As a result, the user receives recommendations that she/he is already familiar with or would find anyway, leading to low satisfaction. To overcome this problem, a recommender system should suggest novel, relevant and unexpected i.e., serendipitous items. In this paper, we propose a serendipity...
So, this problem can be expressed as the one of guessing a correct vector D of small weight, which defines a biased distribution. Here, the distribution of D corresponds to the weighted concatenation of uniform distributions among vectors of the same weight. We can thus study this problem in...
Guess. I can randomly guess the most convenient thing that helps solve the problem. This is followed by trying to find acounterexamplein some amount of time. If none is found, I believe it is correct. Now I will demonstrate this process on another problem:1923D, this time without pictures...
Beyond the cost of a robot, there are many design choices in choosing how to set-up the algorithm and the robot. For example, reinforcement learning (RL) algorithms require learning from experience that the robot autonomously collects itself, opening up many choices in how the learning is ...
One will note after Workshop Checkpoint #4 that the notebook contains a Head-to-head evaluation. This is out of scope for the DPR401 workshop, but if you have two models you want to train, you can configure the s3 path to the second model and perform a head-to-head evaluation. ...
Ethereum transactions inherit this logic but slightly change the composition of transactions. We no longer need to collect inputs to prove the availability of funds. Everyone already knows the current state, and therefore the balance of all wallets. If a user tries to transfer money that he doe...
Berkeley ran with this argument to claim that there could be no unexperienced objects, therefore everything must exist in some mind — if nothing else, the mind of God. The error here is mixing up what falls inside vs. outside of quotation marks. "I'm conceiving of a not-conceivable obj...
As an experienced R user, you will know that you can install R packages from a local package zip file. This is correct, and also easy to do. The problem is how to ensure that you have resolved all of the dependencies of the package you need, and to install from local zip files in...
In order to show that this algorithm is correct, we need only show that it visits an element with maximal variance and that the condi- tion for returning "false" is correct. Hence correctness is immediate from the following two theorems. Theorem 3.1. Without any stopping conditions, Algorithm...
We first need to define what we mean by “Computer Science Unplugged.” The term is used in several slightly different ways, and as we analyze its effectiveness, it’s important to be clear how the term is being used. The term originated with a collection of activities that were shared on...
