Graph Chatbot

Chattez avec Graph Search

Posez n’importe quelle question sur les cours, conférences, exercices, recherches, actualités, etc. de l’EPFL ou essayez les exemples de questions ci-dessous.

AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.

Epigenetic Priming of Memory Updating during Reconsolidation to Attenuate Remote Fear Memories

Johannes Gräff

Traumatic events generate some of the most enduring forms of memories. Despite the elevated lifetime prevalence of anxiety disorders, effective strategies to attenuate long-term traumatic memories are scarce. The most efficacious treatments to diminish rec ...

A Primer on Hardware Prefetching

Babak Falsafi

Since the 1970’s, microprocessor-based digital platforms have been riding Moore’s law, allowing for doubling of density for the same area roughly every two years. However, whereas microprocessor fabrication has focused on increasing instruction execution r ...

Dynamic brain networks explored by structure-revealing methods

Nora Leonardi

The human brain is a complex system able to continuously adapt. How and where brain activity is modulated by behavior can be studied with functional magnetic resonance imaging (fMRI), a non-invasive neuroimaging technique with excellent spatial resolution ...

High Sum-Rate Three-Write and Nonbinary WOM Codes

Write-once memory (WOM) is a storage medium with memory elements, called cells, which can take on q levels. Each cell is initially in level 0 and can only increase its level. A t-write WOM code is a coding scheme, which allows one to store t messages to th ...

Multisensory Integration in Complete Unawareness:Evidence From Audiovisual Congruency Priming

Nathan Quentin Faivre

Multisensory integration is thought to require conscious perception. Although previous studies have shown that an invisible stimulus could be integrated with an audible one, none have demonstrated integration of two subliminal stimuli of different modaliti ...

Noise-enhanced associative memories

Mohammad Amin Shokrollahi, Amin Karbasi, Amir Hesam Salavati

Recent advances in associative memory design through structured pattern sets and graph-based inference algorithms have allowed reliable learning and recall of an exponential number of patterns. Although these designs correct external errors in recall, they ...

Automatic Synthesis of Out-of-Core Algorithms

Viktor Kuncak, Christoph Koch, Ioannis Klonatos, Andres Nötzli, Andrej Spielmann

We present a system for the automatic synthesis of efficient algorithms specialized for a particular memory hierarchy and a set of storage devices. The developer provides two independent inputs: 1) an algorithm that ignores memory hierarchy and external st ...

Stress and cognition

Maria del Carmen Sandi Perez

Stress can affect cognition in many ways, with the outcome (i.e., facilitating or impairing) depending on a combination of factors related to both stress and the cognitive function under study. Among the factors identified as particularly relevant to defin ...

Coupled neural associative memories

Mohammad Amin Shokrollahi, Amin Karbasi, Amir Hesam Salavati

We propose a novel architecture to design a neural associative memory that is capable of learning a large number of patterns and recalling them later in presence of noise. It is based on dividing the neurons into local clusters and parallel plains, an arch ...

Lithium rescues synaptic plasticity and memory in Down syndrome mice

Diego Ghezzi

Down syndrome (DS) patients exhibit abnormalities of hippocampal-dependent explicit memory, a feature that is replicated in relevant mouse models of the disease. Adult hippocampal neurogenesis, which is impaired in DS and other neuropsychiatric diseases, p ...
