GALLOP GlobAL Feature Fused LOcation Prediction for Different Check-in Scenarios using dotnet

ABSTRACT

Location prediction is widely used to forecast users’ next place to visit based on his/her mobility logs. It is an essential problem in location data processing, invaluable for surveillance, business, and personal applications. It is very challenging due to the sparsity issues of check-in data. An often ignored problem in recent studies is the variety across different check-in scenarios, which is becoming more urgent due to the increasing availability of more location check-in  pplications. we propose a new feature fusion based prediction approach, GALLOP, i.e., GlobAL feature fused LOcation Prediction for different check-in scenarios. Based on the carefully designed feature extraction methods, we utilize a novel combined prediction framework. Specifically, we set out to utilize the density estimation model to profile geographical features, i.e., context information, the factorization method to extract collaborative information, and a graph structure to extract location transition patterns of users’ temporal check-in sequence, i.e., content information.

EXISTING SYSTEM

We propose a new feature fusion approach, i.e., GlobAL feature fusion for LOcation Prediction (GALLOP), to cope with the variety problem in location prediction.
To improve the applicability of location prediction approach, We utilize several kinds of features and discuss their different characteristics in the variety of check-in scenarios. 
Three classes of features are used in GALLOP: context feature(geographical aspects), collaboration feature(users’ latent interest space) and content feature(places’ description attributes). We introduce intuitive ways to model these check-in features and then formalize a combination framework to deliver the predicted target places to end users.

DISADVANTAGES

In contrast, spatial feature based methods use the gravity and locality closeness measurements to fit into the location setting, but are usually difficult to generalize the temporal and other related features.
Though some recent work pay attention to these check-in behavior differences, the inherent variety between this check-ins and their affect to location prediction is usually missing
That existing predication methods cannot be directly applied to all check-in scenarios, where their performance vary greatly
PROPOSED SYSTEM

We design a multiple granularity model to profile the geographical closeness. We select the predicted candidates based on the combination of local district, local city and state scales. The weights of each scale are learned from training data.

Prove that the general location prediction approach is a better choice to tackle the location prediction challenges
