How to use modular data architectures to efficiently generate & test hypotheses.

I’m a data scientist so in my case, this applies to testing theories captured in data — however, think of this as a specific instance of a broader problem-solving approach.

Here I provide a paradigm for handling complexity through modular design.

Example Problem Background

As a component of my Masters degree I’m studying how individuals are able to learn under uncertainty. To achieve this we’re designing a mathematical construct to examine the…


Here I provide a review of recent advancements in the intersection between computational mathematics, material science & chemical engineering.

#PaperReview

Overview

This study made a multitude of notable contributions:

1. Automated Data Labeling

Fast Fourier Transforms were used to label the data in an automated & reliable manner.

2. Defect Identification

Deep learning was used to map breeches in lattice periodicity to atomic defects in Mo-doped WS2 — effectively identifying atomic defects in the data.

3. Defect Classification


Applications of Deep Learning in Material Science & Chemical Engineering

Applications of Electron Microscopy

Electron microscopy — a method of generated nanoscale and mesoscale imagining by capturing how electrons interact with materials — is becoming increasingly powerful.

EM hosts a series of important applications:

Life Sciences

  • Microbiology: providing insight into the microbiology of bacteria, viruses & other cells.
  • Medicine: Offering insight into disease diagnostics and damaged issues/cancers.
  • Forensics: Trace evidence such as gunshot residue, hairs, fibers, glass paint fragments, and fingerprints.

Material Sciences

Quality of materials ensuring that they are fit for purpose, preventing material failure, and designing new materials. Playing an essential role in aerospace, electronics, chemistry, and energy.

Semiconductor Sciences

Detailed topographical information is vital to developing…


#Poem

Come as you are,

Go when you please.

Should I wonder how & when you might leave?

Or focus on how you differ from me?

Or try to change you, meticulously?

Forget all of that, & thank you, for now

The laughs. & quarrels. The jokes you allow

Change is the only constant, we know

One day soon, we won’t exchange “hello’s”

No matter for this! This moment? I’ll savour!

For the contrast in life, is where we find flavour.


Investment Thesis

Can individual investors expect high yield on short term equity portfolios?

Problem Specification

Suppose you want to build a sound investment portfolio. Suppose, further, that you’ve settled on a long-term strategy. A problem arises:

How should short term funds be handled?

Short-term investment requirements are often disjoint from their long-term counterparts. Short term investment often acts to:

  • Save for a particular event.
  • As a safety buffer.
  • Have higher liquidity & stability requirements.


Sometimes existence feels deplorable, other times, bliss. We cannot improve what we do not measure — so why not reverse engineer human emotion?

Is it possible to define happiness as a set of non-linear basis functions that capture societal interaction effects?

Formalizing Happiness

Before we can capture any natural phenomena — which is infinitely complex — by some statistical framework we need to formalize the search space (imposing simplifying constraints). …


Make Science Fun.

A comical guide to Reinforcement Learning; Bayesian Statistical Updating & the Exploration vs Exploitation Paradigm.

So you’re the kid who got 100 for every math & physics test, you’ve read Hagel, you compose like Bach, you think in machine code, life is easy, thinking is fast (& slow), tasks are simple.

But there’s a problem… Girls don’t seem to care?!

So, if you’re growing tired of winning the olympiads but not having anyone to celebrate with :( ... At last! I have the answer for you my present-day progressive Picasso.

So ponder no longer my postmodern Pascal. Here’s how we…

#Poetry

Run in the forest.

Run fast.

Alone.

Faster & further than you thought you could.

Sprint until your legs give way, you slip and fall & your knees bleed. Look around & realize where you are — in the forest, alone. And the forest doesn’t care about your bloody knees — so you’ll get up & run again.

Without your knowing, nor your consent, the world of things will recede around you & you’ll be left with nothing but the metaphysics of being.

Your mind & heart race as fast as blood pumps through your veins. Now you feel…
