In the unit, called cookies, I have come across many mathematical concepts when doing the math problems. Inequalities were one of the concepts. Inequalities are the relation between two equations that are not equal. One of the first things that were done was to guess and check using random numbers to find the highest number of combinations that would still make the inequalities true. Also, in this unit it reviewed how to place inequalities on number lines; the open circle in inequalities represents greater than or less than and the closed circle in inequalities shows that it is either greater than or equal to or less than or equal to.Another mathematical concept is Systems of Equations. Systems of Equations are equations you deal with altogether

The class diagrams show the attributes, operation, class name sand also the associations that in this example is a bi-directional association with the multiplicity in each point where it can be:

Definition 10: Utility-list.: [6] The utility-list of an itemset X in a database D is a set of tuples such that there is a tuple (tid; iutil; rutil) for each transaction Ttid containing X. The iutil is the utility of X in Ttid. i.e., u(X; Ttid). The rutil is remaining utility of element X in that transaction. Two known properties of HUIs are used in this algorithm[6].

Computing frequent itemset 1: Given the database transaction id and all itemsets generate the database transaction id,itemsets format.Apply hash function to identifyy the frequent item sets ,support value and bucket count .

The useful systems ought to back the general techniques of the association, in the same way that the hierarchical methods ought to back the objectives and mission

The explanation for the answer to the given question is as follows: Hence, the current stock available is 180 units. To find out the probability of the company running out of the stock of 180 units within a time of next 3 weeks, let’s take ' z ' as a value that should be checked in the standard deviation table in order to find the probability...

P(A | B) is the probability of event A, if we already know that event B has occurred.

$C_t(i)$ represents the quantity of good $i$ consumed by the household in period $t$. Assume there exist a continuum of goods represented by the interval [0,1].

244. The timing components for a PLL are 15 k and 220 pF. Calculate the free-running frequency.

The fourth element defines the context values. The actual type of the context feature will be inferred by looking for the feature value pair within the previous initialization rules. For example, “negated” means if the corresponding context rule is matched in the text, then the target concept will be assigned the “negated” value for its “Negation” feature. It can be matched to “Negation” feature, because we have a configuration rule:

2. In some cases writing matching rules is very difficult due to incomplete information while in learning based approach using appropriate learning methods such as Naïve Bayes make “probabilistic rules” which can be done easily.

Let us analyze the case when the Roll-up procedure encounters a 0:n association Ti -> Ti+1 (Algorithm 2). To generate a virtual attribute vi, the Roll-up procedure applies 1) an aggregation operator Agg to an attribute aj and 2) a refinement operator Ref for the comparison of any attribute ak to a quantity c. Aggregation operators summarize the information contained in Ti+1, while the refinement operator is a filter on the rows used for the aggregation. The roles of Agg and Ref executed in lines:11-14 of Algorithm 2 can be clarified in terms of the following SQL query

Defuzzification is processes to get a non fuzzy control action that best represent the possibility distribution of an inferred fuzzy control action [12].

In our future work, we will be calculating the values of support and confidence on the multimode cluster using Apriori pruning. In this algorithm every item is considered as a 1-itemset. The support for each item is calculated and compared against the input support value entered by the user. If the support values of the item sets are less than the input support then those candidates are discarded and the action rules discovery algorithm only runs on the remaining attributes. This process is continued for 2–item sets and 3 and so until we have the support values for the item sets less than the input value. For example if we get the input support value to be 5 and the 4 item set attributes lead to support value less than 5, then we will be considering only the attributes that form the 4 item sets. In this method, we are pruning the attributes before the action rules are discovered and the algorithm only run on the attributes that form the frequent item sets. This avoids unnecessary combination of rules within the attributes. Instead of generating the rules at a later stage after finding all the combinations of rules, this prunes early to avoid unnecessary combinations. This greatly increases the time complexity of the algorithm and as well as space complexity. We are also planning to run this algorithm in the MapReduce Framework similar to the one we have done in this paper. This further decreases the time complexity and the action rules discovery
