JOURNEY BEGINS

Welcome to the blog of Errolee Gerie.✋✋

Media literary

eye color changing was the first activity that we have done in this course.

                    Binary code 

 We learn how to convert any number into binary code which is the language of our DEAR computer. The short video below will show you how we covert: 

​

hope you enjoy the video and that it was useful

​as a reminder, we decide by 2 because binary starts with bi=2.

Moreover, I know you all want a realistic picture without spending hours on taking the RIGHT PICTURES with the RIGHT ANGLE. I got guys to watch that youtube video and I promise you will spend fewer hours editing.

we used AUDACITY as it provides many functions and it was easy to merge audio. we could have used cam studio but it has the following pros:

• CamStudio at this time only supports Windows and has very little in the way of editing capabilities unless you can install some of the user-made extensions.
• With no base editing capabilities, the software is really stripped down when compared to some of the competitors and it cannot directly record for mobile devices without a patch.
• It's also not a great program for game recording and it only offers output formatting SWF and AVI.
• The official website has also had some problems with security from individuals downloading software extensions infected with Trojan viruses.

Hi, today I am we will talk about online Presence. what is Online Presence? well, it is simply your interactions with others online like your Facebook profile or your Instagram in the professional era it will linkdin .your profile say a lot about you so try to say something or share nicely as everything your post will ALWAYS BE remembered. 

We also discuss our first presentation on how small businesses use social media right. We also discuss branding like the MADE IN MORIS which reflects the country's multicultural that exists. hence, branding is important as it will be the first thing that will represent the country and therefore picture the right things.

we have our first presentation on how small businesses have used social media in the right way to promote their business. 

the business chosen is optimal.com a shoe-running company.

Virtual Reality (VR) is defined as a computer-generated environment with scenes and objects that appear to be real, making the user feel they are immersed in their surroundings. This environment is perceived through a device known as a Virtual Reality headset or helmet. 

Today we learn about the virtual world. we live in a world where digital is widely used when I was a kid I used to play a game called SIMS without knowing it was a virtual world.

virtual tour

A virtual tour is the simulation of an existing location with the help of sequential videos or still images. Other multimedia elements like music, sound effects, floor plans, etc., could also be used. They help in recreating a realistic representation of reality. Virtual tours help in presenting views of inaccessible areas and provide an interesting and excellent alternative to fieldwork when expenses, time, or logistics are an issue for people.

let's take a virtual cave as an example

Virtual cave 

A VR CAVE (Cave Automatic Virtual Environment) is a VR space or cube-like room, with 3D images projected onto the walls of the room, to create a walk-in immersive 3D environment. The options of a VR CAVE are numerous, such as projectors, tracking, number of screens, size of screens, and resolutions, and, likely, no two cases are alike. 

Why use a VR CAVE? 

More and more companies are looking at a CAVE system VR when they want to be able to bring several people into a single virtual experience. The ability to have up to 10 people all watching the same image, with one person acting as leader or guide through the virtual experience makes it great for a group, especially in a presentation-type scenario. As well as having people in front of the screen, several remotely located CAVE virtual reality systems can be connected together to provide a collaborative experience, even adding in remote users with Head Mounted Displays (HMDs) as avatars on the screen.

The CAVE setup has the advantage over an HMD solution in that all the viewers can see the 3D images, whilst wearing 3D glasses, they o can be fully immersed, rather than watching a 2D screen whilst one person is using an HMD. Another element of a VR CAVE setup is the possibility to go further by enhancing the virtual environment with real-world input devices to increase the 3D immersion effect by having tactile interactions. Devices such as a haptic arm can be added for learning gestures, accessibility control or ergonomics studies, or a physical control panel that moves objects within the virtual scene.

Does the CAVE automatic virtual environment have limits? 

There can be many obstacles to the adoption of the VR CAVE, starting with the cost of installation. This type of immersive 3D installation costs around €80,000 for a 2-sided corner cave and up to €750,000 for a 6-sided CAVE, plus the maintenance and usage costs that can amount to more than €3,000 per month.

The space required is also a vital consideration in the installation of a CAVE virtual environment. It is imperative to have a relatively spacious room to accommodate all the needed hardware (the TORE project illustrates this well), and the necessary space for the installation of projectors (which is less in the case for LED screens or when using mirrors), plus items such as the air conditioning system, lighting, control desk, etc.

The installation of a virtual reality CAVE also has several factors to consider to ensure optimum performance, for example, a strong vibration close to the cave automatic virtual environment can shift the projectors and force a resynchronization or an external light source can interfere with the tracking.

