    [R] Breakthrough Neuron-Mimicking Nanoscale Electronic Circuit Element for Neuromorphic AI

    Posted: 07 Oct 2020 03:25 PM PDT

    In a paper recently published in Nature, researchers Suhas Kumar of Hewlett Packard Laboratories, R. Stanley Williams with Texas A&M University, and the late Stanford PhD student Ziwen Wang introduce an isolated nanoscale electronic circuit element that can perform nonmonotonic operations and transistorless all-analogue computations. With input voltages, it can output not just simple spikes but a whole array of neural activity such as bursts of spikes, self-sustained oscillations, and other brain activities.

    Free October 14 Talk with Moshe Vardi on Lessons from COVID-19: Efficiency vs. Resilience

    Posted: 07 Oct 2020 01:16 PM PDT

    October 14, join Moshe Y. Vardi Professor of Computer Science and Director of the Ken Kennedy Institute for Information Technology at Rice University, for the free ACM TechTalk, "Lessons from COVID-19: Efficiency vs Resilience."

    In both computer science and economics, efficiency is a cherished property. In computer science, the field of algorithms is almost solely focused on their efficiency. In economics, the main advantage of the free market is that it promises "economic efficiency." A major lesson from COVID-19 is that both fields have over-emphasized efficiency and under-emphasized resilience. In this talk, Prof. Vardi argues that resilience is a more important property than efficiency and discusses how the two fields can broaden their focus to make resilience a primary consideration

    What numbers can fractional binary notation represent?

    Posted: 07 Oct 2020 07:17 AM PDT

    In Computer Systems: a Programmer's Perspective:

    Consider a notation of the form $bm b{m - 1} \dots b1 b_0 . b{-1} b{-2} \dots b{-n + 1} b{- n}$, where each binary digit, or bit, $b_i$ ranges between 0 and 1. This notation represents a number $b$ defined as $$b = \summ{i =- n} 2i × b_i$$

    Assuming we consider only finite-length encodings, fractional binary notation can only represent numbers that can be written $x \times 2y$ . Other values can only be approximated.

    Isn't it that fractional binary notation can only represent numbers that can be written $\summ_{i =- n} 2i × b_i$? Why is it $x \times 2y$?

    Thanks.

    Is the exponent value in floating point number encoded by ones' complement method?

    Posted: 07 Oct 2020 10:02 AM PDT

    From Computer Systems: a Programmer's Perspective:

    The bit representation of a floating-point number is divided into three fields to encode these values: the single sign bit s, the k-bit exponent field exp, and the n-bit fraction field frac.

    Case 1: Normalized Values

    when the bit pattern of exp is neither all zeros (numeric value 0) nor all ones (numeric value 255 for single precision, 2047 for double), the exponent field is interpreted as representing a signed integer in biased form. That is, the exponent value is $E = e − Bias$, where $e$ is the unsigned number having bit representation $e_{k − 1} \dots e_1 e_0$ and $Bias$ is a bias value equal to $2{k − 1} − 1$ (127 for single precision and 1023 for double). This yields exponent ranges from −126 to +127 for single precision and −1022 to +1023 for double precision.

    In Case 1 Normalized Values, is the exponent value a signed integer and encoded by ones' complement method? Thanks.
