Automated systems are always deterministic; whereas, autonomous systems are sometimes probabilistic.

Answer

True

Reason — Automated systems mainly use deterministic computing because they do not learn from their environment; they work on predefined rules. Probabilistic computing is more suitable for autonomous systems. Since they learn from the environment, there is some uncertainty and randomness.

The decision-making process of humans is always subjective; whereas, that of machines is always objective.

Answer

False

Reason — Human decision-making is often subjective, which means that it is affected by individual prejudices, feelings, and experiences. Machine decision-making is mainly objective, which means that it is unaffected by biases or feelings. Hence, human decision-making is not always subjective and machine decision-making is not always objective.

The classification of objects by humans and computers/machines is identical.

Answer

False

Reason — Humans classify objects based on their different attributes, like colour, shape, texture, appearance, application, etc. Humans learn all these things through experience. Machines identify objects by using machine learning algorithms and related datasets for training and testing purposes. Hence, the classification process of humans and machines is not identical.

Machine learning is a subset of artificial intelligence that enables machines to acquire knowledge without being explicitly programmed.

Answer

What distinguishes subjective decision-making from objective decision-making?

Answer

Subjective decision-making is influenced by personal feelings, emotions, experiences, beliefs, and preferences of an individual. In contrast, objective decision-making is based on facts, data, logic, and predefined rules, and is not affected by personal biases or emotions.

How do automated decision-making processes differ from human decisions?

Answer

Automated decision-making processes are based on predefined rules and programs and do not learn from the environment. They are deterministic and objective in nature. Human decision-making, on the other hand, is often subjective, influenced by emotions, experiences, and personal prejudices, and humans can adapt their decisions based on different situations.

What difficulties do autonomous system implementations present?

Answer

Autonomous system implementations present difficulties related to safety, privacy, accountability, and transparency. It is challenging to ensure that autonomous systems do not harm humans, protect personal data, clearly define responsibility when mistakes occur, and make their decision-making process understandable to humans.

What are the differences between an autonomous system and an automated system?

Answer

An automated system works on predefined rules and programs written by humans. It cannot learn from its environment and does not have decision-making capability.

An autonomous system, on the other hand, can learn from its environment, has decision-making capability, and can adapt its actions according to different situations.

How important are algorithms and programming to machine learning?

Answer

Algorithms and programming are both very important for machine learning. Programming is needed to write code that applies machine learning methods, and algorithms provide the step-by-step rules that help a machine learn patterns from data and make predictions or decisions. Hence, both are essential for machine learning.

What are the stages in machine learning?

Answer

The stages in machine learning are as follows:

1. Data collection — This is a very important step. To prepare a machine learning software, we need to collect related data.
2. Data preparation — The collected data may not be in a form to be entered directly into the algorithm. To make it compatible with the algorithm, we need to clean and transform it.
3. Selection of algorithm — There are many machine learning algorithms. We need to choose an appropriate machine learning algorithm as per our data and requirements.
4. Training — In this step, data is provided to the selected algorithm for training. By analysing and observing data, the algorithm learns its important features.
5. Evaluation — To check whether the model has learnt the features or not, we need to test it. At the time of testing, we check its accuracy and evaluate the performance of the algorithm.
6. Predict or deploy — If the testing performance of the model is good, then we can use it to make predictions.

Discuss the potential drawbacks or difficulties of using machine learning in decision-making.

Answer

The potential drawbacks or difficulties of using machine learning in decision-making are:

1. Machines are not able to learn from experience in the same way that humans do. This means that machines may not be able to make the same kind of creative and flexible decisions that humans can.
2. It is difficult to quantify human emotions and values through algorithms or programming. As a result, machine learning systems may face difficulty in making subjective decisions that involve emotions, beliefs, and personal values.

What are the different types of machine learning algorithms?

Answer

There are three main types of machine learning:

1. Supervised learning: The machine learning program is trained on a set of data that has already been labelled. By matching the names to the data, the algorithm learns to find trends in the data.
2. Unsupervised learning: The machine learning program is trained on a set of data that has not been labelled. The program learns to find patterns in the data by looking for groups of patterns that occur at the same time.
3. Reinforcement learning: In this method, an agent interacts with its surroundings and learns from trial and error. The agent takes actions, receives feedback, and adjusts its behaviour to maximise cumulative rewards.

What are the difficulties in creating autonomous systems?

Answer

The difficulties in creating autonomous systems are:

1. Safety: The system must work safely in all situations and should not harm people or property.
2. Accuracy and reliability: It should give correct results consistently, even with new or unexpected inputs.
3. Sensing and understanding the environment: Using sensors/cameras to detect objects, distance, and obstacles correctly is difficult, especially in poor light, rain, dust, etc.
4. Decision making in real time: The system must take quick and correct decisions without delay.
5. Handling unexpected situations: Real life has surprises (sudden obstacles, unusual behaviour of people/vehicles), which are hard to predict.
6. Privacy: Protecting people’s personal data collected by the system (images, location, etc.) is challenging.
7. Security: Autonomous systems can be hacked, so strong protection is required.
8. Accountability: It is difficult to decide who is responsible if the system makes a mistake—developer, company, or user.
9. Transparency: The system’s decisions should be explainable so humans can understand and trust them.
10. Cost and maintenance: Sensors, software updates, and repairs can be expensive and need regular maintenance.

Briefly describe the process of sorting fruits.

Answer

The task of sorting fruits may be considered as subjective decision-making when we are sorting fruits for personal use. In this case, the following may be the decision-making factors:

• Taste: The taste of the fruits may be the deciding factor. For example, different people like different varieties of mangoes.
• Shape or size: At the time of sorting fruits, we may be conscious of the shape of the fruit. Size is also an important factor at the time of sorting. We may prefer to collect fruits of the same size.
• Colour: Colour is also a deciding factor. For example, we only like red apples.
• Price: It would be a quantitative criterion for decision-making.

Sorting fruits involves a combination of subjective factors like personal preference as well as objective factors like quality standards and price.

How can machine learning be used to improve subjective decision making?

Answer

Machine learning can improve subjective decision-making by making it more data-driven and consistent. It helps in the following ways:

1. Finds patterns from past data: ML studies previous decisions and outcomes to learn what usually leads to better results.
2. Converts opinions into numbers: Feedback like ratings, reviews, and choices can be changed into scores, so they can be compared more objectively.
3. Reduces human bias: The same rules are applied to everyone, which can reduce favouritism and random judgement.
4. Supports better comparisons: ML can compare many factors at the same time and suggest the best option.
5. Gives predictions and recommendations: It can predict likely outcomes and recommend actions, helping decision makers choose wisely.

Thus, machine learning makes subjective decisions more fair, accurate, and based on evidence.

Which kind of data will be required for creating a machine learning model for predicting whether a student will be successful in an exam or not ?

Answer

To create a machine learning model that predicts whether a student will be successful in an exam, we need a dataset containing information about students from the past. This data helps the model learn patterns and make predictions.

The required data can include:

1. Academic Performance Data

• Marks/grades in previous tests and exams
• Subjec-wise scores and overall percentage

2. Study and Practice Data

• Hours spent studying regularly
• Homework and assignment completion
• Number of practice papers/tests attempted

3. Attendance Data

• Attendance percentage
• Regularity in attending classes

4. Classwork/Behaviour Indicators

• Class participation
• Teacher feedback on performance and effort

5. Final Result (Target Data)

• The past final exam result of the student (e.g., Pass/Fail or Successful/Not successful)
• This is the output label that the model learns to predict.
