Faith, Edafetanure-Ibeh, Tamarauefiye, Evah Patrick, Uyi, Mark Uwuoruya
The aim of attending an educational institution is learning, which in turn is sought after for the reason of independence of thoughts, ideologies as well as physical and material independence. This physical and material independence is gotten from working in the industry, that is, being a part of the independent working population of the country. There needs to be a way by which students upon graduation can easily adapt to the real world with necessary skills and knowledge required. This problem has been a challenge in some computer science departments, which after effects known after the student begins to work in an industry. The objectives of this project include: Designing a web based chat application for the industry and computer science department, Develop a web based chat application for the industry and computer science and Evaluate the web based chat application for the industry and computer science department. Waterfall system development lifecycle is used in establishing a system project plan, because it gives an overall list of processes and sub-processes required in developing a system. The descriptive research method applied in this project is documentary analysis of previous articles. The result of the project is the design, software a web-based chat application that aids communication between the industry and the computer science department and the evaluation of the system. The application is able to store this information which can be decided to be used later. Awareness of the software to companies and universities, implementation of the suggestions made by the industry in the computer science curriculum, use of this software in universities across Nigeria and use of this not just in the computer science field but in other field of study

Compressive Feature Learning Robert West Department of Computer Science Department of Computer Science Stanford University
This paper addresses the problem of unsupervised feature learning for text data. Our method is grounded in the principle of minimum description length and uses a dictionary-based compression scheme to extract a succinct feature set. Specifically, our method finds a set of word k-grams that minimizes the cost of reconstructing the text losslessly. We formulate document compression as a binary optimization task and show how to solve it approximately via a sequence of reweighted linear programs that are efficient to solve and parallelizable. As our method is unsupervised, features may be extracted once and subsequently used in a variety of tasks. We demonstrate the performance of these features over a range of scenarios including unsupervised exploratory analysis and supervised text categorization. Our compressed feature space is two orders of magnitude smaller than the full k-gram space and matches the text categorization accuracy achieved in the full feature space. This dimensionality reduction not only results in faster training times, but it can also help elucidate structure in unsupervised learning tasks and reduce the amount of training data necessary for supervised learning.

On-the-Job Learning with Bayesian Decision Theory Arun Chaganty Department of Computer Science Department of Computer Science Stanford University
Our goal is to deploy a high-accuracy system starting with zero training examples. We consider an on-the-job setting, where as inputs arrive, we use real-time crowdsourcing to resolve uncertainty where needed and output our prediction when confident. As the model improves over time, the reliance on crowdsourcing queries decreases. We cast our setting as a stochastic game based on Bayesian decision theory, which allows us to balance latency, cost, and accuracy objectives in a principled way. Computing the optimal policy is intractable, so we develop an approximation based on Monte Carlo Tree Search. We tested our approach on three datasets--named-entity recognition, sentiment classification, and image classification. On the NER task we obtained more than an order of magnitude reduction in cost compared to full human annotation, while boosting performance relative to the expert provided labels.

Talk about a blast from the past! Two of the world's first desktop computers dating back over 50 years are discovered during a house clearance in London
You might think your desktop computer is old, but that's nothing compared to these ancient relics. Two of the world's very first desktop computers have been discovered during a house clearance in London. The chance discovery revealed two of only three surviving Q1 computers anywhere in the world. Although it is often now overlooked, the Q1 paved the way for the computers we have today when it was launched more than 50 years ago. Brendan O'Shea, head of Just Clear which discovered the items, says: 'Never did I imagine that we'd find something so important to the field of technology and the history of computing.'
Real Time Human Detection by Unmanned Aerial Vehicles
Guettala, Walid, Sayah, Ali, Kahloul, Laid, Tibermacine, Ahmed
One of the most important problems in computer vision and remote sensing is object detection, which identifies particular categories of diverse things in pictures. Two crucial data sources for public security are the thermal infrared (TIR) remote sensing multi-scenario photos and videos produced by unmanned aerial vehicles (UAVs). Due to the small scale of the target, complex scene information, low resolution relative to the viewable videos, and dearth of publicly available labeled datasets and training models, their object detection procedure is still difficult. A UAV TIR object detection framework for pictures and videos is suggested in this study. The Forward-looking Infrared (FLIR) cameras used to gather ground-based TIR photos and videos are used to create the ``You Only Look Once'' (YOLO) model, which is based on CNN architecture. Results indicated that in the validating task, detecting human object had an average precision at IOU (Intersection over Union) = 0.5, which was 72.5\%, using YOLOv7 (YOLO version 7) state of the art model \cite{1}, while the detection speed around 161 frames per second (FPS/second). The usefulness of the YOLO architecture is demonstrated in the application, which evaluates the cross-detection performance of people in UAV TIR videos under a YOLOv7 model in terms of the various UAVs' observation angles. The qualitative and quantitative evaluation of object detection from TIR pictures and videos using deep-learning models is supported favorably by this work.

