A novel t.chnique is proposed t. improve t.e performance of voice act.vit. det.ct.on(VAD) by using deep belief net.orks(DBN) wit. a likelihood rat.o(LR). t.e likelihood rat.o is derived from t.e speech and noise spect.al component. t.at.are assumed t. follow t.e Gaussian probabilit. densit. funct.on(PDF). t.e proposed algorit.m employs DBN learning in order t. classify voice act.vit. by using t.e input.signal t. calculat. t.e likelihood rat.o. Experiment. show t.at.t.e proposed algorit.m yields improved result. in various noise environment., compared t. t.e convent.onal VAD algorit.ms. Furt.ermore, t.e DBN based algorit.m decreases t.e det.ct.on probabilit. of error wit. [0.7, 2.6] compared t. t.e support.vect.r machine based algorit.m.

As locat.on dat. are widely available t. port.ble devices, t.aject.ry t.acking of moving object. has become an essent.al t.chnology for most.locat.on-based services. t. maint.in such st.eaming dat. of locat.on updat.s from mobile client., convent.onal approaches such as t.me-based regular locat.on updat.ng and dist.nce-based locat.on updat.ng have been used. However, t.ese met.ods suffer from t.e large amount.of dat., redundant.locat.on updat.s, and large t.aject.ry est.mat.on errors due t. t.e varying speed of moving object.. In t.is paper, we propose a simple but.efficient.online t.aject.ry dat. reduct.on met.od for port.ble devices. t. solve t.e problems of redundancy and large est.mat.on errors, t.e proposed algorit.m comput.s t.aject.ry errors and finds a recent.locat.on updat. t.at.should be sent.t. t.e server t. sat.sfy t.e user requirement.. We evaluat. t.e proposed algorit.m wit. real GPS t.aject.ry dat. consist.ng of 17 201 t.aject.ries. t.e int.nsive simulat.on result. prove t.at.t.e proposed algorit.m always meet. t.e given user requirement. and exhibit. a dat. reduct.on rat.o of great.r t.an 87% when t.e accept.ble t.aject.ry error is great.r t.an or equal t. 10 met.rs.
