Raising $100 million to fund open and collaborative machine learning projects is a significant achievement. This investment highlights the potential of the field and the commitment of the organizations involved to accelerate development of machine learning applications. At the same time, this investment also comes with a number of significant challenges.

This introductory article will explore these challenges and how they can be addressed.

We Raised $100 Million for Open & Collaborative Machine Learning

Open and collaborative machine learning (OCML) is an innovative approach that enables the development of artificial intelligence technologies more openly. This approach combines both open source software and collaboration between humans to create a powerful platform for creating technology solutions.

OCML encourages the creation of large-scale data sets and making them available to anyone who wants to use them. Many people can compile data from multiple sources, analyze it and discover patterns. This collective effort can help create better models faster—in traditional machine learning, data collection process is time-consuming and often frustrating since it is done primarily by companies or individual researchers who have limited access to resources. By eliminating the need for centralized control, OCML makes data collection and analysis much easier.

Along with allowing collective work, OCML fosters an environment for experimentation for further refinement of AI algorithms by supporting diverse ideas from different researchers to determine which ones are effective in solving real world problems. In this way, OCML helps create better models much faster than the traditional approach which usually relies on single researcher’s independent work over long period. It provides an environment that allows for much quicker exploration and innovation resulting in advances in AI technologies that would otherwise be difficult or impossible to make with traditional approaches alone.

The need for open and collaborative machine learning

In recent years, the demand for cloud-based machine learning (ML) solutions has drastically increased as organizations move toward digital transformation and strive to leverage the growing amounts of data available. As more businesses explore ML solutions and algorithms, they face the challenges of ML deployment at scale, from provisioning hardware and software to creating a platform for data management. Furthermore, there is a need to ensure that data is secure and compliant with applicable regulations.

The trend of open source platforms can be seen in all types of industries, from retail to telecom to financial services as customers increasingly require open systems that can be adapted to meet changing demands. Additionally, open source solutions often provide access to a greater diversity of expertise than closed systems for tackling complex problems like creating machine learning models or improving accuracy and precision in predictions.

Collaborative machine learning is essential in this era of rapidly evolving technology where the combination of diverse team members’ perspectives can yield outcomes that cannot be achieved by any one individual alone. By leveraging collaborative techniques such as algorithms, knowledge sharing tools and deep dives into data sets across distributed teams, organizations can more effectively find information-rich solutions while minimizing cost, improving efficiency and reducing risk.


The recent surge in open & collaborative machine learning has been a boon for data scientists, investors and companies. With over $100 million raised for open and collaborative machine learning projects, the potential for innovation and collaboration is immense.

However, several challenges come with open & collaborative machine learning projects. In this article, we will discuss some of these challenges and how to address them.

Data privacy and security

Data privacy and security are some of the most difficult challenges surrounding open and collaborative machine learning. Data access control is essential to ensure that data is only used for authorized purposes and handled securely. If a company or organization wants to expand its collaboration with partners, ensuring that the shared data remains secure is paramount. As such, organizations must apply best practices related to authentication, authorization, encryption, scrubbing, anomaly detection, access control, and other such IT measures to safeguard their data assets appropriately.

Organizations must also be aware of laws governing access and usage of sensitive personal or corporate information in their open and collaborative projects. For example, the European Union’s General Data Protection Regulation (GDPR) mandates that users explicitly provide consent before their data can be used in any system. Organizations need to be mindful of these regulations when collecting userdata for use in machine learning models. Additionally, organizations must devise clear policies outlining which partners will gain access to the shared datasets and under which conditions this data may be accessed or modified.

Lack of trust and transparency

To increase trust and transparency in open and collaborative machine learning, organizations need to foster a culture of shared learning. Organizations must take proactive steps to ensure the data used for training models is accurate and representative of the population that the model is trying to target. This means properly collecting, curating and sharing data related to model accuracy and fairness.

Additionally, organizations should provide clear policies for how models are developed and maintained to ensure that efforts are well-coordinated, objectives are measurable and progress is visible.

Organizations should also strive for an open communication strategy which includes multiple channels where users can ask questions, make suggestions or voice their concerns about the development or upkeep of machine learning models. This would help stakeholders gain a better understanding of what works well in certain use cases versus others, be able to assess potential risks associated with models that have not been fully tested, as well as providing feedback on an ongoing basis and making sure that everyone’s opinions are heard throughout all stages of development.

Finally, organizations should be transparent with their customers regarding data collection; they should explain why certain sources or datasets have been chosen over others and assure users that their privacy will be protected whenever data is collected for model training purposes.

