Limitations of the ChatGPT and LLMs - Part 3
If you haven't watched the Part 1 and Part 2, I highly suggest watching them before watching the Part 3.
Large Language Models (LLMs) have shown a huge potential and recently the have drawn much attention. In this presentation, Ameet Deshpande and Alexander Wettig gives a detailed explanation about how Large Language Models and ChatGPT works. He makes clear that he does not assume that the audience has any prior knowledge about language models. He starts with embedding and give an explanation about Transformers as well. This is the last episode of this amazing serie. Thanks for watching.

Understanding BERT Embeddings and How to Generate them in SageMaker
zhlédnutí 4,5KPřed rokem
Course link: www.coursera.org/learn/ml-pipelines-bert In this course, you will use BERT for the same purpose. Before diving into the BERT algorithm, I will highlight a few differences between BlazingText and BERT at a very high level. As you can see here, BlazingText is based on Word2Vec, whereas BERT is based on transformer architecture. Both BlazingText and BERT generate word embeddings. Howe...
Understanding Coordinate Descent
zhlédnutí 7KPřed rokem
Course link: www.coursera.org/learn/ml-regression let's just have a little aside on the coordinate decent algorithm, and then we're gonna describe how to apply coordinate descent to solving our lasso objective. So, our goal here is to minimize sub function g. So, this is the same objective that we have whether we are talking about our closed form solution, gradient descent, or this coordinate d...
Bootstrap and Monte Carlo Methods
zhlédnutí 7KPřed rokem
Here we look at the two main concepts that are behind this revolution, the Monte Carlo method and the bootstrap. We will discuss the main principles behind these methods and then see how to apply them in various important contexts, such as in regression and for constructing confidence intervals.

Maximum Likelihood as Minimizing KL Divergence
zhlédnutí 2,8KPřed 2 lety
While the Bayes' formula for the posterior probability or for parameters given the data is very general, there are some interesting special cases where that can be analyzed separately. Let's look at them in a sequence. The first special case arises when the model is a fixed one and for all. In this case, we can drop the conditioning on M in this formula. The Bayesian evidence, in this case, is ...
Understanding The Shapley Value
zhlédnutí 14KPřed 2 lety
Shapley Value is one of the most prominent ways of dividing up the value of a society, the productive value of some, set of individuals among its members. The Shapley Value is, is based on Lloyd Shapley's idea that members should basically be receiving things which are proportional to their marginal contributions. So, basically we look at what, what does a person add when we add them to a group...
Kalman Filter - Part 2

Course Link: www.coursera.org/learn/state-estimation-localization-self-driving-cars Let's consider our Kalman Filter from the previous lesson and use it to estimate the position of our autonomous car. If we have some way of knowing the true position of the vehicle, for example, an oracle tells us, we can then use this to record a position error of our filter at each time step k. Since we're dea...

This course will introduce you to the different sensors and how we can use them for state estimation and localization in a self-driving car. By the end of this course, you will be able to: - Understand the key methods for parameter and state estimation used for autonomous driving, such as the method of least-squares - Develop a model for typical vehicle localization sensors, including GPS and I...
Recurrent Neural Networks (RNNs) and Vanishing Gradients
zhlédnutí 8KPřed 3 lety
For one, the way plain or vanilla RNN model sequences by recalling information from the immediate past, allows you to capture dependencies to a certain degree, at least. They're also relatively lightweight compared to other n-gram models, taking up less RAM and space. But there are downsides, the RNNs architecture optimized for recalling the immediate past causes it to struggle with longer sequ...
Transformers vs Recurrent Neural Networks (RNN)!
zhlédnutí 21KPřed 3 lety
Course link: www.coursera.org/learn/attention-models-in-nlp/lecture/glNgT/transformers-vs-rnns Using an RNN, you have to take sequential steps to encode your input, and you start from the beginning of your input making computations at every step until you reach the end. At that point, you decode the information following a similar sequential procedure. As you can see here, you have to go throug...

Course link: www.coursera.org/learn/tensorflow-sequences-time-series-and-prediction Time-series come in all shapes and sizes, but there are a number of very common patterns. So it's useful to recognize them when you see them. For the next few minutes we'll take a look at some examples. The first is trend, where time series have a specific direction that they're moving in. As you can see from th...

will coordinate descent always converge using LASSO even if the ratio of number of features to number of observations/samples is large?
amazing great to see some good content again thank yt algorithm keep it up
best video i've seen on this. great visuals & explanation
This works ok on nice functions like g(x,y)=x^2+y^2 but real data often looks more like Grand Canyon where the path is very narrow and very windy.
No
Great video, you are the best :)
Thanks very much, I was looking for such videos to answer my assignment questions and you answered all of them at once within 3 minutes. I salute you,please keep on do more videos to assist the students to pass their exams and assignments.
Hey! Thanks for the fantastic content :) I'm trying to understand the additivity axiom a bit better. Is this axiom the main reason why Shapley values for machine learning forecast can just be added up for one feature over many different predictions? Let's say we can have predictions for two different days in a time series and each time we calculate the shapley value for the price value. Does the additivity axiom then imply that I can add up the Shapley values for price for these two predictions (assuming they are independent) to make a statement about the importance of price over multiple predictions?
What about self-driving rockets?
Shapley values are great, but not gonna help you much with complex non-linear patterns, especially in terms of global feature importance
what is text regression?
Awesome explanation
Why are the given weights for the distributions, are not really showcasing the distributions on the graph. I mean i would choose π1 = 45, π2 = 35, π3 = 20
Two things: 1. What the H matrix is has not been described. 2. One non s1x1 matrix cannot be smaller or greater then another. This is sloppy. Besides that, it is a great work.
I wish there was a Part 3 :(
Hi, about the sample has X1 to Xn, do X1 and Xn have to be different? Because you have a previous sample of 100 height from 100 different people. Or it can be like we treated in bootstrap that X1* to Xn* can be drawn randomly from X1 to Xn so basically can draw same height of a single person?
Thanks, I can more understand about KF.

Thanks! It's very clear
very good video. perfect explaination!
Thank you so much for your explanation.🎉
Great job, thank you!
Clean explanation. Thank you very much...cheers~
Your explanation was great, thx
Disappointed ☹️ no part 3
Amazing lecture of gnns.
I like your term "Word Algebra". It might be unintended side effect but I have been pondering it for years!
no part 3, sad 😥
Great work..
I believe there might be an issue with the perplexity formula. How can we refer to 'w' as the test set containing 'm' sentences, denoting 'm' as the number of sentences, and then immediately after state that 'm' represents the number of all words in the entire test set? This description lacks clarity and coherence. Could you please clarify this part to make it more understandable?
