Graduate Project:
Submissions includes proposal, intermediate presentation+report, final presentation+report. Details will be posted later. I value your efforts and learning than your results. However, good results may lead to publication.
Project proposal (define the project’s scope, describe your current understanding of the project, its input-output, data source and data augmentation, expected results, references, possible code-source, etc.) is due Feb 5/F’21. Do not copy/paraphrase from past projects.
1. Indus-Valley Civilization OCR with deep learning.
Twenty-six original IVC-images are there in the zip directory.
Train a model to detect the bounding boxes for Graphemes (characters) in the text.
(Similar to SVHN project: , Goodfellow’s (2013) work and google up on Detecto project.)
You will need to create labels first by creating bounding boxes around each grapheme in original images. See:
/Fall2020/murrayjordan_1830146_42861297_Fa20_IRVC_MurrayNguyen.zip
This group used Detecto pre-trained model. I am not sure it is flexible enough for our purpose. Also, they had trouble understanding data augmentation requirements. Do not do too much rotation, low angle rotation is good enough (mimicking an archaeologist taking picture in the field). Rather, include small 3D rotation, if you can.
You will need to augment data for creating large enough training set from 22 original images (some set aside for validation). Augmentation should be with low angle rotation and scaling in 3D. Imagine an archeologist taking a picture of a tablet in the field. A relevant code is in: /Fall2020/sp20_motif_Qi_mike(1).7z
This previous group used RetinaNet, but they only created bounding box around the whole text, rather than each grapheme/character. Also, they used reflection for data augmentation that is meaningless for us.
Additional image resources from Asko Parpola’s corpus:
Two volumes of Parpola's collections seem available from ASI as e-books. Here they are:
This also means, ASI is likely to have the authority to provide us permission.
Otherwise, I am more confident now to obtain permission from the publisher.
The third volume is in print, so, possibly some libraries will have it around.
You may like to check this paper too: “Deep Learning the Indus Script.” Satish Palaniappan1, Ronojoy Adhikari. PLOS submission, arXiv:1702.00523v1 [cs.CV] 2 Feb 2017.
Tons of images here below, you need to extract them. Ignore the document’s dictionary.
cs.fit.edu/~dmitra/ArtInt/2021Spring/INDUS SCRIPT DICTIONARY-HARDBOD.pdf
This report was not on OCR, but had some proposed-Unicode for a few characters: Report_IndusValleyScript_FnlProjRep_AleeshaMishra_RahulDevMishra.pdf
I also downloaded Indus Script’s Unicode. Here it is: IndusUnicode-n1959.pdf
3/9/T: Expecting to see input data ready and some code output
3/12: Two routes, 1- use R-CNN code for 4-corner bounding box, 2- use x% overlap (say, 20%) for quality control on rectangular bounding box. I recommend the second option. At Inference do not provide too-much-rotated images. Primary objective for you should be not bounding box detection, but OCR.
Group 1. Peter Thomas pthomas2019
Brad Costa (wants IVC) bcosta2017
3/12: Detect single IVC characters. Choose 5 of them (plus unknown) for recognition. You need large augmented data set after you crop those 5+1 types of characters from images. No bounding box detection for you.
Group 2. Michael Hon mhon2014
Paloma Achu pvela2016
2. English handwriting optical character recognition with deep learning. Many commercial tools are available. You may explore and report on them, if free trials are available. However, you should use some free code/model to adapt for your project.
3/9/T: Expecting to see input data ready and some code output
3/12: Absent Sheetal. Present at 7:30pm on 3/16/T, before class.
Group 3. Parth Panchal ppanchal2021
Sheetal Ghodake sghodke2020
3. Bio-sequence prediction with Hidden Markov Model (HMM). Use an HMM tool to predict protein or nucleic-acid sequences. Evolution of SARS-CoV-2 is not very rapid (compared to, say, flu virus). Yet, it does evolve. Predicting future sequences may help vaccine developments. An HMM may be trained from existing sequences to predict new sequences with the model. Read up a little bit about gene, nucleotide sequences, and protein (amino acid sequence). Here is a report from the last semester: /Fall2020/ProjectFinalReport-CSE5400.docx However, you do not have to use the same sequences he used. For example, you may use evolution of SARS-CoV-2 genes, especially, the receptor-binding-domain, or flu-virus genes, or HIV. Dig up for such sequence databases.
3/9/T: Expecting to see input data ready and specific generative HMM implementation to work with for new sequence prediction
3/12/R: Data choice looks good to me. Get an HMM working!
