Machine Learning Lecture

 Machine Learning

What is machine learning?

A subset of artificial intelligence (AI) that focuses on the development of algorithms and statistical models that enable computers to perform specific tasks without explicit instructions. Instead of being programmed to perform specific tasks, these algorithms learn from and make predictions or decisions based on data. 

To further our understanding, Dr. Schuman introduced us to Tensor Flow. The user draws a bit of the selected object, and then the machine completes the drawing.
I simply drew a vertical line, and then the application completed the rest of the drawing!

Lastly, she let us play around with Teachable Machine , in which we programmed our camera to distinguish things; in my case, my face from my water bottle.

Relevance

I've previously blogged about bias within machine learning. Racial bias was especially prevalent within the Teachable Machine, as one of my friend's application assumed three differnent Indian girls (including me) as the same person. Simple activities such as these two websites emphasize the bias within machine learning. However, machine learning is still beneficial for automation of tasks and handling large amounts of data.

June 27: Op-Ed

Cost of Insulin is Up, We're Down

I did not care much for sports, and I especially disliked running. But there I was, running in circles with my family, lap after lap. It was 2019, and we were raising money for the Junior Diabetes Research Foundation (JDRF), a nonprofit organization funding research for type 1 diabetes and treatment. In 2016, my dad was diagnosed with type 2 diabetes, and I was made aware of another health detriment in our world. My family in India, both grandfathers and all of my dad’s brothers, have diabetes. As I grew older, I noticed the prevalence of diabetes in the people surrounding me too, in my friends, younger than me even.
Diabetes is defined as the body unable to produce insulin, a hormone that regulates glucose within the body. Prices for diabetic medication have inflated since the 1920s. In 1996, Humalog was sold for $21; in 2019, for $300. There still is no cure for diabetes, but the remedies should not be unattainable to those that are financially unstable; priority is taken away from effective medications and instead the focus is on the affordability. But people should not have to worry about the affordability of a product their body is unable to produce. 
The high cost of insulin is an effect of the virtual monopoly on insulin that has been sustained for decades. Three companies-Novo Nordisk, Sanofi-Aventis, and Eli Lilly-control 90 per cent of the global insulin market, being the only producers until recently. Because of their hold over insulin products, these three companies were coined “The Big Three”. As “The Big Three”, these companies function as monopolies, able to charge higher prices for insulin. Being the main producers, consumers are basically forced to purchase insulin at these higher prices if they wish to survive. The monopolists take advantage of the fact that the consumers need insulin to live.
My friend that is a year younger than me showed me his blood sugar tracker, and explained that the price is similar to that of a phone. With how prevalent diabetes is, why does it cost as much as a phone does? Today, we consider phones essential to society; however, phones are just advanced technology that allow us to easily communicate. The blood sugar tracker on the other hand is a necessity for one’s survival, and yet it is as expensive as one of society’s indulgences. Adjustments to the prices of such products must be made. Even though the technology is medical grade, it is meant for a common person’s use, so it should be made more affordable, like an over the counter medicine is.
In 2018, the average American insulin user paid $3,490 for insulin. In Canada, $725. Already the money spent on insulin was grand, so in 2024, six years later in a world where inflation is as normal as the sky being blue, the cost for insulin for the average American is sure to have surpassed the cost in 2018. Spending in the thousands for insulin is unreasonable for America. Even though the United States is a first world country, it houses 37.9 million Americans living in poverty, 11.5% of the American population. People with type 1 diabetes inject insulin four to five times, every single day. For the poor, paying for insulin is unsustainable if the cost is in the thousands. Even for the middle class, the cost is unreasonable. If the price is in the hundreds in Canada, then America too can adjust the cost of insulin.

