Unlock Your Inner Sherlock Fire: Analytical Minds Need to Journal

Posted on by Billy

While crunching numbers and dissecting data might be your forte, there’s a valuable tool waiting to be unlocked: journaling. Yes, journaling. Don’t let the seemingly sentimental vibe fool you; for those who thrive on logic and reason, journaling offers a surprising treasure trove of benefits.

Journaling 101:

Let’s break it down. Journaling simply means capturing your thoughts and experiences in writing. Whether you prefer the tactile satisfaction of pen and paper or the convenience of digital apps, the choice is yours. Both offer unique advantages:

  • Digital: Quick, portable, and easily searchable, perfect for on-the-go capture and organization.
  • Analog: Creates a tangible connection to your thoughts, fostering deeper reflection and mindfulness.

Unlocking the Power:

As an analytical thinker, you might wonder what journaling has to offer. Here’s the secret: it pushes you outside your comfort zone. It’s less about numbers and models, and more about exploring emotions, motivations, and personal growth. This activates a different set of skills and is also valuable to nurture and grow.

Journaling also helps recenter yourself. Immersing yourself in your thoughts allows you to step back, analyze patterns, and gain clarity on your life’s direction. Think of it as a mental detox, clearing the clutter to see the bigger picture.

My Journey with Journaling:

Here’s how I’ve incorporated journaling into my personal life:

  • Gratitude Journal (Daily): Just a few lines each day, expressing appreciation for the good stuff, big or small. It’s a simple practice with powerful impact, shifting focus towards positivity.
  • Analog Journaling (About 3 times a week): Longer entries, delving deeper into thoughts, experiences, and challenges. This allows for introspection and contemplation, fostering self-awareness and growth.
  • Random Thoughts Journal (As Needed): Need to clear your mind? Jot down those fleeting thoughts and ideas. This helps declutter your mental space and can spark inspiration for further exploration.

Getting Started:

Don’t feel intimidated! Start small and find what resonates with you. Here’s my advice:

  • Begin with Random Thoughts and Gratitude: These are low-pressure, easy to maintain, and require minimal time (5 minutes a day can work wonders!).
  • Gradually Explore Analog Journaling: Start with shorter entries and gradually increase the duration as you get comfortable. Even aiming for 15 minutes 3 times a week can be a great initial goal to help get started!
  • Find Your Tools: Whether it’s a simple notebook or a dedicated app, choose something you enjoy using. I find using Noteability on my iPad with an Apple Pencil feels surprisingly like analog writing.

Remember, this is your journey. Experiment, discover what works for you, and unleash the hidden potential within your analytical mind. You might be surprised at the insights and growth that journaling unlocks. So, grab your pen, open your app, and embark on this exciting adventure of self-discovery!

Friendly Fire to Explainable AI: How to Trust Algorithms

Posted on by Billy

OpenAI’s recent collaboration with the Pentagon on cybersecurity and veteran suicide prevention projects has sparked important conversations about the ethics and implications of artificial intelligence in critical, high-stakes domains. While OpenAI assures responsible development and a ban on weaponry, there’s one crucial consideration that deserves further attention: explainability.

When dealing with applications that carry life-altering consequences, opaque AI algorithms simply aren’t good enough. Take, for example, a predictive model informing veteran suicide risk. A black box churning out a binary “high risk” verdict without explanation is ethically unjustifiable. Imagine the immense psychological burden on the flagged individual, the potential harm of unwarranted interventions, and the erosion of trust in the system (see Dr. Pershing in Season 3 Episode 3 of the Mandolarian for an example of a patient receiving unhelpful care from an AI robot/droid).

Explainability transcends the “right to know.” It’s a moral imperative in critical applications. In healthcare, understanding why a diagnosis is reached guides treatment decisions.  In law enforcement, knowing the reasoning behind suspect identification ensures fairness and accountability. These principles extend to the military, where AI-powered algorithms might contribute to targeting decisions or risk assessments (To be clear, DARPA has been thinking about these sorts of issues).

The stakes are simply too high to rely on blind faith in an algorithm’s output. We need models that not only deliver accurate predictions but also offer clear, human-interpretable insights into their reasoning. This allows for:

  • Accountability: When wrong decisions are made, explainability facilitates tracing the error back to its source, enabling improvement and mitigating future harm.
  • Building trust: Transparency fosters trust between humans and the AI systems they interact with, crucial for long-term acceptance and effective collaboration.
  • Human oversight: Even with advanced AI, critical decisions ultimately lie with humans. Explainability empowers humans to understand the AI’s reasoning, challenge its conclusions, and ultimately make informed judgments.

Fortunately, advancements in AI research are paving the way for more explainable models.  From feature importance analysis to bread and butter machine learning approaches, various techniques offer glimpses into the inner workings of algorithms. While challenges remain, the pursuit of explainable AI is not only a possibility, but a pressing necessity.  I provide an overview of explainable AI in my textbook chapter, “An Overview of Explainable and Interpretable Artificial Intelligence”.

This blog post is just a starting point for a broader discussion. Do you think explainability is truly achievable in complex AI systems? How can we balance accuracy with transparency in critical applications? Let’s work together to ensure AI, with all its potential, is used for good, and explainability plays a key role in that journey.
