Let's simplify the given expression step by step:

### Expression:
\[
\left( (a)^{-1} \times (b)^{1/3} \times (a)^{-4/3} \times (b)^2 \right)^2
\]

### Step 1: Simplify the terms inside the parentheses

Group the terms with the same base:
\[
a^{-1} \times a^{-4/3} \quad \text{and} \quad b^{1/3} \times b^2
\]

Now, apply the rule for multiplying powers of the same base \((x^m \times x^n = x^{m+n})\):

For \(a\):
\[
a^{-1} \times a^{-4/3} = a^{-1 - 4/3} = a^{-7/3}
\]

For \(b\):
\[
b^{1/3} \times b^2 = b^{1/3 + 2} = b^{1/3 + 6/3} = b^{7/3}
\]

Thus, the expression inside the parentheses becomes:
\[
a^{-7/3} \times b^{7/3}
\]

### Step 2: Apply the outer exponent

Now raise the entire expression to the power of 2:
\[
\left( a^{-7/3} \times b^{7/3} \right)^2
\]

Apply the power rule \((x^m)^n = x^{m \times n}\) to both terms:
\[
a^{-7/3 \times 2} \times b^{7/3 \times 2} = a^{-14/3} \times b^{14/3}
\]

### Final Simplified Expression:
\[
a^{-14/3} \times b^{14/3}
\]

This is the simplified form of the given expression.
