Artificial intelligence doesn't make us dumber, it makes us smarter. It presents us with the challenge of asking the right questions. Artificial intelligence doesn't know what we want and that's why it's so incredibly important to develop a specific question for a specific request and that's often harder than you think.

You have to think carefully about what you need to ask the right question that is specific and then use the answer provided by artificial intelligence to solve your problem. This requires a lot of thought, and artificial intelligence helps us to formulate our concerns more precisely and apply the outputs specifically. Using artificial intelligence well and correctly is not a trivial task, but requires some effort.

Three different learning styles in machine learning algorithms:

1. Supervised Learning

Input data is called training data and has a known label or result such as spam/not-spam or a stock price at a time.

A model is prepared through a training process in which it is required to make predictions and is corrected when those predictions are wrong. The training process continues until the model achieves a desired level of accuracy on the training data.

Example problems are classification and regression.

Example algorithms include: Logistic Regression and the Back Propagation Neural Network.

2. Unsupervised Learning

Input data is not labeled and does not have a known result.

A model is prepared by deducing structures present in the input data. This may be to extract general rules. It may be through a mathematical process to systematically reduce redundancy, or it may be to organize data by similarity.

Example problems are clustering, dimensionality reduction and association rule learning.

Example algorithms include: the Apriori algorithm and K-Means.

3. Semi-Supervised Learning

Input data is a mixture of labeled and unlabelled examples.

There is a desired prediction problem but the model must learn the structures to organize the data as well as make predictions.

Example problems are classification and regression.

Example algorithms are extensions to other flexible methods that make assumptions about how to model the unlabeled data.

How do you start AI and ML ?

Where do you go to learn these skills? What courses are the best?

There’s no best answer🥺. Everyone’s path will be different. Some people learn better with books, others learn better through videos.

What’s more important than how you start is why you start.

Start with why.

Why do you want to learn these skills?
Do you want to make money?
Do you want to build things?
Do you want to make a difference?
Again, no right reason. All are valid in their own way.

Start with why because having a why is more important than how. Having a why means when it gets hard and it will get hard, you’ve got something to turn to. Something to remind you why you started.

Got a why? Good. Time for some hard skills.

I can only recommend what I’ve tried every week new course lauch better than others its difficult to recommend any course

You can completed courses from (in order):

Treehouse / youtube( free) - Introduction to Python

Udacity - Deep Learning & AI Nanodegree

fast.ai - Part 1and Part 2

They’re all world class. I’m a visual learner. I learn better seeing things being done/explained to me on. So all of these courses reflect that.

If you’re an absolute beginner, start with some introductory Python courses and when you’re a bit more confident, move into data science, machine learning and AI.

Today, lets understand Machine Learning in simplest way possible

What is Machine Learning?

Think of it like this:

Machine Learning is when you teach a computer to learn from data, so it can make decisions or predictions without being told exactly what to do step-by-step.

Real-Life Example:
Let’s say you want to teach a kid how to recognize a dog.
You show the kid a bunch of pictures of dogs.

The kid starts noticing patterns — “Oh, they have four legs, fur, floppy ears...”

Next time the kid sees a new picture, they might say, “That’s a dog!” — even if they’ve never seen that exact dog before.

That’s what machine learning does — but instead of a kid, it's a computer.

In Tech Terms (Still Simple):

You give the computer data (like pictures, numbers, or text).
You give it examples of the right answers (like “this is a dog”, “this is not a dog”).
It learns the patterns.

Later, when you give it new data, it makes a smart guess.

Few Common Uses of ML You See Every Day:

Netflix: Suggesting shows you might like.
Google Maps: Predicting traffic.
Amazon: Recommending products.
Banks: Detecting fraud in transactions.

Stanford packed 1.5 hours with everything you need to know about LLMs

Here are 5 lessons that stood out from the lecture:

1/ Architecture ≠ Everything
→ Transformers aren’t the bottleneck anymore.
→ In practice, data quality, evaluation design, and system efficiency drive real gains.

