Keywords

💡Machine Learning Model

A machine learning model is a representation of a problem that can be solved through algorithms. In the script, it is likened to a block of raw clay, which can be shaped into various forms. The model's purpose is to learn patterns from data and make predictions or decisions. It is the core component of the machine learning process, and its ability to adapt and learn from data is central to the video's theme of transformation and utility.

💡Model Training Algorithm

The model training algorithm is the process by which a machine learning model is taught to make accurate predictions. It is compared to the artist's adjustments to the clay to create a teapot. In the script, this algorithm iteratively makes small changes to the model's parameters based on the input data, aiming to minimize the difference between the model's predictions and the actual outcomes, thus 'training' the model to perform well on the task at hand.

💡Model Inference Algorithm

The model inference algorithm refers to the application of a trained model to make predictions or decisions on new, unseen data. It is depicted as the enjoyment of the teapot, signifying the practical use of the model. In the video, once the model is trained and evaluated, the inference algorithm is used to generate outputs, such as predicting the number of snow cones sold based on temperature, which exemplifies the model's real-world application.

💡Raw Clay

In the script, raw clay symbolizes the initial, untrained state of a machine learning model. It represents the potential and versatility of the model before it has been shaped by data and training algorithms. The analogy of raw clay is used to illustrate the malleability and the transformation process that the model undergoes during training.

💡Parameters

Parameters in the context of a machine learning model are the variables or coefficients that the model adjusts during training to minimize error. They are likened to the specific parts of the clay that the artist nudges to shape the teapot. In the script, the model training algorithm makes small adjustments to these parameters to improve the model's performance on the given task.

💡Linear Regression Model

A linear regression model is a statistical method for predicting a dependent variable based on one or more independent variables. In the script, it is used as an example to illustrate how a machine learning model can be applied to predict the number of snow cones sold as temperature increases, demonstrating the practical application of machine learning in real-world scenarios.

💡Data

Data is the input that a machine learning model uses to learn and make predictions. It is essential for the training process, as it shapes the model's understanding and predictions. In the script, data is compared to the raw material that the artist uses to mold the clay, emphasizing its foundational role in the creation and effectiveness of the model.

💡Prediction

Prediction in machine learning is the act of estimating an output for a given input based on the model's learned patterns. The script uses the example of predicting snow cone sales based on temperature to illustrate how a trained model can make informed forecasts, which is a key application of machine learning models.

💡Cost of Tuition

In the script, the cost of tuition is used as an example of an independent variable that can affect the dependent variable, such as the number of people attending college. This example demonstrates how machine learning models can be used to understand and predict the impact of changes in one variable on another.

💡Model Training

Model training is the process of teaching a machine learning model to make accurate predictions or decisions based on input data. It is the iterative process of adjusting the model's parameters to minimize the difference between predicted and actual outcomes. In the script, model training is compared to shaping the clay into a teapot, highlighting the gradual refinement towards the desired goal.

💡Model Inference

Model inference is the phase where a trained model is used to generate outputs for new data. It is the practical application of the trained model to solve problems or answer questions.

Transcripts

Nearly all tasks solved with machine learning involves three primary components.

The Machine Learning Model,

the Model Training Algorithm,

and the Model Inference Algorithm.

These three parts are like the different stages

after crafting a teapot from a lump of clay.

First, you will start with block of raw clay,

which represents your machine learning model.

At this stage, the clay can be modeled into

many different forms and can be used to serve many different purposes.

You decide to use this lump of clay to make a tea pot.

How do you create this teapot?

You inspect and analyze the rock clay and think about what to

change to make it look more like the teapot you have in mind.

Much like the artist who gently make

adjustment to make their clay look more and more like a teapot,

the model training algorithm makes a small changes

to the model parameters so we achieve our goals.

Now you've made your teapot.

It's been inspected, evaluated,

and now it's ready for your enjoyment.

You enjoy your teapot, drink your tea.

This represent model inference.

Now your model is ready to be used in real world.

A model is a generic program made specific by data used to train it.

Like a piece of clay,

it can be modeled into many different forms and can serve many different purposes.

A more technical definition would be that

machine learning model is a block of code or framework

that can be modified to solve different but related problems based on the data provided.

In this example, we are using a linear regression model to

predict the number of the snow cones you might expect to sell based on the temperature.

Our model here predicts that as the temperature increases,

you will sell more snow cones.

A model can also be used to predict how the number of

people who attend college changes based on the costs of admissions.

In this example our model predicts that as the cost of tuition increases,

the number of people attending college will decrease.

But how does this model do this work?

That is what model training is for.

The procedure to use data to shape a model for some use cases is called model training.

There are many model training algorithms.

To understand how they work,

let's go back to our flexible lump of clay analogy for a machine learning model.

The first thing you would do is inspect and analyze the raw clay

and think about how to change it to look more like the tea pot you have in mind.

Similarly, a model training algorithm uses the model to

process data and then compares the results against a goal.

In this step, we determine what changes need to be made to get to that goal.

Now you shape the clay to make it look more like the tea pot you have in mind.

Similarly, a model training algorithm gently nudges a specific part,

in a direction that brings the model closer to achieving their goal.

You keep doing these two steps repeatedly.

Eventually, you get closer and closer to what you

want until you determine that you're close enough to stop.

Now you have your completed teapot.

It's been inspected and evaluated.

It's ready for your enjoyment.

What does this mean from a machine learning perspective?

We are ready to use the model inference algorithm to,

for example, generate predictions using the train model.

This process is often referred to as model inference.

We just described each of these steps in a bit more detail.

Let's put it all together.

First, you start with a raw piece of clay

which can be modeled into many different things.

This represent the machine learning model.

Next, you shape your raw piece of clay to make

it look like a tea pot that you always wanted.

Similarly, the model training algorithm gently

nudges parameters to make the model capable of solving the problem.

Finally, you can enjoy your teapot and put it to work.

This represent model interference.

You use your model to solve their problem.
