Foundation

Pure C Transformer Engine & 3.45M Baseline

SOURCE-VERIFIED

Constructed the pure C autoregressive Transformer baseline (3.45M parameters) with pre-allocated buffer activation inspection and an interactive terminal REPL.

TinyCoherent
Scaling

23M Parameter Scaling Experiment

AUTHOR-REPORTED

Scaled model parameter capacity from 3.45M to 23M in C; training throughput and stability observations reported in founder research log.

TinyCoherent
Tokenization

Character Bottleneck Identification & Subword BPE Transition

AUTHOR-REPORTED

Identified character-level sequence length inflation; implemented C subword BPE tokenizer with author-reported ~3.8x sequence compression over sample text.

TinyCoherent
Instruction Tuning

Pure C Conversational Fine-Tuning with Prompt-Loss Masking

AUTHOR-REPORTED

Implemented prompt-loss masking in pure C autograd, zeroing backpropagation gradients across prompt tokens to isolate assistant response loss.

Reasoning

Rung 6 V2: Discarding 1.5M Tokens for High-Integrity Scratchpads

AUTHOR-REPORTED

Discarded 1.5M synthetic tokens containing logical drift; curated step-by-step scratchpad dataset to evaluate reasoning consistency.

TinyCoherent
Runtime

Apple Silicon BLAS/Accelerate Training Runtime Optimization

DESIGN CLAIM / HYPOTHESIS

Integrated Apple Accelerate BLAS (cblas_sgemm) and zero-allocation inner loops on Apple Silicon; compute bandwidth bounds reported in research log.

TinyCoherent
Initial Hypothesis

Norepinephrine Dynamic Infusion Modeling

HYPOTHESIS

Formulated the mathematical simulation framework linking continuous norepinephrine infusion rates to acute hemodynamic response curves.

Physiological Modeling Research
Pharmacodynamics

Concentration-to-Blood-Pressure Response Modeling

MEASURED

Modeled receptor-level pharmacodynamic curves translating drug plasma concentration into systemic vascular resistance and arterial pressure trajectories.

Physiological Modeling Research
Clinical Variance

Individual Patient Response Prediction Challenges

OBSERVED

Encountered significant clinical forecasting failure when attempting to generalize predictions across distinct patients due to unmodeled autonomic tone variance.

Physiological Modeling Research
Null Finding

Physiological Data Expansion Null Result Trial

FAILED / NULL

Adding additional physiological channels failed to yield clinically meaningful MAP predictive improvements (+0.0078 mmHg, 95% CI crosses zero), though heart rate exposed compensatory baroreflex feedback.

Physiological Modeling Research
Foundational Vision

Executable Biological Hypotheses Architecture

DESIGN CLAIM / HYPOTHESIS

Formulated the initial architectural proposal for transforming theoretical biological hypotheses into executable, computationally verifiable pipelines.

Virtual Lab
Scientific Worlds

Multi-Agent Executable Scientific World Modeling

DESIGN CLAIM / HYPOTHESIS

Outlined conceptual models for multi-agent simulation environments where models, instruments, and hypotheses interact within a state-managed scientific world.

Virtual Lab
Epistemology & Instrumentation

Direct Model-to-Physical Experimentation Coupling

DESIGN CLAIM / HYPOTHESIS
