Energiförbrukningsfeedback för gaffeltruckförare som använder maskininlärning och kontrafaktisk förklaring / Energy Consumption Feedback for Forklift Drivers Using Machine Learning and Counterfactual ExplanationZirak Hassankiadeh, Heidar, Thenguvila Koshy, Priyan January 2024 (has links)
Counterfactual Explanations (CE) is a type of eXplainable Artificial Intelligence (XAI) that addresses the common question of what options a user has to achieve a desired output. In this thesis, the authors propose utilizing the CE technique on regression tasks with a reject option to provide feedback to forklift drivers regarding their energy usage. Recent developments in CE shows that most of the research on CE focuses on classification tasks. Hence, the research question addresses how CE techniques can be used for regression tasks, particularly feedback-providing applications. The data was collected from the Toyotalab for forklifts using a Controller Area Network (CAN). Forklifts are an important component in logistics operations and the demand for them is increasing day by day due to the increasing trend of e-commerce and express delivery. Optimizing their energy usage can lead to significant energy savings. The study is in the direction of providing only the important feedback to the driver by using a reject option as a decision making system. The data is pre-processed and used to train an Machine Learning (ML) model and is used to predict future energy consumption based on the current values. Evaluation of results shows that theCE method exhibits slower performance compared to Local Interpretable Model-Agnostic Explanations(LIME) and SHapley Additive exPlanations (SHAP). However, it demonstrates a high degree of stability in its results. Additionally, the results show that if the driver follows the suggestions proposed by the reject option driven CE, substantial energy savings can be achieved. This work can also be extended to other regression applications where feedback is required.

Comprehensive support for developing graphical highly interactive user interface systemsKeh, Huan-chao 29 July 1991 (has links)
The general problem of application development of interactive GUI applications
has been addressed by toolkits, libraries, user interface management systems, and more
recently domain-specific application frameworks. However, the most sophisticated
solution offered by frameworks still lacks a number of features which are addressed by
this research:
1) limited functionality -- the framework does little to help the developer
implement the application's functionality.
2) weak model of the application -- the framework does not incorporate a
strong model of the overall architecture of the application program.
3) representation of control sequences is difficult to understand, edit, and
reuse -- higher-level, direct-manipulation tools are needed.
We address these problems with a new framework design called Oregon
Speedcode Universe version 3.0 (OSU v3.0) which is shown, by demonstration, to
overcome the limitations above:
1) functionality is provided by a rich set of built-in functions organized as a
class hierarchy,
2) a strong model is provided by OSU v3.0 in the form of a modified MVC
paradigm, and a Petri net based sequencing language which together form
the architectural structure of all applications produced by OSU v3.0.
3) representation of control sequences is easily constructed within OSU v3.0
using a Petri net editor, and other direct manipulation tools built on top of
the framework.
In ddition:
1) applications developed in OSU v3.0 are partially portable because the
framework can be moved to another platform, and applications are
dependent on the class hierarchy of OSU v3.0 rather than the operating
system of a particular platform,
2) the functionality of OSU v3.0 is extendable through addition of classes,
subclassing, and overriding of existing methods.
The main contribution of this research is in the design of an application
framework that uses Petri nets as the computational model of data processing in the
synthesized application. OSU v3.0 is the first framework to formalize sequencing, and
to show that complex GUI applications can indeed be quickly and reliably produced
from such a framework. / Graduation date: 1992

The effectiveness of three dimensional interactionBoritz, James 05 1900 (has links)
Most interaction with computers today takes place in a two dimensional environment.
Even when using three dimensional graphics applications, input is often still restricted
to two dimensions. Many believe that the use of three dimensional input devices will alleviate
this restriction and allow for a much more natural human-machine dialog.
This thesis seeks to establish how factors dealing with visual feedback and task structure
affect the ability to perform interactive tasks in a three dimensional virtual environment.
The factors investigated were stereoscopic vision, motion parallax, stimulus arrangement
and stimulus complexity. Four tasks were studied. These tasks were: point location, docking,
line tracing and curve tracing. All the tasks used a six degree of freedom input device
to control a pointer in a three dimensional virtual environment.
Four experiments corresponding to the four tasks were conducted to investigate these
factors. Among other things the results showed the following. Stereoscopic vision provided
a strong benefit to positioning-based tasks, but this benefit was weakened in the case of tracing
tasks. Motion parallax via head-tracking often had no effect upon task performance and
where an effect was found it was often detrimental. The position of stimuli influenced performance
across all of the tasks. The orientation of stimuli influenced performance in the
task in which it was varied.
