Data science projects to improve your skills

In this article, we will discuss data science technologies and review data science projects.

What skills do data science specialists need?

Information is the main asset in the modern world. The amount of data is constantly growing and the ability to work effectively with them; companies and organizations gain additional benefits. The main requirements for working with data – are to ensure their receipt, processing, storage, protection, and availability of the specified parameters, at the time required to perform tasks.

Machine learning algorithms have been developing rapidly in recent years. More and more areas of human activity are becoming tied to the opportunities provided by Data Science. But widespread naturally entails increased requirements for professionals and the results of their work. Forecasts should be as accurate as possible, programs – perfect. We have produced more data in the past ten years than we have done before. Therefore, we need to analyze this data and find patterns using Machine Learning methods. Specialists in this field, data analysts, work with large amounts of data, extracting useful information from them.

Data science combines several related disciplines. These are programming, mathematics and statistics, business analytics, and machine learning.

A beginner Data Scientist should have 4 basic skills:

  • Programming, which includes: Python (basics, data structures, and understanding of REST); Git; SQL;
  • mathematics is at the heart of all ML algorithms, in order to learn ML with understanding;
  • in Machine Learning and Deep Learning, you need to understand the basic models and algorithms, what tasks they solve, and also the libraries and frameworks that are used for this;
  • Docker basics, docker-compose, and a little about CI / CD, for example, Travis or Gitlab CI.

Five basic steps in working with data

  • Search for channels where you can collect data, and the choice of methods for obtaining them.
  • Validation, leveling of anomalies that do not affect the result and interfere with further analysis.
  • Studying data, confirming assumptions.
  • Presentation of information in an understandable form: graphs, diagrams.
  • Data-driven decision-making. For example, changing the marketing strategy, increasing the company’s budget.

Data science projects to improve your skills

Projects of Data science play a significant role in today`s programming world. The specialists of this area mostly use the following kinds of projects:

  • visualization projects
  • research Data Analysis Projects
  • forecasting modeling

Advanced visualization – the most visual representation of data using various interactive images, diagrams, and graphs (instead of traditional tables).  Modeling, forecasting, and research of data – these tools are designed to help the company classify data, form their own nominal and quantitative scales, as well as use for their analysis a developed mathematical apparatus.

Data Science contains a significant experimental component, for which it is necessary to have both the subject area of analysis and software tools for working with data.


How to find best secure file hosting

Sometimes there are situations when storing data requires something more reliable than a simple external drive, such as file hosting. But there are many file-sharers now and it is difficult to choose the best one. In this article, we will look at the most popular file-sharing services like Secure File Pro.

What is file hosting?

Availability of information is one of the criteria on which work on the Internet is based. The ability to access your own files, photos, videos, regardless of the device is due to special services, called file hosting.

Hosting providers allow their users with the resources necessary to host information on the server. The main function of hosting is to save the site on servers and ensure that visitors are always available to it. Therefore, the choice of an Internet company providing this service should be approached responsibly. Without high-quality and reliable hosting, the site will not be publicly available to users. The site will be slow; search engines will not be able to index it.

File hosting not only saves space on your computer. There is a possibility of rapid dissemination of a significant amount of information. All you have to do is send the link to a person or group of people, and they’ll have access to the files right away. In addition, there is the possibility of sharing information, editing, supplementing.

How to choose secure file hosting?

Web developers are looking for hosting services for their projects that meet the following requirements:

  • Speed and stability
  • Maximum Possible Continuous Site Operation Time
  • The optimal amount of free disk space
  • Possibility to increase the amount of memory for an additional fee
  • High-quality support service, preferably 24/7

Alternative options of File hosting

The variety of hosting services for storing information on the Internet is great. Each user chooses the service that best meets his requirements, convenient for him, understandable in work.

The list of the best File hosting services includes the following:

  • This file hosting is available to owners of almost any OS. Information is stored thanks to 256-bit AES and SSL encryption. Access links are blocked not only by a password but also by a temporary restriction;
  • Google Drive. You can not only save data that is important to you but also share it with other users within the network. Suitable for storing more than 35 different data formats, including audio and video materials;
  • It has Drag & Drop support, increased security because thanks to AES files are securely protected by the extension directly in the browser.
  • You can back up important documents and files online. Deleted files on the system are stored in the cloud, so they are protected from accidental erasure from the main storage medium;
  • Secure File Pro. Conquered users with a minimalist design, thoughtful and simple interface. Registration on the service is not required. You can immediately download files weighing up to 30 GB, and distribute links to colleagues and acquaintances.

What is a Virtual Data Room for business

In this article, we give the answer to the question: what is the Virtual Data Room and discuss the purpose of using such a tool.

What is the Data Room?

Virtual Data Room is a platform, which provides authorized users with access to a secure database of documents, in accordance with their access rights. It is a unique combination of existing company documentation management systems and web content management systems. The essence of this development is that the company’s confidential data is stored clearly, structured in electronic form.

Unlike FTP, which is used to transmit information in an unprotected form, VDR exchanges data using the E2E encryption principle using secure transport protocols SSL or TLS, which ensures maximum security of data exchange between the server and the agent, protecting them from MITM attacks.

The most common uses of Virtual Data Rooms include:

  • Corporate storage of documents
  • Communication board
  • Secure document exchange
  • Mergers or acquisitions
  • Fundraising
  • Initial public offering
  • Strategic partnerships
  • Audits
  • Increase in venture capital
  • Intellectual property management

How does it work?

Let’s analyze how VDR works on the side of the owner of the document and an external user. There are the following stages:

  • Agent software is installed on the workstation, after which the encryption keys are exchanged between the server and the client. It is possible to work with a virtual data room without installing an agent – using a web browser;
  • The administrator or the user has the necessary rights, selects a directory for synchronizing documents with the corporate data warehouse;
  • Data in the synchronized directory becomes available on the user’s desktop PC and on authorized mobile devices;
  • If necessary, the user in addition to virtual data rooms can create workspaces – shared folders for collaboration with documents with their employees.


How to choose the right Data Room?

There are several factors you need to take into account when choosing a VDR.

Safety. Of course, this aspect will interest you the most. It is important to choose a developer who stores all the information himself and does not give it to subcontractors. Well, and certification, of course. Plus reviews, clients, etc.

Convenience and functionality. Here you need to take into account the format of the files that the system can work with, is it possible to download the zip, on which OS is it available (Mac?). If you are dealing with international transactions, it is important that the VDR is open 24/7 and supports multiple languages. Check if there is a free demo version.

Price. Most developers base their pricing based on space used and the amount of time the VDR is open. Some M&A law firms can afford to provide their own VDRs. If you need a VDR one time, use services that provide storage based on the amount of time. If you plan to use VDR regularly for a large number of transactions per year, then purchasing a subscription is your choice.


Best spreadsheet software

In this article, we will discuss the alternatives of spreadsheet software and pay attention to Zoho Sheet as the best one.

Spreadsheet software: where to use?

Spreadsheets are a powerful tool used by many professions. Spreadsheets are one of the most popular document formats used in accounting and in general in all areas where reports, cost estimates, statements, etc. are required. The ability to automate calculations by applying mathematical formulas to data placed in table cells is another reason for the popularity of this document format. However, the latter (like a number of other features) depends on the functionality of a particular program (spreadsheet processor) used to create/edit a spreadsheet.