3/25/R: Make generative HMM for sequence prediction. You can try that on some simple English words! Developing a validation regime needs deep thinking!
Group 4. Blake Janes bjanes2013@my.fit.edu
James Riswick-Esttelle jriswickeste2018@my.fit.edu
4. Affine motion modeling with deep learning. A 2D object gets translated, rotated, or scaled over time that is periodic: frequency higher than that of sampling, and low amplitude. Resulting image is blurred from motion. Train a CNN model for each transformation type, to predict the motion model parameters: direction and frequency. You will need image generator to create data sets. OpenCV / PILO may have affine transformation generators, but you need to create periodic motion with them. Little advanced: produce the motion free original image, in addition to estimating motion-model parameters.
The original image to work with is here: /2021Spring/Heart_image_82.png
A nice tutorial here, but do not use this code, as yours should be neural network based:
3/9/T: Expecting to see input motion data ready with ground truth, & network structure (input-output layers)
3/12/R: I recommended dropping milestones 3 and 4. Focus on periodic motion parameter’s detection.
3/26/F: Do forget about periodicity.
I was thinking deeper about affine-parameter detection.
You can train from a single input (layer) image, rather than two images.
The training set should contain images with parameter=0, and those with non-zero.
The output, of course, looks like non-zero (x,y) for translation, (theta, +/-) for rotation, and (lambda, +/-) for scaling.
Let me know for more clarification.
Group 5. Fred Gamble fgamble2021@my.fit.edu
Chris Millsap (merge with the above group) cmillsap2013@my.fit.edu
5. Recoding UNITY game engine to apply Genetic Algorithm for optimal rocket landing on lunar surface
3/12/R: No recommendation. Great job! Full group should present. Task sharing between partners.
Group 6. Michael Hoadley mhoadley2018@my.fit.edu
David Nieves-Acaron dnievesacaro2018@my.fit.edu

Special undergraduate project / Junior Design project: Submissions and deadlines will be the same as for the graduate students as above.
Some conscious patients in ICU can hear but cannot speak, often because of partial paralysis or tubings/masks in mouth and nose. Some of these patients die without being capable of communicating. Can we understand at least a few words of them from their EEG signals?
Task: train a deep learning model with brain EEG signals to understand a small fixed set of words or phonemes from whispers or loud thoughts.

(1) Search for 2) such systems of your choice and store them with your knowledge base and to answer queries. One of the systems would be simple “burglar alarm” example from that you can hand-compute for debugging your system. Get started with Ch 13 (my slides on probabilistic reasoning) before we cover that material in class.
Phase 1: 1.1. (DUE: 3-1-2021-M-11:59pm) Implement first a layered DAG in an object-oriented fashion in any language of your choice. Your code will input: number of nodes, nodes as Boolean variables, arcs, and probability tables on nodes (prior probability on source nodes, conditional probabilities on other nodes). Add enough error checking facilities to ensure valid input, e.g., probability distribution not adding up to one. Limits on the architecture: nodes 7-10, depth 3-5, arcs 7-15. Phase 1.1 submission on Canvas, source code of the graph object, well commented to understand the design. Optional: an one page design of the object.
1.2. (DUE: 4-5-2021-M-W-11:59pm) The graph object should be able to input these values and answer queries by computing over the probabilities from the tables on nodes. Inferencing algorithms are in Ch14.1-2, Russell-Norvig Text 3rd Ed. (Ch 13 for 4th ed). There are 3 algorithms, recursive, variable elimination or dynamic programming, and Stochastic. I suggest, you code the first algorithm. You must follow the book’s Enumeration-Ask algorithm, with possible “memoisation” if you know it. Using downloaded code is ok as long as it follows the book’s algorithm, but follow my guidelines as above, refer-modify-describe-own.
Phase 1.2 submission on Canvas, source code of the graph object (update, if you want, from the previous phase) plus the inferencing method, well commented to understand the design. Debug with the Burglary example computing P(j | m). Optional: Output the call tree as in Homework-2.
Phase 2 (April 25-Sun by 9pm, on canvas, code+ brief design/description of 3 KBs + 3x3 query answer screen shot): Design three separate knowledge bases as asked above, and answer minimum three queries on each of the 3 knowledge bases. Extend your last report with any change in the Bayesian Networks. Screen dump, with possible explanations.
The network may be abstract, and values may be hypothetical, although examples from real life would be nice to have! This is a real piece of AI.