2/ Tokenizers Are Underrated
→ A single tokenization choice can break performance on math, code, or logic.
→ Most models can't generalize numerically because 327 might be one token, while 328 is split.

3/ Scaling Laws Guide Everything
→ More data + bigger models = better loss. But it's predictable.
→ You can estimate how much performance you’ll gain before you even train.

4/ Post-training = The Real Upgrade
→ SFT teaches the model how to behave like an assistant.
→ RLHF and DPO tune what it says and how it says it.

5/ Training is 90% Logistics
→ The web is dirty. Deduplication, PII filtering, and domain weighting are massive jobs.
→ Good data isn’t scraped, it’s curated, reweighted, and post-processed for weeks.

Neural Networks and Deep Learning
Neural networks and deep learning are integral parts of artificial intelligence (AI) and machine learning (ML). Here's an overview:

1.Neural Networks: Neural networks are computational models inspired by the human brain's structure and functioning. They consist of interconnected nodes (neurons) organized in layers: input layer, hidden layers, and output layer.

Each neuron receives input, processes it through an activation function, and passes the output to the next layer. Neurons in subsequent layers perform more complex computations based on previous layers' outputs.

Neural networks learn by adjusting weights and biases associated with connections between neurons through a process called training. This is typically done using optimization techniques like gradient descent and backpropagation.

2.Deep Learning : Deep learning is a subset of ML that uses neural networks with multiple layers (hence the term "deep"), allowing them to learn hierarchical representations of data.

These networks can automatically discover patterns, features, and representations in raw data, making them powerful for tasks like image recognition, natural language processing (NLP), speech recognition, and more.

Deep learning architectures such as Convolutional Neural Networks (CNNs), Recurrent Neural Networks (RNNs), Long Short-Term Memory networks (LSTMs), and Transformer models have demonstrated exceptional performance in various domains.

3.Applications Computer Vision: Object detection, image classification, facial recognition, etc., leveraging CNNs.

Natural Language Processing (NLP) Language translation, sentiment analysis, chatbots, etc., utilizing RNNs, LSTMs, and Transformers.
Speech Recognition: Speech-to-text systems using deep neural networks.

4.Challenges and Advancements: Training deep neural networks often requires large amounts of data and computational resources. Techniques like transfer learning, regularization, and optimization algorithms aim to address these challenges.

LAdvancements in hardware (GPUs, TPUs), algorithms (improved architectures like GANs - Generative Adversarial Networks), and techniques (attention mechanisms) have significantly contributed to the success of deep learning.

5. Frameworks and Libraries: There are various open-source libraries and frameworks (TensorFlow, PyTorch, Keras, etc.) that provide tools and APIs for building, training, and deploying neural networks and deep learning models.

You won’t become an AI Engineer in a month.

You won’t suddenly build world-class systems after a bootcamp.

You won’t unlock next-level skills just by binge-watching tutorials for 30 days.

Because in a month, you’ll realize:

— Most of your blockers aren’t about “AI”, they’re about solid engineering: writing clean code, debugging, and shipping reliable software.

— Learning a new tool is easy; building things that don’t break under pressure is where people struggle.

— Progress comes from showing up every day, not burning out in a week.
So what should you actually do?

Here’s what works:

→ Spend 30 minutes daily on a core software skill.
One day, refactor old code for readability. Next, write unit tests. After that, dive into error handling or learn how to set up a new deployment pipeline.

→ Block out 3–4 hours every weekend to build something real.
Create a simple REST API. Automate a repetitive task. Try deploying a toy app to the cloud.
Don’t worry about perfection. Focus on finishing.

→ Each week, pick one engineering topic to dig into.
Maybe it’s version control, maybe it’s CI/CD, maybe it’s understanding how authentication actually works.

The goal: get comfortable with the “plumbing” that real software runs on.

You don’t need to cram.
You need to compound.
A little progress, done daily

That’s how you build confidence.
That’s how you get job-ready.

Small efforts. Done consistently.

That’s the unfair advantage you’re waiting to find, always has been.
