Lab 2 MSc: Time Series Prediction with GP

You need to implement one program that solves Exercises 1-3 using any programming language. In Exercise 5, you will run a set of experiments and describe the result using plots and a short discussion.

(In the following, replace abc123 with your username.) You need to submit one zip file with the name niso3-abc123.zip. The zip file should contain one directory named niso3-abc123 containing the following files:

? the source code for your program
? a Dockerfile (see the appendix for instructions) ? a PDF file for Exercises 4 and 5

1

In this lab, we will do a simple form of time series prediction. We assume that we are given some historical data, (e.g. bitcoin prices for each day over a year), and need to predict the next value in the time series (e.g., tomorrow’s bitcoin value).

We formulate the problem as a regression problem. The training data consists of a set of m input vectors X = (x(0), . . . , x(m−1)) representing historical data, and a set of m output values Y=(x(0),…,x(m−1)),whereforeach0≤j≤m−1,x(j) ∈Rn andy(j) ∈R. Wewillusegenetic programming to evolve a prediction model f : Rn → R, such that f(x(j)) ≈ y(j).

Candidate solutions, i.e. programs, will be represented as expressions, where each expression eval- uates to a value, which is considered the output of the program. When evaluating an expression, we assume that we are given a current input vector x = (x0 , . . . , xn−1 ) ∈ Rn . Expressions and eval- uations are defined recursively. Any floating number is an expression which evaluates to the value of the number. If e1, e2, e3, and e4 are expressions which evaluate to v1, v2, v3 and v4 respectively, then the following are also expressions

• ? (add e1 e2) is addition which evaluates to v1 + v2, e.g. (add 1 2)≡ 3
• ? (sub e1 e2) is subtraction which evaluates to v1 − v2, e.g. (sub 2 1)≡ 1
• ? (mul e1 e2) is multiplication which evaluates to v1v2, e.g. (mul 2 1)≡ 2
• ? (div e1 e2) is division which evaluates to v1/v2 if v2 ̸= 0 and 0 otherwise, e.g., (div 4 2)≡ 2, and (div 4 0)≡ 0,
• ? (pow e e ) is power which evaluates to vv2 , e.g., (pow 2 3)≡ 8 121
• ? (sqrt e1) is the square root which evaluates to √v1, e.g.(sqrt 4)≡ 2
• ? (log e1) is the logarithm base 2 which evaluates to log(v1), e.g. (log 8)≡ 3
• ? (exp e1) is the exponential function which evaluates to ev1 , e.g. (exp 2)≡ e2 ≈ 7.39
• ? (max e1 e2 ) is the maximum which evaluates to max(v1 , v2 ), e.g., (max 1 2)≡ 2
• ? (ifleq e1 e2 e3 e4) is a branching statement which evaluates to v3 if v1 ≤ v2, otherwise the expression evaluates to v4 e.g. (ifleq 1 2 3 4)≡ 3 and (ifleq 2 1 3 4)≡ 4
• ? (data e1) is the j-th element xj of the input, where j ≡ |⌊v1⌋| mod n.
• ? (diff e1 e2) is the difference xk −xl where k ≡ |⌊v1⌋| mod n and l ≡ |⌊v2⌋| mod n
• ? (avg e1 e2) is the average 1 ?max(k,l)−1 xt where k ≡ |⌊v1⌋| mod n and l ≡ |⌊v2⌋| |k−l| t=min(k,l)

mod n
In all cases where the mathematical value of an expression is undefined or not a real number (e.g.,

−1, 1/0 or (avg 1 1)), the expression should evaluate to 0.

We can build large expressions from the recursive definitions. For example, the expression

` (add (mul 2 3) (log 4)) `

2

evaluates to

2·3+log(4) = 6+2 = 8.
To evaluate the fitness of an expression e on a training data (X,Y) of size m, we use the mean

square error

f(e)=m

j=0

m−1
1 ? ? (j) (j) ?2

y −e(x ) ,
where e(x(j)) is the value of the expression e when evaluated on the input vector x(j).

