Q – 17 Ms. Sooji is a beginner in the field of Artificial Intelligence. She got confused among the core terms like Artificial Intelligence (AI), Machine Learning (ML), and Deep Learning (DL). Many times, these terms are used interchangeably but are they the same? Justify your answer. Help her in understanding these terms by drawing a well-labeled diagram to depict the interconnection between these three fields.
Artificial Intelligence (AI) Refers to any technique that enables computers to mimic human intelligence. It gives the ability to machines to recognize a human’s face; move and manipulate objects; understand voice commands by humans, and also do other tasks. The AI-enabled machines think algorithmically and execute what they have been asked for intelligently.
Machine Learning (ML)
It is a subset of Artificial Intelligence which enables machines to improve at tasks with experience (data). The intention of Machine Learning is to enable machines to learn by themselves using the provided data and make accurate Predictions/ Decisions.
Deep Learning (DL)
It enables software to train itself to perform tasks with vast amounts of data. In Deep Learning, the machine is trained with huge amounts of data which helps it in training itself around the data. Such machines are intelligent enough to develop algorithms for themselves. Deep Learning is the most advanced form of Artificial Intelligence out of these three. Then comes Machine Learning which is intermediately intelligent and Artificial Intelligence covers all the concepts and algorithms which, in some way or the other mimic human intelligence.
There are a lot of applications of AI out of which few are those which come under ML out of which very few can be labeled as DL. Therefore, Machine Learning (ML) and Deep Learning (DL) are part of Artificial Intelligence (AI), but not everything that is Machine learning will be Deep learning.
Q – 18 What is the significance of the Al project cycle? Also, explain in detail About how Data Acquisition is different from data exploration.
Ans.: The AI Project Cycle provides us with an appropriate framework which can lead us towards the goal. The AI Project Cycle mainly has 5 stages:
1. Problem Scoping
2. Data Acquisition
3. Data Exploration
Data Acquisition: It is a process of acquiring data from various source. Data can be collected thorugh surveys, interviews, webscrapping, sensors, cameras, obersvation, and API programs. Data is collected before data collection. The data which is fed into the model is training data and prediction data is testing data.
Data Exploration: In data acquisition data which are collected may be complex. So data exploration is used to make some pattern from data or visualiza the data in a proper format. Here the data will be represeneted through various graphs and visualization forms.
Q – 19 Create a document vector table from the following documents by implementing all the four steps of Bag of words model. Also depict the outcome of each step.
Document 1 : Sameera and Sanya are classmates.
Document 2 : Sameera likes dancing but Sanya loves to study mathematics.
Step 1: Collecting data and processing it
Document 1: Sameera and Sanya are classmates
Document 2: Sameera likes dancing but Sanya loves to study mathematics
After text normalization the text becomes:
Document 1: [Sameera, and, Sanya, are , classmates]
Document 2: [Sameera, likes, dancing, but, Sanya, loves, to, study , mathematics]
Step 2: Create a Dictionary
Step 3 : Create a Document Vector
Step 4: Repeat for all documents
Q – 20 Will it be valid to say that not all the devices which are termed as smart are Al-enabled? Justify this statement. Explain any two examples from daily life which are commonly misunderstood as Al.
Ans.: No, not all the devices which are termed as Smart are AI enables. any machine that has been trained with data and can make decisions/predictions on its own can be termed as AI. Here, the term ‘training’ is important.
A fully automatic washing machine can work on its own, but it requires human intervention to select the parameters of washing and to do the necessary preparation for it to function correctly before each wash, which makes it an example of automation, not AI.
An air conditioner can be turned on and off remotely with the help of internet but still needs a human touch. This is an example of Internet of Things (IoT). Also, every now and then we get to know about robots which might follow a path or maybe can avoid obstacles but need to be primed accordingly each time.
Just as humans learn how to walk and then improve this skill with the help of their experiences, an AI machine too gets trained first on the training data and then optimises itself according to its own experiences which makes AI different from any other technological device/machine.
Q – 21 Recently the country was shaken up by a series of earthquakes which has done a huge damage to the people as well as the infrastructure. To address this issue, an Al model has been created which can predict if there is a chance of earthquake or not. The confusion matrix for the same is :
(i) There are 20 Negative cases in the above scenario.
(ii) To calculate precision we need True Positive cases and All predicted positives. So
True Positive – 50
False Positive – 05
precision = TP/(TP+FP)*100%=50/(50+5)*100%=50/55*100%=0.91
For recall, we need True Positive and False Negative which are 50 and 25.
F1 score= 2*((precision*recall)/(precision+recall))=2*((0.91*06.7)/(0.91+0.67))=2*(0.6097/1.58)=2*0.386=0.772