Data interoperability

Data interoperability is one of the main challenges in open and collaborative machine learning that must be addressed to realize its potential. Data interoperability refers to the ability of data and/or systems to communicate regardless of their platforms, formats and types.

Open and collaborative machine learning aims to leverage the most suitable datasets from multiple external sources, which inherently means all these different datasets must be interoperable. In addition, data shared within a collaborative environment is likely to take on different forms throughout its lifetime (e.g., structured, unstructured, relational, static). This requires advanced technologies to help bridge gaps between datasets in format or structure.

The challenges posed by data interoperability can be effectively addressed by:

1) developing standardized protocols and interfaces;

2) developing techniques for automating the transfer of data between different formats;

3) implementing appropriate methods for representing context and structures associated with distributed information sharing (such as metadata);

4) creating tools that can map authoring models over heterogeneous datasets;

5) developing systems capable of discovering relationships among entities across many heterogeneous datasets;

6) implementing security measures so that data remains safe during the integration process;

7) using semantic technologies (such as natural language processing, ontologies, etc.) to help extract meaning in open sources of information;

8 ) looking into self-describing message formats such as JSON or XML as well as self-describing APIs;

9) examining AI/ML methods such as neural networks to learn complex network dynamics and infer relations between correlated variables distributed within multiple datasets.

Data quality

The challenges of open and collaborative machine learning are many. One of the main issues is data quality, which is essential for producing high-quality machine learning models. It can be difficult to acquire reliable, genuine data from open sources due to privacy concerns and other challenges with crowdsourcing data. Additionally, poorly labeled data can lead to incorrect assumptions and reduced performance.

An approach that uses established procedures such as maintaining an anonymization level and providing necessary clarity is key in acquiring quality data. Ensuring the right questions are asked when collecting feedback is just as important so that reliable insights are achieved. Using APIs or controlled methods is also helpful in preventing malicious users from sabotaging data quality or results.


Scalability is one of the most significant challenges of open and collaborative machine learning. Many and varied challenges arise when attempting to scale up open machine learning solutions.

One challenge is ensuring optimal resource utilization and energy consumption while scaling the underlying technology architecture. This requires having a deep understanding of the complexities involved in running data science operations at scale on multiple platforms, as well as knowledge of how to effectively integrate various workflow tools and technologies with available infrastructure resources.

Another issue is identifying strategies for accurately and efficiently distributing training datasets across systems to enable distributed analysis and accurate, fault-tolerant models. Additionally, ongoing scalability efforts must be considered when preparing for potential future demands on this technology such as new data sources or unanticipated usage trends, which can quickly render existing infrastructure solutions inadequate.

Thus, when attempting to scale open machine learning solutions effectively, decision makers must consider all these factors before making their final decisions.


We have identified the challenges of open and collaborative machine learning and raised $100 million to find innovative solutions. This investment will be used to develop the resources and tools to enable open and collaborative machine learning and accelerate its adoption in the industry. We will then explore various strategies and approaches to address the underlying challenges.

In this section, we will discuss the various solutions to the challenges that have been proposed or are underway.

Data privacy and security

Data privacy and security represent two of the most important challenges for open and collaborative machine learning. As organizations share data and use artificial intelligence for analysis, it is essential to consider how to protect personal data from misuse and keep it secure.

The European Union (EU) has established common privacy regulations across 28 countries through its General Data Protection Regulation (GDPR). In the US, states have begun to push legislation similar to GDPR. In contrast, the federal government has issued guidance on Complying with Privacy Shield Principles when transferring data to the US.

Organizations must be aware of their obligations relating to data protection whether they are part of a collaborative network or gathering information independently. At a minimum, entities should ensure that they have adequate controls in place, such as user access management techniques, encryption solutions and other security measures to meet compliance requirements. Furthermore, organizations should use automated processes that can generate audit records and securely store evidence with an immutable audit trail which can easily be retrieved from distributed storage.

Organizations may also want to invest in technology solutions that help monitor for data breaches or malicious intent before it is too late. In addition, many innovative approaches are being shared within research communities on how blockchain technology can help with securing AI-enhanced systems as well as promote trust among multiple stakeholders in an open learning environment. Organizations should ensure that their policies are up-to-date and continuously monitored by implementing measures such as regularly auditing implementations against best practices or revisiting consent model requirements before collecting personal information from individuals or companies participating in a collaborative model.

