Video Title: Machine Learning Tutorial Python -1: What is Machine Learning?
I’m happy to announce new series on machine learning with Python in this tutorial. We are going to look into what is machine learning There are certain tasks where computers are really better than humans For example, if I ask you to multiply these two big numbers you will take lot of time
Whereas computers can do it in less than a second similarly if I ask you to search through millions of Records then that search operation is extremely difficult for humans whereas machines can Do it in a matter of nano second on
The other hand there are some tasks where humans outperform machines such as driving the car You don’t see many robots driving the car on the road today In Bay Area a Google and uber and Tesla These companies are trying or travel less cars, but it is still in initial phase as of 2018
So most of the cars driven on the road are still by humans Natural language conversation is also an area where humans outperform machines So machine learning tries to make computers better at things where traditionally humans were outperforming machines and the way we do that is We make machines learn things like humans do
So the question is Why humans are better in driving the cars and having a conversation? For that we need to understand how human brain works human brain consists of tiny neurons there are billions of neurons in our brain and Whenever we think or make a decision a
Signal a chemical signal is generated and these a tiny neurons light up here is a simple model of these neurons where these rounds are the neurons and the arrows are the synapses that Connect these neurons So what happens is? let’s say when you have a baby and baby sees a
Cow for the first time You will tell baby that this is a cow so internal in her brain Specific set of neurons will light up and these two output neurons each corresponds to a specific entity such as cow and a car When you say that, this is a cow
This set of neurons are lighting up and the edges they become stronger These edges are shown in yellow in a blue dark color here and it leads to a certain output This is like you’re you are in a jungle and you are looking for a direction
Now you found a direction to reach to a specific destination Next day when baby sees a second cow you will tell the baby that ok This is also a cow. So again same set of neurons and some additional neurons light up and these pathways become more stronger
Similarly when a baby is seeing a car you will tell her that this is a car and Some other set of neurons will light up the ages will become stronger and so forth This way you are training a baby. Ok
So as a human we all know in our childhood the way we learn things are We make mistakes someone corrects the mistakes and then we learn During the learning procedure what happens in our brain is Constantly these ages and neurons are being adjusted and these new pathways are being created
That leads to a certain output or a decision computers can also be trained in similar way where neural network models are created and they are trained with a lot of training data and the corresponding output and these neurons and these ages are adjusted and
The neural network becomes trained so that later on when you give a new input to machine It can tell you the correct output This is called deep learning and deep learning is one of the areas Machine learning machine learning is a quite a broader term
It is a complete a science of field in computer science where we use various techniques and deep learning is one of them there are other techniques where we use The knowledge present in available data, we extract it and use that knowledge to make our future decisions
So overall as I said before machine learning is a bigger area deep learning is one part of it and There are like mathematical and statistical models that we use To make predictions so that’s another area Machine learning has a big implication on our real life
One of the important features in any email account is spam filter if you are using Google or Yahoo Or any other email account you will see that They filter the spam emails automatically The way they do it is they have seen a lot of spam
Emails in the past and they train machines to learn from the content of those emails and they filter it out for future personal assistant type of devices such as Amazon Alexa and Google home is another example they are getting increasingly better at human conversation when you talk to them they
Learn your lesson. They learn your terminology and then in the future they Give you an accurate reply for the question that you asked them Youtube’s recommended video is another example of machine learning where they look at your past pattern on
What kind of content you’re watching and based on that they will generate the suggestions Last but not least is driverless cars. I wouldn’t be surprised if in next 10 years you will see many tireless cars on the roads because
Companies like Tesla Google uber they’re investing heavily in driverless cars and all of them are using Machine learning and artificial intelligence techniques are to make cars Martyr So that’s all I had for this introduction tutorial The next tutorial we are going to write some Python code to make some predictions using linear regression
Thanks for watching. Bye

Hi, I had trouble because my Python was installed in a different path from Anaconda path. If I downloaded any package for Machine Learning, it would show that it is not installed. I tried everything from pip install to conda install, command line, installation from the notebook itself, etc, but nothing would work. So, I uninstalled both Python and Anaconda for a fresh start. Do you have any recommendations for the next time when I install Python and Anaconda?
Thanks.
far better than CourseEra IBM course
great topic thanks 👍
👍
sir , make a video about parameters used in Machine Learning and explain each parameters and its usage
and same to Deep learning also. sir please its a humble request .tq
Please I have a question, so I need to know data science before learning machine learning
https://www.youtube.com/watch?v=-lpiVh02Y54&t=58s
Sir, can you make video for image processing? Thank you
On the exercise data my model score is only 81% , can I improve it more ?
I considered Dependent varaibles only the column you showed in the video
in just 5 years tesla has been market leader for driverless and EV cars, ML is really interesting
Is this beneficial in 2023?
hi, i have a doubt , currently i am working as a flutter developer , i am planning to learn machine learning , is it necessary to learn SQL and Data structure to become machine learning engineer
Reply
Hi sir could you please send reference videos related to crop prediction system through ML
is it still worth doing in 2023?
Your videos are very easy to understand.
The answer to the math problem you brought up at the beginning is 2.4017842426e+23
nice
Hi sir,
I did random forest model but I got low f1 score so I have dropped three features after feature importance .
But I got xtrain and xtest is different columns. How to resolve? Could you please help?
Ytrain has different rows than xtrain
sir, your course is simply wonderful. you made a great job to give us search quality material. really thank you very much!!!
Thank you very much
THANSK SIR
What an explanation…. Unbelievable😍👍 👌👌
Need a study partner.. Anyone from neuroscience background?
Hi Sir, I want to build my career in AI. Could you please tell me how I start my career in this field I don't have any idea about it? Do I need to do an MBA for it? Now I am working in an IT company. In 2021 I completed my graduation in computer science engineering. Please clarify my doubts asap. Thank You.

excellent
Hi sir, Good Evening.. I am planning to study Data science & Analytics in UK.
In 2023 Jan intake.. Is UK good to study Data Science course.
Simply Amazing ! Keep sharing the knowledge 🙂
Sir! reg.predict(3300) shows error, doesn't execute
for anomaly detection -which algorithm is used for superwised learning method used