June 21: Ecological Self Maps and Natural Areas Observations

Ijams Nature Center

Unplug

    The first thing that hit me was the amount of green, so much vibrant green. As the objects became clearer, I distinguished the trees-the brown bark dressed in green leaves, the brown trail scattered with twigs outlined by green bushes. I felt the moisture from the humidity, but the tall trees provided shade from the shining sun and I felt a light breeze throughout my day. Even with the entire Governor's School populace at the center, it was relatively quiet. Though the birds were chirping and students discussed around me, the sound wasn't overpowering, and instead just the right amount of noise to make me feel included in society but also giving me alone time. Despite my conjested nose, I could smell essential oils such as sunscreen and bug spray.
    As an anxious person who plans for everything, being at the nature center made me live in the present. There was no "what happens next", only what I'm looking at now. I think I didn't feel anything, but that's not a bad thing. Rather, it means I was at peace, simply living.


Animals

    I noticed an insect jumping on the pond water. It could've been looking for food, or maybe shade, but I can only assume. Though the animal meets the qualities of personhood such as sentience, rationality, and self-awareness, I did not observe any communication, emotions, or morality displayed by the insect. The insect only interacted with the abiotic water of the pond; it didn't even jump on a lillypad, it could "swim" on it's own I guess. Though there was a frog in the pond, it didn't stick out it's tongue to consume the insect, but from the food cycle, that is what I would assume would happen to the insect. Maybe that's why the insect was gliding through the pond...I do believe that every action displayed by the insect was intentional, but for what purpose I don't know.


Artifacts

    I felt many spiderwebs on my legs and arms as my group walked through the center. We observed one web that actually had a spider in it, too. The web is made out of silk which comes from the spider's abdomen, which the spider will weave using its legs. Though the web provides a sanctuary for the spider, it works as a trap for other animals, providing the spider food.


Explanatory Paradigms (Spiderweb)

  • Anthropocentric Hierarchy: The spider is second to humans; however, the web is the lowest on the hierarchy as it is inorganic. The purpose of the web is to capture insects for the spider, but I believe the web provides biodiversity as it works as "insect population control" for humans
  • Natural Selection: The spider has adapted to be superior by establishing webs to trap other insects for consumption.
  • Ecocentrism: The web is not any less worthy than the spider that created it or the people that observe it.
  • MSE: The spiderweb is made from silk, which is a natural polymer. Spiderweb silk has tensile strengths comparable to steel. Because of the disorderly arragnement of the glycine-containing protein molecules, spiderweb silk has good elasticity and stretchability.

June 17: Visualization and AI Overview

 Data Visualization


I made this on Excel following a YouTube tutorial. By depicting the data in this manner, the information is easier to perceive, as the extent/greatness or minuity of a number is emphasized through these visuals. However, it took me two days to finish this because I was losing patience, and even still, I forgot to change "# of Customers" and only just noticed that error.

June 14: CAFOs

 Should CAFOs Exist?

What is CAFOs? 

  • Concentrated Animal Feeding Operations
  • facilities that stable, confine, feed, and maintain animals for consumption

Group's Opinion

We agree that CAFOs should exist.
  • efficient economically
  • efficient use of land space
  • better to breed animals for consumption from the get-go because they will die in the end, rather than show them love and care and then eat them

June 13: Are Animals People?

 How Do You Treat The Animals In Your Life?



Advanced Sciences Field Trip to Memphis Zoo 

(5/20/24)

I don't have any pets, so the only animals I regularly interact with is the meat I consume. Though I do not hunt animals, when I consume them in curry, my mind is so distanced from the fact that I'm consuming something that was once alive. At that point, the animal is inanimate in the food form. However, the animals that I see alive, such as the ones in the zoo, I pitied, for they were alive but being held captive for display. I'm no animal lover, but I am cordial with pets and I want a hamster. I don't think it is correct to hunt animals for sport or hold them captive for display, but eating the animal or taking care of it as a pet are acceptable.

June 11: Objectivity?

Objectivity

Pitbull and Bunny


Neutral Description

There is a pitbull licking a bunny. The bunny moves away from the pitbull, but the pitbull comes closer to continue licking the bunny. The bunny is cleaning itself because the pitbull is applying spit to the bunny, as both dogs and bunnies clean themselves using their saliva.

My Interpretation

In my eyes, I felt like the bunny was moving away from the pitbull, but the pitbull kept moving closer to lick the bunny. However, the bunny was not trying to runaway as if sensing danger, but just moving away to properly clean itself without the pitbull's hinderance. I came to this conclusion because the bunny was jumping away, but not in a hurry as if trying to escape, allowing the pitbull to lick it.