Building trust and transparency

The rise of open and collaborative machine learning can bring huge benefits, but several challenges must be overcome for such initiatives to succeed. Building trust and transparency is essential in ensuring the successful adoption of open and collaborative machine learning initiatives.

For collaborations to remain open, stakeholders must feel confident in the data they share: they must know what it is being used for, by whom and with what level of adherence to ethics. To ensure this trust is established, best practices should be implemented such as training participants on effective use and disclosure policies; introducing a policy or code of conduct that everyone involved agrees upon; providing secure access control mechanisms over the data shared; putting industry agreements in place; conducting risk assessments; and maintaining transparency throughout any given project.

In addition, multilateral frameworks should be established that are compliant with both local laws (such as GDPR) as well as international regulations (such as OpenAIRE). Such frameworks could consist of durable pre-agreed contracts between partners which lay out confidentiality provisions, license agreements (which include rights/access/use conditions), acknowledged & accepted standards for sharing data/code etc., agreed mechanisms for dealing with various kinds of risks (including antitrust), appropriate governance structures for participants at all levels etc. By implementing such safeguards, stakeholders can feel secure in their open collaboration initiatives while abiding by legal requirements.

Developing data interoperability standards

To create an effective and consistent collaborative machine learning environment, data interoperability standards must be developed. An open source machine learning platform can be used by many different organizations, so creating data interoperability standards for the platform is essential. These standards should ensure that data is accurately identified and interpreted across systems, enabling organizations to share and collaborate on their machine learning models within their organization or with external partners.

Data interoperability standards should include processes for correctly formatting the data before it is stored in a central repository and how it will be shared among multiple stakeholders. Additionally, these standards should define which specific data fields are required to produce accurate predictive models. Furthermore, they should establish a procedure for validating that the inputted data matches the exact type of model developed on the open source platform or downstream services.

Ultimately, developing sound data interoperability standards will provide a strong foundation upon which organizations collaborate on open source machine learning models without having compatibility issues between datasets from different sources. This will further accelerate the development of more accurate and advanced predictive models.

Ensuring data quality

Machine learning algorithms are data-driven, meaning their performance heavily relies on the data quality they are trained on. Data quality can be hurt by missing values, multi-collinearity between variables, incorrect encoding, irrelevant data fields and mismatched values. Generally speaking, it is important to have a comprehensive understanding of the data set and what it represents before attempting to build a model from it.

Several steps can be taken to help ensure data quality when building various machine learning models. Firstly, it is important to carefully review the existing data source the model will work with: Are the labels clear? Is there an appropriate amount of data (not too little or too much)? How might outliers affect predictions? Secondly, good hygiene should be observed while dealing with questionable information; gaps in knowledge should always be questioned and critically checked against one another for accuracy.

Furthermore, automated protocols should be used when consistently dealing with larger volumes of incoming or outgoing data — this can reduce errors associated with manual entry/export and provide more accurate results overall. Finally, strict monitoring procedures should also be adopted to identify any patterns that may indicate problems with accuracy or precision; this activity ensures continuous checks on the quality control processes within an organization’s open machine learning infrastructure.

Increasing scalability

To scale up the potential of open and collaborative machine learning, two main strategies can be implemented. The first is to develop enhanced distributed computing architectures such as those based on “containers” deployed across cloud computing infrastructures. In addition, efforts need to be made to increase the efficiency of storage resources by using compression techniques, as well as streamlining data collection and pre-processing activities. This could help minimize necessary system resources, reduce energy requirements and spur innovation through various associated data services available at scale.

The second strategy is to focus on scalability from an algorithmic perspective to make machine processes suitable for “big data.” Such optimizations include advanced linear algebra levels such as parallel sparse linear solvers (e.g., SUMSELS) that can work across multiple computer clusters and utilize GPUs or FPGAs where required. Other developments consist of modifications of common algorithms that decrease the amount of redundancy in master equations or enable alignment-free parameter searches (e.g., minimizing residuals with stochastic gradient descent). In all cases, it is important for developers to account for all the components necessary for real-world deployments rather than just optimizing performance from a numerical viewpoint—determining the most suitable resource allocation strategies (e.g., compute clusters versus cloud networks) should also be considered in more detail before launching global platforms for open and collaborative machine learning.


Our journey to raise $100 million for open and collaborative machine learning has been a difficult and rewarding. We have encountered numerous challenges and strived to develop innovative solutions.

In this article, we have discussed the key challenges and successes we have encountered, and have provided an overview of the potential that open and collaborative machine learning holds for the future.
