forward propagation is simply the summation of the previous layer's output multiplied by the weight of each wire, while back-propagation works by computing the partial derivatives of the cost function with respect to every weight or bias in the network. in back propagation, the network gets better at minimizing the error and predicting the output of the data being used for training by incrementally updating their weights and biases using stochastic gradient descent. we are trying to estimate a continuous-valued function, thus we will use squared loss as our cost function and an identity function as the output activation function. is the activation function that is called on the input to our final layer output node, and is the predicted value, while is the actual value of the input. (6.1) (6.2) when you're done implementing the function train (below and in your local repository), run the script and see if the errors are decreasing. if your errors are all under 0.15 after the last training iteration then you have implemented the neural network training correctly. you'll notice that the train function inherits from neuralnetworkbase in the codebox below; this is done for grading purposes. in your local code, you implement the function directly in your neural network class all in one file. the rest of the code in neuralnetworkbase is the same as in the original neuralnetwork class you have locally.
First, you will need to connect a sonar range finder sensor to the Raspberry Pi. The sensor should have two pins, one for the trigger and one for the echo signal. You will need to connect the trigger pin to a GPIO output pin on the Raspberry Pi and the echo pin to a GPIO input pin.
Next, you will need to write a C program that interacts with the GPIO pins to control the sonar range finder. You can use the sysfs interface to access the GPIO pins. This interface provides a file system-like interface to the GPIO pins, allowing you to read and write values to the pins using standard file I/O operations.In your program, you will need to initialize the trigger pin as an output and the echo pin as an input using the gpio_output() and gpio_input() functions, respectively. Then you can set the trigger pin high and low to send a pulse to the sensor. You will need to zero a count variable and enter a while loop that waits until the echo signal goes high. Once the echo signal goes high, you can exit the loop and enter another while loop that waits until the echo signal goes low. Inside this loop, you can increment the count variable. Once the echo signal goes low, you can exit the loop and the count value will be proportional to the distance traveled by the sonar pulse. You can print the raw count value and convert it to a distance using empirical means.It is important to note that the actual code implementation will depend on the specific sonar range finder sensor and the GPIO pins used on the Raspberry Pi. You may need to consult the datasheets and manuals for the sensor and the Raspberry Pi to determine the appropriate GPIO pins to use and the specific GPIO commands to send.

You can define a function without calling it. (T/F)
True. A function can be defined without being called. It will only be executed when it is called in the program. Defining a function involves specifying the function name, input parameters, and the actions to be performed when the function is called.
Once defined, the function can be called multiple times in the program. Function definition is an important concept in programming. It allows developers to break down a complex problem into smaller, more manageable tasks that can be implemented as separate functions. This not only simplifies the programming process but also makes the code more modular and easier to maintain. Additionally, defining a function without calling it can be useful for testing or debugging purposes, as it allows developers to check the function's implementation before integrating it into the larger program.

If a film shows marks every 1 1/2 inches after it has been developed, what should the operator do to correct the problem
If a film shows marks every 1 1/2 inches after it has been developed, the operator needs to identify the root cause of the problem and take corrective action. One of the possible reasons for these marks could be the presence of dirt or debris on the film, causing a physical obstruction during the development process.
To correct this problem, the operator needs to carefully inspect the film before processing it to ensure it is free from any physical debris or marks. Additionally, the operator should clean the processing equipment, including the rollers and tanks, to prevent any contaminants from getting onto the film. If the problem persists, the operator may need to adjust the processing parameters, such as the temperature or agitation of the solution, to ensure even and consistent development of the film. It is also possible that the film itself is damaged or defective, in which case the operator should discard it and use a new roll. Overall, the key to correcting this problem is careful attention to detail and a thorough understanding of the film development process. By identifying the root cause and taking appropriate corrective action, the operator can ensure that the film is of the highest quality and free from any defects or marks.

The class provided by the Java API for handling strings is named _________ Recall that __________ data type variables (such as an int and double variables) hold the actual data item with which they are associated A class type variable (such as a String variable) holds the ____________ I of the data item with which it is associated.
The class provided by the Java API for handling strings is named "String". Recall that "primitive" data type variables (such as an int and double variables) hold the actual data item with which they are associated. A class type variable (such as a String variable) holds the "reference" of the data item with which it is associated.
Recall that primitive data type variables (such as int and double variables) hold the actual data item with which they are associated. For example, an int variable might hold the value 5 or 10. A double variable might hold the value 3.14 or 2.71828. A class type variable (such as a String variable) holds the reference of the data item with which it is associated. The reference is an address in memory where the actual data is stored. For example, a String variable might hold a reference to a sequence of characters like "Hello, World!". The String variable does not hold the actual sequence of characters itself; instead, it holds a reference to the location in memory where the characters are stored. This difference is important because it affects how variables are passed around and manipulated in Java. When a primitive data type is passed to a method or assigned to a new variable, a copy of the actual data is made. When a class type variable is passed to a method or assigned to a new variable, a copy of the reference is made. This means that changes made to the data through one variable will be reflected in all other variables that reference the same data.

If an Agile team planned to complete 30 story points in an iteration but worked at only 83% of the rate planned. What is the project's SPI?
The SPI (Schedule Performance Index) is a measure of the project's progress in relation to its planned schedule. It is calculated as the ratio of the Earned Value (EV) to the Planned Value (PV).
In this case, the team planned to complete 30 story points in the iteration, which is the PV. However, they worked at only 83% of the rate planned, which means they completed 83% of the planned work. Therefore, the Earned Value (EV) is 0.83 * 30 = 24.9.
The SPI can now be calculated as:
SPI = EV / PV = 24.9 / 30 = 0.83
Therefore, the project's SPI is 0.83, which indicates that the team is completing work at a slower rate than planned.
