In many organisations, Chief Data and Analytics Officers (CDAOs) find their roles confined to traditional data management tasks, mirroring the responsibilities typically associated with Chief Data Officers (CDOs). Their focus often centres on governance, compliance, and platform investments — essential areas, but ones that risk overshadowing their ability to deliver strategic business value through analytics.

In 2023, the field of generative artificial intelligence (AI) experienced remarkable progress, with significant advancements in natural language processing, computer vision, and audio synthesis. These developments have unlocked a plethora of new opportunities and applications, shaping the future trajectory of technology across a wide range of sectors. This article provides an overview of the ethical considerations and responsible strategies for the development, deployment, an

Generative AI is a branch of artificial intelligence that focuses on creating new content or data from scratch, such as images, text, music, code, diagrams, etc. Generative AI has been making impressive advances in recent years, thanks to the development of deep learning models such as generative adversarial networks (GANs), autoencoders, transformers, and others.

A Large Language Model (LLM) is a notable AI system, powered by neural networks, designed to comprehend and generate human-like text from vast amounts of training data. These models are like language virtuosos, capable of matching context, generating coherent text, and answering questions in a way that seems human. They have gained significant attention due to their potential applications in chatbots, content generation, language translation, and information retrieval. Origin

Once businesses have started collecting and combining all kinds of data, the next elusive step is to extract value from it. Collected data may hold tremendous potential, but no value can be created unless insights are uncovered and translated into actions or business outcomes.

I have seen many articles on types of analysis. Most of these articles discuss four types: descriptive, exploratory, diagnostic (usually either exploratory or diagnostic!), predictive, and prescriptive analysis. But throughout my early career, I’ve personally experienced eight types of analysis. I encourage all aspiring data scientists to be familiarised with all these types of analysis and, if necessary, apply them. Originally published at LinkedIn Pulse on 22 December 2019

Generative AI (GenAI), especially LLMs, has transitioned from a buzzword to an essential business asset. Leading organisations have moved beyond the proof-of-concept (POC) phase and are now actively deploying GenAI solutions. Many non-technology companies have realised that developing proprietary LLMs is unnecessary for solving internal challenges . Instead, they acquire LLMs from vendors or the open-source marketplace.

In today’s data-driven landscape, CDO, CAO, and CDAO are critical in steering organisations towards success. The journey began with the CDO, who introduced a data-centric culture by developing robust data strategies, ensuring data governance, and effectively managing data assets. As the volume and complexity of data grew, the need for specialised analytics expertise became apparent, leading to the creation of the CAO role. The CAO focused on transforming raw data into actiona

Over the past two decades, I’ve used analytics to support decision-making across nearly every part of enterprises. Yet, I’ve never once built a dashboard. They’ve consistently failed to deliver the insight and agility needed for real-world decisions. Dashboards demand a fixed set of questions and perfectly cleaned data up front, take months to build, and quickly become obsolete. In practice, they trap insight in rigid charts, leaving users to scroll through stale reports inst

Hallucination in Large Language Models (LLMs) refers to the generation of content that may deviate from factual accuracy or the provided source content. While these instances may occur, it’s crucial to recognise that LLMs are primarily designed for general-purpose language understanding and generation, not for delivering absolute precision.

When I embarked on my first data role over a decade ago, my organisation was supported by a team of 30 business analysts responsible for generating insight reports by extracting a month’s worth of transaction data from an Oracle database, conducting analysis, creating visualisations, and documenting observed trends. They used a custom web interface with different parameters to extract the data from the database. Unfortunately, this entire process, from start to finish, took a

To drive value from data, analytics need to be operationalised. Ad-hoc data exploration can be unclear, depends on each individual functional team’s preferences to generate insight, acted on and then forgotten under the pile of documentation. The preference may vary from the way the experiments are conducted, tools being used, and the finding has been disseminated. Every project starts from scratch. And if someone with a vast knowledge leaves the organisation, the prior knowl

In the modern business landscape, the utilisation of data and analytics has transcended its conventional role of providing retrospective insights and has emerged as a catalytic force for driving meaningful impact across organisations. This article explores the concept of transformative analytics, delving into its significance, challenges, and strategies while shedding light on real-world instances of organisations that have successfully harnessed analytics to bring about prof

Multiple recent recruitment surveys revealed that the demand for data engineers has recently exceeded the previous demand for data scientists. The Dice 2020 Tech Job Report said data engineer was the fastest growing job in technology with a 50% year-over-year growth in the number of open positions. Many mentees asked me how do I perceive this shifts in demand, and what area should they pursue. Actually, I see a course correction happening in the industry. Most organisations t

With the advent of the data science practises, especially the likes of Artificial Intelligence (AI) or machine learning and their adaptation in sensitive areas, has drawn massive attention to this technology in the recent years. Whether it is cancer diagnosing system, Amazon’s AI recruiting tool or the US court’s profiling system Correctional Offender Management Profiling for Alternative Sanctions (COMPAS), we can always disagree to the decision made by the AI systems.
