The Internet might be filled to the brim with a lot of information about training as well as evaluating recommenders, but too much info could overwhelm you. Are you looking to get a clear understanding of the ways to beat different challenges revolving around a full-scale system? If yes, then start reading:
-
Dynamic Prediction
When you are dealing with a large user-base dimensionality, it could be a big deal to pre-compute every recommendation.
-
Optimizing the Time of Responding
When you successfully produce predictions dynamically, the total time you require retrieving them is extremely crucial.
-
Updating Models Frequently
When the system requires inculcating new data, it might be important to update the models on a frequent note.
-
Predicting Unseen Information
It could be a bit challenging to deal with the users and keep a tab on the swiftly changing product features simultaneously.
-
Problem with Cold Start
You may face a bit of challenge while handing the new users or products that lack a proper backup or history. However, this issue is highly solvable. You could use collaborating filtering or a content-boosted filtering solution to fix this issue. Using product depiction or distributes and user demographics for recommending different products/services to your intended users could be beneficial as well.
-
Plummeting Data
User Item rating matrix could be extremely sparse, as stores own numerous products and each of them won’t be rated by a lot of users. It’s a fact that only a handful of people actually rate different products. Owing to such sparsity, it becomes inefficient to train computationally. You may eradicate users or products from where they are not learning much. This way, you can minimize the sparsity of the rating matrix of user items.
-
Grey-Sheep Issues
Grey-sheep hints at those who have very inconsistent opinions and unpredictable behaviors. But, this issue is also solvable, and hence, you need not stress out too much! You should know that pure collaborative filtering may not succeed in fixing such an issue. You may opt for content-boosted filtering such as in the cold start issue to sort out this problem.
-
Similar products
Have you ever thought about how you would handle those products that are similar but have certain differences? As you are not going to use product depiction for collaborative filtering, you may miss out on the information regarding their similarities. As most of the online stores use different codes for such products, it could be difficult to find their similarities. But, fret not! This issue is highly solvable as well. The latent collaborative filtering is a certain algorithm that can figure out the intricate factors from different data. This algorithm works wonders for issues related to synonymy. This could be a solution if you have many products with synonymy.
-
Shilling Attacks Could be Challenging
It is indeed a tough nut to crack to deal with those who are striving to game the product recommendation systems. One of the most effective and easiest ways to solve this problem is to take adequate precautions and keep a constant tab on consumer behaviors.
