MACHINE LEARNING FOR SATELLITE-GUIDED WATER QUALITY MONITORINGVisionGEOMATIQUE2014
The document discusses using machine learning techniques for satellite-guided water quality monitoring. It covers using machine learning algorithms to automatically develop empirical models from multimodal satellite and field data sets. Machine learning can help construct nonlinear mappings between satellite measurements and water quality products and optimize in-situ data collection through mission planning. Experimental results are shown applying these techniques to map water quality metrics like chlorophyll-a and total suspended solids using MODIS satellite images of Lake Winnipeg.
The document discusses two NSF-funded research projects on intelligence and security informatics:
1. A project to filter and monitor message streams to detect "new events" and changes in topics or activity levels. It describes the technical challenges and components of automatic message processing.
2. A project called HITIQA to develop high-quality interactive question answering. It describes the team members and key research issues like question semantics, human-computer dialogue, and information quality metrics.
The document describes a project to create a continuous map of predicted above-ground biomass (AGB) for the Bonanza Creek Experimental Forest in Alaska using various data sources. The researchers collected field plot data on AGB, tree density, and basal area. They also obtained LiDAR and satellite imagery data. They developed simplified regression models and more complex spatial models to predict AGB across the forest, facing challenges with missing data and model accuracy. Future work could involve cross-validation and incorporating prediction uncertainties.
This document discusses the application of Geographic Information Systems (GIS) in horticulture.

The document concludes that GIS along with technologies like GPS and remote sensing will be important for improving farm practices and decision making in agriculture.
Classification accuracy analyses using Shannon’s EntropyIJERA Editor
There are many methods for determining the Classification Accuracy. In this paper significance of Entropy of
training signatures in Classification has been shown. Entropy of training signatures of the raw digital image
represents the heterogeneity of the brightness values of the pixels in different bands. This implies that an image
comprising a homogeneous lu/lc category will be associated with nearly the same reflectance values that would
result in the occurrence of a very low entropy value. On the other hand an image characterized by the
occurrence of diverse lu/lc categories will consist of largely differing reflectance values due to which the
entropy of such image would be relatively high. This concept leads to analyses of classification accuracy.
Although Entropy has been used many times in RS and GIS but its use in determination of classification
accuracy is new approach.
Outlier detection is very interesting, useful and challenging problem in the field of data mining. Because of
sparse data clustering algorithm which are based on distance will not work to find outliers in spatial data.
Problem of finding irregular feature in spatial data need to be explore. Many existing approaches have
been proposed to overcome the problem of outlier detection in spatial Geographic data. In this paper an
efficient clustering and density based outlier detection framework has been proposed. The process of
outlier detection has been categorized into two steps in the first step data has been clustered together based
on any density based DBSCAN algorithm and in the second stage outlier detection is performed using LOF.
The purpose is to perform clustering and outlier mining simultaneously to improve feasibility of framework.
To verify the efficiency and robustness of proposed method, comparative study of proposed approach and
several existing approaches are presented in detail, various simulation results demonstrate the
effectiveness of the proposed approach.

- Spatial autocorrelation measures the correlation of a variable with itself through space and can be positive or negative. It quantifies the degree of spatial clustering or dispersion of values across locations.
- Global measures identify overall patterns of clustering, while local measures identify specific clusters. Spatial weights defining neighbor relationships are required.
- Contiguity-based weights define neighbors based on shared boundaries, while distance-based weights use a threshold distance. Higher order weights incorporate indirect neighbors.
- Spatially lagged variables are weighted averages of neighboring values and are important for spatial autocorrelation tests and regression models.

