Consider the following table defining the sample inputs and corresponding target values for a perceptron model.
| Sample No | x1 | x2 | target | w1 | w2 |
|---|---|---|---|---|---|
| S1 | 0 | 0 | 0 | 0 | 0 |
| S2 | 0 | 1 | 1 | ||
| S3 | 1 | 0 | 1 | ||
| S4 | 1 | 1 | 1 |
What shall be the value of updated weights after applying all the samples S1 to S4 (in the order S1, S2, S3, S4) to this model. Given that the initial weights w1=0, w2=0, learning rate=0.1 and no bias is involved in the perceptron. The activation function for this perceptron is given below:
yobserved =
{ 1 if yin > 0
0 if yin < 0 }
Using perceptron learning rule: Δw = η (t − y) x, where y = 1 if yin > 0 else 0.
S1 (0,0,t=0): yin=0 ⇒ y=0 ⇒ no change ⇒ (w1,w2)=(0,0)
S2 (0,1,t=1): yin=0 ⇒ y=0 ⇒ Δw=0.1(1−0)(0,1) ⇒ (w1,w2)=(0,0.1)
S3 (1,0,t=1): yin=0 ⇒ y=0 ⇒ Δw=0.1(1−0)(1,0) ⇒ (w1,w2)=(0.1,0.1)
S4 (1,1,t=1): yin=0.1+0.1=0.2>0 ⇒ y=1 ⇒ no change
Final Weights: w1=0.1, w2=0.1
Answer: (1)
Match List I with List II
| List I (Operations on Fuzzy Sets) | List II (Description) |
|---|---|
| A. Intersection | IV. $\min(\mu_A(x), \mu_B(x))$ |
| B. Bounded Sum | III. $\min(1, \mu_A(x) + \mu_B(x))$ |
| C. Bounded Difference | II. $\max(0, \mu_A(x) - \mu_B(x))$ |
| D. Algebraic Sum | I. $\mu_A(x) + \mu_B(x) - \mu_A(x)\mu_B(x)$ |
Choose the correct answer from the options given below:
Explanation:
For a fuzzy set $A$, the $\lambda$-cut is defined as: $$A_\lambda = \{x \mid \mu_A(x) \ge \lambda\}$$
Hence, $(\overline{A})_\lambda$ is not equal to $A_\lambda$, even when $\lambda = 1$. Therefore, the statement “except when $\lambda = 1$” is incorrect.
✅ Final Answer: Option 3 is not valid.
| List I (GA termination criteria) | List II (description) |
|---|---|
| A. Worst Individual | I. At least half of the individual will be better than or equal to convergence value |
| B. Best Individual | II. Guarantees that virtually all individuals in the population will be within a particular fitness range |
| C. Sum of Fitness | III. Guarantees that the entire population to be of a minimum standard |
| D. Median Fitness | IV. Faster search convergence, guaranteeing at least one best solution |
