Robot Scribes: Reliability and Trust in AI-Generated Meeting Minutes

March 15, 2024

Introduction

Meetings are an unavoidable aspect of the modern workplace. They serve as forums for discussion, coordination, and problem-solving. However, they also come with the often tedious task of documenting decisions, key points, and action items. Traditional methods of manual note-taking are rife with potential for errors, omissions, and are substantially time consuming, which may detract from full engagement in the meeting itself. AI-generated meeting speech to text can be considered as a potentially game-changing approach to automating the transcription process. Many meetings applications such as Microsoft Teams, Slack, and Google Meet use automatic captioning, which can be recorded and used, instead of going through the entire video once again, thus saving time.

‍

AI assisted meeting systems claim to provide an effortless way to obtain meeting transcripts by using advancements in Natural Language Processing (NLP) and the flexible computing power of cloud GPU services. The concept was first seen by the general public in Youtube, when videos started getting auto generated closed captioning. Even though the concept has been available in the market for a few years, it is still alluring, freeing up time and ensuring a more complete meeting record. But can we realistically place unwavering trust in the accuracy and usefulness of such AI-generated output? It is rather difficult to answer this question, due to the technical complexities involved.

This blog takes a look at AI-generated meeting minutes and live captions. We'll discuss the inner workings driving the reliability (or lack thereof) in these emerging tools and explore strategies to use greater transparency and provide actionable guidance for users to responsibly evaluate AI-generated minutes. It is crucial to transcend hype and achieve a clear view of how AI can meaningfully improve, or replace the conventional methods of capturing meeting content.

Technical Foundations

AI-generated meeting minutes rest on several pillars of NLP. At the core lies speech recognition, converting spoken words into text. These systems depend on models that are ‘trained’ by being exposed to massive datasets of audio recordings and their corresponding text transcripts. To further understand the meeting's flow, techniques like summarization and topic modeling might be used, though these applications are less mature than simple speech-to-text conversion.

The success of this process directly depends on several factors. Clear audio with minimal background noise is crucial for the AI to pick up words correctly. If the system lacks training on domain-specific vocabulary (like terms within medicine, finance, or engineering), it will struggle to accurately transcribe the discussions. Diverse speech patterns, including accents, regional dialects, and fast speakers, further challenge the AI's recognition capabilities.

Additionally, most AI meeting scribes are designed with a single language in mind. Meetings conducted in multiple languages or where participants frequently switch between languages lead to a significant drop in transcription accuracy. Eg. in MS Teams, if auto captioning is turned on, only one language is selected, which can be set in the settings or changed during each meeting. But it does not support multiple languages within the same meeting.

‍

The complex processes involved in audio processing, training NLP models, and generating live captions or meeting minutes require significant computational resources. Cloud GPUs are largely required for this. Equipped with hundreds or even thousands of cores, they are highly adept at the parallel calculations required for NLP tasks. Additionally, cloud services such as E2E Cloud let organizations access powerful GPUs without large upfront investment, enabling on-demand scalability as meeting transcription needs change.

Reliability Challenges

While the actual technologies offer undeniable potential, putting them into real-world practice uncovers critical challenges to the full reliability of AI-generated meeting minutes.

