the squared error loss function.Backward Pass:
Let delta be the derivative of the loss with respect to h.Compute the derivative of the loss with respect to l[2] with delta and the weights w[2].Compute the derivative of the loss with respect to l[1] with the derivative of the loss with respect to l[2] and the weights w[1].Compute the derivative of the loss with respect to l[0] with the derivative of the loss with respect to l[1] and the weights w[0].Compute the derivative of the loss with respect to w[2] with delta and the input l[1].Compute the derivative of the loss with respect to w[1] with the derivative of the loss with respect to l[2] and the input l[0].Compute the derivative of the loss with respect to w[0] with the derivative of the loss with respect to l[1] and the input x.Learn more about derivative

What is the percentage?
A number or ratio that can be expressed as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100. The percentage, therefore, refers to a part per hundred. Per 100 is what the word percent means. The letter "%" stands for it.
The sample number is 150.
Given that 3% of the chimpanzees are hairless, another sample indicates that 5% are hairless, and a third sample indicates that 4% are hairless.
The average percentage of chimpanzees of hairless is

The table lists the ring size S for a finger with circumference x in centimeters. x (cm) 4.87 5.66 5.92 6.71 S (size) 4 7 8 11 a. Find a linear function S that models the data. b. Find the circumference of a finger with a ring size of 6.
The linear function that models the data is S = 3.8x - 14.506 and the circumference of a finger with a ring size of 6 is 5.4 cm.
a. To find a linear function S that models the data, we need to find the slope and y-intercept of the line that best fits the data. The slope can be found by using the formula:
m = (y2 - y1) / (x2 - x1)
Using the first two data points, we can find the slope:
m = (7 - 4) / (5.66 - 4.87)
m = 3 / 0.79
m = 3.8
To find the y-intercept, we can use the formula:
y = mx + b
Substituting one of the data points and the slope into the formula and solving for b:
4 = (3.8)(4.87) + b
b = 4 - (3.8)(4.87)
b = -14.506
So the linear function that models the data is:
S = 3.8x - 14.506
b. To find the circumference of a finger with a ring size of 6, we can substitute S = 6 into the linear function and solve for x:
6 = 3.8x - 14.506
3.8x = 20.506
x = 5.4 cm
So the circumference of a finger with a ring size of 6 is 5.4 cm.

How do u change this from vertex form y=2(x-2)^2+5 to standard form?
The standard form for the quadratic equation written in vertex form y = 2(x - 2)² + 5 is y = 2x² - 8x + 13.
What is a quadratic function?
A polynomial function with one or more variables, where the largest exponent of the variable is two, is referred to as a quadratic function. It is also known as the polynomial of degree 2 since the greatest degree term in a quadratic function is of second degree.
To change the equation y = 2(x - 2)² + 5 from vertex form to standard form, we need to expand the squared term and simplify the expression.
Here are the steps -
Start with the vertex form: y = 2(x - 2)² + 5.
Expand the squared term using the formula (a - b)² = a² - 2ab + b².
In this case, a = x and b = 2, so we have -
y = 2(x - 2)(x - 2) + 5
y = 2(x² - 4x + 4) + 5
Multiply the coefficient 2 by each term inside the parentheses -
y = 2x² - 8x + 8 + 5
Combine the constant terms -
y = 2x² - 8x + 13
This is the standard form of the quadratic equation.
In standard form, the quadratic equation is written as y = ax² + bx + c, where a, b, and c are constants.
In this case, a = 2, b = -8, and c = 13.
Therefore, the standard form is y = 2x² - 8x + 13.

The model for the BMI of a person is:
BMI = (152100/weight in pounds)/(height in inches)^2
The Body Mass Index (BMI) of a person can be calculated using the formula:
BMI = (weight in pounds)/(height in inches)^2
In this case, the BMI varies directly as a person's weight in pounds and inversely as the square of the person's height in inches. This means that as the weight increases, the BMI increases and as the height increases, the BMI decreases.
To find a model for the BMI of a person, we can use the formula:
BMI = k(weight in pounds)/(height in inches)^2
Where k is a constant of proportionality. To find the value of k, we can use the given information that a 6ft 6in tall person has a BMI of 25.
First, we need to convert the height from feet and inches to inches. 6ft 6in is equivalent to 78 inches. Then, we can plug in the values into the formula and solve for k:
25 = k(weight in pounds)/(78 inches)^2
25(78 inches)^2 = k(weight in pounds)
152100 = k(weight in pounds)
Therefore, the model for the BMI of a person is:
BMI = (152100/weight in pounds)/(height in inches)^2
This model can be used to calculate the BMI of a person given their weight in pounds and height in inches.

