Geometric Reliability of Neural Population Codes: Sampling Calibration and Within-Session Nonstationarity
Prashant C. Raju
Trial-to-trial variability limits how reliably neural population geometry can be estimated, while comparisons across populations depend on neuron and trial counts, response quality…
Geometric Phase Transition Enables Extreme Hippocampal Memory Capacity
Prashant C. Raju
Memory systems can store vastly different amounts of information despite similar hardware constraints. Here, we show that superior spatial memory emerges from a discrete stiffening…
The Geometric Canary: Predicting Steerability and Detecting Drift via Representational Stability
Prashant C. Raju
Reliable deployment of language models requires two capabilities that appear distinct but share a common geometric foundation: predicting whether a model will accept targeted behav…
From Syntax to Semantics: Geometric Stability as the Missing Axis of Perturbation Biology
Prashant C. Raju
The capacity to precisely edit genomes has outpaced our ability to predict the consequences. A cell can be genetically perfect and therapeutically useless: edited exactly as intend…
The Geometric Alignment Tax: Tokenization vs. Continuous Geometry in Scientific Foundation Models
Prashant C. Raju
Foundation models for biology and physics optimize predictive accuracy, but their internal representations systematically fail to preserve the continuous geometry of the systems th…
Directional coherence and effect magnitude in single-cell CRISPR perturbation responses
Prashant C. Raju
Single-cell CRISPR screens summarize each perturbation by how far cells move from their unperturbed state, averaging over cell-to-cell variation. Whether the cells moved together i…
Geometric Stability: The Missing Axis of Representations
Prashant C. Raju
Representational similarity methods compare the geometries of neural representations, but they do not measure how consistently the geometry of a single representation is recovered…
Controversial stimuli: pitting neural networks against each other as models of human recognition
Tal Golan, Prashant C. Raju, Nikolaus Kriegeskorte
Distinct scientific theories can make similar predictions. To adjudicate between theories, we must design experiments for which the theories make distinct predictions. Here we cons…
A Theory on Formatting Sensory Input for Cognition
Prashant C. Raju
Over the last few decades, a lot of progress has been made in understanding different aspects of the brain's ability to form abstract representations, but a specific mechanism for…