Accuracy Limitations: Even in ideal recording conditions, cutting-edge AI models remain prone to occasional transcription errors. Challenges persist with homonyms (words like 'there,' 'their,' and 'they're'), proper names without established spellings, and discussions saturated with complex technical terminology. While individual mistakes might seem trivial, they can cumulatively undermine the overall clarity and trustworthiness of the generated meeting minutes.
Contextual Nuances: Human conversations are complex and involve more than just the words that are spoken. AI systems have limitations when it comes to understanding implied meanings, sarcasm, humor, and the nuances involved in reaching decisions. Relying solely on AI-generated minutes as a precise and undisputed record of what occurred can lead to problems due to the current limitations of this technology. Therefore, it is important to recognize these limitations and not place too much trust in AI's current capabilities when it comes to accurately capturing the intricacies of human conversation.
Bias Awareness: NLP models, which are commonly utilized in meeting transcription tools, have the potential to embed implicit biases based on race, gender, accents and socioeconomic factors. This is because these systems are trained on massive datasets that may contain skewed or incomplete information. As a result, the accuracy of these models can vary significantly with certain speakers' words being frequently misinterpreted. In situations where sensitivity is of utmost importance such as performance reviews or HR-related meetings, unexamined AI output could perpetuate problematic attitudes and reinforce social injustices without anyone realizing it. Therefore, it is crucial to implement rigorous checks and balances to ensure that NLP models do not contribute to furthering social disparities and prejudices.

Although the notion of accurate and all-inclusive AI transcription of meetings may appear attractive, the reality is far from it. It is crucial to recognize these constraints in order to make well-informed choices. Developers can strive towards creating bespoke solutions that tackle probable problems, while users ought to approach AI-generated meeting minutes with a wary outlook. By doing so, we can guarantee that the utilization of AI in this domain is both responsible and efficient.

Trust-Building Strategies

Acknowledging the reliability challenges involved in AI-generated meeting minutes shouldn't lead to the complete dismissal of their value. Developers and users alike can take proactive steps to increase trust in these emerging tools. Strategies focus on transparency, user empowerment, maintaining robust human oversight, and responsible data stewardship.

Transparency: It is crucial for developers to provide clear insight into the capabilities and limitations of their AI meeting transcription systems. Rather than generic accuracy claims, offering more granular metrics (e.g., accuracy scores against benchmark datasets) adds valuable context. Disclosing known biases and how the systems perform in multilingual situations helps user awareness, increasing trust and setting realistic expectations.
Customer Feedback: The interface can greatly impact how effectively users interact with the output. Enabling intuitive ways for users to flag questionable transcription segments directly allows for immediate feedback to developers for continuous model improvement.
Human Oversight: It is critical to establish a mindset where AI provides a helpful starting point, not an absolute final product. Organizations need clear protocols for how thoroughly AI-generated transcripts should be reviewed before distribution or internal use. However this would not be possible for most cases since they may not have time to review the minutes of meeting, which defeats its very purpose. In case of live transcripts, proofreading is not possible since it must be shown in real time.

A combination of clear, transparent technology, coupled with conscious usage patterns that incorporate human judgment, leads to the adoption of this time-saving technology without sacrificing accuracy or creating new biases.

The Evolving Landscape

AI-powered meeting transcription is a rapidly developing field. Here's a glimpse at current research directions and trends that promise to further improve the reliability and trustworthiness of these systems:

Multimodal AI: While current tools primarily focus on speech-to-text, next-generation systems may combine multiple modalities. The understanding of meetings could be enhanced by incorporating insights from visuals (facial expressions, presentation slides) or additional environmental data. Such integration is still in its infancy, but holds potential.
Summarization: Many meetings end up longer than they needed to be. Emerging research centers on AI that can identify key discussion points, action items, and decisions from lengthy meetings, creating succinct summaries to save time. While this is already possible by different LLMs, they are not present in most AI scribes or transcript generators. This integration can be easily implemented by the companies.
Bias Mitigation: Developers are actively investigating techniques to detect and minimize biases that can creep into AI meeting scribes. These approaches involve carefully curating training datasets, developing more inclusive language models, and allowing users to provide feedback on instances of bias within the tool itself.

Continuous research and development in the field of AI has brought about significant improvements in both accuracy and nuance, making it possible for meeting scribes to capture detailed information with greater precision. It is important to stay up-to-date with emerging trends in this dynamic field, as this will inform best practices in the future and ensure that all stakeholders are able to benefit from the latest advances. With ongoing advancements in AI technology, there is no doubt that we can expect even more exciting developments in the years ahead.

