Abstract:

Phylogeny is the evolutionary history of a species or group of organisms. Evolutionary trees can be analogized to graph trees, thus determination of these structures aids in inferring the evolutionary history of groups of organisms, extant and extinct. K-leaf power graphs enhance the ability of researchers to map paralogous and xenologous speciation events in what is a considerably difficult area to correctly predict past relationships.

Forbidden subgraph characterization is a method by which to characterize a graph class with a set of graphs that do not belong to that class. Identification of minimal forbidden induced
subgraphs is one method of characterizing the k-leaf powers of graph trees. A tree is a k-leaf power if, and only if, the leaves are connected by at most distance k. Structures for 2-leaf, 3-leaf, and 4-leaf powers are well understood, however, there does not exist a published list of forbidden subgraph leaf powers for values of k ≥ 4. In service of cladistics, k-leaf powers are frequently edited by adding or removing nodes and edges to the closest “proper” representation of a pairwise comparison of groups of organisms.

We demonstrate a deterministic, reductionist approach to generating 4-leaf, 5-leaf, and 6-leaf powers using Python, the graph library Networkx, and the Nauty suite of graph generation and labelling programs. The list of non-k-leaf powers in this range has not been proven finite, so this approach does not cover all possible structures should the list be infinite.

Algorithmic Trading and Short-term Forecast for Financial Time Series with Machine Learning Models

Time & Date:  4 p.m., Tuesday, March 29, 2022
Location: Room L318 (up to 16 peoples), Langara College, 100 West 49th Avenue, Vancouver B.C., Canada V5Y 2Z6 and Online (Via email and Registration below)

Abstract: A profitable algorithmic stock trading algorithm benefits from a forecasting system that can produce accurate short-term forecasts. Based on this premise, we proposed to build up our previous experience in building short-term forecasting models using machine learning models. The research project aims to develop effective algorithmic trading algorithms based on accurate short-term forecasts for financial time series using machine learning models. The project focuses on three research activities: (1) building a data warehouse containing the targeted financial time series and other time series considered valuable as input to the machine learning models. Data acquisition, processing, and staging routines that are required to feed the data warehouse dynamically are evaluated and developed. A data visualization and business intelligence layer is also built on top of the data warehouse; (2) a short-term forecasting model based on machine learning is developed using the various time-series data from the data warehouse. Machine learning algorithms such as neural network, random forecast, support vector regression, XGBoost, and long short-term memory (LSTM) are evaluated in conjunction with several performance criteria to identify the most accurate model from a short-term trading perspective; (3) an automated evaluation system is developing to assess the effectiveness of existing algorithmic short-term trading strategies. Novel algorithms are also developed and evaluated using the evaluation system and the short-term forecast machine learning model.

The current research project was motivated by 3 NSERC funded projects:

  • May 2021 – May 2023. NSERC CCI ARD2: Utilities, Smart metering, Data warehouse, Natural Language Processing, Speech-to-text. Industrial Client: Harris SmartWorks.
  • June 2020 – March 2021. A novel approach to COVID-19 Impact Analysis and Reporting for Utilities. Host institution: Langara College. Industrial Client: Harris SmartWorks.
  • 2016 – 2019. NSERC CCI ARD2 (477506-14): GPN-Perf2: Game private networks and game servers performance optimization. Industrial Client: WTFast.

The need for a Corporate Endpoint Security System

Time & Date: Moved to 2022 (bad road conditions in BC).
Location: Room E207, 1000 KLO Rd., Kelowna, BC (at Okanagan College) and Online (TBA via emails and vTools)
Registration is open now: https://events.vtools.ieee.org/m/294130

Abstract: Information security is to protect information from unauthorized use, disruption or destruction. There are three categories of control used to secure information: management, physical and operational security. Endpoint Security is the practice of securing endpoints or entry points of end-user devices, and falls under this operational security category, being one of the security topologies applied to a subset of systems like desktops, laptops or other mobile devices. The four common attack vectors of endpoint security are shadow IoT devices, BYOD/mobile devices, insider threat and insecure applications. Some consequences of endpoint security failure are theft and sale of the customer and member list to competitors, payroll data leaked to employees, private information of customers or employees leaked, and your data encrypted and held for ransom. Any of the resulting financial, regulatory and reputational impacts could undermine a company’s viability. Endpoint security is no longer optional for any size of the enterprise.

Talk Abstract:

DevOps has become a buzzword in the last few years. A number of companies, and development and product teams achieved quite impressive results in this area, making cultural changes, transforming their processes and practices, and introducing new roles, tools and techniques.

In this presentation, we will introduce the world of mainframe and problems legacy technologies face in today’s world. However, mainframe-based software has been designed several years ago; its development still requires well organized and automated processes. We will talk about solutions and technologies required for DevOps transformation on a mainframe and how we implement the changes.

During the session you will learn:
– Mainframe position in today’s technology world
– Which skills are required for software development and support on a mainframe
– What is DevOps and DevOps for mainframe
– What tools are used for building CI/CD pipelines around mainframe infrastructure
– Things to factor when selecting tools for DevOps
– Approaches to DevOps implementation in large organizations

Speakers Biography: 

Yuliya has been working at IBA Group since 2017. Her current position is a DevOps Engineer & Scrum Master. Previously – SDET on Python. She is engaged in Z stack development, DevOps building, agile engineering, and test automation. In addition, she is a Scrum Master for two big scrum teams and an active conference speaker. In past years, she solved problems of building and testing backends and infrastructure of z teams and created CI with related infrastructure for a complex mainframe system that included C, Java, DB2, and TWSz.

For the past three years, Tatiana has been working on CI/CD development for mainframe-based applications. She is engaged in test infrastructure development and support.
