thesis

BGU MSc thesis on the ROLL method (Rate Optimized Likelihood Loss). See impl for the implementation project this thesis documents.

main.tex — root document; defines all title/author/supervisor commands, includes all chapters
Main_pages/ — cover_page, title_page, abstract, acknowledgements, abstract_heb, cover_heb
content/<chapter>/ — one folder per chapter with its own .tex file
content/images/ — shared image path (set via \graphicspath)
bibliography/thesis.bib — references
bibliography/unsrtnat_adjusted_for_bgu_thesis.bst — custom BGU bibliography style (do not edit)

Thesis metadata (title, author, supervisor, month, year) defined as commands at top of main.tex
Hebrew title/author/supervisor have he suffix commands (\thesistitlehe, etc.)
Both English and Hebrew ToC, abstract, and cover pages are required by BGU
Chapters added via \input{content/<chapter>/<chapter>} with a matching \addtocontents{tocheb} line
Build engine: pdflatex (uses \usepackage[utf8x]{inputenc}, not xelatex)
Math notation: data points are bold (\mathbf{x}_i); batches are \mathcal{B}_0 / \mathcal{B}_1
KDE background (general technique) in Ch. 2 (sec:kde-background); Ch. 3 back-references it; Ch. 2 ends with forward pointer to sec:roll-kde
sec:imbalanced-tpr-fpr and sec:neyman-pearson live in Ch. 2; Ch. 3 sec:problem-formulation \Cref's them — do not rename

See subnodes for per-chapter guidelines and section details.

Ch.	Title	File	Target
1	Introduction	`content/introduction/introduction.tex`	4–6 pp
2	Background / Related Work	`content/related_work/related_work.tex`	15–20 pp
3	Method	`content/method/method.tex`	~30 pp
4	Experiments	`content/experiments/experiments.tex`	15–20 pp
5–6	Discussion + Conclusion	`content/discussion_and_conclusions/`	8–12 pp

Template uses utf8x inputenc, which requires the ucs nix/texlive package
Hebrew rendering via babel-hebrew (pdflatex approach, not fontspec/xelatex)
Example images in content/related_work/images/ are from the template — safe to delete
flake.nix uses rec on the derivation so buildInputs is in scope for PATH export
nix develop devShell includes python3+sympy — use it to verify math claims, never check mentally
KDE backward pass uses inverse-function-theorem approach deliberately (user must explain it verbally)
Correct gradient of threshold w.r.t. negative-class score: σ'(τ−x_i) / Σ_j σ'(τ−x_j) — sympy-verified
(NIX BUILD) New .tex files must be git add'ed before nix build. Nix flakes use git to enumerate source files; untracked files are invisible to the build. Symptom: silent LaTeX failure — TOC, LoF, and LoT all appear empty in the output PDF. Fix: git add <new-file>, then rebuild.

flake.nix — Nix build; nix build produces result/main.pdf; nix develop for dev shell
flake.lock — pinned to nixpkgs-unstable as of 2026-06-16
main.tex — fill in \thesistitle, \thesisauthorname, \thesissupervisername, \thesismonth, \thesisyear

thesis/introduction — Ch. 1 guidelines: structure, length, what to include
thesis/related-work — Ch. 2 section structure, placement markers, label conventions
thesis/method — Ch. 3 section status table, derivation gotchas
thesis/experiments — Ch. 4 guidelines: datasets, baselines, metrics
thesis/discussion — Ch. 5–6 guidelines: failure modes, future work
thesis/todos — project TODOs
