Position (1,1) with region [[6,7],[0,1]] and kernel [[1,0],[0,1]]
correctly computes to 6×1 + 7×0 + 0×0 + 1×1 = 7, not 8.

diverse institutional contexts" since validation is planned future work
- Replace MNIST/ImageNet full dataset calculation with the actual Module 1 exercise
- New text: "Students calculate memory footprints, discovering that a single batch of 32 ImageNet images requires 19 MB, while the full dataset exceeds 670 GB."
- Aligns paper claims with the codebase (01_tensor.py Q1)
- Rephrase 'optimization opportunities' sentence to avoid dangling word
- Adjust 'roles industry desperately needs' to 'roles that the industry desperately needs'
- Change 'over dense layers' to 'compared to dense layers' to improve line break
- Reorder 'construct mental models gradually' to 'gradually construct mental models'
- Change 'self-paced professional development' to 'independent professional development'
- Align '09 CNNs' (Spatial) with the top Foundation row (01 Tensor)
- Align '15 Quant' and '16 Compress' with the top Foundation row
- Position '10-13' (Language path) and '17-18' (Accel/Memo) on the bottom row
- Center '14 Profiling' and '19 Benchmark' vertically between the two rows
- Remove 'Vision' and 'Language' labels
- Adjust tier labels to be consistently positioned above the top row
- Define a common LabelLine coordinate relative to the top of Foundation Row 1 (T.north + 1.2cm)
- Ensure all tier labels (FOUNDATION, ARCHITECTURE, OPTIMIZATION) are placed on this line
- Prevents labels from overlapping with nodes or being placed too low
- Maintains horizontal centering for each section
- Place all tier labels (FOUNDATION, ARCHITECTURE, OPTIMIZATION) on the same vertical line
- Center each label horizontally over its respective section using coordinate calculations
- Use Architecture label position as the anchor for height alignment
- Move Vision path definition after Language path to allow relative positioning
- Center '09 CNNs' node horizontally above the Language path (Tok-Trans)
- Update arrow routing to accommodate the new centered position
- Reroute the arrow from 04 Losses to 05 DataLoad to go between the rows
- Prevents the arrow from cutting through 06, 07, 08 nodes
- Improves visual clarity of the two-row layout
- Split Foundation modules (01-08) into two rows of 4 nodes each
- Row 1: 01 Tensor -> 04 Losses
- Row 2: 05 DataLoad -> 08 Training
- Connect end of Row 1 to start of Row 2 with a wrapped arrow
- Center 'FOUNDATION' label over the new two-row layout
- Reposition Profiling node to avoid overlap with Architecture branch
- Center Architecture label and align with Optimization label
- Increase font size of path labels for better readability
- Fix overlap of 'Speed' label with 'Transform' node
- Add single node focus framing throughout paper

- Switch to lining numbers for technical content
- Add widow/orphan penalties to reduce dangling lines
- Fix single-item bullet list (Intentional Gap section)
- Update author limit to 50 before et al truncation
- Fix tinytorch package references to match actual implementation
Trim detailed phase-by-phase validation plan to a concise summary.
Removes specific dates, sample sizes, and instrument names that would
age poorly. Keeps the Open Science Commitment and general validation
approach. Also removes two orphaned references (paas1992training,
sorva2012visual) that were only cited in the removed text.
The paper now uses biblatex for bibliography management, which requires
biber as the backend processor instead of bibtex. Updated both
compile_paper.sh and Makefile to use biber.
- Switch from natbib to biblatex for better author truncation control
- Fix package structure references (tinytorch.nn.conv → tinytorch.core.spatial)
- Fix import examples to use actual tinytorch API patterns
- Fix class references (Transformer → GPT, Attention → MultiHeadAttention)
- Correct Adam coefficient from 0.001 to 0.01
- Fix 11 bibliography entries with wrong/corrupted data:
- abelson1996sicp, bruner1960process, hotz2023tinygrad
- tanenbaum1987minix, perkins1992transfer, papert1980mindstorms
- vygotsky1978mind, blank2019nbgrader, roberthalf2024talent
- keller2025ai, pytorch04release, tensorflow20
- Fix organization author names using double braces
