CISC520 Data Engineering and Mining
Task description: The data set comes from the Kaggle Digit Recognizer competition. The goal is to recognize digits 0 to 9 in handwriting images. Because the original data set is large, I have systematically sampled 10% of the data by selecting the 10th, 20th examples and so on. You are going to use the sampled data to construct prediction models using multiple machine learning algorithms that we have learned recently: naïve Bayes, kNN and SVM algorithms. Tune their parameters to get the best model (measured by cross-validation) and compare which algorithms provide a better model for this task. Report structure: Section 1: Introduction Briefly describe the classification problem and general data pre-processing. Note that some data pre-processing steps may be specific to a particular algorithm. Report those steps under each algorithm section. Section 3: Naïve Bayes Build a naïve Bayes model. Tune the parameters, such as the discretization options, to compare results. Section 3: K-Nearest Neighbour method section 4: Support Vector Machine (SVM)Section 4: Algorithm performance comparison Compare the results from the two algorithms. Which one reached higher accuracy? Which one runs faster? Can you explain why?
Advanced Tasks-Turing Test
a) In the appendix to this lab sheet and as support materials on Moodle there are two transcripts of Turing Tests. On the left of each transcripts the interaction between the judge and one hidden entity and on the right is the interaction between the judge and the second hidden entity. These interactions happen at the same time.
Review the two Turing Test transcripts and analyse the question-answer sequences between a human interrogator and two hidden entities in two different simultaneous comparison Turing tests from actual Turing test experiments (Transcript One - 2008 loebner Prize at Reading University; Transcript Two - Turing100 at Bletchley Park in 2012).
Explain if your feel that the hidden entities in these two transcribes meet Turing’s criteria of answering the Interrogators questions in a satisfactory manner. (up to 100 word)
Please explain in up to 50 words whether the hidden entities in these two transcripts being questioned in parallel by the human interrogator, are:
One human and one machine? If so, which is which (left right)? Two humans? Two machines?
b) If you created a Chatbot, what strategy would you use to convince the judge that they are talking to a human? You should give at least 2 example responses to human input based on your strategy. The human inputs could be: “How are you?”, “What year is it?”, “Where are you?”, “Are you a robot?”, Are you human?’ (Up to 50 word)
