Go to comments # [New Release] Machine Learning and AI: Support Vector Machines in Python January 22, 2019 ### Support Vector Machines in Python Wow, I didn’t think I’d be coming out with another course so soon – but here it is! [if you don’t want to read my little spiel just click here to get your VIP coupon: https://deeplearningcourses.com/c/support-vector-machines-in-python] [By the way, I went all-out this time in the VIP version – you’ll want to check it out below – comes with 4 all-new models (both theory+code provided of course)] SVMs are one of the most robust and powerful machine learning models. It can be a very useful “plug-and-play” solution – just throw your data in the model and wait for the magic to happen. Unlike deep learning, where you can spend days or weeks tuning your hyperparameters, SVMs only have 2 hyperparameters, which are generally easy to understand and reason about. One of the things you’ll learn about in this course is that a support vector machine actually is a neural network, and they essentially look identical if you were to draw a diagram. The toughest obstacle to overcome when you’re learning about support vector machines is that they are very theoretical. This theory very easily scares a lot of people away, and it might feel like learning about support vector machines is beyond your ability. Not so! In this course, we take a very methodical, step-by-step approach to build up all the theory you need to understand how the SVM really works. We are going to use Logistic Regression as our starting point, which is one of the very first things you learn about as a student of machine learning. So if you want to understand this course, just have a good intuition about Logistic Regression, and by extension have a good understanding of the geometry of lines, planes, and hyperplanes. This course will cover the critical theory behind SVMs: • Linear SVM derivation • Hinge loss (and its relation to the Cross-Entropy loss) • Quadratic programming (and Linear programming review) • Slack variables • Lagrangian Duality • Kernel SVM (nonlinear SVM) • Polynomial Kernels, Gaussian Kernels, Sigmoid Kernels, and String Kernels • Learn how to achieve an infinite-dimensional feature expansion • Projected Gradient Descent • SMO (Sequential Minimal Optimization) • RBF Networks (Radial Basis Function Neural Networks) • Support Vector Regression (SVR) • Multiclass Classification As a VIP bonus, you will also get material for how to apply the “Kernel Trick” to other machine learning models. This is how you can use a model which is normally “weak” (such as linear regression) and make it “strong”. I’ve chosen models from various different areas of machine learning. • Kernel Linear regression (for regression) • Kernel Logistic regression (for classification) • Kernel K-means clustering (for clustering) • Kernel Principal components analysis (PCA) (for dimensionality reduction) Remember – the VIP bonus is only available at https://deeplearningcourses.com/c/support-vector-machines-in-python. See here what linear regression can be capable of: And logistic regression: When the kernel trick is applied! For those of you who are thinking, “theory is not for me”, there’s lots of material in this course for you too! In this course, there will be not just one, but two full sections devoted to just the practical aspects of how to make effective use of the SVM. We’ll do end-to-end examples of real, practical machine learning applications, such as: • Image recognition • Spam detection • Medical diagnosis • Regression analysis For more advanced students, there are also plenty of coding exercises where you will get to try different approaches to implementing SVMs. These are implementations that you won’t find anywhere else in any other course. I’ll see you in class! P.S. As usual, if you primarily use another site (e.g. Udemy) you will automatically get free access (upon request) if you’ve already purchased the VIP version of the course from deeplearningcourses.com.

# Neural Ordinary Differential Equations

December 15, 2018

Very interesting paper that got the Best Paper award at NIPS 2018.

“Neural Ordinary Differential Equations” by Ricky T. Q. Chen, Yulia Rubanova, Jesse Bettencourt, and David Duvenaud.

Comes out of Geoffrey Hinton’s Vector Institute in Toronto, Canada (although he is not an author on the paper).

For those of you who have ever programmed simulations of systems of differential equations, the motivation behind this should be quite intuitive.

Recall that a derivative is the same thing as the slope of a tangent line, and can be approximated by the usual “rise over run” formula for small time steps $$\Delta t$$.

$$\frac{dh}{dt} \approx \frac{h(t + \Delta t) – h(t)}{\Delta t}$$

Here’s a picture of that if you forgot what it looks like:

Normally, the derivative is known to be some function $$\frac{dh}{dt} = f(h, t)$$.

Your job in writing a simulation is to find out how $$h(t)$$ evolves over time.

Here’s a picture of how that works (using different symbols):

Since our job is to find the next value of $$h(t)$$, we can rearrange the above to get:

$$h(t + \Delta t) = h(t) + f(h(t), t) \Delta t$$

Typically the time step is just $$1$$, so we can rewrite the above as:

$$h_{t+1} = h_t + f(h_t, t)$$

Researchers noticed that this looks a lot like the residual network layer that is often used in deep learning!

In a residual network layer, $$h_t$$ represents the input value, $$h_{t+1}$$ represents the output value, and $$f(h_t, t)$$ represents the residual.

Here’s a picture of that (using different symbols):

At this point, the question to ask is, if a residual network layer is just a difference equation that approximates a differential equation, can there be a neural network layer that is an actual differential equation?

How would backpropagation be done?

This paper goes over all that and more.

