Answered: _____ is not a Learning-based Approach where the AI model gets trained on the data fed to it and then is able to design a model which is adaptive to the change in data.

Wed, 12 Mar 2025 02:12:53 +0000

(d) Enforcement Learning

Explanation

Supervised Learning: This is a learning-based approach where the AI model is trained on a labeled dataset. The model learns to map inputs to outputs based on those labels and can adapt as it sees more data.
Unsupervised Learning: In this approach, the model finds patterns or structures in data that is not labeled. It also qualifies as a learning-based method since the model adapts based on the data’s inherent structure.
Reinforcement Learning: This is another learning-based approach where the model learns by interacting with an environment and receiving rewards or punishments. Over time, it adapts its behavior to maximize rewards.
Enforcement Learning: Unlike the above, "Enforcement Learning" is not a recognized method in the AI or machine learning domain. It is likely a distractor in this question. As such, it does not represent a valid learning-based approach where the model adapts based on data or feedback.

Thus, Enforcement Learning is the one that is not a learning-based approach.

1. The problem can be identified and goals can be set

Answered: Give an example where High Accuracy is not usable.

Fri, 08 Mar 2024 12:31:23 +0000

Let us go back to the Forest Fire example. Assume that the model always predicts that there is no fire.

But in reality, there is a 2% chance of forest fire breaking out. In this case, for 98 cases, the model will be right but for those 2 cases in which there was a forest fire, then too the model predicted no fire.

Here,

True Positives = 0
True Negatives = 98
Total cases = 100
Therefore, accuracy becomes: (98 + 0) / 100 = 98%

This is a fairly high accuracy for an AI model.

But this parameter is useless for us as the actual cases where the fire broke out are not taken into account.

Hence, there is a need to look at another parameter which takes account of such cases as well known as precision.

Supervised Learning	Unsupervised Learning
Supervised learning is where a computer algorithm is trained on input data that has been labeled for a particular output. Classification and Regression models are also types of supervised learning.	In terms of machine learning, unsupervised learning is in which a system learns through data sets created on its own. In this, the training is not labeled. It is divided into clustering and dimensionality reduction.
For example- A shape with three sides is labeled as a triangle.	Learning on its own is termed Unsupervised learning

Sun, 26 Feb 2023 02:37:34 +0000

Document Vector contains the frequency of each word of the vocabulary in a particular document.

In document, vector vocabulary is written in the top row. Now, for each word in the document, if it matches with the vocabulary, put a 1 under it. If the same word appears again, increment the previous value by 1. And if the word does not occur in that document, put a 0 under it.

Document Vector Table is used while implementing the Bag of Words algorithm. In a document vector table, the header row contains the vocabulary of the corpus and other rows correspond to different documents. If the document contains a particular word it is represented by 1 and the absence of a word is represented by 0 value.

Document Vector Table is a table containing the frequency of each word of the vocabulary in each document.

Answer edited: Differentiate between Human Language and Computer Language

Thu, 02 Feb 2023 12:45:02 +0000

Humans communicate through language which we process all the time. Our brain keeps on processing the sounds that it hears around itself and tries to make sense out of them all the time.

On the other hand, the computer understands the language of numbers. Everything that is sent to the machine has to be converted to numbers.

And while typing, if a single mistake is made, the computer throws an error and does not process that part. The communications made by the machines are very basic and simple.

Here is a more detailed comparison table between Human Language and Computer Language:

Human Language	Computer Language
Natural	Synthetic
Ambiguous	Precise
Context-dependent	Context-independent
Dynamic	Static
Evolving	Fixed
Verbose	Concise
Uses grammar and syntax rules	Uses strict syntax and semantic rules
Varies by culture and region	Universal
Used for communication between humans	Used for communication between computers and humans
Can have different interpretations	Has a set of predefined instructions that produce specific outputs

Human languages are natural and used for communication between people, often varying by culture and region. They can be ambiguous and context-dependent, and are dynamic, changing over time.

Computer languages, on the other hand, are synthetic and used for communication between computers and humans.

They are precise and strict, using strict syntax and semantic rules to ensure the computer accurately understands the instructions.

They are also context-independent, meaning the same instruction will produce the same result no matter the context.

Computer languages are concise, using specific keywords and syntax to produce specific outputs.

Thu, 12 Jan 2023 14:04:40 +0000

The 4W Canvas is a framework that helps to break down a problem into its key components. Here's an example of how it can be applied to the problem of pollution:

What: Pollution is the presence or introduction into the environment of a substance or thing that has harmful or poisonous effects.

Who: Pollution affects everyone, but it disproportionately affects marginalized communities, low-income individuals, and people living in urban areas. It also affects different species of animals and plants.

Where: Pollution can occur in any environment, including air, water, soil, and the built environment. It can also happen in both urban and rural areas.

Why: Pollution is caused by human activities such as industrial processes, transportation, and energy production. It also results from natural events like volcanic eruptions and wildfires.

How: To address pollution, we can take actions such as:

Reducing our use of fossil fuels
Encouraging the use of renewable energy sources
Improving public transportation
Implementing regulations and laws to limit the amount of pollution that businesses and industries can produce
Promoting recycling and waste reduction
Educating the public about pollution and how to reduce their impact.

This 4W Canvas is a framework to look at the problem of pollution, and it can help to identify the main components of the problem and potential solutions.

Answer edited: What is evaluation ? Class 10 CBSE

Mon, 13 Jun 2022 12:06:58 +0000

Evaluation is the process of understanding the reliability of any AI model, based on outputs by feeding the test dataset into the model and comparing it with actual answers.
There can be different Evaluation techniques, depending on the type and purpose of the model.
Remember that It’s not recommended to use the data we used to build the model to evaluate it.
This is because our model will simply remember the whole training set, and will therefore always predict the correct label for any point in the training set. This is known as overfitting.

Evaluation is the Last Stage of the AI Project Cycle, All the Stages are Listed Below:-

Problem Scoping - Understanding the problem
Data Acquisition - Collecting accurate and reliable data
Data Exploration - Arranging the data uniformly
Modelling - Creating Models from the data
Evaluation - Evaluating the project
