The faithful copy neuron

Lawrence Sirovich
2012 Journal of Computational Neuroscience  
This results in an unusual mechanism for neuronal firing that uses background noise to achieve the desired firing rate.  ...  This optimal performance is likely accomplished by use of local circuitry that adjusts conductances to match input currents so that the neuron operates near the threshold for firing.  ...  I also thank Ellen Paley for her careful help in the preparation of this paper and for her great patience with the many drafts that preceded this one.  ...

Constructive neural-network learning algorithms for pattern classification

R. Parekh, J. Yang, V. Honavar
2000 IEEE Transactions on Neural Networks  
Additionally, we show how the incorporation of a local pruning step can eliminate several redundant neurons from MTiling-real networks.  ...  We prove the convergence of these algorithms and empirically demonstrate their applicability to practical pattern classification problems.  ...  The input layer neurons are designed to allow the patterns to be input to the network and thus simply copy their input to their output. III.  ...

DNA Homeostasis and Senescence: Lessons from the Naked Mole Rat

Harvey Boughey, Mateusz Jurga, Sherif F. El-Khamisy
2021 International Journal of Molecular Sciences  
Therefore, limiting the accumulation of DNA damage is essential for healthy neuronal populations.  ...  The build-up of senescent cells negatively affects the local cellular micro-environment and drives ageing associated disease, including neurodegeneration.  ...  The NMR's exceptional neuronal preservation is the culmination of various mechanisms, namely improved antioxidant response, higher fidelity translation, stringent DNA repair, faithful proteome function  ...

Early Intervention with High‐Dose Acyclovir Treatment during Primary Herpes Simplex Virus Infection Reduces Latency and Subsequent Reactivation in the Nervous System In Vivo

N. M. Sawtell, R. L. Thompson, L. R. Stanberry, D. I. Bernstein
2001 Journal of Infectious Diseases  
During primary infection, herpes simplex virus (HSV) enters the nervous system where the viral genome can be maintained in a state of transcriptional repression, or "latency," in neuronal nuclei (reviewed  ...  Treatment with 50 mg/kg of acyclovir every 8 h reduced the number of latently infected neurons by 190% when treatment was begun before 24 h after infection and by 80% and 70% when begun at 48 or 72 h after  ...  In contrast, surface replication was not a faithful indicator of the level of establishment of latency. However, this parameter did appear to correlate with the copy number profile.  ...

Does Aneuploidy in the Brain Play a Role in Neurodegenerative Disease? [chapter]

Hilda van den Bos, Diana C.J. Spierings, Floris Foijer, Peter M. Lansdorp
2017 Chromosomal Abnormalities - A Hallmark Manifestation of Genomic Instability  
In addition to these well-known roles of aneuploidy, chromosome copy number changes have also been reported in some studies to occur in neurons in healthy human brain and possibly even more in Alzheimer's  ...  We discuss possible mechanisms for the origin of aneuploidy and the pros and cons of different techniques used to study aneuploidy in the brain, and we provide a future perspective.  ...  Since neurons are postmitotic, methods requiring dividing cells to determine chromosome copy numbers cannot be used when studying aneuploidy in neurons.  ...

A Neural System for Faithful Color Reproduction in Industrial Printing Processes

Beatrice Lazzerini, Francesco Pistolesi
2018 2018 International Joint Conference on Neural Networks (IJCNN)  
The system considers a master color, then compares it to a copy, and returns an objective degree of color fidelity of the copy to the master.  ...  The strengths of the system are that it can measure the difference of colors in a way that is incredibly close to that perceived by the human eye, and the fact that it can do that canceling the color distortion  ...  ACKNOWKEDGMENT The authors would like to thank Roberto Ciardi, Alessandro Degiovanni and Giovanni Falzone for developing the system.  ...

Towards Faithful Model Explanation in NLP: A Survey [article]

Qing Lyu, Marianna Apidianaki, Chris Callison-Burch
2022 arXiv   pre-print
An essential principle of model explanation is Faithfulness, i.e., an explanation should accurately represent the reasoning process behind the model's prediction.  ...  This survey first discusses the definition and evaluation of Faithfulness, as well as its significance for explainability.  ...  Therefore, SmoothGrad proposes to create a few noisy copies of the original input, compute relevance maps for each copy with any existing method, and finally average all maps to obtain a less noisy map  ...
