Newsletter November Part 2

Exclusive right has been retained to repost this on the internet. Uniqtech only posts on,, and here occasionally. All other posts are not authorized, may contain malicious links. In this special edition, we will talk about both machine learning (our usual data) as well as web3 - the next evolution of web. In the next newsletter, in early December, we will also analyze the job postings of a few web3 and blockchain companies such as NFT marketplace OpenSea. Our staff recently attended their recruiting event. Blockchain curriculum and flash cards are available for pro members at NO additional charge. It's included in your $5 / month membership! Yay. 

Blockchain and web3 seem to be the future, though Elon Musk surely disagrees (he tweeted today), though he seems to support Dogecoin. Art Basel, a premium fine art, NFT art, and blockchain art fair is happening today in Miami, the city of crypto.

Because blockchain is a public, distributed database, we data people, machine learning practitioners won't be in foreign territory. What we know have a lot of synergy! If you know web development, even better. 

A reminder : you can log into the website with either gmail or github! 😸 The technology is Google Firebase Authentication. cheers

In the past, we discussed the preprocessing, vector representation aspect of deep learning models. Data cleaning and processing should take up to 80% of machine learning practitioners' time, but today we need to address the elephant in the room : deep learning training. This is both the art and math of AI. In the machine learning section, we will discuss training loops.

This newsletter's mega topic


Today's main focus in Machine Learning training is : training loop and gradient

What is training? Training is the learning part of "machine learning". In iterative processes, your models compare predictions (y_hat) with ground truth (y) in supervised learning. Then it will compute a heuristic of distance, which represents how good or far off is the prediction, also represents how distant is the prediction from the ground truth. Your models' goal is to minimize the distance using math and algorithms tricks, educated guess, even randomization. 

Depends on the metrics chosen, the distance result in very different numbers. There are strengths and weaknesses of each distance function, making each of them suitable for different tasks. There's no one magical distance function. An example of distance function in regression is euclidean distance. An example of distance function in classification is multi-class cross-entropy. In some scenarios, when comparing two vectors, their dot product can be used as the distance function. The choice of distance function takes trial and error. And can be an art. 

Check out the machine learning flash card landing page for more information on training APIs how the .fit function in scikit-learn different from pytorch custom loop.

Because of the interdisciplinary nature of machine learning (a perfect partnership of math, statistics, computer science, probabilities, even biology, neuroscience and more), there are often different versions and names for the same terminology. It's confusing for beginners, even experts. Other names for distance function are similarity measures, loss function, cost function. 

We won't be able to explain and teach the training loop in one newsletter. We will need to create a series of youtube videos for our subscribers. But we want to show you the codes, line by line, and what's the purpose of each line. How does pytorch training loop differs from Tensorflow? 

On the machine learning flash card landing page, we explained tensorflow and scikit-learn has a high level API .fit() To train a model you just have to call the fit API on X(input) and y(output) in supervised learning. The pytorch custom training loop is a bit more involved. Just a few more lines of code. You can also write custom loops in Tensorflow. In this newsletter we just want to link to the source code. Don't worry about understand every little detail. We will want to record videos that explain these algorithms line-by-line. But if you take a close look, the training loop is under 50 lines of code. That's pretty manageable! Don't be intimated. If we learn one section a day, we will be done in a week. 

Pro members check out the pytorch custom training loop, annotated here, in this flash card. 

Annotated flash card for pytorch training loop source code

"sklearn (scikitlearn) and keras just call .fit() to train. The format is, y_train). In Pytorch you will have to do a bit DIY your own custom training loop."

Tensorflow also supports custom training loop [pro, tensorflow, training, ]

How to play sandbox play-to-earn game strategy guide

Strategy guide and walkthrough for Sandbox alpha

wasd keys for directions 

space bar for jumping

T for emote

shift + w forward + sprinting

debugging: your browser is not compatible, your browser is not supported. Solution : use the latest chrome.

Only those with alpha pass unlocks the entire alpha week content and can earn the highest price.

Those without alpha pass can purchase (very expensive on opesea $10,000 US ++ and filled with spammers), or play Alpha Quest and participate in official twitter daily contest to win.

Must participate by replying on the day of, with a screenshot, and fill out a google form with wallet address, and link to tweet (of screenshot) to win.

There are at least three other tasks that can be done by non-alpha-pass holders: visit each fraction land, count deer, lynx, brown bear (6,5,2 depends on the order you are asked, you can actually guess this one multiple times instead of counting it. this is not the number in the market. It's literally in the alpha land you are in right now), fix a few beacons (locating the 5 beacons) .

Some beacons are hard to find. Be sure to use jumping (space bar) to access some places. Look for ladders and stair cases. We will show you below.

picture : in october snoop dog ran a contest for his private party pass

Day 1 create avatar, post screenshot, link to it in google form

Day 2 take a picture with snoop dog... same as above

Day 3 Get lasered by the Bored Ape with laser eyes!  

When doing tasks look for these yellow indicators. They tell you where to go. They are helpful. 

You can get the beacon task from this dude. 

Visiting different fractions. Their land are different colors. When you enter the world, go through the hall way almost to the laser eye ape, on the first floor, behind a different statue, that's the open field to the 3 fractions. 

Quest: how to locate and repair the beacons in sandbox alpha

Get the counting task and answer to this dude. You can take a guess instead of counting.

For fun, you can dance Gangnam style, use T for emote

Type in /help in chat for commands.

One beacon is located at a tough to spot place, you have to jump off a ledge to see it. 

One is on top of these building, enter one of the room, for the secret stair case to the top.

Tough to find 

Final one is in a house filled with fish, the stairwell looks like this.

For day 1 you have to hang out with snoop dog.

Blockchain, cryptocurrency, NFT, DAO Lifestyle

Welcome to the crypto renaissance! Live a futuristic, ideal, cool lifestyle in Web3, enabled by blockchain technology, cryptocurrency, and DAOs. 

Why is NFT so popular right now? NFT made many price records in 2021: "Decentraland, most of the recent headlines have been about digital art being sold for eye-popping prices. This includes a $560K New York Times column, Beeple’s $69M JPEG, a $7M Cryptopunk icon, and Jack Dorsey’s $2.9M tweet, among others." CBInsights

Crypto cities:

First, warning, please read our disclaimer: 



Famous NFTs : Bored Ape Yacht Club (BAYC), Degenerate Ape Academy, and CryptoPunks. All are on OpenSea. Watch out for copy minters elsewhere. Each NFT has different traits properties, some are digitally rare, and perceived to have different personalities, different desirability. A common thread: red laser eyes are considered crypto maximalists, and are expensive


#NFTNYC, largest NFT conference, 

Bored ape yacht club party, warehouse event, and exclusive meetup

NFT Use Case: 

NFT can partner with consumer brands. NFT can be luxury goods. NFT can be wearables. NFT can deliver fashion : Karl Lagerfeld, fashion icon, figurine sold out in less than one hour. 


What can be tokenized? It seems that everything is being tokenized. Art, NBA plays, 

blockchain data technical challenge : correctness, sync, real time, reliability, up time, scalability, connection to the chain