IT Considerations and Meeting Optimization

Meeting scribes hold the promise of streamlined communication and increased productivity. But achieving that in real-world organizational settings comes with complexities. This section addresses those challenges, offering guidance for IT departments and anyone hoping to move beyond a mindset of simply wanting an 'AI notetaker.'

Meeting transcripts often contain sensitive information, ranging from financial details to proprietary R&D discussions. IT security professionals face unique challenges when choosing cloud-based transcription services. Strict controls around data retention periods, encryption both at rest and in transit, and ensuring robust auditing capabilities become non-negotiable. Existing enterprise privacy compliance needs careful alignment with transcription solutions. This could mean investigating services committed to SOC 2 and HIPAA compliance and exploring tools specifically tailored to regulated industries (healthcare, finance).

For many organizations, the scalability and ease of integration make cloud-based AI meeting scribes highly appealing. However, there are certain scenarios where on-premise solutions provide greater peace of mind, despite initial deployment complexity and potentially higher costs. High-stakes meetings where absolute confidentiality is critical, along with industries subject to strict data sovereignty regulations, might favor on-premise options. The ability to fully control where and how meeting data is stored can outweigh the flexibility promised by cloud services.

As AI-transcription becomes common practice, a further level of sophistication awaits: utilizing these tools to improve the meeting quality itself. These are still emergent approaches, but the potential is significant. Analyzing patterns across transcripts could aid in identifying traces of inefficient meetings such as rambling discussions, leading to actionable productivity feedback.

Advanced tools of the future may surpass mere event recording capabilities. It is conceivable that proactive guidance during meetings could become a reality. Such systems could prompt users when agreement has been reached, tactfully signal topics straying from the agenda, or even notify when one participant monopolizes discussion time. These attributes subtly transform AI into an active agent for optimal meeting dynamics.

Conclusion

While AI-generated meeting minutes offer undeniable potential for enhancing productivity and record-keeping, it's crucial to navigate this developing technology with a discerning eye. The trustworthiness of these AI-powered tools remains the most significant factor determining their widespread adoption. As AI models become more sophisticated, the reliability of both saved meeting minutes and live transcriptions undoubtedly increases. However, for mission-critical discussions where precision is paramount, meticulous human review remains a necessary safeguard.

The most prudent approach likely involves a collaborative workflow between AI and human oversight. AI can generate the initial meeting summary, highlighting key decisions and action items, while a human editor thoroughly reviews the output to ensure accuracy and address subtle nuances. However this would not be possible for most cases since they may not have time to review the minutes of meeting, which defeats its very purpose. In case of live transcripts, proofreading is not possible since it must be shown in real time.

To accelerate reliability, future development should prioritize training AI models on diverse datasets, enhancing their ability to manage variations in speech patterns and accents. Additionally, advancements in AI error detection could lead to automated flagging of potentially inaccurate sections for streamlined review. To explore how AI-powered solutions can transform your meeting processes, you can build your own NLP models using existing online resources. Utilize the high end and cost-effective GPUs available from E2E Cloud. Both NVIDIA H100 and L40s GPUs are suitable for NLP applications.

Image-based 3D Object Reconstruction State-of-the-Art and trends in the Deep Learning Era

3D reconstruction is one of the most complex issues of deep learning systems. There have been multiple types of research in this field, and almost everything has been tried on it — computer vision, computer graphics and machine learning, but to no avail. However, that has resulted in CNN or convolutional neural networks foraying into this field, which has yielded some success.

The Main Objective of the 3D Object Reconstruction

Developing this deep learning technology aims to infer the shape of 3D objects from 2D images. So, to conduct the experiment, you need the following:

Highly calibrated cameras that take a photograph of the image from various angles.
Large training datasets can predict the geometry of the object whose 3D image reconstruction needs to be done. These datasets can be collected from a database of images, or they can be collected and sampled from a video.

By using the apparatus and datasets, you will be able to proceed with the 3D reconstruction from 2D datasets.

