Black Box Paradox in Artificial Intelligence (AI)

The Black Box Paradox in AI

One of the early promises of artificial intelligence was that it could deliver the decision making free of discrimination. But the AI has impacted human lives in many aspects and very soon the humans started realizing that artificial intelligence can also suffer from the same biases as the human intelligence.

A few years ago, Amazon mostly abandoned a system it was using to screen the job applicants when it discovered it was consistently favoring men over women. Similarly, in 2019, an ostensibly race-neutral algorithm widely used hospitals and insurance companies was shown to be preferencing white people over black people for certain types of care.

When everyone is hyping that AI provides solutions to every problem, but most of these AI models operate in Black Box i.e. internal workings are a mystery to its users. Users can see the system's inputs and outputs, but they can't see what happens with in AI tool to produce those outputs and this is known as the Black Box Paradox in AI.

The Black Box Paradox refers to inherent opacity of the AI systems, where the decision-making processes are often obscure and difficult to comprehend for humans. This lack of explainability makes it challenging to understand how AI arrives at its conclusions leading to question about transparency, and reliability of the system.

Consider a Black Box model that evaluates job candidates resumes. Users can see the inputs-the resumes they feed into the AI model. And users can see the outputs-the assessments the model returns for the resumes. But users don't know exactly how the model arrives at its conclusions like what factors it considers, how it weighs those factors and so on.

Algorithm of YouTube, Facebook, Instagram can't explain why a particular video gets viral immediately after its upload. This is hidden under many layers of training of the algorithmic model of the YouTube, Facebook, and Instagram.

The Root Cause: Deep Learning

Understanding why this happens requires knowing little bit about how machine learning models are built. 

Suppose you want to teach a child the difference between a Cat and a Dog. You would probably start by showing him a bunch of pictures of both Cats and Dogs, and during that process, the child would absorb some features of Cats 😺 and Dogs 🐕. Then, hopefully, when you show him a picture he never seen before, he can figure out if it's a Cat or Dog.

This method of learning by examples reveals one of the significant ways in which bias can infiltrate a machine learning model. For instance, a facial recognition algorithm is trained mostly on the images of the lighter skinned people, it may lack accuracy in identifying darker skinned individuals.

In much the same way, in real life, people are biased toward the fair skinned people considering them as more beautiful and smarter than dark skinned people because culturally people have deep learning of this thought.

Similarly, Amazon's resume screening model proved to be biased toward men because it was trained to recognize keywords from resumes of its most successful current employees - who were disproportionately men.

The deep learning algorithms are a type of machine learning algorithm that uses multilayered neural networks. Where a traditional machine learning model might use a network of one or two layers, deep learning models can have hundreds or even thousands of layers. Each layer contains multiple neurons, which are bundles of code designed to mimic the functions of the brain.

Deep neural networks can consume and analyze raw, unstructured big data sets with little human intervention. They can take in massive amounts of data, identify patterns, learn from these patterns, and use what they learn to generate new outputs, such as images, video and text.

However, these deep neural networks are inherently opaque. Users-including AI developers -can see what happens at input and output layers, also called "visible layers." They can see the data that goes in and predictions, classifications, or other content that comes out. But they do not know what happens at all network layers in between, the so-called "hidden layers."

Explainable AI (XAI) or White Box AI: Leveraging AI models while ensuring accountability and transparency.

Explainable AI (XAI) or White Box AI is a set of processes and methods that allows human users to comprehend and trust the results and output created by machine learning algorithms.

It is an emerging field that aims to make AI systems more transparent and understandable to humans. It provides the tools and techniques to explain the reasoning behind AI decisions, allowing auditors, analysts, and stakeholders to trace how these decisions are made.

By incorporating XAI, financial institutions can identify and mitigate biases, ensure compliance with regulations, build trust with customers and regulators, and unlock the full potential of AI technology.

It is crucial for an organization to have a full understanding of an AI decision-making processes with model monitoring and accountability of AI and not to trust them blindly. Explainable AI can help humans understand and explain machine learning (ML) algorithms, deep learning and neural networks.

