Solved CS 214 Spring 2026 Project I: My little malloc()

For this assignment, you will implement your own versions of the standard library functions malloc() and free(). Unlike the standard implementations, your versions will detect common usage errors and report them. For this assignment, you will create 1. A library mymalloc.c with header mymalloc.h, containing the functions and macros described below. 2. A program memgrind.c that includes…

Solved CS766 Homework 7 Computer Vision, Spring 2026

Challenge 1: In this challenge you are asked to develop an optical flow system. You are given a sequence of 6 images (flow1.png – flow6.png) of a dynamic scene. Your task is to develop an algorithm that computers optical flow estimates at each image point using the 5 pairs (1&2, 2&3, 3&4, 4&5, 5&6) of consecutive images. Optical flow estimates can be computed using the optical flow constraint…

Solved CS766 Homework 6 Computer Vision, Spring 2026

Challenge 1: Your task is to develop an application that allows a user to refocus a scene. We will call it a refocusing app. In a conventional image, the focus of a scene is fixed at the time of capture. How can a refocusing app refocus a scene? The trick is that, instead of using a single image, a refocusing app uses a focal stack—a sequence of images captured at different focus settings—as an…

Solved CS766 Homework 5 Computer Vision, Spring 2026

Challenge 1: Your task is to develop a vision system that recovers the shape, surface normal and reflectance of an object. For this purpose you will use photometric stereo. You will be given 5 images of an object taken using five different light sources. Your task is to compute the surface normal and albedo for the object. For this purpose, however, you will need to know the directions and…

Solved CS766 Homework 4 Computer Vision, Spring 2026

Challenge 1: Your task is to develop an “Image Mosaicking App” that stitches a collection of photos into a mosaic. Creating image mosaics and panoramas have become one of the most popular features on smart phones. Outside of the realm of smart phones, similar applications have also been developed to create stunning panoramas seen on gigapan.org. With the concepts and algorithms presented in…

Solved CS766 Homework 3 Computer Vision, Spring 2026

Challenge 1: Your task is to develop a vision system that recognizes lines in an image using the Hough Transform. We will call it the “line finder.” Test your line finder on these three images: hough_1.png, hough_2.png and hough_3.png. The line finder pipeline is divided into four sub-parts, each corresponding to a program you need to write and submit. a. First, you need to find the edge pixels…

Solved CS766 Homework 2 Computer Vision, Spring 2026

Challenge 1: Your task is to develop a vision system that recognizes two dimensional objects in images. For example, we might be interested in detecting the two objects shown in two_objects.png in another image such as many_objects_1.png. The vision system should not only determine whether the objects are present in the image, but also compute their positions and orientations. The recognition…

Solved CS766 Homework 1 Computer Vision, Spring 2026

Programming Walkthrough: These are “lightweight” programming assignments, which essentially walk you through partially complete code and ask you to fill in the missing segments. These assignments are designed with the following two goals: 1) to help you get started with Python (if you are not yet familiar with it), 2) to demonstrate some of the important concepts discussed in class in…

Solved CS 639 Spring 2026 HW 5: Alignment

In this assignment, you will build a preference-based alignment pipeline for a small decoder-only transformer. The task is a controlled knowledge-seeking QA problem: when the context contains evidence, the model should answer correctly; when the evidence is missing, the aligned model should abstain with “I don’t know.” You will implement the key objectives behind supervised fine-tuning (SFT),…

Solved [CS639] HW4 Fine-Tuning Assignment Spring 2026

1 Baseline Full Fine-Tuning 1.1 Setup The NLI dataset we will use for this assignment is SNLI, loaded via the HuggingFace datasets library. Each example has a premise, a hypothesis, and a label (0 = entailment, 1 = neutral, 2 = contradiction). Examples with label −1 (annotator disagreement) should be filtered out. The primary model is DistilBERT (distilbert-base-uncased), but you may use any…

Solved [CS639] Homework 3 Spring 2026

1 VIT 1.1 Setup The image data we will use for this homework is CIFAR100. The code used to create the dataset objects is already included in the notebook. Also provided is code for attention and transformer blocks. 1.2 [Code] VIT Implementation (15 points) The transformer building blocks are provided for you in this homework. It is recommended you look at the TransformerBlock class, which now has…

Solved CS 639 Spring 2026 HW 2: Transformers

In this assignment, you will build a small GPT-style language model from scratch, training it to speak Shakespearean. You will implement core transformer components like scaled dot-product attention, multi-head attention, and a full transformer block; train your model on a character-level text corpus; and run ablation experiments to understand why each component matters. You will also explore the…

Solved CS 639 Assignment 1: Neural Network Fundamentals Spring 2026

In this assignment, you will be implementing a classic feed-forward neural network from scratch. You will then perform a variety of experiments by varying the training dataset and hyperparameters, creating plots and writing analyses of what you observe. You are expected to submit the following: ● Your codebase as a .zip directory. Your codebase can be structured however you choose, however please…

CPSC1520 JavaScript 1 Exercise: Developer Console and Intro to JavaScript Solved

Introduction The console is a great tool to see what’s going on on the page and will also be how we debug our JavaScript throughout the course. It allows us to execute statements on the page (like we’ve seen in class) in real time! In this first lab assessment, you will try fixing typos on our page in the console first; second, you will put all of these changes in your main.js; and third, you…

Com S 2280 Project 4: Archived Message Reconstruction Solved

1. Problem Description The objective of this exercise is to reconstruct/unzip a message archived with a binary-treebased algorithm. The program should receive a file name as a single command-line argument. It should then decode the message in the file and print it out to the console. The name of the compressed message file will end in .arch, e.g. “monalisa.arch”. The file consists of two or three…