Improving Objectivity

To reduce bias, I would need to consider the actions displayed in the video without my own personal experienced. Because of these observed patterns, I am left to assume what is going on in the video, which introduces bias as I perceive the actions displayed differently to what others assume and what is actually happening in the video.

Fresh Outlook

After rewatching and discussing the video with the class, my opinion did not change regarding the bunny moving away from the pitbull. However, I will add that maybe the pitbull is licking the sweat off the bunny as well or assisting the bunny in cleaning itself, perhaps feeling motherly towards the bunny.

June 10: 3D Printing

 3D Printing

Background

  • YouTube Videos of people using 3D print pen
  • Science Olympiad members 3D printing parts

Software

I used TINKERCAD because though I have seen other people 3D print, I have never designed and printed my own. As TINKERCAD was the basic 3D print option, I followed through with that.

My Design

Originally, I wanted to create Miffy (Dutch children's story bunny character) or a Sonny Angel (collectible baby miniture). My friend Disha Javagal decided to design an Among Us character, and I, after struggling with even the basic TINKERCAD lessons, decided to join the fun and create an Among Us character as well. 

Front


Side

Back

Even with its simple shapes, this Among Us design took me two days to "perfect". Because at least four people in my friend group designed Among Us characters, we decided to put our intials on the back of our personal design to diffrentiate our prints! My Among Us 3D print design is brown and sports bear ears to replicate my in-game character.

What I Learned

  • add fillets to support upright design
  • know the pen size of the 3D printing machine
  • keep angles less than 45 degrees
  • when printing detail work, print two designs side by side so the pen can work on both parts, providing time for the plastic to cool
  • how to navigate TINKERCAD

June 7: Computational Thinking

What do ghosts that can code say?

BOOlean!!

Coding Blog 

Background

  • SCRATCH in elementary school
  • AP Computer Science Principles in 10th grade

Python

Because of my inexperience with coding, I decided to complete the Codeacademy modules to truly learn Python. I completed 19% of the expected 30% of the course, learning about lists, date and time, strings, integers, float, boolean, and just basic Python Syntax. Lists where challenging for me, because I kept mixing up whether to use quotation marks or parantheses, and when integers and strings were introduced, creating lists became even more challenging. I still need more practice to get comfortable creating my own lists, but Codeacademy provided a beneficial introduction to Python.

June 6: Pseudoscience

Is SETI Science or Pseuodoscience? 

Science vs. Pseudoscience

  • science - explanation for every phenemonen based on quantitative data; a conclusion CAN be proved false
  • pseudoscience - statements, beliefs, or practices that claim to be scientific but are incompatible with the scientific method; a conclusion that CANNOT be proved false

What is SETI?

SETI is an acronym for the Search for Extraterrerstrial Intelligence.

Group's Classification

My group (Disha Javagal, Aditi Arunprakash, Carolin Chou, and Sanvi Guruprasad) concluded that SETI is science. Though both science and pseudoscience rely on experimentation, pseudoscience establishes conclusions based on qualitative obeservations whereas science establishes conclusions based on quantitative data. We feel that for SETI to be pseudoscience, then the statement would be "because there is life on Earth, there can be life elsewhere" simply based on that observation. In contrast, SETI analzes frequency in Hertz (https://www.space.com/cosmic-seti-alien-life-search-underway) and uses the Drake Equation (https://www.seti.org/primer-seti-seti-institute) to expand the research. Additionally, the technology currently available may not be advanced enough to draw a clear conclusion, considering SETI in the first stages of experiementation.

My Classification 

I also classify SETI as science in the first stages. By the definition that science is an explantion for every phenomen that is falsifiable through quantitative data, SETI is simply researching the question of if there is extraterrestiral intelligence.

Pseudoscience Classification

  • no result
  • unreliable statistical analysis of the universe
  • research seems to be attempting to prove a preconcieved conclusion rather than evidence supporting a claim

Further Examples of Pseudoscience

  • astrology/horoscopes
  • traditional medicine
  • alchemy
