  • [1204.4366] Multipath-​​dominant, pulsed doppler analy­sis of rotat­ing blades

    “We present a novel angu­lar fin­ger­print­ing algo­rithm for detect­ing changes in the direc­tion of rota­tion of a tar­get with a mono­sta­tic, sta­tion­ary sonar plat­form. Unlike other approaches, we assume that the target’s cen­troid is sta­tion­ary, and exploit doppler mul­ti­path sig­nals to resolve the oth­er­wise unavoid­able ambi­gu­i­ties that arise. Since the algo­rithm is based on an under­ly­ing dif­fer­en­tial topo­log­i­cal the­ory, it is highly robust to dis­tor­tions in the col­lected data. We demon­strate per­for­mance of this algo­rithm exper­i­men­tally, by exhibit­ing a pulsed doppler sonar col­lec­tion sys­tem that runs on a smart­phone. The per­for­mance of this sys­tem is suf­fi­ciently good to both detect changes in tar­get rota­tion direc­tion using angu­lar fin­ger­prints, and also to form high-​​resolution inverse syn­thetic aper­a­ture images of the target.”

  • [1204.3850] Sim­ple Agents Learn to Find Their Way: An Intro­duc­tion on Map­ping Polygons

    “This paper gives an intro­duc­tion to the prob­lem of map­ping sim­ple poly­gons with autonomous agents. We focus on min­i­mal­is­tic agents that move from ver­tex to ver­tex along straight lines inside a poly­gon, using their sen­sors to gather local obser­va­tions at each ver­tex. Our atten­tion revolves around the ques­tion whether a given con­fig­u­ra­tion of sen­sors and move­ment capa­bil­i­ties of the agents allows them to cap­ture enough data in order to draw con­clu­sions regard­ing the global lay­out of the poly­gon. In par­tic­u­lar, we study the prob­lem of recon­struct­ing the vis­i­bil­ity graph of a sim­ple poly­gon by an agent mov­ing either inside or on the bound­ary of the poly­gon. Our aim is to pro­vide insight about the algo­rith­mic chal­lenges faced by an agent try­ing to map a poly­gon. We present an overview of tech­niques for solv­ing this prob­lem with agents that are equipped with sim­ple sen­so­r­ial capa­bil­i­ties. We illus­trate these tech­niques on exam­ples with sen­sors that mea– sure angles between lines of sight or iden­tify the pre­vi­ous loca­tion. We give an overview over related prob­lems in com­bi­na­to­r­ial geom­e­try as well as graph exploration.”

  • [1204.4202] Fuzzy Dynam­i­cal Genetic Pro­gram­ming in XCSF

    “A num­ber of rep­re­sen­ta­tion schemes have been pre­sented for use within Learn­ing Clas­si­fier Sys­tems, rang­ing from binary encod­ings to Neural Net­works, and more recently Dynam­i­cal Genetic Pro­gram­ming (DGP). This paper presents results from an inves­ti­ga­tion into using a fuzzy DGP rep­re­sen­ta­tion within the XCSF Learn­ing Clas­si­fier Sys­tem. In par­tic­u­lar, asyn­chro­nous Fuzzy Logic Net­works are used to rep­re­sent the tra­di­tional condition-​​action pro­duc­tion sys­tem rules. It is shown pos­si­ble to use self-​​adaptive, open-​​ended evo­lu­tion to design an ensem­ble of such fuzzy dynam­i­cal sys­tems within XCSF to solve sev­eral well-​​known continuous-​​valued test problems.”

  • [1204.3293] Effi­ciently decod­ing strings from their shingles

    “Deter­min­ing whether an unordered col­lec­tion of over­lap­ping sub­strings (called shin­gles) can be uniquely decoded into a con­sis­tent string is a prob­lem that lies within the foun­da­tion of a broad assort­ment of dis­ci­plines rang­ing from net­work­ing and infor­ma­tion the­ory through cryp­tog­ra­phy and even genetic engi­neer­ing and lin­guis­tics. We present three per­spec­tives on this prob­lem: a graph the­o­retic frame­work due to Pevzner, an automata the­o­retic approach from our pre­vi­ous work, and a new insight that yields a time-​​optimal stream­ing algo­rithm for deter­min­ing whether a string of $n$ char­ac­ters over the alpha­bet $Sigma$ can be uniquely decoded from its two-​​character shin­gles. Our algo­rithm achieves an over­all time com­plex­ity $Theta(n)$ and space com­plex­ity $O(|Sigma|)$. As an appli­ca­tion, we demon­strate how this algo­rithm can be extended to larger shin­gles for effi­cient string reconciliation.”

