چکیده

This paper focuses on building a spatio-temporal AI inference engine for estimating hard disk reliability. Most electronic systems such as disks routinely collect reliability parameters in the field to monitor health of system. Changes function time are monitored and any observed changes compared with known failure signatures. If trajectory measured data matches that signature, operators alerted take corrective action. However, interest lies being able identify failures before they occur. The state art methodology including our prior work is train machine learning models temporal sequence capturing variations across multiple features using it predict remaining useful life devices. we show this prediction capability alone not sufficient can lead low precision uncertainty around very large. primarily due non-uniform progression feature patterns over time. Our hypothesis accuracy be improved if combine methods spatial analysis compares value key SMART devices similar model fixed window (unlike method which uses from single device much larger historical window). In paper, first describe both approaches, select various hyperparameters, then workflow these two methodologies provide comparative results. results illustrate average long-short memory networks impending next ten days was 84 percent. To improve precision, use set identified potential start applying anomaly detection those disks. helps us remove false positives tighter bound failure.

Indirect inference for spatio-temporal autoregression models

In this note we introduce a new inferential method for STAR (spatio-temporal autoregression) models. Due to the complexity of such models the maximum likelihood estimation is difficult to undertake when several nearest neighbours are included in the model, see Ali (1979). Moreover, only approximate likelihoods are available in practice because of the observations lying on the edges of the spati...

STEPQ: Spatio-Temporal Engine for Complex Pattern Queries

With the increasing complexity and wide diversity of spatiotemporal applications, the query processing requirements over spatiotemporal data go beyond the traditional query types, e.g., range, kNN, and aggregation queries along with their variants. Most applications require support for evaluating powerful spatio-temporal pattern queries (STPQs) that form higher-order correlations and compositio...

Efficient Gaussian Process Inference for Short-Scale Spatio-Temporal Modeling

This paper presents an efficient Gaussian process inference scheme for modeling shortscale phenomena in spatio-temporal datasets. Our model uses a sum of separable, compactly supported covariance functions, which yields a full covariance matrix represented in terms of small sparse matrices operating either on the spatial or temporal domain. The proposed inference procedure is based on Gibbs sam...

Estimating likelihoods for spatio-temporal models using importance sampling

This paper describes how importance sampling can be applied to estimate likelihoods for spatiotemporal stochastic models of epidemics in plant populations, where observations consist of the set of diseased individuals at two or more distinct times. Likelihood computation is problematic because of the inherent lack of independence of the status of individuals in the population whenever disease t...

Spatio-Temporal Tensor Completion for Estimating Missing Internet Traffic Data

Network traffic data consists of Traffic Matrix (TM), which represents the volumes of traffic between Origin and Destination (OD) pairs in the network. It is a key input parameter of network engineering tasks. However, direct measurement of the OD pairs traffic is usually not feasible. Even good traffic measurement systems can suffer from errors, missing data. So obtaining the ODs traffic preci...