In that virtual world what we see often is an avatar as we(people) cannot be projected in that world hence as classwork we have to create our own avatar

Virtual chat box

Chatbots are virtual advisors, consultants, or assistants whose task is to talk to an Internet user in real time. However, they conduct conversations without human intervention. In reality, they are computer programs equipped with unique algorithms that enable discussion and activities related to your customer's needs.

Augmented reality

 With augmented reality, we can augment the past with the present. let me ask we all want to attend the concert of the KING OF POP and feel that sensation that our parents felt but how?. that is when augmented reality came into action.

 It will allow us to view the world in our way like looking at the sky and seeing the moonwalk of the great MICHEAL JACKSON.

Here is an example of how we can augment our real world.

we can listen to a song and view it can the same as if it is happening in front of our eyes.

we use the app Halo AR to augment and we try it and it turns out to be nice here are some examples:

Moreover, with AR we can teach people that why my project on AR will be on a mountain as listed below:

Hence, we can create something that might not exist in the real world but the sensation will make it feel as if it's real thus let's watch that short story video about my new invention.

hope that the invention will help students in their studies

pros and cons virtual world.

Pros	Cons
Better than reality	High cost
Used in various fields	Communication should not be replaced by a group of people
Users have awesome experiences	Feeling of worthlessness
Gives detail views	Users addicted to the virtual world
Connects with people	Technology is still experimental
Effective communication	Training in a VR environment is not real

After the virtual world let's come back to reality.

we learn about employability

what is student employability?

well, we cannot go into the working world without having some skills hence we need to develop. Therefore, we have to develop skills that employers want. As we all know our employers want us to have good communication skills 

In an organization, we have different levels which explain the levels of how work is being done and how each level views something specific.

Test day, Recommender systems and input-output

Recommender Systems

A recommender system, or a recommendation system, is a subclass of information filtering system that seeks to predict the “rating” or “preference” a user would give to an item. They are primarily used in commercial applications

Examples of Recommender Systems:

Netflix, YouTube, Tinder, and Amazon . 

The systems entice users with relevant suggestions based on the choices they make. Recommender systems can also enhance experiences for: News Websites.

Types of Recommender Systems

Recommender systems are typically classified into the following categories:

• Content-based filtering
• Collaborative filtering
• Hybrid systems

Depending on whether a model is learned from the underlying data, recommender system can be divided into:

• Memory-based
• Model-base

The test was on collaborative filtering and content-based filtering

collaborative filtering 

collaborative filtering uses similarities between users and items simultaneously to provide recommendations. collaborative filtering models can recommend an item to user A based on the interests of a similar user B. Furthermore, the embeddings can be learned automatically, without relying on hand-engineering of features.

A Movie Recommendation Example

Consider a movie recommendation system in which the training data consists of a feedback matrix in which:

• Each row represents a user.
• Each column represents an item (a movie).

The feedback about movies falls into one of two categories:

• Explicit— users specify how much they liked a particular movie by providing a numerical rating.
• Implicit— if a user watches a movie, the system infers that the user is interested.

To simplify, we will assume that the feedback matrix is binary; that is, a value of 1 indicates interest in the movie.

When a user visits the homepage, the system should recommend movies based on both:

• similarity to movies the user has liked in the past
• movies that similar users liked

Advantages

No domain knowledge necessary

We don't need domain knowledge because the embeddings are automatically learned.

Serendipity

The model can help users discover new interests. In isolation, the ML system may not know the user is interested in a given item, but the model might still recommend it because similar users are interested in that item.

Great starting point

To some extent, the system needs only the feedback matrix to train a matrix factorization model. In particular, the system doesn't need contextual features. In practice, this can be used as one of multiple candidate generators.

Disadvantages

Cannot handle fresh items

The prediction of the model for a given (user, item) pair is the dot product of the corresponding embeddings. So, if an item is not seen during training, the system can't create an embedding for it and can't query the model with this item.

Hard to include side features for query/item

Side features are any features beyond the query or item ID. For movie recommendations, the side features might include country or age. Including available side features improves the quality of the model. Although it may not be easy to include side features in WALS, a generalization of WALS makes this possible.

Content-based Filtering

Content-based filtering uses item features to recommend other items similar to what the user likes, based on their previous actions or explicit feedback.

You also represent the user in the same feature space. Some of the user-related features could be explicitly provided by the user. For example, a user selects "Entertainment apps" in their profile. Other features can be implicit, based on the apps they have previously installed. For example, the user installed another app published by Science R Us.

