subsection{Recommending Unexpected Relevant Items} Once the forgotten items have been identified, we need to distinguish relevant ones from the rest. Given user taste shifts, as well as the changes in the system as a whole, not all unexpected items remain relevant, and consequently useful for recommendation. The key concept to identify relevant items is the extbf{relevance score} of the items at each moment. We propose four strategies to define the relevance score of each unexpected item. The goal is to recommend for each user only the Top $N$ items with highest scores.looseness=-1 subsubsection{Temporal-Distance Heuristic - TDH-2 } A simple strategy is based on recommending items that have been unexpected for long intervals. We assume that users are more willing to re-consume items that they have consumed long ago. The longer the period an item has been unexpected, the higher its final relevance score. We define the score of each item $i$ as the interval between the test moment $M_t$ and the most recent moment that $u$ consumed $i$ in the training set. Then, we sort the items decreasingly by this score and recommend the Top $N$ ones.looseness=-1 subsubsection{Relevance-Estimation Heuristic - REH-2} …show more content…
In this sense, we use the set of identified unexpected items as input for the UserKNN method. UserKNN will define the K-nearest neighbors of the target user $u$ and derive for each unexpected item $i$ a score based on the mean score assigned to it by the neighbors of $u$ in the training set. Then, items are sorted in descending order by such score and the Top $N$ items are issued. We implemented our version of extit{UserKNN} using Cosine as similarity function, such as presented in cite{adomavicius2005tng}. This version also incorporates the sample bias regularization approach proposed in MyMediaLite, with the original parameters cite{mymedialite}.looseness=-1
Exercise 7-13 I have to announce everyone in the group that we will not be able to meet the June 1 commitment to ship 100 operating tables to Southeast Surgical Supplies. To be clear, we only have 30 tables on hand as a report of this morning. However, this is not our fault entirely. Six months ago, purchasing warned us about shrinking supplies and suggested we buy as much as we could in advance for the next 12 months. We tried to follow their advice, but we were never be able to buy supplies in advance due to company’s policy about never buying more than three months worth of materials in advance.
Assign. 3 Andrew McConnon 13349871 1. In terms of specification of the framing in relation to the classic Ethernet protocol, it is specified by IEEE 802.3-2012.
I have chosen the predictive modeling assignment as a project to prioritize the three critical constraints scope, time and money of the priority matrix. Here, the project champion is my professor with whom I have discussed regarding the negotiation of the constraints to complete the project successfully with the given budget and time specified. Firstly, consider the budget for the project .It will be rigid as our professor gave me a SAS JMP software to get installed in my system to complete the project. So, money will be the least priority.
After examining the square table with grids to fit the triangle tiles, my calculation is 20 triangular tiles are used. Here is how I came up with the answer. Inside the table, it consists of four different shapes in triangle, rectangle, square, and a right-angle trapezoid. A square requires four tiles to fill. A rectangle requires two triangle tiles, as it is half of the square.
point (AP), or any central unit [8, 9]. This characteristic incurs several serious issues listed as follows. 1) Due to lack of central unit, central management like data collection or analysis is impossible. 2) To guarantee the routing, service discovery and data dissemination, many protocols in VANETs require the knowledge of global or partial topology of the network.
To obtain a numerical result for the form factors, first one needs the expressions for the distribution amplitudes for the $N$ baryon. The distribution amplitudes for the nucleon are studied in \cite{Braun:2006hz}. The DAs depend on various non-perturbative parameters which are also estimated in \cite{Braun:2006hz}.
Multilinear principal component analysis (MPCA) is a mathematical procedure that uses multiple orthogonal transformations to convert a set of multidimensional objects into another set of multidimensional objects of lower dimensions. There is one orthogonal (linear) transformation for each dimension (mode); hence multilinear. This transformation aims to capture as high a variance as possible, accounting for as much of the variability in the data as possible, subject to the constraint of mode-wise orthogonality. MPCA is a multilinear extension of principal component analysis (PCA).

Branching: • We can illustrate the concept of branching with a program that adds a list of numbers. • Same operations are performed repeatedly, so the program contains a loop. • The loop body is straight-line instruction sequence. • It determines the address of next number, load value from the memory, and add to sum • Branch instruction causes repetition of body.
• The four major systems each have its own database and interfaces had to be built for them to all communicate with each other. This is caused information to show in multiple formats and is difficult to reconcile. Providing accurate reports for banking and government regulators is very challenging.
There are several things that I appreciate from this class: \begin{enumerate} \item[1] \[ u_t=Ku_{xx}+Q\] To solve the above equation most of the time (For the sake of simplicity) we set $K=1$. This is how I solved similar type of equations in my undergraduate study. But you explained the importance of K. You said, for a small rod, K is not that important as in airplane (K is a material property). I will never forget this. I'm really interested studying PDE and to see the world through mathematics and then work for a new invention.\\ \item[2] You have introduced short and sweet ways of simplifying.
In semi-structured P2P network, the super-peers manage and organise the reputation values of their peers for resource selection and enhancing the result merging results. The reputation values of peers, however, are calculated by aggregating its documents ' reputation values. Technically, the super-peers build a 2-tuple of peer and documents reputation vector as esizebox{0.27 extwidth}{!}{$(P_{i}, (Rep(d_{1}), Rep(d_{2}), ..., Rep(d_{n})))$} where $P_{i}$ is peer $i$ belong to super-peer $S_{j}$ and $Rep(d_{k})$ refers to the document reputation value as calculated in Equation ef{Reputation_documents}. The peer 's reputation value is aggregated from other users ' feedbacks on its documents as in Equation ef{RepPeer}. egin{equation} Rep(P_{j})
3. Research Question and Objectives Our main objective is to design a web-based visual interactive software that can provide us a graphical interface for computer programming. Where basic general purpose programming facilities will be available like creation of modules, arrays and object orientation. Where we can achieve multitasking using threads and exception handling to catch exceptions.
1 What type of documentation did you see and inspire you? To my perspective, all those projects have been a trip toward the unconscious mind of the child and has released his/her deep emotional and visual experience. Also, the project has been a bridge between the self-unconscious (intangible) and language of self-expression (touchable) as “Artifacts”. To me as an educator with major study field in graphic and Fabric design, the outcome of the documentation has been a pure art which was occurred based on the unconscious of the child and affected his/her behavior and emotions. For the art, the timing of skill and the skill itself must be primarily unconscious responses.