The current temperature is 48\deg F. It is expected to drop 1.5\deg F each hour. Which equation can be used to find in how many hours, h, the temperature will be 36\deg F?
Answer:
Let's start by defining some variables to represent the given information:
T0 = 48°F (the current temperature)
deltaT = -1.5°F/hour (the rate of change in temperature)
T = 36°F (the target temperature)
We want to find how many hours it will take for the temperature to drop from 48°F to 36°F, so let's call that time h. We can use the formula for the linear relationship between temperature and time:
T = T0 + deltaT * h
We want to solve for h when T = 36°F, so we can substitute the given values and solve for h:
36 = 48 + (-1.5) * h
-12 = -1.5h
h = 8
Therefore, it will take 8 hours for the temperature to drop from 48°F to 36°F, assuming the temperature continues to decrease at a rate of 1.5°F per hour.
Qe. For the following arithmetic serles, find: a_(1),d,a_(n),n 1a.27,31,35,dots, 783,a_(1)= d= a_(n)= n^(2)
For the given arithmetic series, a_(1) = 27, d = 4, a_(n) = 783, n = 190, and n^(2) = 36100.
The given arithmetic series is 27, 31, 35,..., 783.
To find the first term, a_(1), we can simply look at the first term in the series. Therefore, a_(1) = 27.
To find the common difference, d, we can subtract the first term from the second term, or the second term from the third term. Therefore, d = 31 - 27 = 4.
To find the nth term, a_(n), we can use the formula a_(n) = a_(1) + (n - 1)d. We know that a_(1) = 27, d = 4, and a_(n) = 783, so we can plug these values into the formula and solve for n:
783 = 27 + (n - 1)(4)
756 = (n - 1)(4)
189 = n - 1
n = 190
Therefore, the nth term is 190.
To find the value of n^(2), we can simply square the value of n:
n^(2) = 190^(2) = 36100
Therefore, the value of n^(2) is 36100.

What is coordinates ?A coordinate system is a method that employs one or more values or coordinates to accurately locate points or even other mathematical objects on a space, such as Euclidean space. Coordinates, that are pairs of numbers, are used to locate a point or object on a double plane. The y and x vectors are two integers that specify where a point is situated on a two - dimensional plane. a group of numerals designating particular places. Usually, the number has two numbers.
Here,
By adding 1 to the x-coordinate and 3 to the y-coordinate, we can determine that position A is translated to point A'. As a result, we can determine the values of B' and C' using the same translation vector.

3/3 * (x/x) - x/x * (4/3) = (3x - 4x)/3x = (-x)/3x. Now, we can simplify the expression by canceling out the common factor of x in the numerator and denominator. (-x)/3x = -1/3
The simplified expression is -1/3.

How many numbers cansisting of 3 digits can be made from 1,2,3,4,5, and 6 if letter A repitition is allowed, letfer B repitition is not allowed.
Answer:
If repetition of letter A is allowed and letter B cannot be repeated, then there are two cases to consider when constructing a 3-digit number:
Case 1: The first digit is letter A. In this case, there are 6 options for the first digit (since any of the 6 digits can be used), and there are 5 options for each of the remaining digits (since letter B cannot be repeated). Therefore, the total number of 3-digit numbers that can be formed in this case is:
6 x 5 x 5 = 150
Case 2: The first digit is not letter A. In this case, there are 5 options for the first digit (since letter A cannot be repeated), and there are 5 options for each of the remaining digits (since letter B cannot be repeated). Therefore, the total number of 3-digit numbers that can be formed in this case is:
5 x 5 x 4 = 100
To get the total number of 3-digit numbers that can be made from 1, 2, 3, 4, 5, and 6 with letter A repetition allowed and letter B repetition not allowed, we add the number of possibilities from Case 1 and Case 2:
Total = 150 + 100 = 250
Therefore, there are 250 different 3-digit numbers that can be made from 1, 2, 3, 4, 5, and 6 with letter A repetition allowed and letter B repetition not allowed.
There are 720 numbers consisting of 3 digits that can be made from 1, 2, 3, 4, 5, and 6 if letter A repetition is allowed and letter B repetition is not allowed.
This can be calculated by taking the number of possible combinations for each digit (6 for A, 5 for B, 4 for C) and multiplying them together: 6 x 5 x 4 = 120. Since there are 6 possible numbers for each digit, there are 120 combinations for a 3-digit number. Then, multiplying 120 by 6 (since repetition is allowed) yields 720 possible 3-digit numbers.