Explainable AI Techniques

1. Prediction Accuracy: Accuracy is a key component of how successful the use of AI is in everyday operations. By running simulations and comparing XAI output to the results in the training data set, the prediction accuracy can be determined. The most popular technique used for this is local interpretable Model-Agnostic Explanations (LIME), which explains the prediction of classifiers by the ML algorithm.
2. Traceability: Traceability is another key technique for accomplishing XAI. This achieved, for example, by limiting the way decisions can be made and setting up a narrower scope for the ML rules and features. An example of traceability XAI technique is DeepLIFT (Deep Learning Important FeaTures), which compares the activation of each neuron to its reference neuron and shows a traceable link between each activated neuron and even shows dependencies between them.
3. Decision Understanding: This is the human factor. Many people have a distrust in AI, yet work with it efficiently, they need to learn to trust it. This is accomplished by educating the team working with the AI so they can understand how and why the AI makes decisions.

Uses of Explainable AI:

• Healthcare: Accelerate diagnostic, image analysis, resource optimization and medical diagnosis. Improve transparency and traceability in decision-making for patient care. Streamline the pharmaceutical approval process with explainable AI.
• Financial Services: Improve customer experiences with a transparent loan and credit approval process. Speed credit risk, wealth management and financial crime risk assessments. Accelerate resolution of potential complaints and issues. Increase confidence in pricing, product recommendations and investment services.
• Criminal Justice: Optimize processes for prediction and risk assessment. Accelerate resolution using explainable AI on DNA analysis, prison population analysis and crime forecasting. Detect potential biases in training data and algorithms.

In conclusion, without knowing how an AI model making decisions leads to the lack of transparency and accountability in the decision making known as Black Box Paradox in AI. This generates confusion, and distrust in AI models. The problem can be addressed with the use of Explainable AI (XAI) which gives the detailed understanding of the process of decision making and leading to the better use of AI models while ensuring accountability and transparency.

The Pillars of Organizational Leadership: Nurturing a Belief System That Drives Success

In the realm of organizational leadership, success is often measured not only by profit margins or market dominance but also by the ethos and culture that underpin the company's operations. At the heart of this lies a belief system—a set of values, principles, and ideologies that guide decisions, actions, and relationships within an organization.

Allow me to illustrate the transformative power of a robust belief system through a story that encapsulates its essence.

====================

Once upon a time, in a bustling city, there stood a company named "Phoenix Dynamics." Led by its visionary CEO, Emily, Phoenix Dynamics was on the cusp of exponential growth. However, beneath the surface, a crisis brewed. Disengagement among employees, dwindling innovation, and a disconnect from the company's mission threatened to halt progress.

Recognizing the urgency to rekindle the company's spirit, Emily embarked on a mission to reignite the flames of passion and purpose within her workforce. She understood that a belief system was not just a collection of buzzwords but a living, breathing entity that needed nurturing.

Emily gathered her team in a town hall meeting. She didn't merely present new goals or strategies. Instead, she shared her personal journey, highlighting the values that had guided her. Vulnerable and authentic, she laid bare the importance of belief in fostering unity, resilience, and progress.

The first pillar of Phoenix Dynamics' revamped belief system emerged: transparency and authenticity. Emily encouraged open dialogue, welcoming diverse perspectives and fostering an environment where honesty was valued above all.

However, a belief system is not built overnight. Emily knew that actions spoke louder than words. To embed the values into the company's DNA, she initiated a series of workshops, encouraging employees to reflect on their personal values and how they aligned with the company's mission.

Slowly but surely, the second pillar, alignment and cohesion, took shape. Teams began to identify shared values and goals, creating a unified vision that transcended individual objectives.

As months passed, Emily observed a remarkable transformation. The once-disengaged employees became advocates of change, driving innovation and collaboration. They were empowered by the belief system that guided their actions, decisions, and interactions.