Exercise 1. (30 % of the marks)

Implement a routine to parse and evaluate expressions. You can assume that the input describes a syntactically correct expression. Hint: Make use of a library for parsing s-expressions1, and ensure that you evaluate expressions exactly as specified on page 2.

Input arguments:

? -expr an expression
? -n the dimension of the input vector n ? -x the input vector

Output:
? the value of the expression

Example:

` [pkl@phi ocamlec]\$ niso_lab3 -question 1 -n 1 -x "1.0"  -expr "(mul (add 1 2) (log 8))" `
` 9.0 [pkl@phi ocamlec]\$ niso_lab3 -question 1 -n 2 -x "1.0 2.0"  `
` -expr "(max (data 0) (data 1))" `

2.0

Exercise 2. (10 % of the marks) Implement a routine which computes the fitness of an expression given a training data set.

Input arguments:

• ? -expr an expression
• ? -n the dimension of the input vector
• ? -m the size of the training data (X,Y)
• ? -data the name of a file containing the training data in the form of m lines, where each line contains n + 1 values separated by tab characters. The first n elements in a line represents an input vector x, and the last element in a line represents the output value y.Output:
? The fitness of the expression, given the data.1See e.g. implementations here http://rosettacode.org/wiki/S-Expressions4

Exercise 3. (30 % of the marks)
Design a genetic programming algorithm to do time series forecasting. You can use any genetic

operators and selection mechanism you find suitable. Input arguments:

• ? -lambda population size
• ? -n the dimension of the input vector
• ? -m the size of the training data (X,Y)
• ? -data the name of a file containing training data in the form of m lines, where each line contains n + 1 values separated by tab characters. The first n elements in a line represents an input vector x, and the last element in a line represents the output value y.?
• -time budget the number of seconds to run the algorithm Output:? The fittest expression found within the time budget
• .Exercise 4. (10 % of the marks)
• Describe your algorithm from Exercise 3 in the form of pseudo-code. The pseudo-code should besufficiently detailed to allow an exact re-implementation.
• Exercise 5. (20 % of the marks)
• In this final task, you should try to determine parameter settings for your algorithm which lead toas fit expressions as possible.Your algorithm is likely to have several parameters, such as the population size, mutation rates, selection mechanism, and other mechanisms components, such as diversity mechanisms.Choose parameters which you think are essential for the behaviour of your algorithm. Run a set of experiments to determine the impact of these parameters on the solution quality. For each parameter setting, run 100 repetitions, and plot box plots of the fittest solution found within the time budget.

## gt.pl

Write a perl program that contains a subroutine that returns the greater of two numbers passed to it. The program should print out the two numbers that will be passed to the subroutine and then call the subroutine, passing those 2 numbers to it. The subroutine should determine if one number is greater than the other and return to the main routine the larger number so that the main routine can print out a message about which number is greater. In other words, if num1 was greater than num2, then the subroutine should return num1 to the main program and a message about num1 being greater would be printed out to the user. Otherwise, num2 should be returned and a similar message about num2 should be printed.

## Double_the_number.pl

Write a perl program that reads in a text file containing several numbers in it. The program should loop through all the numbers, printing out the original number and then multiplying it by 2 and printing out that doubled number.

## Advanced C++ question Computer Science Assignment Help

The purpose of this assignment is to maintain a list of 10 highest scores for some game. The assignment requires building and using two libraries and reading and writing a binary file. The program will make use of an input file containing game scores.

#### The Date Library

The Date library should contain a Date class. The Date class should contain a time_t data member to store the date.
The Date class should contain

• 4 constructors:
• Date();
• Date(const Date&) = default;
• Date(time_t); // Date in time_t format
• Date(const char*);
• The default constructor should create a Date object containing the current date.
• Date(const char*) constructor should accept arguments with date formats of “mm/dd/yy”, or “mm-dd-yy” or “ddmonyy”
• The Date library should also contain an overloaded insertion operator to display Dates.
• You may add any other member function necessary for the Date class.