Embedding-based Retrieval with LLM for Effective Agriculture Information Extracting from Unstructured Data
Peng, Ruoling, Liu, Kang, Yang, Po, Yuan, Zhipeng, Li, Shunbao
Information extraction (IE) refers to the process of extracting information from unstructured text and transform it into structured data. Nowadays, in an information era, the rapid increase in the amount of data has made this type of task increasingly important. IE is labour-intensive and time-consuming, so lots of domains have switched to automatic or semi-automatic IE Wang et al. [2018] Saggion et al. [2007]. The Internet provides a vast amount of information for agriculture, but the lack of effective data processing methods leads to that much agricultural information remains unarchived, buried in news, papers, and government and organization websites. This may mainly be due to the shortage of annotated corpora Nismi Mol and Santosh Kumar [2023]. These documents cannot be easily analyzed or queried in their raw form and require some form of information extraction to be easily utilised in applications. Searching and managing this unstructured information efficiently is not only a difficult challenge for farmers, but for agriculture professionals as well.
HIVA: Holographic Intellectual Voice Assistant
Isaev, Ruslan, Gumerov, Radmir, Esenalieva, Gulzada, Mekuria, Remudin Reshid, Doszhanov, Ermek
Holographic Intellectual Voice Assistant (HIVA) aims to facilitate human computer interaction using audiovisual effects and 3D avatar. HIVA provides complete information about the university, including requests of various nature: admission, study issues, fees, departments, university structure and history, canteen, human resources, library, student life and events, information about the country and the city, etc. There are other ways for receiving the data listed above: the university's official website and other supporting apps, HEI (Higher Education Institution) official social media, directly asking the HEI staff, and other channels. However, HIVA provides the unique experience of "face-to-face" interaction with an animated 3D mascot, helping to get a sense of 'real-life' communication. The system includes many sub-modules and connects a family of applications such as mobile applications, Telegram chatbot, suggestion categorization, and entertainment services. The Voice assistant uses Russian language NLP models and tools, which are pipelined for the best user experience.

Fast and Provably Good Seedings for k-Means Mario Lucic Department of Computer Science Department of Computer Science ETH Zurich
Seeding - the task of finding initial cluster centers - is critical in obtaining highquality clusterings for k-Means. However, k-means++ seeding, the state of the art algorithm, does not scale well to massive datasets as it is inherently sequential and requires k full passes through the data. It was recently shown that Markov chain Monte Carlo sampling can be used to efficiently approximate the seeding step of k-means++. However, this result requires assumptions on the data generating distribution. We propose a simple yet fast seeding algorithm that produces provably good clusterings even without assumptions on the data. Our analysis shows that the algorithm allows for a favourable trade-off between solution quality and computational cost, speeding up k-means++ seeding by up to several orders of magnitude.

Wavelet Score-Based Generative Modeling Simon Coste Computer Science Department, Computer Science Department, ENS, CNRS, PSL University ENS, CNRS, PSL University Valentin De Bortoli
Score-based generative models (SGMs) synthesize new data samples from Gaussian white noise by running a time-reversed Stochastic Differential Equation (SDE) whose drift coefficient depends on some probabilistic score. The discretization of such SDEs typically requires a large number of time steps and hence a high computational cost. This is because of ill-conditioning properties of the score that we analyze mathematically. Previous approaches have relied on multiscale generation to considerably accelerate SGMs. We explain how this acceleration results from an implicit factorization of the data distribution into a product of conditional probabilities of wavelet coefficients across scales. The resulting Wavelet Score-based Generative Model (WSGM) synthesizes wavelet coefficients with the same number of time steps at all scales, and its time complexity therefore grows linearly with the image size. This is proved mathematically for Gaussian distributions, and shown numerically for physical processes at phase transition and natural image datasets.
