AI governance has transformed trust and security while human oversight remains focused and minimal
In a recent project and task, I showcase how we use Fiddler AI's key features like AI observability and monitoring, which track hundreds of metrics across traditional machine learning models and large language models to monitor performance, data drift, and accuracy. We use it as security and guardrails that implement real-time safety measures to block harmful outputs and protect against jailbreak and prompt injection attempts. We also utilize it for explainability, helping teams understand why an AI model made a specific prediction or decision, providing deep root cause analysis when problems occur. Lastly, we employ it for governance and compliance, creating centralized audit trails and model cards to help companies meet strict regulatory standards and risk management requirements. Fiddler AI has significantly impacted my organization positively, particularly in security and guardrails. As we use many tools, we previously had humans monitoring all of them. Human errors created loopholes, but now with Fiddler AI, which is trained using our company policies and playbooks, human intervention has become minimal. We have reduced human intervention by 70% and human mistakes by around 90%, which are the points I wanted to mention. Reducing human intervention by 70% directly affects our productivity and day-to-day work. A person who worked with one policy or guardrail for a week now hardly takes one day, saving us six days of effort for each cycle. Moreover, the reduction in human mistakes has significantly improved product quality, with great feedback from vendors and other businesses using the product, increasing confidence levels and scores when using Fiddler AI.

Have improved machine learning model automation and reduced decision-making time
One improvement I would like to see in H2O.ai is regarding the integration capabilities with different data sources, as I've seen platforms like DataIQ and DataBricks offer great integration with various data sources. H2O.ai could benefit from enhanced integration with real-time versus offline data sources, as well as improvements in productionalization solutions, including better deployment options on platforms like Azure and CI/CD integration. One of the features I'd like to see included in upcoming releases of H2O.ai pertains to the growing trend of Generative AI, with applications for LLM-based models and vector databases. I would like to see a solution similar to Azure AI Foundry, which provides the flexibility to integrate different LLMs into applications, including H2O-GPT and other models for varied applications.

Pros

"All features in Fiddler AI are good, offering excellent connectivity options."
"Reducing human intervention by 70% directly affects our productivity and day-to-day work, as a person who worked with one policy or guardrail for a week now hardly takes one day, saving us six days of effort for each cycle, and the reduction in human mistakes has significantly improved product quality, with great feedback from vendors and other businesses using the product, increasing confidence levels and scores when using Fiddler AI."
"Since I started using Fiddler AI, it improved my technical expertise about the understanding of logs, bugs, sessions, and traffic, and how to control the request and response."
"Over time, it has become part of our regular workflow whenever we need to check the model health or investigate unexpected behavior."
"Fiddler AI is the best solution in the market to analyze the QSR domain."
"H2O.ai provides better flexibility where I could examine more models and obtain results, and based on these results, I could make the next set of decisions."
"The company is interested in using an external platform in order to have an updated environment."
"AutoML helps in hands-free initial evaluations of efficiency/accuracy of ML algorithms."
"The most valuable feature of H2O.ai is that it is plug-and-play."
"I have utilized the AutoML feature in H2O.ai, which is one of the very powerful features where you don't need to worry about which algorithm is best for your model."
"It is helpful, intuitive, and easy to use. The learning curve is not too steep."
"One of the most interesting features of the product is their driverless component, which allows you to test several different algorithms along with navigating you through choosing the best algorithm and gives you an interpretability capability that allows you to have some understanding of what's inside the algorithm and why it's behaving a certain way, making sure you are not biased towards the outcome."
"The product is definitely worth looking at, as it is one of the upcoming products where you can build large models for use cases."
 

Cons

"Sometimes Fiddler AI's UI is a bit more complicated because the options sometimes feel confusing when you open the tabs and sub-tabs."
"The main thing I would improve with Fiddler AI is onboarding and ease of use for different stakeholders."
"When explaining a product, it is essential to specify company policies and guardrails. Without providing company-specific criteria, the product may hallucinate, as it will compare international policy boards with our company's policies."
"One improvement I would like to see in H2O.ai is regarding the integration capabilities with different data sources, as I've seen platforms like DataIQ and DataBricks offer great integration with various data sources."
"Feature engineering."
"H2O.ai can improve in areas like multimodal support and prompt engineering."
"The interpretability module has room for improvement. Also, it needs to improve its ability to integrate with other systems, like SageMaker, and the overall integration capability."
"It needs a drag and drop GUI like KNIME, for easy access to and visibility of workflows."
"It lacks the data manipulation capabilities of R and Pandas DataFrames. We would kill for dplyr offloading H2O."
"Regarding documentation, I faced challenges as I didn't see much information from a documentation perspective."
"I would like to see more features related to deployment."