  • What if Inter­ac­tiv­ity is the New Pas­siv­ity? Jonathan Sterne /​ McGill Uni­ver­sity | Flow

    “What if all the bad things that media crit­ics have been said about pas­siv­ity for the past cen­tury or two are now equally applic­a­ble to all the demands to inter­act, to par­tic­i­pate? What if inter­ac­tiv­ity is now one of the cen­tral hinges through which power works? In many moments today, the most com­pli­ant ges­ture we can make is to con­sent to inter­act on the terms pre­sented to us by our soft­ware and machines. This pull is espe­cially strong in those com­mer­cial plat­forms that cel­e­brate their own dif­fer­ence from the so-​​called pas­sive media of pre­vi­ous decades, and in the process mon­e­tize their users’ par­tic­i­pa­tion either directly or indi­rectly. What if—from time to time—we chose not to iden­tify with the inter­ac­tive promise of new media plat­forms or for that mat­ter new media art? What if, when the new media savants lam­bast so-​​called old media audi­ences as denizens of pas­siv­ity and ide­ol­ogy, we say, “yes, that’s me”?”

    “But I think it’s clear what his real objec­tion was: uni­ver­sal suf­frage has the poten­tial to advance social­is­tic causes, inter­fer­ing with his laissez-​​faire project. From his auto­bi­og­ra­phy: “Another exten­sion of the fran­chise since made…will inevitably be fol­lowed by a still more rapid growth of social­is­tic leg­is­la­tion.” When he real­ized women’s equal­ity could poten­tially inter­fere with laissez-​​faire eco­nom­ics, it was time for women’s equal­ity to get cut from his over­all the­ory of a bet­ter world.

  • BloJJ — About con­fer­ence poster design and defense:

    “My approach is dif­fer­ent. Poster pre­sen­ta­tion, like con­fer­ence pre­sen­ta­tion, belongs more to the area of dra­matic arts than to mar­ket­ing. It is information/​entertainment, and that is the main thing you have to bear in mind when prepar­ing for the ses­sion. Plus, while at a con­fer­ence you have the full atten­tion of your audi­ence (shared, of course, with email, Face­book, plus the 10% that are sim­ply speak­ing) in a poster ses­sion you have to first attract the atten­tion of the peo­ple wan­der­ing around a hall shared with other 20 to 100 posters, then keep them there for the dura­tion of the spiel and while you start a new one, and then, of course, con­vey the infor­ma­tion you want to share with your poster. ”

We shouldn’t worry so much about doing the wrong things righter, but we should be aware that that may be the case and always work to be doing the right things. In the end, show­ing improve­ment and build­ing momen­tum can lead to excit­ing changes. In fair­ness, it can also come crash­ing to the ground if the right kinds of changes aren’t made at some point, but this should not deter any­one who thinks some­thing can be made bet­ter from try­ing to do so and it cer­tainly should not be a rea­son to do nothing!”

  • Tanya Khovanova’s Math Blog » Blog Archive » Inter­lock­ing Polyominoes

    “A set of poly­omi­noes is inter­locked if no sub­set can be moved far away from the rest. It was known that poly­omi­noes that are built from four or fewer squares do not inter­lock. The project of Dhawan and his men­tor was to inves­ti­gate the inter­locked­ness of larger poly­omi­noes. And they totally deliv­ered. They quickly proved that you can inter­lock poly­omi­noes with eight or more squares. Then they proved that pen­tomi­noes can’t inter­lock. This left them with a gray area: what hap­pens with poly­omi­noes with six or seven squares? After draw­ing many beau­ti­ful pic­tures, they finally found the struc­ture pre­sented in our accom­pa­ny­ing image. The sys­tem con­sists of 12 hex­omi­noes and 5 pen­tomi­noes, and it is rigid. You can­not move a thing. That means that hex­omi­noes can be inter­locked and thus the gray area was resolved.”

The basic idea is that the pop­u­la­tion resides in a pool (imple­mented using CouchDB), with clients pulling indi­vid­u­als from the pool, doing stuff on them, and putting them back in the pool. The algo­rithm uses, as much as pos­si­ble, CouchDB fea­tures (such as revi­sions and views) to achieve good per­for­mance.

    “If the major pub­lish­ers switch to sell­ing ebooks with­out DRM, then they can enable cus­tomers to buy books from a vari­ety of out­lets and move away from the walled gar­den of the Kin­dle store.

  • How fast is bit packing?

    On my mac­book air (Intel core i7), I get that the unpack­ing speed is not very sen­si­tive to the spe­cific num­ber of bits: gen­er­ally, the smaller the bit width, the faster the unpack­ing. The pack­ing speed is much faster when the bit width is 8 or 16. Even so, the dif­fer­ence is only by a fac­tor of two or so. The results are pre­sented in the next fig­ure. On the y axis, you have the time (smaller is bet­ter). On the the x axis, we have the num­ber of bits we packed to. For exam­ple, when bit is 1, we pack 32 inte­gers into a sin­gle 32-​​bit word. When the num­ber of bits is set to 32 bits, we have a reg­u­lar copy.
