Big Data Analitic Tools

Big Data Analitic Tools

Unlocking new insights from complex, vast, diverse, and massive quantities of data to accelerate digital transformation, innovation, and social sustainability is the primary objective of Big Data Analytics. It uses a palette of advanced techniques and approaches from emerging fields such as Data Mining, Machine Learning and Deep Learning for extracting valuable information. Various tools support and optimize knowledge discovery engineering.

In such a context, the short-term training aims to broaden the students’ interest in data-driven projects as a novel paradigm in Industry 4.0 and Society 5.0, by answering a series of questions:
 What acts in the Big Data value-chain paradigm?
 What are the key technologies behind Big Data Analytics (BDA)?
 What tools and software enable meaningful insight from big data?
 What tools and software can be used for BDA with no or minimal coding skills?

Besides these questions, the training provides practical guides to particular tools that support and automate end-to-end data analytics, from data collection, cleansing, and transformation through model building, evaluation, and tuning, to visualization and communication of results.

The training is competences oriented utilizing learning-by-doing and case-based methods. The course is offered to computer science students from University of Nis (Serbia), University of Library Studies and Information Technologies (Bulgaria) and University of Bielsko-Biala (Poland).

Article: Ensemble of RNN classifiers for activity detection using smartphone and supporting nodes

The dataset was provided for classification of activity using sensors placed in four places: waist, chest, arm and leg.

The dataset contains eight classes:

  • walking in normal paste, where legs and arms are moving without any luggage,
  • jogging in moderate paste, where limb movement is faster, and the body is moving more dynamically,
  • squats, where a person is performing squats in place and arms holding a balance,
  • jump, where a person jumps in place as a part of aerobic exercises,
  • laying, where a person is lying on his back, and major movement corresponds to chest breathing,
  • arms swing, where the arms are moving during the exercise or housework,
  • siting, where the person sits at the desk and performs simple writing (office) activities.
  • standing in place, where only natural body balance can be registered.

NodeJS and BigData

NodeJS and BigData

Nowadays, the Big Data can be found in most of modern organisation and companies. Its utilisation gives an advantage over competitors and allows to adapt to new trends. There is no surprise that established organizations, to follow a trend, are shifting to Node.js platforms from their legacy systems. Node.js is used by companies like PayPal, Yahoo, eBay, Netflix.

So, what is NodeJS?

Its real time web application using push technology over web sockets. It allows two-way connections (client and server). Advantage of Node.js is JavaScript language that makes easier to build both back-end and front-end using the same code. Node.js uses non-blocking, event driven I/O to offer efficiency and remain lightweight in terms of in-memory usage. It is especially effective processing multiple requests (with not high computing complexity) that makes it perfect tool for ingestion phase of Big Data pipelines.

New MSc thesis concerning Big Data in UBB

New MSc thesis concerning Big Data in UBB

Today on University of Bielsko-Biala our graduate defend its MSc thesis.

The following publication ‘Sentiment and stock market analysis of listed companies using Big Data tools’ introduces the topic of Big Data with sentiment analysis. Big Data is having an increasingly important role in the modern world over time. With the help of huge data sets, many companies are able to predict customer demand and create personalised offers for them, or even react in advance to possible production failures. However, working with Big Data brings many challenges. Processing, storing and analysing huge sets of information requires special technologies to handle huge data records, as ordinary tools would not be able to handle such a amount of data.
One extensive source of Big Data is social networks. Users of such applications leave a lot of information about themselves, which is stored in extensive data stores, which correctly analysed, helps to present relevant offers, advertisements, information specifically personalised and designed exactly for the user.
In this study, research was carried out analysing the impact of Twitter users’ online statements on the share prices of selected companies. The research work was carried out over a period of one month. Conclusions were also presented for each company analysed.
However, the result of the research does not indicate a direct connection between the sentiment of the users’ statements and the increase or decrease in the value of the shares of the companies in question on the stock exchange. With such a complex process as stock market asset valuation, it should also be analysed with other factors, such as company valuations or the current global economic situation, which sets further directions for future work.
