Sets in Python

Introduction

Sets in python are a collection of data structure which is comprised of unordered elements, unique elements, and indexed elements. All these elements are unique in their own way that means they are present one at a time only. Values belong to any type of data except index that unable the users from performing any kind of indexing operation like slicing on the index. The use of sets in python is made irrespective of the data order but what matters is that the element of data must be unique.

Sets in Python

 Operations of Python Sets

Operation of Python sets!

• Finding the length & accessing the elements
•  Adding or updating the element sets
• Removing or deleting the element sets
• Union of sets
• Intersection of sets
• Difference of sets

FINDING THE LENGTH OF A SET

Length of the set refers to the number of elements presented in the set and in order to achieve this you can make use of len(). 

ACCESSING ELEMENTS OF A SET

The elements of the set are not accessed with the help of index numbers rather they are accessed by looping through it.

ADDING ELEMENTS TO A SET

The elements are added to a set with the help of following functions;

·    The first function is added () that allow the users to add a single element to the set.

·    Second function is update() and this function is used when there is a need to add more than on element.

REMOVING ELEMENTS FROM A SET

The elements from the set are removed through following functions;

·        Remove () - This is the first function that removes the set from a specified parameter.

·       Discard() - This is used when the user is not sure whether the element is actually present in the set or not then discard() function is used.

·      Pop() – This function is particularly used when a user wants to remove the random element from the set.

UNION SETS

·        Union sets are referred to as ‘Concatenation()’ of two or more sets into a single set and this operation are practiced using two ways that are; pipeline symbol and the union method.

INTERSECTION OF SETS

·      The intersection of two or more sets forms a complete new set which is comprised of only common elements in those particular sets.

·        his is done through two ways; using ‘&’ symbol and using the ‘intersection()’.

DIFFERENCE OF SETS

·       The difference between sets produces a whole new set consisting of those elements that are present in one of those sets only.

·       This is done with the help of using ‘-‘ & using difference().

Machine Learning in Cloud-SkyWebcom

An overview of Machine Learning

Machine learning is a life-changing application and a sub-category of Artificial Intelligence (AI) that stresses upon designing the systems and allow them to learn from past experiences and make certain predictions without being openly programmed. There are three types of machine learning; Supervised, Unsupervised and Reinforced learning. Various kinds of problems can be solved by machine learning with ease like face recognition, face detection, speech recognition, object recognition and etc.

Why machine learning is used in cloud in the first place?

Why Cloud?

• While working with the system of machine learning, you’ll encounter a huge amount of data and instead of using the local infrastructure of machine learning it is better to use an online infrastructure since it has the availability of a number of machines and has hard disk capabilities as well.
• Another reason of using machine learning in the cloud is that it has instant availability of thousands of nodes or servers in a short span of time.
• The usage of cloud infrastructure in machine learning has made it easy to do the prototyping at a fast rate. If the user wants to perform with a small amount of data then it can be deployed easily & with greater speed and get a certain result. In the case of the bad distance then the procedure of prototyping will continue to process until you are provided with better results.
• The main reason of using the cloud is that machine learning lacks professionally and since there is already the availability of data in different systems of online machine learning in the cloud that does not require very highly professional data scientists and making the cloud very useful for machine learning.
• There is no requirement of any local infrastructure because there are thousands of machines that are available.

So, the above mentioned are some of the reasons for using the cloud in machine learning. Now, let’s see what are the online services are there that are made available.

Dictionary in Python

Introduction

Python dictionary is a collection of data type and it has certain features that make it very unique. Dictionary python is somewhat similar to the real world dictionary with some key-value pairs. The purpose of using a python dictionary is that it does the optimization in order to recover the values. The two main elements of the python dictionary are; Keys & Values. 

Features of Python Dictionary

1. Python dictionary is unordered that makes it possible to change the values in a dictionary.
2. It is mutable that has key value pairs as well which are similar to maps that exist in another programming languages.
3. It has index features and since the keys are different so it is easy to use it as indexes in order to access & change the values in a dictionary. 
4. Dictionary in Python has no as such duplicate members or you can say that it does not have any other replacement. 

Why a dictionary is used in Python?

Following are some of the reasons why there is a dictionary in Python.  

1. Since python, the dictionary is unordered & store the values or data like a map so it is one of the reasons that the dictionary is there in Python.
2. Unlike any other data type or object in Python, python dictionary contain the pair of key values which make it more useful.
3. The unique feature of dictionary python is that it is similar to the real world dictionary that has different types of key values in it.

