Attentive Perturbation: Extending Prefix Tuning to Large Language Models Inner Representations

From adapters to prefix-tuning, parameter efficient fine-tuning (PEFT) has been a well investigated research field in the past few years, which has led to an entire family of alternative approaches for large language model fine-tuning. All these…

Temporo-basal sulcal connections: a manual annotation protocol and an investigation of sexual dimorphism and heritability

The temporo-basal region of the human brain is composed of the collateral, the occipitotemporal, and the rhinal sulci. We manually rated (using a novel protocol) the connections between rhinal/collateral (RS-CS), collateral/occipito-temporal (CS-OTS…

Interpretable automatic detection of incomplete hippocampal inversions using anatomical criteria

Incomplete Hippocampal Inversion (IHI) is an atypical anatomical pattern of the hippocampus that has been associated with several brain disorders (epilepsy, schizophrenia). IHI can be visually detected on coronal T1 weighted MRI images. IHI can be…

Convergence rates and approximation results for SGD and its continuous-time counterpart

This paper proposes a thorough theoretical analysis of Stochastic Gradient Descent (SGD) with non-increasing step sizes. First, we show that the recursion defining SGD can be provably approximated by solutions of a time inhomogeneous Stochastic…

Quantum fluctuations induce collective multi-phonons in finite Fermi liquids

We show that collective multi-phonon states in atomic nuclei emerge at high excitation energies when quantum fluctuations are included beyond the independent particle approximation. The quadrupole response of a nucleus is studied using an extension…

Massively parallel computation of globally optimal shortest paths with curvature penalization

We address the computation of paths globally minimizing an energy involving their curvature, with given endpoints and tangents at these endpoints, according to models known as the Reeds-Shepp car (reversible or forward only), the Euler-Mumford…

Barycentric embeddings for geometric manifold learning

An MRI image has over 60,000 pixels. The largest known human protein consists of around 30,000 amino acids. We call such data high-dimensional. In practice, most high-dimensional data is high-dimensional only artificially. For example, of all the…
