The Age of Spiritual Machines: When Computers Exceed Human Intelligence

Submit yr notice: First released in 1998
------------------------

Ray Kurzweil is the inventor of the main leading edge and compelling expertise of our period, a world authority on synthetic intelligence, and certainly one of our best dwelling visionaries.

Now he bargains a framework for envisioning the twenty-first century—an age within which the wedding of human sensitivity and synthetic intelligence essentially alters and improves the best way we are living. Kurzweil's prophetic blueprint for the longer term takes us throughout the advances that inexorably bring about pcs exceeding the reminiscence means and computational skill of the human mind through the yr 2020 (with human-level services no longer a ways behind); in relationships with automatic personalities who should be our academics, partners, and fanatics; and in info fed directly into our brains alongside direct neural pathways.

Optimistic and difficult, thought-provoking and interesting, The Age of non secular Machines is the final word advisor on our highway into the subsequent century.

The Elements of User Experience: User-Centered Design for the Web and Beyond (2nd Edition) (Voices That Matter)

From the instant it used to be released virtually ten years in the past, components of consumer event turned a necessary reference for net and interplay designers internationally, and has come to outline the center ideas of the perform. Now, during this up-to-date, increased, and full-color new version, Jesse James Garrett has subtle his pondering the net, going past the computing device to incorporate details that still applies to the surprising proliferation of cellular units and functions.

Digital Mantras: The Languages of Abstract and Virtual Worlds

This paintings synthesizes rules from a couple of diverse disciplines to reach at a philosophy of creativity for the electronic age. Drawing principles from song, computing, artwork and philosophy, it explores the mixing of desktops into the artistic method. It exhibits how pcs might switch the best way we create.

A Survey of Characteristic Engine Features for Technology-Sustained Pervasive Games (SpringerBriefs in Computer Science)

This ebook scrutinizes pervasive video games from a technological point of view, concentrating on the sub-domain of video games that fulfill the factors that they utilize digital online game components. within the laptop video game undefined, using a video game engine to construct video games is usual, yet present video game engines don't aid pervasive video games.

In Fig. 7, only the first 24 filters, which cover the frequency range of [0, 4000] Hz, are shown. As illustrated in the figure, in the HFCC scheme, the overlapping among the filters is different from the traditional – and one filter can overlap not only with its closest neighbors but also with more remote neighbors. The most significant difference in the HFCC, when compared to the earlier MFCC schemes, is that the filter bandwidth is decoupled from the filter spacing. 36 Contemporary Methods for Speech Parameterization Fig.

This speech parameterization technique takes advantage of the latest advances in psychoacoustics known at that time and incorporates three engineering approximations of the properties of human hearing, among which are: (i) the critical-band spectral resolution, (ii) the equal-loudness curve, and (iii) the intensity-loudness power law. In the following, we outline the PLP speech parameterizations, following closely the exposition in Hermansky (1990). edu/~markskow/ 40 Contemporary Methods for Speech Parameterization Let us denote with n the discrete-time index, and with xðnÞ, n ¼ 0; 1; :::; N À 1 a discrete-time speech signal with length of N samples that has been sampled with sampling frequency fs .

In brief, let us denote with n the discrete-time index, and with xðnÞ a discrete-time speech signal that has been sampled with sampling frequency fs . Let us consider that the signal xðnÞ has been pre-processed as explained in Sect. 2 and has been segmented in frames with length of N samples. Each speech segment obtained to this end, represented by sðnÞ, n ¼ 0; 1; :::; N À 1, which was pre-emphasized and weighted by the Hamming window, is subject to the DFT,  Àj2pnk SðkÞ ¼ sðnÞ Á exp ; N n¼0 N À1 X  k ¼ 0; 1; :::; N À 1; where k is the index of the Fourier coefficients, SðkÞ.
