Here is my graduation design: Home Environmental Monitoring System design (PC on the temporary version of the computer. Mobile app version is pending). This system adopts STC12C5A60S2 single chip microcomputer. Combined with the sensor. The air humidity, air temperature, pressure, altitude, inlet temperature, water temperature, light intensity, soil moisture, combustible gas concentration, personnel in and

(actually is negative, forecast is also negative), false negative (forecast also negative, actually is positive).Precision (Precision): true positive (true positive)/predicted number of positive (positive) (predicted y=1) = True positive/(true positive + false positive)Recall (Recall): true positive (true positive)/actual number of positive (positive) (actually has cancer) = True positive/(true positive + false negative)So when we use precision and recall to evaluate the algorithm of the previo

minimum value (that is, the best fit to the data) fp1, residuals, rank, sv, rcond = sp.polyfit(x,y,1,full =True) print fp1 FP1 is a two-dimensional array with values of A and B. The printed value is [2.59619213, 989.02487106]. We obtain the linear function f (x) = 2.59619213x + 989.02487106. What is its error? Do you still remember the error function? We construct a function using the following code: f1 = sp.poly1d(fp1)print (error(f1,x,y)) We get a result: 317389767.34 is the result? Not

The process of building a machine learning algorithm: Quickly build a simple algorithm and test the performance of the algorithm with a cross-validation set. Draw the learning curve, check whether the algorithm has high variance or high deviation problem, so as to choose corresponding coping methods. Error analysis, to see the examples of errors in the algorithm, to analyze whether these instances have some systematic trend. Eval

The code for the 1.ANSI style is relatively compact.the following specifications recommend, better.The following is a complete specification of the module header with parameterGeneral 1bit, everyone is wire signal1 = gen_signal1_logic; This notation. Does not seem to be directly assign Signal1=gen_signal1_logic, does not declare wire signals;.Individuals generally use [email protected] (*), feel with a () so 1. Easy to follow the unity of SEQ 2. Easy to see *.Paper:synthesizable finit state

take an average of this evaluation mode.It is a useful algorithm to use the F-score algorithm to evaluate both precision and recall rates . The PR of the molecule determines that the precision ratio (P) and recall (R) must be large at the same time to ensure that the F score values are larger. If the precision ratio or recall rate is very low, close to 0, the direct result of the PR value is very low, approaching 0, that is, F score is also very low.At this point we compare three algorithms, we

Scala, inheriting a base class is similar to Java, with a two-point limit, and (1) Overriding the method requires the Override keyword, (2) only the primary constructor can pass parameters to the base class constructor. Markerfactory is a single case, once the definition is complete, its name represents the only instance of the singleton object, and the singleton can be passed to the function as if it were a typical passing instance. class Marker (Val color:string) {prin

classification model, which gives us a better evaluation value and gives us a more direct way to evaluate the good and bad of the model. One last thing to keep in mind, in the definition of precision and recall, we define precision and recall rates, and we habitually use Y=1 to show that this class appears very little. So if we try to detect a very rare situation, like cancer. I hope it's a rare situation where precision and recall are defined as Y=1 rather than y=0, as some of the fewer classe