Question 4: Abstract Vector Spaces LetWbe the set of all vectorsu=(x,y)inR2such that the product of its componentsxandysatisfy the equationx⋅y=0. Check whether this set (a) is closed under operation of standard scalar multiplication in the plane. (b) is closed under operation of standard vector addition in the plane. Is the information you found is sufficient to conclude whether this set forms a vector space or not? Explain why yes or why not. What does this set represent geometrically?
The set W represents the x-axis and y-axis in the plane. Any vector with one of its components equal to 0 will satisfy the equation x⋅y = 0, and these vectors lie on either the x-axis or y-axis.
(a) The set W is closed under standard scalar multiplication in the plane. This is because for any scalar c and any vector u = (x,y) in W, the product of the components of cu = (cx,cy) is (cx)(cy) = c2(xy) = c2(0) = 0, so cu is also in W.
(b) The set W is not closed under standard vector addition in the plane. For example, the vectors u = (1,0) and v = (0,1) are both in W, but their sum u + v = (1,1) is not in W because the product of its components is 1(1) = 1, which does not satisfy the equation x⋅y = 0.
Since the set W is not closed under standard vector addition, it does not form a vector space. A set must be closed under both scalar multiplication and vector addition in order to be a vector space.
Geometrically, the set W represents the x-axis and y-axis in the plane. Any vector with one of its components equal to 0 will satisfy the equation x⋅y = 0, and these vectors lie on either the x-axis or y-axis.

Find the sides of a triangle circumscribed about a circle of
radius 4 and divided on one side by the circle into segments of
length 6 and 8.
The sides of the triangle circumscribed about a circle of radius 4 and divided on one side by the circle into segments of length 6 and 8 are 6, 8, and 4.
The triangle circumscribed about a circle of radius 4 and divided on one side by the circle into segments of length 6 and 8 can be found using the Law of Cosines. The Law of Cosines states that c2 = a2 + b2 - 2ab cos C, where c is the length of the hypotenuse, a and b are the lengths of the other sides, and C is the angle opposite side c.
We know the hypotenuse of this triangle is 8, as it is the length of one of the segments on the side of the triangle. We also know that angle C is 90° as it is a right triangle.
Therefore, using the Law of Cosines we can find the length of the other side of the triangle, which is 6. The equation is 82 = 62 + a2 - 2(6)(a)cos(90°). Solving this equation, we find that a = 4.
Therefore, the sides of the triangle circumscribed about a circle of radius 4 and divided on one side by the circle into segments of length 6 and 8 are 6, 8, and 4.

The wind farms in southern California contain wind generators whose power production varies directly with the cube of the wind's speed. one such generator produces 1000W of power in a 25mph wind, find the power it generate in a 35mph wind.
The wind generator will produce 2744W of power in a 35mph wind.
Determine the generate powerTo find the power generated by the wind generator in a 35mph wind, we can use the formula P = kV³, where P is the power generated, k is a constant, and V is the wind's speed.
First, we need to find the value of k. We can do this by plugging in the given values of P and V into the formula and solving for k:
1000W = k(25mph)³ 1000W = k(15625mph³)
k = 1000W/15625mph³
k = 0.064W/mph³
Now that we have the value of k, we can plug it back into the formula along with the new wind speed of 35mph to find the power generated:
P = (0.064W/mph³)(35mph)³
P = (0.064W/mph³)(42875mph³)
P = 2744W
Therefore, the wind generator will produce 2744W of power in a 35mph wind.