State-of-the-art Technology Used by the Datasets for the Reconstruction of 3D Objects

The technology used for this purpose needs to stick to the following parameters:

Input

Training with the help of one or multiple RGB images, where the segmentation of the 3D ground truth needs to be done. It could be one image, multiple images or even a video stream.

The testing will also be done on the same parameters, which will also help to create a uniform, cluttered background, or both.

Output

The volumetric output will be done in both high and low resolution, and the surface output will be generated through parameterisation, template deformation and point cloud. Moreover, the direct and intermediate outputs will be calculated this way.

Network architecture used

The architecture used in training is 3D-VAE-GAN, which has an encoder and a decoder, with TL-Net and conditional GAN. At the same time, the testing architecture is 3D-VAE, which has an encoder and a decoder.

Training used

The degree of supervision used in 2D vs 3D supervision, weak supervision along with loss functions have to be included in this system. The training procedure is adversarial training with joint 2D and 3D embeddings. Also, the network architecture is extremely important for the speed and processing quality of the output images.

Practical applications and use cases

Volumetric representations and surface representations can do the reconstruction. Powerful computer systems need to be used for reconstruction.

Given below are some of the places where 3D Object Reconstruction Deep Learning Systems are used:

3D reconstruction technology can be used in the Police Department for drawing the faces of criminals whose images have been procured from a crime site where their faces are not completely revealed.
It can be used for re-modelling ruins at ancient architectural sites. The rubble or the debris stubs of structures can be used to recreate the entire building structure and get an idea of how it looked in the past.
They can be used in plastic surgery where the organs, face, limbs or any other portion of the body has been damaged and needs to be rebuilt.
It can be used in airport security, where concealed shapes can be used for guessing whether a person is armed or is carrying explosives or not.
It can also help in completing DNA sequences.

So, if you are planning to implement this technology, then you can rent the required infrastructure from E2E Networks and avoid investing in it. And if you plan to learn more about such topics, then keep a tab on the blog section of the website.

A Comprehensive Guide To Deep Q-Learning For Data Science Enthusiasts

For all data science enthusiasts who would love to dig deep, we have composed a write-up about Q-Learning specifically for you all. Deep Q-Learning and Reinforcement learning (RL) are extremely popular these days. These two data science methodologies use Python libraries like TensorFlow 2 and openAI’s Gym environment.

So, read on to know more.

What is Deep Q-Learning?

Deep Q-Learning utilizes the principles of Q-learning, but instead of using the Q-table, it uses the neural network. The algorithm of deep Q-Learning uses the states as input and the optimal Q-value of every action possible as the output. The agent gathers and stores all the previous experiences in the memory of the trained tuple in the following order:

State> Next state> Action> Reward

The neural network training stability increases using a random batch of previous data by using the experience replay. Experience replay also means the previous experiences stocking, and the target network uses it for training and calculation of the Q-network and the predicted Q-Value. This neural network uses openAI Gym, which is provided by taxi-v3 environments.

Now, any understanding of Deep Q-Learning is incomplete without talking about Reinforcement Learning.

What is Reinforcement Learning?

Reinforcement is a subsection of ML. This part of ML is related to the action in which an environmental agent participates in a reward-based system and uses Reinforcement Learning to maximize the rewards. Reinforcement Learning is a different technique from unsupervised learning or supervised learning because it does not require a supervised input/output pair. The number of corrections is also less, so it is a highly efficient technique.

Now, the understanding of reinforcement learning is incomplete without knowing about Markov Decision Process (MDP). MDP is involved with each state that has been presented in the results of the environment, derived from the state previously there. The information which composes both states is gathered and transferred to the decision process. The task of the chosen agent is to maximize the awards. The MDP optimizes the actions and helps construct the optimal policy.

For developing the MDP, you need to follow the Q-Learning Algorithm, which is an extremely important part of data science and machine learning.

What is Q-Learning Algorithm?