The third and final pillar, empowerment and ownership, solidified. Employees felt a sense of ownership over the company's mission, understanding that their contributions mattered and were aligned with the overarching purpose.

The result? Phoenix Dynamics soared to new heights. Productivity surged, creativity blossomed, and a sense of community permeated every corner of the organization. Clients noticed the shift, recognizing the genuine passion and dedication behind the company's products and services.

=============================

This story of Phoenix Dynamics encapsulates the transformative potential of a robust belief system in organizational leadership. It's not merely a set of values inscribed on walls or printed in handbooks; it's a living, evolving entity that requires continuous nurturing and commitment.

In today's rapidly evolving business landscape, where change is the only constant, a strong belief system acts as a guiding light. It provides stability, fosters resilience, and unites diverse individuals toward a common goal.

Ultimately, it's the leaders who understand the significance of cultivating and embodying these values who pave the way for organizational success—where belief isn't just a word but a way of life.

Unveiling the Power of Value in Value Stream Mapping

In the dynamic landscape of process optimization and efficiency enhancement, the concept of 'value' stands tall as the cornerstone of success. Within this realm, one of the most potent tools that businesses employ is Value Stream Mapping (VSM). At its core, VSM is a visual representation of the steps involved in delivering a product or service to a customer, allowing organizations to identify waste, streamline processes, and ultimately enhance value delivery.

Understanding Value in Value Stream Mapping

Value, in the context of VSM, is defined by the customer. It's what the customer is willing to pay for and what enhances the quality, functionality, or purpose of the end product or service. Everything else within the process that doesn't directly contribute to this perceived value is considered waste.

This concept is fundamental in dissecting and understanding each step of the value stream. It enables organizations to differentiate between activities that add value and those that are non-value adding or, worse, contribute to inefficiencies.

Identifying Value-Adding Activities

When creating a value stream map, pinpointing value-adding activities is pivotal. These are the actions, transformations, or contributions that directly shape the product or service into something the customer desires. They represent the essence of the process, the core actions that customers are willing to pay for.

For instance, in manufacturing, value-adding activities might include assembly, customization, or fabrication steps. In service industries, it could be tasks that directly fulfill customer requests or enhance the overall experience.

Confronting Non-Value Adding Elements

However, not all actions within a process add value. Non-value adding activities, often deemed as waste, are steps or operations that do not contribute to the final product or service in the customer's eyes. These can include unnecessary movements, overproduction, excessive waiting times, or redundant approvals.

Unearthing and addressing these non-value adding elements is where the true prowess of VSM shines. By eliminating or minimizing waste, organizations can optimize their processes, reduce costs, and enhance overall efficiency.

Enhancing Value through Streamlining

Value Stream Mapping is not solely about identifying the good and the bad; it's about transforming processes to maximize value. Once waste is recognized, strategies can be devised to eliminate it. This might involve rearranging the sequence of operations, reducing wait times, or implementing automation to streamline the workflow.

By systematically eradicating waste and focusing efforts on value-adding tasks, organizations can bolster their competitive edge, responding more adeptly to customer demands while operating at peak efficiency.

Continuous Improvement: The Essence of Value

The concept of value in Value Stream Mapping isn't stagnant; it's perpetually evolving. As customer needs change, so must the definition of value. Thus, VSM becomes a continuous improvement journey rather than a one-time fix.

Regularly revisiting and refining the value stream map ensures that businesses stay aligned with customer expectations and market trends. It fosters a culture of adaptability and innovation, empowering organizations to consistently deliver maximum value.

Conclusion

Value Stream Mapping is not merely a tool; it's a philosophy that champions the quest for value. By comprehensively understanding what constitutes value, businesses can optimize their operations, reduce waste, and most importantly, deliver exceptional products and services that resonate with their customers.

In essence, value, when intricately woven into the fabric of Value Stream Mapping, becomes the guiding beacon steering businesses toward efficiency, sustainability, and unwavering customer satisfaction.
