Q1 HMMs, Part I 20 Points Consider the HMM shown below. The prior probability , dynamics model , and sensor model are as follows: We perform a first dynamics update, and fill in the resulting belief distribution . We incorporate the evidence . We fill in the evidence-weighted distribution , and the (normalized) belief distribution . You get to perform the second dynamics update. Fill in the resulting belief distribution . .80 .20 P(X0 ) P(X ∣ t+1 Xt) P(E ∣ t Xt) B (X ) ′ 1 E...

Submit your predictions for the test sets to Kaggle as early as possible. Include your Kaggle scores in your write-up (see below). The Kaggle competition for this assignment can be found at: • • 2. Submit a PDF of your homework, with an appendix listing all your code, to the Gradescope assignment entitled “HW3 Write-Up”. You may typeset your homework...

CS 189/289A Introduction to Machine Learning Spring 2021 Jonathan Shewchuk HW2: I r Math Due Wednesday, February 10 at 11:59 pm • Homework 2 is an entirely written assignment; no coding involved. • We prefer that you typeset your answers using LATEX or other word processing software. If you haven’t yet learned LATEX, one of the crown jewels of computer science, now is a good time! Neatly handwritten and scanned solutions will also be accepted. • In all of the questions, show your ...

The amount of space on each side of a typical surface water that must serve as a buffer zone? correct answer: 30ft The amount of space on each side of a sensitive water body that must serve as a buffer zone? correct answer: 45ft Which option provides the entire buffer width? correct answer: Option A Which option provides a reduced buffer width? correct answer: Option B Which option provides no buffer zone? correct answer: Option C Which BMP cannot be used for velocity control...

CS 189 Introduction to Machine Learning Spring 2021 HW6 Due: Wednesday, April 21 at 11:59 pm Deliverables: Neural network libraries such as Tensorflow and PyTorch have made training complicated ne ural network architectures very easy. However, we want to emphasize that neural networks begin with fundamentally simple models that are just a few steps removed from basic logistic regression. In this assignment, you will build two fundamental types of neural network models, all in plain numpy: a feed...

Question 1 Behind the Scenes The vulnerability occurs in deja_vu function, where a malicious attacker can input more than 8 characters, which will cause buffer overflow of buffer “door.” void deja_vu() { char door[8]; gets(door); // where buffer overflow occurs } The info frame in the deja_vu function gives me this result: (gdb) i f Stack level 0, frame at 0xbffff800: ... Saved registers: ebp at 0xbffff7f8, eip at 0xbffff7fc (gdb) p &door $1 = (char (*)[8]) 0xbffff7e8 He...