#### The Score library

The Score library should contain a Score class and an overloaded insertion operator to display Score objects.
The Score class shold contain

• 3 data members:
• char name[16];
• int score;
• Date date;
• One or more constructors
• Accessor functions
• An overloaded < operator function. You’ll need this to sort the Scores.

#### The binary file

The Scores data must be stored in a binary file in sorted order.
A maximum of 10 highest scores will be stored in the binary file.
The binary file should be read in before each record in the input file is processed.

The binary file should be written each time a new score is inserted into the list of highest scores.

Sample input, output, and main are attached

## Advanced C++ assignment Computer Science Assignment Help

1. You are to use the Word and Dictionary classes defined below and write all member functions and any necessary supporting functions to achieve the specified result.
2. The Word class should dynamically allocate memory for each word to be stored in the dictionary.
3. The Dictionary class should contain an array of pointers to Word. Memory for this array must be dynamically allocated. You will have to read the words in from the file. Since you do not know the “word” file size, you do not know how large to allocate the array of pointers. You are to let this grow dynamically as you read the file in. Start with an array size of 8, When that array is filled, double the array size, copy the original 8 words to the new array and continue. You can see the expected behavior in the sample program output listed below.
4. You can assume the “word” file is sorted, so your Dictionary::find() function must contain a binary search algorithm. You might want to save this requirement for later – until you get the rest of your program running.
5. Make sure you store words in the dictionary as lower case and that you convert the input text to the same case – that way your Dictionary::find() function will successfully find “Four” even though it is stored as “four” in your Dictionary.
6. Make sure you remove leading or trailing punctuation from a word, such as “nation,”.
7. Do not use the string class for this assignment. All text data should be stored and managed as C-strings.

Warning: If you are using a Mac or Linux compiler, you may want to remove the r at the end of each line in both input files. You can do that like this:

strtok(line,”r”);

`<strong><u>Word class</u></strong> class Word  {  char* word_;  public:  Word(const char* text = 0);  ~Word();  const char* word() const;  };  <strong><u>Dictionary class</u></strong> class Dictionary  {  Word** words_;  unsigned int capacity_; // max number of words Dictionary can hold  unsigned int numberOfWordsInDictionary_;  void resize();  void addWordToDictionary(char* word);  public:  Dictionary(const char* filename);  ~Dictionary();  bool find(const char* word); };  <strong><u>main()</u></strong>  int main() { char buffer[MaxWordSize]; Dictionary Websters(wordfile); ifstream fin(document); cout << "nSpell checking " << document << "nn"; while (fin >> buffer) { // remove leading/trailing punctuation, change to lowercase if (cleanupWord(buffer)) {  if (!Websters.find(buffer)) { cout << buffer << " not found in the Dictionaryn"; } } } }  <strong><u>Program output</u></strong>  Dictionary resized to capacity: 16 <strong><--- This illustrates Dictionary resizing</strong> Dictionary resized to capacity: 32 Dictionary resized to capacity: 64 Dictionary resized to capacity: 128 Dictionary resized to capacity: 256 Dictionary resized to capacity: 512 Dictionary resized to capacity: 1024 Dictionary resized to capacity: 2048 Dictionary resized to capacity: 4096 Dictionary resized to capacity: 8192 Dictionary resized to capacity: 16384 Dictionary resized to capacity: 32768  Spell checking /deanza/data/gettysburg.txt <strong><--- spell checking begins</strong>  created not found in the Dictionary <strong><--- words not found in the Dictionary</strong> struggled not found in the Dictionary consecrated not found in the Dictionary por not found in the Dictionary remember not found in the Dictionary unfinished not found in the Dictionary nobly not found in the Dictionary advanced not found in the Dictionary ...`
