Why does every beginner data scientist fall for the "deep learning trap"?

True story 🧵

#rstats #datascience #deeplearning
When I was first learning data science this cost me at least 6-months. Seriously...

I was building a model for predicting which quotes would become orders.
I had just finished using a linear regression (didn't know about logistic yet) to make a predictive model.

Yeah I know - I was a noobie using regression instead of classification. So what?!

What does a data science experiment look like and how do you design the first round of experiments?
1/12
#DataScience #MachineLearning #DeepLearning
Data Science experiments start with a question. How does the business keep customers subscribed or maintain their current level of spending?

Notice this is not the standard definition of churn and there’s a good reason for that.
2/12
#DataScience #MachineLearning #DeepLearning
Take existing data, train models, and compare them (multiple single models and ensembles) to the EXISTING customer retention process’s performance. This is your first experiment! Why haven’t we used a test dataset?

What do model testing and accuracy metrics really tell you about your model's performance in production? Very little.

Test sets provide baseline accuracy metrics telling you how well you've modeled the dataset. That's not enough.
1/7
#DataScience #MachineLearning #DeepLearning
Remember what models learn, a function. That function represents a system like a customer's reaction to an ad or a part of the supply chain.

A trained model learns a function that's only as complete as the training data.
2/7
#DataScience #MachineLearning #DeepLearning
If your data contains all the features and only the features impacting the system/behaviors you’re trying to model
AND
Represents the full problem space, then the function your model learns will perform well in production.

5 years ago, I proposed using #DeepLearning to predict response to immunotherapy in TCR-Seq.
🧬🧬🧬🧬
Last year, we published #DeepTCR. Today, I am proud to share its application in cancer immunology, now out in @ScienceAdvances #ScienceResearch
🔶🔷🔶🔷
science.org/doi/10.1126/sc…
This project started with a hypothesis that if a specific antigen-specific response was characteristic of responses to immunotherapy, then this should be reflected in the TCR repertoire/sequences.

After all, the TCR repertoire is ground truth for the antigen-specific response.
First, we expand the #DeepTCR framework by allowing featurization of the TCR in context of the HLA background it is found within, overcoming the challenge in making direct comparisons of TCR repertoire in HLA mismatched individuals. Image

Took a face made in #stablediffusion driven by a video of a #metahuman in #UnrealEngine5 and animated it using Thin-Plate Spline Motion Model & GFPGAN for face fix/upscale. Breakdown follows:1/9 #aiart #ai #aiArtist #MachineLearning #deeplearning #aiartcommunity #aivideo #aifilm
First, here's the original video in #UE5. The base model was actually from @daz3d #daz and I used Unreal's #meshtometahuman tool to make a #metahuman version. 2/9 #aiartprocess
Then I took a single still frame from that video and ran it through #img2img in a local instance of #stablediffusion WebUI. After generating a few options I ended up with this image. 3/9 #aiartprocess Image

------------------Feature Engineering----------------------

The success of all Machine Learning algorithms depends on how you present the data. Every model gets input data and gives us an output. When your goal is to get the best possible output from input,

1/
You need to present the best data to the model. This is a problem that Feature Engineering solves. Feature Engineering refers to the process of using the domain of Knowledge to extract features from raw data.

2/
In other words, Feature Engineering selects the most useful features from our raw data and presents them to our model, whereby we improve the performance of our model.

(hopefully, you get the point 😀).

Let's assume you have three Features(age, height, salary) in your example.
The first feature varies from 1 to 90. The second one varies from 120 to 210 and the Third one varies from 1000 Euro to 4500 Euro.
#Thread
1/
As you can see the value of your features are in a different range. In this case, if you want to use gradient descent to find optimum parameters for your model( for instance linear regression), that leads to a slow speed of your model to converge. In this case,
/2
you can utilize Feature Scaling to bring the value of features in a range from 0 to 1 depending on the Scaling technique, that you use. So you improve the speed of your model convergence.

As I started to learn Data Science I didn't know what skills should I learn and where. That was a ton of content and I didn't know which one should I take. I have read more than a hundred articles and talk with some of my data scientist friend and gathered experience
1
during my journey. I want to share a roadmap and skills that you need as a junior Data Scientist and resources to learn.

1- Start with a language programming and best of all Python. You can learn Python from 3 resources.
Taking one of these courses is enough.

Using X/Y Plot in a local #stablediffusion WebUI to create contact sheets exploring the latent space for my previous post. As a photo/video person I'm trying to bring the #aiartprocess closer to the workflows I use with clients.1/7 #aiphotography #aifashion #aiart #aiartcommunity
I imagine if you're coming to AI art from a different set of creative fields and client expectations, you'd approach the latent space from a different collection of frameworks and processes. Very curious how different a UI/UX catering to painters could look. 2/7 #aiartprocess
After an exhaustive process of prompting, I use different combos of X/Y Plot to make variations. The image I posted looked at sampler method+step count. Still trying to figure out what flow makes sense for me. I'm sure I'll throw it out as soon as new stuff gets released lol 3/7

سونالی فوگٹ کا کیس جہاں بہت آفسوس ناک ہے

A very good paper I came across this morning by the @DeepMind researchers. For the past five years Transformers have been one of the most dominant approaches to Deep Learning problems, especially in the #NLP domain.

1/5
However, despite many interesting papers on the topic, and lots of good open code, there has been a noticeable lack of *formal* definition of what transformed are, especially on the level of pseudocode.

2/5
This paper aims to rectify that. It provides pseudocode for almost all major Transformer architectures, including training algorithms.

📢 Very excited to see our work #cytoself now published in @naturemethods . #cytoself is a deep learning method for fully self-supervised protein localization profiling and clustering. Led by @liilii_tweet with @kchev @LeonettiManuel at @czbiohub

nature.com/articles/s4159…

1/n
Everything started with a conversation with my friend & colleague @LeonettiManuel who worked on building #OpenCellCZB — a map of the human proteome:

opencell.czbiohub.org

We wondered, can we use #DeepLearning to map the landscape of protein sub-cellular localization?

2/n
The problem with #images , compared to #sequences, is that it is unclear how to compare them. For example, how to estimate localization similarity from pairs of images of fluorescently labeled cells? With sequences we have algorithms and tools. But for images?

The issue with #NP problems is Uncertainty. The greater amount of information about the problem, the less Uncertainty & therefore, the less Computational Complexity. In case of no Uncertainty, NP=P. #NPplusInformationEqualsP @ulisescortes @sierra_carles @vdignum @wooldridgemike
In practice, that's what #DeepLearning does: it gathers data of the problem but runtime is P.
In Research too: we publish about problems until we find a P solution and then we continue optimising the solution in case we need a trade-off PSPACE/PTIME. #AI #MachineLearning
Could we create a Problem Information System to reduce the complexity of Research in general?Could it be automated to the greatest extent? That would be a General Problem Solver. We can be greedy & blindly publish in words everything we might solve, or we could start making a PIS