Difference between Dictionary & List

• As we’ve discussed earlier dictionary Python is unordered whereas list in Python is ordered.
• Dictionary Python has access through keys whereas list in Python has access through indexes.
• Dictionary Python does the collection of key-value pairs and the list does the collection of keys.
• There are no duplicate members in Python dictionary but the list in Python does have duplicate members.
• The dictionary in Python is preferred when a user has unique key values and list in Python prefers the ordered data.

Differentiation between Propositional Logic and First Order Logic

Propositional Logic (PL)

Propositional logic is an analytical statement which is either true or false. It is basically a technique that represents the knowledge in logical & mathematical form. There are two types of propositional logic; Atomic and Compound Propositions.

Facts about Propositional Logic

Ø  Since propositional logic works on 0 and 1 thus it is also known as ‘Boolean Logic’.

Ø  Proposition logic can be either true or false it can never be both.

Ø  In this type of logic symbolic variables are used in order to represent the logic and any logic can be used for representing the variable.

Ø  It is comprised of objects, relations, functions and logical connectives.

Ø  Proposition formula which is always false is called ‘Contradiction’ whereas a proposition formula which is always true is called ‘Tautology’.

First-Order Logic (FOL)

First-Order Logic is another knowledge representation in AI which is an extended part of PL. FOL articulates the natural language statements briefly. Another name of First-Order Logic is ‘Predicate Logic’. 

Facts about First Order Logic

Ø  FOL is known as the powerful language which is used to develop the information related to objects in a very easy way.

Ø  Unlike PL, FOL assume some of the facts that are related to objects, relations and functions.

Ø  FOL has two main key features or you can say parts that are; ‘Syntax’ & ‘Semantics’.

Key differences between PL and FOL

• Propositional Logic converts a complete sentence into a symbol and makes it logical whereas in First-Order Logic relation of a particular sentence will be made that involves relations, constants, functions, and constants.
• The limitation of PL is that it does not represent any individual entities whereas FOL can easily represent the individual establishment that means if you are writing a single sentence then it can be easily represented in FOL.
• PL does not signify or express the generalization, specialization or pattern for example ‘QUANTIFIERS’ cannot be used in PL but in FOL users can easily use quantifiers as it does express the generalization, specialization, and pattern.

Introduction to AI

AI is an acronym of Artificial Intelligence which is a field of science that is in the continuous process of making machines smart. AI tries to mimic human behavior by using different kinds of algorithms. With the help of various types of algorithms, computer systems solve different kinds of problems. Artificial Intelligence has already powered search engines, recommendations of online shopping and digital assistants.

Use of AI in different fields

AI has a wide usage among different fields such as;

Ø  Radiologists use AI to calculate the exact shape & volume of tumors and gives revolutionizing treatment.

Ø  AI is also popular among astronauts where they find & evaluate the planets that are outside the solar system.

The potential of AI has no limit it can be used for fraud prevention to apply new techniques in order to deal with climate change.

Now, let’s see how AI is actually beneficial for human beings.

·        AI IN SOCIAL MEDIA

Today we all are surrounded by social media where we update literally everything and updating large amounts of data on a daily basis via chats, posts or tweets. In the case of huge amount of data, AI and machine learning are always involved. For example, in Facebook AI is used for the purpose of verification & identification of the face where machine learning & deep learning are used for detecting the facial features and also helps in tagging friends.

·         AI IN CHATBOTS

We are living in a world with highly developed technologies and one of the most used technologies with high demand is ‘Virtual Assistance’. Some of the virtual assistances are Siri, Alexa and Cortana. For example Amazon Alexa uses speech recognition and Natural Language Processing (NLP) in order to fulfill the command given by you. Virtual assistance is capable of performing number of tasks such as playing music, booking a cab or controls the devices at home.

·         AI IN HEALTHCARE

AI is also beneficial and preferable in the field of healthcare. Most of the healthcare organizations use AI to either diagnose the illness of a patient or save their lives. For example, healthcare organizations use IBM Watson (one of the AI technologies) for diagnosing the medical issues. Another example is ‘Deep Mind’ which is used in clinics to analyze the retinal scans & spot symptoms that can cause eye disease.

·         AI IN GAMING

AI is the most integral part in the field of gaming industry. AlphaGo is the first ever program of AI that beaten the professional human player, 2-Dan player named Fan Hui in October in the year of 2015 in full-sized board game.

In the coming time AI will replace human beings from doing difficult tasks that will end up reducing the workload of human beings. Learning of AI will surely help you & will lead you to different career paths and offer you with number of opportunities that you probably don’t want to miss out.
