An improved &lt;i&gt;k&lt;/i&gt;NN text classification method

This paper proposes an improved kNN text classification method. The kNN algorithm in vector space models (VSM) has several limitations, such as occupying excessive storage space and all dimensions in the kNN algorithm share the same weight, making classification inaccurate. To solve these problems, this paper proposes a SOM neural network with principal component weighting. In this model, the principal component analysis process is embedded into the SOM neural network. Specifically, principal component analysis is used to extract the main feature components of the assessed target. Then, it is inputted into the network for computation. Meanwhile, variance contribution rates of principal components are introduced into the Euclidean distance function in the forms of weights. Using the principal component weighting SOM algorithm to compute the weights of VSM dimensions together with the kNN algorithm could effectively reduce dimensions of a vector space, and increase the precision and speed of the kkNN text classification method.

Causal Discovery of Linear Non-Gaussian Acyclic Model with Small Samples

Linear non-Gaussian Acyclic Model (LiNGAM) is a well-known model for causal discovery from observational data. Existing estimation methods are usually based on infinite sample theory and often fail to obtain an ideal result in the small samples. However, it is commonplace to encounter non-Gaussian data with small or medium sample sizes in practice. In this paper, we propose a Minimal Set-based LiNGAM algorithm (MiS-LiNGAM) to address the LiNGAM with small samples. MiS-LiNGAM is a two-phase and greedy search algorithm. Specifically, in the first phase, we find the skeleton of the network using the regression-based conditional independence test, which helps us reduce the complexity in finding the minimal LiNGAM set of the second phase. Further, this independence test we applied guarantees the reliability when the number of conditioning variables increases. In the second phase, we give an efficient method to iteratively select the minimal LiNGAM set with the skeleton and learn the causal network. We also present the corresponding theoretical derivation. The experimental results on simulated networks and real networks are presented to demonstrate the efficacy of our method.

Exploring the prevalence of the sexually transmitted marks phenomenon in higher education institutions

Countries steadfastly pursue academia as a necessary step towards socio-economic development, which places a mandate on institutions of higher learning to stir host-country economies through university deliverables. In Zimbabwe, this entails the Ministry of Higher and Tertiary Education, Science and Technology Development’s ‘doctrine’ spelling out the philosophy of ‘Education 5.0’ which emphasises teaching/learning, research, community engagement, innovation, and commercialisation of goods and services. However, academic dishonesty, such as that through ‘sexually transmitted marks’ (STM), threatens the realisation of such mandates. Although the norm is that such sexual transactions are initiated by academics, evidence shows students also initiate such relationships. Consequently, efforts to eliminate this threat to academic integrity should not only focus on lecturers, but also be extended to students. This paper contributes towards unmasking experiences of STM between male lecturers and female students, female lecturers and male students, and female students and male students, as determined from former university students and university alumni in Bulawayo. Exposing these practices allows for open consultation and adoption of good practices from similar institutions worldwide.&#x0D; Significance:&#x0D; &#x0D; The majority of respondents all attested to having experienced STM directly or indirectly during their years of study.&#x0D; An explicit STM regulation policy targeting all actors across universities is needed.&#x0D;

Quadrotor Singularity Free Modeling and Acrobatic Maneuvering

Abstract When an unmanned aerial vehicle (UAV) navigates reactively over an unknown land, it may encounter terrains that require aggressive maneuver to keep the designed coasting speed while staying on the path. During this execution of the aggressive maneuver, the UAV can experience singularity. In this article, a vertical loop aggressive maneuver performed by a quadrotor UAV is investigated. Due to the physical configuration of the quadrotor, the conventional modeling and tracking control method may not be desirable if certain requirements, such as fast coasting speed and sharp turns, are imposed. In this work, a new modeling and maneuver control method, which is called the controlled loop path following (CLPF) method is developed. As shown in numerical examples, the proposed singularity-free model and control method enables a quadrotor to be operated in aggressive maneuverability with features like automatic flipping and precise trajectory following.

Cisco Packet Tracer was then used to carry out the simulation process and the results was found to be in tune with the overall objective of the design.
Augustus Scriptus: Referencing the ‘real’ in Propertius

The main aim of this article is to understand how Augustus is written into life in the story-world of Propertius. It traces the development of the character in the story-world over time with due regard to the parallel historical narratives that were told about the historical Augustus. The investigation proceeds from a content analysis of the incidence of references (overt and oblique) to Augustus Caesar in the extant text of Propertius. This approach assumes that quantitative data, that is, frequency of incidence, spatial or temporal dimensions of incidence and the location of a reference in the broader context, are important indicators of meaning. The investigation presents its content analysis and the interpretation of this analysis. The investigation also relies to a certain extent on narratological analytical concepts, because Augustus is written into life by the Propertian text as a character which exists, to a certain extent at least, in a narrative. The investigation concludes that Augustus is not a fully developed character in the Propertian texts. Nevertheless, Augustus is revealed to be a distant ruler mostly associated with military authority and wealth; at some instances, he is regarded as a messianic figure, which is also present in other poets. Most notably, the content analysis reveals a consistent engagement between the speaker in the Propertian poems and the power wielded by Augustus.