Dandelion Hashtable: beyond billion requests per second on a commodity serverAntonios Katsarakis
This slide deck presents DLHT, a concurrent in-memory hashtable. Despite efforts to optimize hashtables, that go as far as sacrificing core functionality, state-of-the-art designs still incur multiple memory accesses per request and block request processing in three cases. First, most hashtables block while waiting for data to be retrieved from memory. Second, open-addressing designs, which represent the current state-of-the-art, either cannot free index slots on deletes or must block all requests to do so. Third, index resizes block every request until all objects are copied to the new index. Defying folklore wisdom, DLHT forgoes open-addressing and adopts a fully-featured and memory-aware closed-addressing design based on bounded cache-line-chaining. This design offers lock-free index operations and deletes that free slots instantly, (2) completes most requests with a single memory access, (3) utilizes software prefetching to hide memory latencies, and (4) employs a novel non-blocking and parallel resizing. In a commodity server and a memory-resident workload, DLHT surpasses 1.6B requests per second and provides 3.5x (12x) the throughput of the state-of-the-art closed-addressing (open-addressing) resizable hashtable on Gets (Deletes).

Essentials of Automations: Exploring Attributes & Automation ParametersSafe Software
Building automations in FME Flow can save time, money, and help businesses scale by eliminating data silos and providing data to stakeholders in real-time. One essential component to orchestrating complex automations is the use of attributes & automation parameters (both formerly known as “keys”). In fact, it’s unlikely you’ll ever build an Automation without using these components, but what exactly are they?
Attributes & automation parameters enable the automation author to pass data values from one automation component to the next. During this webinar, our FME Flow Specialists will cover leveraging the three types of these output attributes & parameters in FME Flow: Event, Custom, and Automation. As a bonus, they’ll also be making use of the Split-Merge Block functionality.
You’ll leave this webinar with a better understanding of how to maximize the potential of automations by making use of attributes & automation parameters, with the ultimate goal of setting your enterprise integration workflows up on autopilot.
High performance Serverless Java on AWS- GoTo Amsterdam 2024Vadym Kazulkin

Fueling AI with Great Data with Airbyte WebinarZilliz
This talk will focus on how to collect data from a variety of sources, leveraging this data for RAG and other GenAI use cases, and finally charting your course to productionalization.
How information systems are built or acquired puts information, which is what they should be about, in a secondary place. Our language adapted accordingly, and we no longer talk about information systems but applications. Applications evolved in a way to break data into diverse fragments, tightly coupled with applications and expensive to integrate. The result is technical debt, which is re-paid by taking even bigger "loans", resulting in an ever-increasing technical debt. Software engineering and procurement practices work in sync with market forces to maintain this trend. This talk demonstrates how natural this situation is. The question is: can something be done to reverse the trend?

12. Concept of Fuzzy K-means Clustering Source: J . Balkovič & G . Čemanová Credit: Sobocká et al., 2003
13. Example of Application of Fuzzy K-means Unsupervised Classification From: Burrough et al., 2001, Landscsape Ecology Note similarity of unsupervised classes to conceptual classes
14.
15. Supervised Classification Using Regression Trees From: Zhou et al., 2004 JZUS Note similarity of supervised rules and classes to typical soil-landform conceptual classes Note numeric estimate of likelihood of occurrence of classes
16. Supervised Classification Using Bayesian Analysis of Evidence From: Zhou et al., 2004 JZUS Note: ultimately this is just a way of establishing numerical measures of the likelihood of occurrence of each class to be predicted given the presence of a predictor class Note: the final, overall probability value is computed as a weighted average of the individual probabilities of each potential output class given each input class on n input maps
33. Lesson 8: Don’t Model What You Can Directly Map More Efficiently! Principle 1: Do not predict something that is easier to measure or map than to predict! So – if you can map it manually faster or better, do not hesitate to do so!
Basic concept Provide an overarching methodological framework that links individual components (bits) into an integrated whole whose functions interact intelligently to produce consistent outputs. An Open Soil Profiles Database (OSPD) A repository of global gridded covariate maps (World Grids) A linked library of complimentary functions and utilities (mostly but not exclusively produced using R) for manipulating and processing the preceding data sets to automatically produce models and maps of soil property spatial patterns (and uncertainties) according to GlobalSoilmap.net specifications. A platform and utilities for discovering, displaying and retrieving grid maps of soil properties for any area of interest. Support capture of existing legacy data at the node level Produce consistent soil property maps across entire nodes 08/02/12