The process of Q-Learning is important for understanding the data from scratch. It involves defining the parameters, choosing the actions from the current state and also choosing the actions from the previous state and then developing a Q-table for maximizing the results or output rewards.

The 4 steps that are involved in Q-Learning:

Initializing parameters – The RL (reinforcement learning) model learns the set of actions that the agent requires in the state, environment and time.
Identifying current state – The model stores the prior records for optimal action definition for maximizing the results. For acting in the present state, the state needs to be identified and perform an action combination for it.
Choosing the optimal action set and gaining the relevant experience – A Q-table is generated from the data with a set of specific states and actions, and the weight of this data is calculated for updating the Q-Table to the following step.
Updating Q-table rewards and next state determination – After the relevant experience is gained and agents start getting environmental records. The reward amplitude helps to present the subsequent step.

In case the Q-table size is huge, then the generation of the model is a time-consuming process. This situation requires Deep Q-learning.

Hopefully, this write-up has provided an outline of Deep Q-Learning and its related concepts. If you wish to learn more about such topics, then keep a tab on the blog section of the E2E Networks website.

GAUDI: A Neural Architect for Immersive 3D Scene Generation

The evolution of artificial intelligence in the past decade has been staggering, and now the focus is shifting towards AI and ML systems to understand and generate 3D spaces. As a result, there has been extensive research on manipulating 3D generative models. In this regard, Apple’s AI and ML scientists have developed GAUDI, a method specifically for this job.

An introduction to GAUDI

The GAUDI 3D immersive technique founders named it after the famous architect Antoni Gaudi. This AI model takes the help of a camera pose decoder, which enables it to guess the possible camera angles of a scene. Hence, the decoder then makes it possible to predict the 3D canvas from almost every angle.

What does GAUDI do?

GAUDI can perform multiple functions –

The extensions of these generative models have a tremendous effect on ML and computer vision. Pragmatically, such models are highly useful. They are applied in model-based reinforcement learning and planning world models, SLAM is s, or 3D content creation.
Generative modelling for 3D objects has been used for generating scenes using graf, pigan, and gsn, which incorporate a GAN (Generative Adversarial Network). The generator codes radiance fields exclusively. Using the 3D space in the scene along with the camera pose generates the 3D image from that point. This point has a density scalar and RGB value for that specific point in 3D space. This can be done from a 2D camera view. It does this by imposing 3D datasets on those 2D shots. It isolates various objects and scenes and combines them to render a new scene altogether.
GAUDI also removes GANs pathologies like mode collapse and improved GAN.
GAUDI also uses this to train data on a canonical coordinate system. You can compare it by looking at the trajectory of the scenes.

How is GAUDI applied to the content?

The steps of application for GAUDI have been given below:

Each trajectory is created, which consists of a sequence of posed images (These images are from a 3D scene) encoded into a latent representation. This representation which has a radiance field or what we refer to as the 3D scene and the camera path is created in a disentangled way. The results are interpreted as free parameters. The problem is optimized by and formulation of a reconstruction objective.
This simple training process is then scaled to trajectories, thousands of them creating a large number of views. The model samples the radiance fields totally from the previous distribution that the model has learned.
The scenes are thus synthesized by interpolation within the hidden space.
The scaling of 3D scenes generates many scenes that contain thousands of images. During training, there is no issue related to canonical orientation or mode collapse.
A novel de-noising optimization technique is used to find hidden representations that collaborate in modelling the camera poses and the radiance field to create multiple datasets with state-of-the-art performance in generating 3D scenes by building a setup that uses images and text.

To conclude, GAUDI has more capabilities and can also be used for sampling various images and video datasets. Furthermore, this will make a foray into AR (augmented reality) and VR (virtual reality). With GAUDI in hand, the sky is only the limit in the field of media creation. So, if you enjoy reading about the latest development in the field of AI and ML, then keep a tab on the blog section of the E2E Networks website.
