ID vs. Multimodal Recommender System: Perspective on Transfer Learning

Aggregated on: 2023-11-24 16:57:37

1. The Development of Transferable Recommender Systems The core goal of recommender systems is to predict the most likely next interaction by modeling the user's historical behavior. This goal is particularly challenging when there is limited user interaction history, which has long plagued the development of recommender systems, known as the cold-start problem. In cold-start scenarios, such as in newly established recommendation platforms with limited interaction sequences for new users, the early stages of model training often suffer from a lack of sufficient sample data. Modeling with limited training data inevitably results in unsatisfactory user recommendations, hindering the growth of the platform. Transfer learning is a solution that both the academic and industrial communities have focused on to address this issue. Introducing pre-trained knowledge into downstream scenarios will greatly alleviate the cold-start problem and help to model user interactions. Therefore, research on transferable recommender systems has been almost continuous throughout every stage of the development of the recommender systems field. From the era of matrix factorization based on item IDs and user IDs, transferable recommender systems had to achieve transfer learning for ID-based recommender systems based on data overlapping from both source and downstream scenarios. In recent years, there has been rapid development in multimodal understanding technology. Researchers are gradually shifting their focus to modeling user sequences using pure modal information, achieving transferable recommendations even in scenarios where there is no data overlapping between source and downstream scenarios. Currently, ‘one-for-all’ recommender systems that use large language models (LLM) have received a lot of attention. Exploring transferable recommender systems and even foundation models for recommender systems has emerged as the next frontier in the field of recommender systems.

Leveraging "INSERT INTO ... RETURNING": Practical Scenarios

Aggregated on: 2023-11-24 12:27:37

The INSERT INTO ... RETURNING SQL clause inserts one or more records into a table and immediately retrieves specified values from these newly inserted rows or additional data from expressions. This is particularly useful when you need to get values generated by the database upon insertion, such as auto-incremented IDs, calculated fields, or default values. Is this useful? Are there any actual use cases for this SQL clause? Don't ORM frameworks make it obsolete? I don't have definitive answers to these questions. However, I recently found it useful when I created a demo to explain how read/write splitting works (see this article). I needed a SQL query that inserted a row and returned the "server ID" of the node that performed the write (this, to demonstrate that the primary node is always performing writes as opposed to the replicas). INSERT INTO ... RETURNING was perfect for this demo, and it got me thinking about other possible scenarios for this feature. After speaking with colleagues, it was clear that there actually are real-world use cases where INSERT INTO ... RETURNING is a good fit. These use cases include situations in which efficiency, simplicity, readability, direct access to the database, or database-specific features are needed, not to mention, when possible limitations in ORMs hit. Even though you might still feel the urge to implement this in application code, it's worth looking at how others use this SQL construct and evaluate whether it's useful in your project or not. Let's dig in.

There are a lot of factors that could go wrong, especially when you’re developing a new service, deploying for the first time, or releasing a major feature update. In order to avoid any incident, this guide can help you in creating a blueprint for deploying and managing your application in production. Production Readiness Architecture review: I know this is the very first step before starting the development. But most of the time, as development progresses, a lot of things change, and the architecture of documents becomes outdated. It’s always a good practice to keep your document updated and verify once before the final release. Security: Security is another important pillar of a healthy service. This guarantees the safety of the data stored and shared across various sub-systems. Verifying and making sure all good security practices are followed before releasing the service will help in the long run. Service dashboard: A set of service monitoring dashboards consolidated at one place to provide a holistic view of service health and performance. This will help in understanding various components and usage of the application. Alarms: There are a few standard alarms like memory, CPU, GPU, etc. (threshold at 70% or 80%), which will let your team know about the potential issue and help mitigate it proactively. This event will help you put right methodologies to scale your application as required. There are certain data points that are unknown at the time of release, and it is fine to put an arbitrary number to raise the alarm for that kind of metric. Scaling, caching, and latency: Every application is built for a certain set of users and a certain number of transactions to support. But oftentimes, we need to be ready to scale up/down based on usage. It’s always best practice to put proper scaling factors to upscale and downscale the application based on various parameters to avoid any downtime or customer impact.Ensure a proper caching mechanism is implemented to cache and invalidate the cached data. This will help you maintain your SLA for low Latency. Beta testing: Beta testing provides a developer environment to test the flow, interactions, and end-to-end working of the application. This helps in building confidence. Gamma testing or UAT (User Acceptance Testing): It’s always better to test your application/feature with a certain set of Braveheart users who can provide feedback based on real usage. This will also help you to test your application before opening it to a wider audience. Runbooks: There are scenarios where certain sets of manual operations are required in order to perform certain sets of tasks, e.g., onboarding users, migrating existing customers, etc. These should be properly documented to avoid any issues. UT coverage: Define minimum coverage criteria, say 80% or 90%, and follow that to write unit tests. The better the coverage, the lesser the chance of a bug. Integration tests: UT is a great way to capture any issue with your function or a unit of code, but an integration test will allow you to test functionality as a whole. This will also ensure any future changes should not be breaking existing functionality. CM (Change Management) process: Point# 8 talks about Runbooks. While Runbooks defines the steps to perform the manual steps, the Change Management process will ensure proper steps are followed and document these changes. This will establish a best practice for any manual change and avoid any issues in production. CI/CD Pipeline: Avoid manual intervention as much as you can. A full CI/CD pipeline will ensure the changes are properly reviewed, unit tested, and integration tested. Dev testing: Perform as much dev testing as you can for all the possible scenarios you can think of. This will raise the quality of deliverable and ensures the safety of the code deployed in production. Incident mitigation plan: However better the system is designed and developed, there will always be some known or unknown risks associated with it. It is always a good practice to document a risk mitigation plan in case any incident happens. For example, what if the web server is crashed, what if web page redirection is broken, etc? A mitigation plan will act as a guide for any developers in the team to act quickly in case of an incident. “Develop the best; prepare for the worst!” Dependency documentation: If your application is dependent on some other application or applications, review it, document it, and create a mitigation plan for use cases like what if that service starts throttling, what if the service is down, etc. Logging: Ensure proper logging is implemented for all the scenarios like info, error, warn, or debug. Also, ensure no critical data is printed in the log and proper log level is implemented in different stages. Load testing: Performing a load test on your application will provide you with a number when the application might break. This will help you implement a proper scaling mechanism to avoid downtime. Rollback mechanism: What if a faulty deployment reaches production? What if some untested code reaches production? What if the deployed code is not behaving right in production? In order to mitigate any such issues, a proper rollback mechanism should be established and documented to roll back the application to a previously known state. This will help you to quickly restore applications' previously known state. A/B testing: In case of some major feature update, It’s better to collect metrics based on A/B customers. These metrics will provide insight into the feature released and its adoption. This will help you make the decision to roll out to a wider audience or roll it back. Roll-out mechanism: Alpha, beta, gamma, UAT, and Production. These are various stages that you could set up to target different kinds of customers. But in order to release your application or a major feature to a wider audience, define a proper rollout strategy like rolling out to a certain geographic user base, rolling out to a certain percentage of users, rolling out to a certain number of users, etc. Once the initial rollout is a success, then how to roll out to a wider audience. Conclusion In conclusion, having detailed documentation capturing various data points not only navigates a safer development but also provides safer deployment and healthy service.
