In a 384-well plate luciferase assay, we drugged 4 receptors (A, B, C, D) with their endogenous agonists at a range of doses. Below is a subset of the resulting data frame (please use the full data frame attached to the original email as a CSV file). Each row of this data frame corresponds to a single well of the 384 well plate. The columns are as follows: receptor: the receptor tested in the well agonist: the endogenous agonist used for a receptor agonist_nM: the dose of the endogenous compound (in nanomolar) ● RLU: raw luminescence of the well (our measure of receptor activity) To answer this 3 part question, we’ll ask you to submit a PDF file containing all of your source code, plots, and written interpretation. (Using something like a Jupyter Notebook with Python or Rmarkdown is recommended, but not required.) You should provide brief explanations of your thought process at each step. Part A: Different receptors have different basal rates of activity. To better facilitate…
Assignment Consider the Bayes network below, defined over four Boolean variables X1 X2 X3 Х4 • How many parameters are needed to define P(X1, X2, X3, X4) for this Bayes Net? • Give the formula that calculates P(X1 = 1, X2 = 0, X3 = 1, X4 = 0) using only the Bayes net parameters. Use notation like P(X1= 0|X2 = 1, X4 = 0) to refer to each Bayes net parameter you use in your formula. • Give the formula that calculates P(X1=1,X4=0) using only the Bayes net parameters. • Give the formula that calculates P(X2=1|X3 = 0) using only the Bayes net parameters.

Suppose you are given a document of four words {w1, w2, w3, w4}, where w1, w2 are topic words; w3 and w4 are background words. Moreover, count(w1) = count(w3) = 4, and count(w2) = count(w4) = 2. Suppose that the background distribution is given below: Word w W1 w2 w3 W4 p(w|0g) 0.1 0.1 0.5 0.3 Suppose that the EM algorithm generates the following values at the current iteration: Word w W1 w2 w3 W4 p(w|0) 0.44 0.22 0.20 0.14 What are the values of p(w 0) at the next iteration?
Instrument FrequencyCounter to use Stopwatch and StdDraw to create a plot with the x-axis representing the number of get() or put() calls and the y-axis representing total running time, with a point plotted representing the cumulative time after each call. Run your Tale of Two Cities programme using SequentialSearchST and then BinarySearchST, then discuss the results. Caching may explain sharp leaps in the curve, which is beyond the scope of this question.

A 120 x 120 image, g[x, y], has an FOV of 10 cm x 10 cm. What is the value of fr (in the units of 1/cm) for the entry in the bottom-right corner of G[fz, fy]. Round your answer to two digits after the decimal. Note, G[f, fy] is the 2D DFT of g(x, y]. You may assume the indexing convention of MATLAB, where the indices increase from top to bottom and left to right. As we did in the class, you may assume that the center (zero-frequency location) of G[fz, fy] is at [61, 61].

Mean Squared Error (MSE ) is one of the metrices that is used to evaluate the performance of a given model. MSE is very simple to calculate, it represents the difference between the actual and predicted values extracted by squared the average difference over the data set. Simply, the MSE is calculated as follow: ( 1/n) * Σ(Υ - x2 MSE = • X array of the actual values • Y array of the predicted values • E: A symbol that means "sum". • n: number of the values Write a python code to calculate the MSE. The python code should: 1/ Create X and Y NumPy arrays. 2/ Create a new NumPy array "Diff" which is the difference between the two arrays X and Y. 3/ Create a new NumPy array "Sqd" which is squared of "Diff" array values (loop is not allowed). 4/ Calculate "sum" which is the summation of the "Sqd" array values (loop is not allowed). 5/ Print the MSE, which is the division of the sum by the number of values in Y. Example: X= [123 3] Y = [504 3] Diff = [4 -2 1 0] Sqd = [16 4 1 0] sum =…
