CRF-Matching: Conditional Random Fields for Feature-Based Scan Matching

open access: yesRobotics: Science and Systems III, 2007
Matching laser range scans observed at different points in time is a crucial component of many robotics tasks, including mobile robot localization and mapping. While existing techniques such as the Iterative Closest Point (ICP) algorithm perform well under many circumstances, they often fail when the initial estimate of the offset between scans is ...

Design of a Structured Parsing Model for Corporate Bidding Documents Based on Bi-LSTM and Conditional Random Field (CRF)

open access: yesInternational Journal of Information Technologies and Systems Approach, 2023
International projects are often realized through the bidding process, but the existence of information exchange barriers in different countries leads to a complex and tedious bidding process. In this paper, the authors study the complex problem of reading bidding documents, combine the artificial intelligence to analyze them in a structured way, and ...

Conditional random field-based mesh saliency

open access: yes, 2014
We propose a new method for detecting mesh saliency, a reflection of perception-based regional importance for 3D meshes. The basic idea is to incorporate the Conditional Random Field (CRF) framework with a saliency detection process.

A Conditional Random Field for Multiple-Instance Learning [PDF]

open access: yes, 2010
We present MI-CRF, a conditional random field (CRF) model for multiple instance learning (MIL). MI-CRF models bags as nodes in a CRF with instances as their states. It combines discriminative unary instance classifiers and pairwise dissimilarity measures.

Automatic Keyword Extraction from Documents Using Conditional Random Fields [PDF]

open access: yes, 2008
Keywords are subset of words or phrases from a document that can describe the meaning of the document. Many text mining applications can take advantage from it. Unfortunately, a large portion of documents still do not have keywords assigned. On the other