Recommender Systems and Deep Learning in Python September 13, 2018 ### Recommender Systems and Deep Learning in Python So excited to tell you about my new course! [if you don’t want to read my little spiel just click here to get your coupon: https://www.udemy.com/recommender-systems/?couponCode=LAUNCHDAY] Believe it or not, almost all online businesses today make use of recommender systems in some way or another. What do I mean by “recommender systems”, and why are they useful? Let’s look at the top 3 websites on the Internet, according to Alexa: Google, YouTube, and Facebook. Recommender systems form the very foundation of these technologies. Google: Search results (why Google is a billion dollar company!) YouTube: Video dashboard (and recommendations to the right of every video) Facebook: News feed This course is a big bag of tricks that make recommender systems work across multiple platforms. We’ll look at popular news feed algorithms, like RedditHacker News, and Google PageRank. We’ll look at Bayesian recommendation techniques that are being used by a large number of media companies today. But this course isn’t just about news feeds. Companies like AmazonNetflix, and Spotify have been using recommendations to suggest products, movies, and music to customers for many years now. These algorithms have led to billions of dollars in added revenue. So I assure you, what you’re about to learn in this course is very real, very applicable, and will have a huge impact on your business. For those of you who like to dig deep into the theory to understand how things really work, you know this is my specialty and there will be no shortage of that in this course. We’ll be covering state of the art algorithms like matrix factorization and deep learning (making use of both supervised andunsupervised learning), and you’ll learn a bag full of tricks to improve upon baseline results. Whether you sell products in your e-commerce store, or you simply write a blog – you can use these techniques to show the right recommendations to your users at the right time. If you’re an employee at a company, you can use these techniques to impress your manager and get a raise! I’ll see you in class! GET THE COURSE NOW Note: this course is NOT a part of my deep learning series (it’s not Deep Learning part 11) because while it contains a major deep learning component, a lot of the course uses non-deep learning techniques as well. The deep learning parts apply modified neural network architectures and deep learning technologies to the recommender problem. Go to comments # Special Announcment: Deep Learning Keras Book! September 12, 2018 # Simple Deep Learning for Programmers ### Learn Deep Learning via Keras examples with absolutely no math I’m always intrigued when students tell me they want to learn deep learning without doing any math. I was explaining to someone just yesterday – if you look at <insert famous deep learning book by famous deep learning researcher here> – the entire thing is actually cover to cover equations. Ha! Anyhow, I wanted to test this hypothesis. How far can one get, if they try to learn deep learning via an API? So I made this little book. It’s full of Keras examples, starting from a basic feedforward neural network, then adding some modern techniques like dropout and batch norm, then moving to more advanced architectures like CNNs and RNNs. Of course, if you are a reader of my newsletter, you probably aren’t afraid of math! But, I thought I’d share this book with you anyway, since it contains some interesting examples that you haven’t seen in my courses before. – CIFAR dataset – time series prediction using an RNN – machine translation using a Bidirectional RNN (not a seq-to-seq model as in my Advanced NLP course) This would also be a great opportunity to brush up on your Keras skills, which are going to be useful for my next course (hopefully coming out in a few days!) Finally – I’ve also linked below my related book, “Simple Machine Learning for Programmers” – it is a similar experiment in teaching about machine learning using an API with no math. It’s the same as the machine learning section of my Numpy course but I know some students like to have written versions of things so they can read on the subway / airplane. If so, check it out!

# FREE Updates to NLP: Deep Learning for Beginners!

July 15, 2018

You may have noticed that my course Natural Language Processing with Deep Learning in Python has gotten a lot longer recently!

As part of my course revitalization process, I’ve added a significant number of updates to this course.

All students are receiving this announcement because no matter what skill-level you’re currently at, you will get a lot of value from this update.

What has changed?

A brand new section called “Beginner’s Corner”. This section requires only basic machine learning knowledge. Know what a feature vector is, and know how to use the SciKit-Learn API.

You will get a taste of what word2vec and GloVe vectors can do.

You can still get a good understanding of what the course is about even if you’re not (yet!) ready to tackle the rest of the course.

A brand new “Review” section has been added. This section focuses on the bigram model, and several ways to implement it.

1) Just counting. For example, p(heads) = # heads / # total.

2) A single neuron (logistic model). We show how this is equivalent to #1.

3) A neural network model. We show how this actually makes #2 more efficient.

Crucially, this section provides you with all the techniques you need to tackle the next section on word2vec.

The word2vec section has also been completely re-done in order to take advantage of the concepts learned in the Review, making the transition seamless.

Finally, a brand new section on word vectors unifies the word2vec and GloVe sections, giving you a totally new (and in my opinion, better) way of training word2vec.

Additional theory lectures and Tensorflow code have been added to the RNN and Recursive Neural Network sections. Recall: the latter is a neural network structured like a tree.

Yes, Tensorflow’s capabilities have caught up! We can now do everything in Tensorflow that we’d previously done in Theano.

So if you’ve been avoiding these sections because you didn’t know Theano, now you have no excuse. =)

Click HERE to get the course if you don’t have it yet.

Hope you enjoy the updates, happy learning!
