A Unified View of Algorithms for Path Planning Using Probabilistic Inference on Factor Graphs

no code implementations19 Jun 2021 Francesco A. N. Palmieri, Krishna R. Pattipati, Giovanni Di Gennaro, Giovanni Fioretti, Francesco Verolla, Amedeo Buonanno

Even if path planning can be solved using standard techniques from dynamic programming and control, the problem can also be approached using probabilistic inference.

Path Planning Using Probability Tensor Flows

no code implementations5 Mar 2020 Francesco A. N. Palmieri, Krishna R. Pattipati, Giovanni Fioretti, Giovanni Di Gennaro, Amedeo Buonanno

In this paper, probability propagation is applied to model agent's motion in potentially complex scenarios that include goals and obstacles.

Intent Classification in Question-Answering Using LSTM Architectures

1 code implementation25 Jan 2020 Giovanni Di Gennaro, Amedeo Buonanno, Antonio Di Girolamo, Armando Ospedale, Francesco A. N. Palmieri

Question-answering (QA) is certainly the best known and probably also one of the most complex problem within Natural Language Processing (NLP) and artificial intelligence (AI).

An Analysis of Word2Vec for the Italian Language

no code implementations25 Jan 2020 Giovanni Di Gennaro, Amedeo Buonanno, Antonio Di Girolamo, Armando Ospedale, Francesco A. N. Palmieri, Gianfranco Fedele

Word representation is fundamental in NLP tasks, because it is precisely from the coding of semantic closeness between words that it is possible to think of teaching a machine to understand text.

Optimized Realization of Bayesian Networks in Reduced Normal Form using Latent Variable Model

1 code implementation18 Jan 2019 Giovanni Di Gennaro, Amedeo Buonanno, Francesco A. N. Palmieri

Bayesian networks in their Factor Graph Reduced Normal Form (FGrn) are a powerful paradigm for implementing inference graphs.

3-D Hand Pose Estimation from Kinect's Point Cloud Using Appearance Matching

no code implementations7 Apr 2016 Pasquale Coscia, Francesco A. N. Palmieri, Francesco Castaldo, Alberto Cavallo

We present a novel appearance-based approach for pose estimation of a human hand using the point clouds provided by the low-cost Microsoft Kinect sensor.

Discrete Independent Component Analysis (DICA) with Belief Propagation

no code implementations26 May 2015 Francesco A. N. Palmieri, Amedeo Buonanno

We apply belief propagation to a Bayesian bipartite graph composed of discrete independent hidden variables and discrete visible variables.

Towards Building Deep Networks with Bayesian Factor Graphs

no code implementations16 Feb 2015 Amedeo Buonanno, Francesco A. N. Palmieri

We propose a Multi-Layer Network based on the Bayesian framework of the Factor Graphs in Reduced Normal Form (FGrn) applied to a two-dimensional lattice.

A Comparison of Algorithms for Learning Hidden Variables in Normal Graphs

no code implementations26 Aug 2013 Francesco A. N. Palmieri

A Bayesian factor graph reduced to normal form consists in the interconnection of diverter units (or equal constraint units) and Single-Input/Single-Output (SISO) blocks.
