A KALMAN FILTERING TUTORIAL FOR UNDERGRADUATE STUDENTSIJCSES Journal
This paper presents a tutorial on Kalman filtering that is designed for instruction to undergraduate
students. The idea behind this work is that undergraduate students do not have much of the statistical and
theoretical background necessary to fully understand the existing research papers and textbooks on this
topic. Instead, this work offers an introductory experience for students which takes a more practical usage
perspective on the topic, rather than the statistical derivation. Students reading this paper should be able
to understand how to apply Kalman filtering tools to mathematical problems without requiring a deep
theoretical understanding of statistical theory.
This presentation speak's about Kalman Filter. In the presentation arithmetic behind Kalman filter is defined. The presentation is concluded with application example of Kalman filter.
This presentation on Recurrent Neural Network will help you understand what is a neural network, what are the popular neural networks, why we need recurrent neural network, what is a recurrent neural network, how does a RNN work, what is vanishing and exploding gradient problem, what is LSTM and you will also see a use case implementation of LSTM (Long short term memory). Neural networks used in Deep Learning consists of different layers connected to each other and work on the structure and functions of the human brain. It learns from huge volumes of data and used complex algorithms to train a neural net. The recurrent neural network works on the principle of saving the output of a layer and feeding this back to the input in order to predict the output of the layer.

A NEW METHOD OF SMALL-SIGNAL CALIBRATION BASED ON KALMAN FILTERijcseit
The basic principle of Kalman filter (KF) is introduced in this paper, based on which, it presents a new
method for high precision measurement of small-signal instead of the unreal direct one. We have designed a
method of multi-meter information infusion. With this method, we filter the measured value of a type of
special equipment and extract the optimal estimate for true value. Experimental results show that this
method can effectively eliminate the random error of the measurement process. The optimal estimate error
meets the basic requirements of conformity assessment, 3푈95 ≤ 푀푃퐸푉. This method can provide an
algorithm reference for the design of automatic calibration equipment.

Relative Study of Measurement Noise Covariance R and Process Noise Covariance...iosrjce
In this paper is study the role of Measurement noise covariance R and Process noise covariance Q.
As both the parameter in the Kalman filter is a important parameter to decide the estimation closeness to the
True value , Speed and Bandwidth [1] . First of the most important work in integration is to consider the
realistic dynamic model covariance matrix Q and measurement noise covariance matrix R for work in the
Kalman filter. The performance of the methods to estimate and calculate both of these matrices depends entirely
on the minimization of dynamic and measurement update errors that lead the filter to converge[2]. This paper
evaluates the performances of Kalman filter method with different adaptations in Q and in R. This paper
perform the estimation for different value of Q and R and make a study that how Q and R affects the estimation
and how much it differ to true value to the estimated value by plot in graph for different value of Q and R as
well as we give a that give the brief idea of error in estimation and true value by the help of the MATLAB.

Search and Society: Reimagining Information Access for Radical FuturesBhaskar Mitra
The field of Information retrieval (IR) is currently undergoing a transformative shift, at least partly due to the emerging applications of generative AI to information access. In this talk, we will deliberate on the sociotechnical implications of generative AI for information access. We will argue that there is both a critical necessity and an exciting opportunity for the IR community to re-center our research agendas on societal needs while dismantling the artificial separation between the work on fairness, accountability, transparency, and ethics in IR and the rest of IR research. Instead of adopting a reactionary strategy of trying to mitigate potential social harms from emerging technologies, the community should aim to proactively set the research agenda for the kinds of systems we should build inspired by diverse explicitly stated sociotechnical imaginaries. The sociotechnical imaginaries that underpin the design and development of information access technologies needs to be explicitly articulated, and we need to develop theories of change in context of these diverse perspectives. Our guiding future imaginaries must be informed by other academic fields, such as democratic theory and critical theory, and should be co-developed with social science scholars, legal scholars, civil rights and social justice activists, and artists, among others.
Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

Gaussian Processes
The estimator performs well even if the process
is not gaussian.
Temperature changes behave as a uniform
(non-gaussian) process with zero mean
19. Conclusions
Sensor data fusion can be easily implemented using
Kalman filters.
For filter design, changes in temperature are modeled as a
gaussian process. However, the filter performs well even
when used in other probabilistic processes.
Sensor fusion through Kalman filtering significantly
improves the on-line estimation reducing the effect of
sensor noise and bias.
Research goes on for the simultaneous estimation of
several variables.
