This repository contains my lecture notes and assignment submissions made in the course CS771 (2022-23 Sem. I) in a team of 5. Our team name was ML Class of '14 with the team members:
| Name | User ID |
|---|---|
| Kunwar Preet Singh | Enkryp |
| Parinay Chauhan | parinayc20 |
| Pratyush Gupta | PratyushGupta0 |
| Akhil Agrawal | akhilagrawal1001 |
| Aditya Tanwar (me) | cliche-niche |
A major component of my notes were made from the slides of discussion sessions taken by Prof. Purushottam Kar, along with the videos uploaded on the course's YouTube channel. The slides are available on the course website [IIT-K intranet/ VPN required].
The notes had to be split into two parts due to size constraints of files. The first half almost corresponds to content covered upto and including the 7th discussion session, while the second half contains the rest.
In each assignment, we were given a problem statement after being taught some methods/models:
- Assignment 1: Exercise on using SVMs. We explored SGDM to solve it, but ended up submitting SCDM with a bunch of case-specific optimizations.
- Assignment 2: The problem was that of multilabel classification, with complete freedom to use whatever one wants. Our group ended up using a mix of Decision Trees, and Neural Networks.
- Assignment 3: The problem required the usage of Computer Vision followed by Deep Learning, specifically CNNs, to infer greek alphabets written in a CAPTCHA. A perfectly arbitrary captcha has been provided here.
Note: We were provided with 2000 sample images for A3 but to save space on this repository, a single image has been provided.
- A1: 66/60 - 7 marks bonus for using reduced dimensionality (
<200) and 1 mark deducted fort=0.2sand0.01<=e=0.04<1(full marks fore<0.01) - A2: 87/100 - 6 marks deducted for a size of
~7.5 MB(full marks for<128 KB), 6 marks deducted for an inference time of~2s(ceil( max( 1 - t, 0.4 ) * 10 )), 1 mark deducted formprec@1 = 0.625(ceil( max( p, 0.4 ) * 5 )) - A3: 89/100 - 6 marks deducted for a size of
~11.6 KB(full marks for<128 KB), 4 marks deducted for an inference time of~30s(full marks for<5s), 1 mark deducted for inaccuracy (floor( c * 40 ))
- The course website can be found here [Intranet required].
- This repository has been forked from Kunwar's repository. Naturally, there are a lot of similarities between the two, except for the readme and the notes section.
- Kunwar Preet "Enkryp" Singh for Assignments 1 and 2 (and the bonus 7 marks!)
- Pratyush "PratyushGupta0" Gupta for Assignment 3.