The model should recommend items relevant to this user. To do so, you must first pick a similarity metric (for example, dot product). Then, you must set up the system to score each candidate item according to this similarity metric. Note that the recommendations are specific to this user, as the model did not use any information about other users.

Content-based Filtering Advantages & Disadvantages

Advantages

• The model doesn't need any data about other users, since the recommendations are specific to this user. This makes it easier to scale to a large number of users.
• The model can capture the specific interests of a user, and can recommend niche items that very few other users are interested in.

Disadvantages

• Since the feature representation of the items are hand-engineered to some extent, this technique requires a lot of domain knowledge. Therefore, the model can only be as good as the hand-engineered features.
• The model can only make recommendations based on existing interests of the user. In other words, the model has limited ability to expand on the users' existing interests.
  

Input and output

An input/output device, often known as an IO device, is any hardware that allows a human operator or other systems to interface with a computer. Input/output devices, as the name implies, are capable of delivering data (output) to and receiving data from a computer (input).

example of input and output devices:

input/Output StreamsI/O: sequence of bytes (stream of bytes) from source to destinationBytes are usually characters, unless program requires other types of informationStream: sequence of characters from source to destinationInput Stream: sequence of characters from an input device to the computerOutput Stream: sequence of characters from the computer to an output device

information source and destination

the Source is a particular location and the Destination is a different location.

Smart system and sensors

What is Smart System

1.

A system incorporating sensing actuation and control in order to make decisions based on the available data. 

2.

A smart system incorporates ICT functionality into ‘traditional’ technologies, thus providing them with advanced control and amenability functions. 

3.

Smart systems combine sensing, actuation, and control capabilities to describe and analyze a condition, make decisions that are predictive or adaptive, and take smart actions as a result. Most of the time, the autonomous operation based on closed loop control, energy efficiency, and networking capabilities can be used to explain the system's “smartness.” 

What is a smart sensor?

A smart sensor is a device that takes input from the physical environment and uses built-in compute resources to perform predefined functions upon detection of specific input and then process data before passing it on.

Smart sensors enable more accurate and automated collection of environmental data with less erroneous noise amongst the accurately recorded information. These devices are used for monitoring and control mechanisms in a wide variety of environments including smart grids, battlefield reconnaissance, exploration and many science applications.

The smart sensor is also a crucial and integral element in the internet of things (IoT), the increasingly prevalent environment in which almost anything imaginable can be outfitted with a unique identifier and the ability to transmit data over the internet or a similar network. One implementation of smart sensors is as components of a wireless sensor and actuator network (WSAN) whose nodes can number in the thousands, each of which is connected with one or more other sensors and sensor hubs, as well as individual actuators.

Compute resources are typically provided by low-power mobile microprocessors. At a minimum, a smart sensor is made of a sensor, a microprocessor and communication technology of some kind. The compute resources must be an integral part of the physical design -- a sensor that just sends its data along for remote processing isn't considered a smart sensor.

How do smart sensors work?

A smart sensor ties a raw base sensor to integrated computing resources that enable the sensor's input to be processed.

The base sensor is the component that provides the sensing capability. It might be designed to sense heat, light or pressure. Often, the base sensor will produce an analog signal that must be processed before it can be used. This is where an intelligent sensor's integrated technology comes into play. The onboard microprocessor filters out signal noise and converts the sensor's signal into a usable, digital format.

ethics in technology

We utilize our own ethical standards for technology as a set of rules to direct our choices and actions when utilizing it. It incorporates values like privacy observance, data security, and prudent technology usage to safeguard the rights and interests of people and organizations. To ensure that technology does not negatively affect society or the environment, it also necessitates that we utilize it with awareness

why ethics and technology 

• ethical guidelines are a set of principles or rules that help individuals or organizations make decisions in a morally responsible and fair manner. They serve as a roadmap for behavior and decision-making, helping to ensure that people act in accordance with their values and obligations. Some common ethical guidelines include: 
• Honesty: Being truthful and transparent in all dealings and interactions. 
• Respect: Treating others with dignity and courtesy, regardless of their background or beliefs. 
• Responsibility: Being accountable for one's actions and decisions and taking ownership of the consequences that arise from them. 
• Fairness: Treating others equally and without bias and avoiding any actions that would be seen as discriminatory or unjust. 
• Confidentiality: Protecting sensitive information and respecting the privacy of others. 
• Professionalism: Maintaining high standards of competence, skill, and integrity in one's work. 
• Sustainability: Ensuring that actions and decisions consider their impact on the environment and future generations. 
• These ethical guidelines can be found in many different settings, including businesses, professions, and organizations, and they help to promote integrity, trust, and social responsibility.
